Leaf Margins, Paleoclimates, and Continental Movements

"All right. Dr ian miller. Thank you so much. For coming on the podcast. I'm really excited to talk to you about your research today but before we get there. Let's tell everyone a little bit about who you are in what it is you do. Oh thanks. I'm super excited to be here as well. And so my name is ian miller has said i'm a paleobotanist. I worked at the denver museum of nature and science. Where i'm a curator and i'm also the chair of the earth and space sciences there at the museum run a team of paleontologists and geologists as well as do my own research implants. Uh so that's that's sort of what i do now. I got to this point sort of chasing fossil plants in the american west. Were you always interested in fossil plants. Though i mean that that's an really interesting interest for like a child to get into you. Don't hear that a lot. I mean i was a dinosaur kid. I know a lot of other dinosaur kids out there but fossil plants. I mean it took me a little bit to get to the point where those were interesting but now i would argue. Sometimes they're more interesting than dinosaurs. But that's harris. The i think in a lot of circles is and i. I started all the time constantly. Battling the data serve posts. Make sure that the plants get the same sort of airtime So i was a mineral kit up at eastern washington state. So i was always after you know courts pistols. Pyrite things like that mine tailings. That were there around. The ranch grew up on. So i kind of discovered fossils a little late-game did have this interesting. Formative experience was really little. i was born in seattle. And there's lots of miocene rock around seattle right there on. I five knows eight. Ninety right outside of his supply of my grandfather took me to a road cut. Still remember pulling these fifteen million year old clams out of the hillside in their big like softball-size clams

YouTube pulls Florida governor's video, citing misinformation

"Youtube has deleted a video in which Florida governor rhonda's santa's and by the way a bunch of medical experts so actual doctors Questioned the effectiveness of having children wear masks to stop the spread of covid so the video was removed wednesday and there was so scientists was joined by oxford geologist Harvard professor Dr scott lists and another doctor from stanford and because they were contributing to covid. Nineteen medical misinformation. They had the they had the the whole video removed. So by the way to santa's at one point in the video asked if it was necessary for kids to wear masks in school and dr one of the doctors in response said children should not wear face masks. They don't need it for their own production and they don't need it for protecting other people either. Another doctor said it is developmentally in appropriate. It doesn't help on disease spread. And of course doctor said there's no scientific rationale or logic to have children wear masks in

What Earth Looked Like 3.2 Billion Years Ago

"We get into it quick very general refresher on plate tectonics the outer layer of our planet. The stuff we're sitting on is made up of a system of hard plates rigid blocks of rock that move relative to each other and they glide around on top of a layer of softer rock that makes up part of the earth's mantle these rafic plates drift around colliding causing each other to crumple or slide over top of one another. It's why we have most of our mountains and earthquakes in roger wants to know in earth's long history when those plates started moving answering that question was a bit of an adventure. Okay so roger to figure out when these plates started shaking and bacon moving around you had to go on a hunt for some very specific rocks. Where did that take you. Yes so we follow the old rocks. We go to the parts of the world Where rocks from three billion years ago are actually preserved And this is hard because actually of plate tectonics so play tectonics life recycles the surface of the earth over and over again only about five percent of the earth's surface represents the first half of our history. Oh that's really interesting in other words if you're a piece of continent three and a half billion years ago there's very little chance. He survived to the present day so specifically we went to an area. north australia. Called the pilbara so this is an area where there isn't a ton of turnover due to plate tectonics so you can find some really old rocks there. That's right yes. Just by the luck of the draw these rocks have been knocked around on the surface of the earth. It probably wandered all the way from the poll to the equator many times but Over the course of these three billion years it was never pushed down into the interior of the earth in which case it would have been heated melted. What is it look like roger. Yeah it's a really beautiful place and most of the terrains. Condie's green rolling hills with these kind of spiky kind of drought resistant. Grasses is better look then. Walk through sense yeah. It's prettier than it. Feels as what you're telling me exactly the same field season. We took these samples. I I made the grave mistake. Taking light-duty hiking shoes that also had some holes in it ended up duct taping my feet every day just armor at a little bit more against the the spiky grass so okay so you're you're hiking along you find iraq they are looking for you. Collect your samples. And then you take them back to your lab and try to determine their magnetic history. What is what is that me. Yeah that's exactly right. So we'd take the rocks from the field We keep track of how the rocks are are oriented so in other words wish science up and then we take it back to our lab and we measured that direction of of the magnetic field in the so turns out all naturally form rocks contain magnetic components. So i mean i mean. I knew that i knew that. Keep going on your then. Totally knew that. Yeah yeah so so. All natural rocks contain these Minerals so these little grains of material that actually are magnetic and they're actually behave like little compass needles. And if you take a take a rock any old rock and you measure in the instruments that we have You can detect the direction that these little magnetic grains are pointing. Wow so you you can literally take rock and say okay. We know this rock was pointing in this direction. That's exactly right. Yeah and The reason this is useful in our in our case is that the magnetic field of the earth exists at different angles in different directions depending on where you are on earth and specifically changing latitude if you go from one latitude to different latitude on on. The earth dangled a maniac field changes. So if you can measure the angle to make field in these rocks you can figure out what latitude through the form that. Wow okay okay so you you you figure that out and then let me know if i have this right then you compare them to nearby rocks that you know the magnetic history of you know which way they were pointing and that helps you understand like when they started moving By looking at our data of where this rock was relative to the equator and comparing to other studies We showed that this rock actually moved from position. Closer to the equator so in in the tropics of the earth to position that's farther from the equator so in kind of the mid-latitudes and and we can quantify how quick this drift was how quick this motion was and from that. We know that this does and was moving at the same rate at the same kinds of velocities that the modern continents move. Oh that's cool and so into you know when that happened because you know the age of the rocks as well. That's right so other people Other workers that have visited rocks before us. have looked at particular parts of these particular mineral grains in these rocks. Tie actually preserve information about how old they are So for each of these measurements of how close the rock was to decatur We can also put an age on that on that position so roger and his team by collecting and analyzing these very very old rocks and australia came up with an estimate. Their research suggests earth's tectonic plates were in motion at least three point two billion years ago. Several hundred million years earlier than we thought and another cool thing about rogers research. It weighs in on a peculiar geoscience mystery. So there's this very long standing question in earth science of how the earth seems to have had water surface for released last four billion years. Rogers says at that time. The son was probably about thirty percent fainter compared to today so the earth shoud have been completely frozen. But he says there's geological evidence liquid water was on the earth surface. Then you know one of the key ingredients that life to evolve on this planet so what could have made the planet warm enough for liquid water. You know where. I'm going with this. So one of the leading hypotheses for why. The earth managed to maintain equilibrium in temperature managed to have this thermostat. Is that plate. Tectonics causes the recycling of carbon into the earth and then also puts out carbon into the atmosphere and it does in such a way that the surface temperature is kept within the within a certain range. So are you telling me that. The movement of the plates that were living on is partially responsible for the development of our atmosphere and the temperature of our planet. Yeah that's exactly right. So this is a question that geologists have been pondering for like a really long time. How how cool it to add this piece to it to defined this out. Yeah yeah it. Felt very gratified to know that we have contributed to resolving this very old question. If feels like it feels like the effort was well worth it was worth the duct tape boots is. What you're telling me that's right. Yeah it was worth the the pokes foot every day every. Step all right roger. Will i really appreciate you. This super fun. Yeah yeah this is really

Ten years after Fukushima, Japan remembers 'man-made' nuclear disaster

"Japan then caused a nuclear power plant in Fukushima to go into meltdown. It was a traumatizing event, one that left the Japanese public and the world wanting guarantees that a nuclear disaster like that would never happen again. But can Japan make that promise? Some of Japan's most prominent earthquake, experts say. Not really the world's Patrick win has more. Okumura. Koji is a paleo seismologist. That means he studies earthquakes, old earthquakes that may have shaken the earth. When wooly mammoths were still around. It's like archaeology off course Quake. Archaeology of earthquakes. Sounds really nish on Lee. It's not. It's actually a matter of life and death because if they fault erupted even 10,000 years ago, that's a sign that it might erupt again in our lifetime, and you really shouldn't build a nuclear reactor anywhere near it. Because this could happen. In 2011 tsunami created by an undersea earthquake that squeaking noise, those air buildings crumbling in a torrent of water. And at the Fukushima nuclear plant. Waves pounded the power plant, causing a meltdown. It happened on March 11 and Japanese people still call it 3 11 shorthand for catastrophe now, Okumura. He is one of the top earthquake experts in Japan. And before 3 11. He was on a government safety panel as a caveat. He wants to say this. Nobody knew and nobody could have predicted kid. What he means is no one could have predicted this earthquake at this specific time. But Okumura and a few others were warning the nuclear industry that some of their reactors were sitting on potentially shaky ground. In those days, nuclear companies were almost regulating themselves. But after 3 11, Japan started over what they knew nuclear watchdog agency one with an unofficial motto, the new nuclear regulatory regime in Japan must be the world's strictest, which tracks with an acknowledgement that seismic risk in Japan is among the world's worst. Drew Richard is an author whose new book, Every Human Intention follows Scientists struggling to figure out how to prevent another Fukushima because that's what people want to hear. Alice that this will never happen again. Okamura, the seismologist says. That's almost an impossible request. We cannot tell when underwear a big Oscar eco cars, he can tell you this, like it or not. No nuclear problem. These profit pretty save Every nuclear power plant, he says, comes with risk, especially in Japan. Here's the deal. Japan just doesn't have much oil or gas. So starting in the 19 sixties, with lots of American help, it went heavy on nuclear to power, one of the world's biggest economies. And they did this. Knowing Japan as a lot of earthquakes again. Here's Drew Richard nearly all of Japan in nearly all the sites where nuclear reactors are built, our seismically hazardous. It's a nation that faces a level of seismic risk that's almost uniformly comparable to Seismically active areas of California on Lee, California has one nuclear plant. Japan was running 50 Woz after 3 11 that nuclear watchdog shut down all of them. It has since allowed only five to reopen. Watchdog is so strict that even experts who were advising the government before the disaster are effectively not allowed to join. That includes scientists like Okumura, Koji. And others who were warning the government, Okumura says. They just scrap the whole system for them, or the system was useless and I'm used to, and I'm useless to, he says. Other Japanese seismologists, who could join the watchdog agency won't because well, scientists don't want the spotlight the immense political pressure Okumura says. Right now, the agency actually does not have a solid team of earthquake specialist say Don't Tall, you know, professional scientists. Yes, it's a big laws. Drew Richard says. Most earthquake experts agree seismic safety is a real blind spot in a real weak spot for the current regulatory agency. And that's glaring because the Fukushima disaster was a seismic event. That's bad, Richard says. The current top seismic safety regulator isn't really an earthquake expert. He's more of a geologist, so it's a little bit like asking an influential kidney doctor to operate on your heart. Richard says most officials mean well, yet they face a traumatized public. Still looking to scientist for peace of mind the expertise of these earthquakes, scientists has been applied to Ah, fundamentally impossible question that question. Are any of those dozens of reactor sites absolutely safe from earthquakes. And as it turns out on the basis of the limits of human knowledge At this time, the answer is maybe we don't know. At this point half of all Japanese people just don't want nuclear power at all. Nuclear companies are pushing to reopen their reactors, but keep getting denied. Try again, Regulators say, Make it safer. Meanwhile, with most nuclear plants closed, Japan has had to import way more coal, dirty polluting coal warming the whole planet and people aren't happy with that, either. Just listen to these protesters. Follows at US. I'll call, you know, Call Japan. They're chanting, Okamoto says. There are no easy solutions here. He knows the public. Just want scientist to tell them their energy source is safe. What science can never be published again. It's the nature or not. You're Hauser. I admit he also admits that actually, he wants more nuclear plants to open up. That's coming from the scientist who foresaw Lay Fukushima like nuclear nightmare. Look, some of Japan's plans should clearly never open again, He says. They're just too close to fault lines. For others. The odds of another earthquake seem low enough that Japan should take the risk. He says. The country needs power. Yes, I'm afraid people against nuclear power may be hungry after me. Just try not to be too angry at me, Okumura says. He's just a guy who wanted to study prehistoric earthquakes, never imagining that pursuit could affect the fate of his country. And the entire planet. For the world. I'm Patrick Quinn.

NASA’s Perseverance rover lands on Mars

"Good morning, Scientists from Planet Earth will land another mission on Mars today. NASA calls the rover perseverance. NPR's science correspondent Joe Palka has been following this one. Good morning, Joe. Morning, Noel, Can we talk about the logistics of this? They have to get a hurtling projectile toe land safely on Mars. How is this done? Yeah. What's the big trick? It's going 12,000 MPH, and they have two landed it two MPH. No problem. Well, what happens is they're overs packed up into something called the Aero Shell, which hits the top of the atmosphere on Mars and Atmosphere slows the craft down and it's friction heats up. That's why there's a heat shield, but that does slow it down quite a bit. But then there's a giant. Parachute that slows it down further and then finally, there's something called the Sky Crane, which is a jet pack that flies over the landing site to the landing site, then lowers the rover down on a tether and then cuts the cord and flies away. But the interesting thing is, this is the same landing system that the last rover used called curiosity. But it's been made more up to date by the fact that it's got this smart landing system so that you can actually look for Ah, good place to land. If it doesn't like the first place it picks the confide to the next one. What is modern is all the computers and navigation systems are on this new rover. The design of the rocket engines on the sky Crane is actually 50 years old. Believe it or not, those engines all trace their way back to the Viking Landers. That's Joe Cassidy, He's executive director for space at Arrow Jet Rocket die in the company that makes the rocket engine. The Viking missions landed on Mars in the mid seventies, and Cassidy says the rocket designed depended on a special valve that made it possible to vary the Rockets thrust. Funny part is back in the seventies, We had a supplier that actually developed that forest with J. P L came back to us in the latter part of the first decade of the 21st century and said, We want you to do that again. That supplier was no longer in business. But luckily they were able to find an alternate supplier who would make the valve for them. Very luckily, what is perseverance looking for on Mars? Well, it's landing in a place called Jez zero Crater, which was they think a lake bed 3.5 or Lake 3.5 billion years ago, And the idea is there might might might have been microbes in the lake. So there'll be cameras on the rover that will study the appearance of rocks looking for things like stromatolites, which are structures left behind by mats of bacteria. They're also instruments on the rover that will measure the chemical and mineral composition of the rocks at the landing site, and Nina Lanza is a geologist at Los Alamos National Lab and the scientists on one of those instruments called super Camp. See, this is the kind of thing that a geologist needs right. We need both chemistry. What's in Iraq and mineralogy how it's arranged. So knowing those things tells a lot about the conditions under which the rock form then whether or not those conditions were conducive to life. I asked this excitedly. Could we be getting news soon, saying that there was life on Mars? Well, it's one of those news stories where people get very excited, but they will also say I'm from Missouri proof show me so that's actually the idea of this. They may see things that look like there might have been life there. But they say to confirm that they have to bring the rocks back to Earth. And in fact, that's what this mission is going to do. It's going to collect samples that a future mission will return to Earth. Okay. NPR Mars correspondent Joe Palka.

Cameras on Mars

"Behind the ideas that shave our future. The moore's twenty twenty rover contains an armada of imaging equipment from wide angle landscape cameras to narrow angle high resolution zoom lenses. But the cameras aren't just there to capture pretty pictures. Some of the cameras will help perseverance. Carry out its tasks as a robotic geologist looking for organic compounds could be related to pass life on mars. Other cameras will work together to acquire panoramic three d data that support route planning robotic arm operations and trilling working in tandem. Cameras will provide complementary views of the terrain to safeguard the rover against getting lost or crashing into unexpected obstacles and the cameras will be used by software enabling the rover to perform self driving over the martian to terrain to ensure the equipment is calibrated for resolution and geometric accuracy. Every camera on the rover must undergo an eye exam before launch so when those visionary science instruments begin capturing images on mars it will truly be an eye opening experience for all

"East and the other one towards the west. They flew around the world and they both met above the site of delfi when zeus all where they met he said. Okay this is the center of the earth so he took these giant stone and throw it there and from that point they say that the naval of the world was created and that was the site of delfi. Now there was an oracle there. Yes so how did that. How did the gods speak to the people at delfi. The story says that the people at that time which is around eight of years before the birth of christ they started seeing their goats going up on the cliffs and then hoping very happy very enthusiastic so the goat started hopping after visiting delfi yup and they followed them and they realized that they were inhaling. This vapes so vapor is coming out of the world out of the earth like a crack in the ground. There's a crack in the ground. And the ideology of managed to discover with geologists the managed to discover rox with signs of specific chemical contents of fumes. That will come okay so they realized that there was something magical. Competent back then signs was not as developed as it is now that they believe that this was a divine sign so everybody is believing. The gods are speaking to the people through a crack in the earth in delfi up in the mountains north west of athens and then how did the people who were in power capitalize on that to take advantage of that delfi became the most important placing the ancient world. Everybody all the kingdoms they would go there in order to find out. They should go to war if they should do. Big public works whatever. They had to decide if they felt. It was a very important decision. They would go there and nas the oracle for advice. So it's going into this mysterious temple and you've got priestesses and robes and crazy things and they really think this is the the oz on earth there would be these young girls that were inside special rooms underneath the temple of apollo and they would inhale vapes and starts talking in a way that no one would understand so they had priest that would decipher. We got to decipher as he wanted to today as a tourist. What do we see in delfi. Philippos see the ruins of the temple of apollo was the treasurer of the athenians. Which is building that the erected in order to commemorate because they took a lot of money. I suppose what's on the to the horse. Yeah so every city stayed with covid tone treasury the athenian you walk up to the temples and the theater and race course and so on and you pass all these temples that were treasuries collecting all that money. it's a fascinating place to check out one of the best sites from ancient greece. This is travel with rick. Steves with johanna wanna costa and phillips kind of cars. We're talking about greek mythology from the travelers point of view. You wanna if you're taking groups around whereas one site that you like to take groups where you really want to understand the greek mythology behind it. There are so many. It's all over the country wherever you were wherever you see mountains plans. Everything has a mess behind it. But there's a part of the peloponnese peninsula which is really unknown to the people come into the country. The heart of the peloponnese. The area called acadia very rich mythology over there. And one of my favorite stories is the story of where the name came from. So there was zeus. Who was a playboy. He was always in love with many women. Herro was his god. His wife hera okiro once fell in love with a beautiful girl. Her name was callisto and She got pregnant and hero found out and she really got mad. So zeus change their woman. Kelly stole to bear an animal and she was wandering around the mountains. The beautiful forest server. Katya she before that i should add. She had a baby and the baby grew up. His name was cass. He became a very good hunter growing into the forest and one day there was a bear right across from where he was so he took out his bow and arrow he was ready to hit the bear.

After Decades-Long Push, It's Not Clear Who Will Bid In Arctic Refuge Oil Lease Sale

"The trump administration has fewer than three weeks to go and is working to lock in oil drilling in the arctic. National wildlife refuge. It's holding an oil lease sale next week. Deacon handling of alaska's energy desk reports it's unclear. how much oil is under the refuge. Supporters of drilling in the arctic refugees coastal plain often point to its oil potential as a reason to develop the remote stretch of land president. Donald trump has described it as the gravesites of energy in the world. But while geologists say the rock formations oil seeps and old seismic results seem promising. The data available is still limited. We don't know very much about this area. David house neck is senior. Research geologist at the us geological survey and he helped with the agencies last assessment of oil potential and alaska's coastal plain back in the late nineteen ninety s. The usgs calculated anywhere from about four to twelve billion barrels of recoverable. Oil house. next says that's a whole of oil but also a huge range in part because it's based on seismic data from the nineteen eighty s. Technology has come a long way since then going into a lease sale in the coastal plain with the only data being thirty five year old. Two d data is quite unusual house. Neck says what's also missing from the usgs assessment is any data from actual wells in the refuge. There's been just one exploratory. Well drilled in the coastal plain also back in the eighty s on alaska native land but the results of that test well are a closely guarded secret confidentiality agreement and never an end date on it. Mark myers geologist and former commissioner of the alaska department of natural resources is one of the few people who have seen the results from the test. Well outside of the big oil companies that paid for it. So i can't comment on in terms of what i saw even though it was a lot of new york times. Investigation based on legal documents suggested the results were not promising but the amount of oil is just one factor companies will consider when deciding whether to bid in the alaska sale. Another is the money. Myer says it's already more expensive to drill in the arctic compared to say texas on top of that oil prices are still low after an oil price war and the coronavirus pandemic hit the industry. Hard low prices have fallen down to a level that we larry little capital for exploration in these companies. So that's one of the biggest negatives. There's also the controversy says weena gun. An analyst with the energy research firm would mackenzie. The refuge is home to migrating. Caribou polar bears and other wildlife and that has prompted multiple lawsuits to block drilling there. Some big banks site climate change and say they won't fund oil projects in the arctic. An amount of i guess public opinion the it wouldn't necessarily be good p for them to be seen as ruling and the article drilling and environmentally sensitive areas. But perhaps the biggest uncertainty of all is the changing administration. President elect joe biden says he opposes drilling in alaska's refuge although if leases are finalized before he takes office. It's not clear how he would stop it for npr news. I'm teagan hanlin in

Scientists Have Found Some Truly Ancient Ice, But Now They Want Ice That's Even Older

"It's chilly across the country today. Highs of just fifty eight in miami and sixteen in minneapolis which makes minnesota colder than an arctic as mcmurdo station but the cold weather doesn't last forever in the twin cities and in antarctica. It does ice their last hundreds of thousands even millions of years and as npr's nell greenfieldboyce reports that makes an arctic the perfect place to find some of the oldest ice in the world. Just how old is the oldest ice. On earth john higgins says. Nobody really knows you know. Would i be surprised at this point. We had five million-year-old is i mean. I'd be surprised. But not it's not unfathomable i think he and some colleagues recently collected ice samples in antarctica. That were later analyzed and shown to be as old as two point six million years. It's beautiful stuff when you pull out. The is it. Essentially as crystal clear accepted filled with tiny bubbles the bubbles contain air from when the ice formed and this trapped air is what scientists are really after higgins says if you want to understand how gases like carbon dioxide have affected the climate throughout history. You know you can't really do better other than getting a time machine and going back in time and taking an air sample then using these ice cores which physically just trap samples of ancient air to release that ancient air. All you have to do is melt the ice. That's the sound of a research camp manager in antarctica making drinking water by melting scraps of two hundred thousand year old ice in a metal pot to actually collect an analyze the release gases however ancient is has to melt in a lab. Sarah shackleton studies old princeton where she gets to watch the trapped air bubble out and that is something that i don't know if i'll ever get sick of watching. It's actually like pretty mesmerizing and one thing. That's released surprising every time to muse. Just how much gas is actually in the ice. She says it's a lot and samples from time. Periods undergoing past climate changes could be used to help make predictions about the future. One of the biggest questions in terms of kind of the modern warming and look anthropogenic. Climate changes helmich warming. Do should we expect with the amount of co two that we have in the atmosphere now. Antarctica has been covered by an ice sheet for at least thirty million years. But it's actually pretty hard to find really old ice. John gooch is a geologist. At the university of minnesota he says while snowfalls constantly add new layers of ice to the top of the ice sheet the oldest layers at the bottom can disappear. That's because of geothermal heat coming up from the ground so the rocks are giving off heat of slowly over time and so that has the potential to melt ice at the bomb. Still bits of super old ice like that two point six million year old sample can sometimes be preserved at the ice sheets edges the older snippets of ice. That we've been able to find come from places where the ice has flowed up against a mountain range and been exposed at the surface in those spots though. The ice can be all jumbled up and messy. It's not nice layers that have been laid down sequentially over a long continuous stretch of earth's history to get a neatly layered ice sample like that. Scientists need to drill straight down through the thick icesheet so far the oldest ice collected that way goes back eight hundred thousand years. Gooch says the goal now is to drill down a couple of miles to reach ice. That's older a million to two million years old whether or not we'll be able to find it at the bottom of the ice sheet where we can recover a relatively simple continuous record. Is i guess. That's the sixty four thousand dollar question at team from china has drilling underway a group from europe. We'll start in november. What everyone wants is i-i samples that cover a key time period about a million years ago. When there was a dramatic shift in the planet cycle of ice ages. Those had been coming every forty thousand years or so but for some reason that pattern ended and it changed to every one hundred thousand years instead unto us working on climate. That's a really big deal. Eric wolf is a climatologist with the university of cambridge in the united kingdom. It's a really big question as to why that change is fundamental tower climates.

Yesterday's a jack boone's who's a professor in the department of ece fisa goal in planetary sciences unto colorado boulder. He is also vice president images for academic affairs in blue sage for disuse system system. Jack while thank you. Joe is good to be with you. Thanks for doing this so you at your team. On deeply involved in the upcoming nasa missions to the moon including The designed to place radiofrequency absolutely on the far side of the moon and be kevin deemed really back there for almost fifty years. Now i know that china s landed. I was actually looking at some photographs that just gained today from From their lander. I israel in india. Almost got there but Fleas land properly. And so so. What's our interest. What's sudden interest in going back to the moon after fifty years. Yeah i don't know that. I would characterize as a sudden interest i think on the part of the science community and really the exploration community interest has been there for a while but what has changed in the last decade is the cost doing missions And the accessibility of the moon in this new era in which we have now. Private companies like spacex and like the blue origin company. Jeff bezos company They've put considerable private resources in developing new rockets of with reusability to lower the launch costs and also technology which was extreme in the nineteen sixties to try to get to the moon. All hannity vetted from scratch now is relatively straightforward at gill as you mentioned Even a small countries like israel Private companies have contracts with nasa to fly payloads. Now it's it's it's realizable to Envision going to the moon at a relatively modest cost certainly in comparison to the sixties and seventies. Yes so that's a. It's a very interesting phenomenon. Now it's it's almost like a business model question. Space is Blue blue horizon blue origin. Laura gin and that is another company. Lakers peterson things. Well lockheed you ally the united launch alliance which is the lockheed and boeing Company as well they all have these new generation of launch vehicles that are capable of going to so nasa in some sense outsourcing Some of the transportation right to so captain made a selection or are they going to do essentially multiple companies. Do it the the plan is to have monk multiple companies just like the commercial crew program To the space station there's boeing and spacex And for the case of the moon for the un crude landers that Landers that are just carrying payloads nasa has identified a out a dozen companies To be able to transport a payloads to the moon and at the same time. They're also undergoing competition right now. They selected three companies to design as part of a public private partnership the next generation of human landers. So that's the same. Mostly the same group that has spacex blue origin and the third one is is dynamic which is a company in huntsville alabama rate. So it's nassar's goal here is They are they going to take contracts from other other countries do send pedal to the moon in these companies. The the way this is working now is nasa is buying services so they're no longer buying rockets or landers which they will then own operate Instead the philosophy is To buy a ride for example a seat On a human land or or by space for a payload so these companies that are responsible for indemnifying Making sure they have a proper insurance for losses They take A bit of the risk and and then proceed along those lots now. What that means is that the companies then they own the intellectual property they owned landers they rockets they own the The other transportation devices. So that means they can sell seats. They can sell payloads to for example a european space agency Or the russian space agency or individual companies. That might want to puts a payload on the moon Investigation in this kind of a lower gravity environment so it's much more entrepreneurial than what we had before and it lowers the cost to the taxpayer for doing all these things by the artist program. Which is the new human programs. The moon the Recently released cost to get the first woman in the next man to the moon by twenty twenty four is a factor of ten less than the apollo program. Yeah it's interesting. I remember jack I was involved a little bit on the economic side of the next generation. Space legal program two thousand two thousand one two thousand two timeframe and this was a program was supposed to replace the shuttle and we did not go forward with it and i guess so. What was the arranged with the russian system to get their astronauts into space station. Yeah the the problem was that you might recall The shuttle accident that occurred in two thousand three And then president. George w bush declared that the shuttle really wasn't safe And that needed to be replaced and it took a while. We're still in the process of of fully replacing it. The last shuttle launch was twenty eleven If i remember correctly so in the meantime in order to get to the space station What we did is contract with the russians to use their soyuz spacecraft to go back and forth the space station so we. What we did is the buy seats. Those seats cost about seventy five or eighty million dollars so they weren't cheap but eventually got us back and forth. He said before we get the details of the Admission stack help philisophical question so way we have technology advancing the about conflict. Television's really taking off machines. Getting lot smarter What does sort of the basis for sending humans Could be not accomplished thing that human could do with machines if that's a good question i'm glad you answered that you ask that question because Excuse me i think what we're looking for now is is Really different mode for doing work on services like the moon or mars. Excuse me in that. We unlike apollo you had a single astronaut. Geologists such as astronaut harrison schmitt on all seventeen doing classic field geology. With a shovel to now advance unit twenty-first-century. We're gonna to do. Is i like to say we're going to bring Silicon valley with us to the moon. So we're going to bring advanced robotics. Be telly operated. That will use a machine. Learning artificial intelligence And will team with the astronauts so that they will these. These rovers advance scouting. They will identify interesting places and then the role of the astronaut is to make critical decisions on what to investigate What the samples. Look like i. i still think it's true. I've been told from my colleagues who are geologists stromer But who are uninsured. Scientists in that the difference for example between. Let's say the The curiosity rover on mars. And what it's been doing and having a human on mars that the work that the curiosity rover has done last seven years could be done in two days by geologists. a that's the difference and to also bring back. You know better selected samples and so forth. So there's no replacing humans and that's not going to happen anytime soon but you you do your point being. You only wanna use humans when you actually have to. Because their time is valuable and they're expensive and also Walking around even on the surface of the moon is dangerous. Because the you know the a space where the asian micrometeorites another possible dangerous but going into this new environment. I think what we're going to be able to do is reduced risk and improved efficiency. The i don't remember the numbers but a human Mission is about ten x the cost of a non human mission. Obviously the the efficiency and like you say what begin out of it different but guess on the cost side. It's about the fact of a magnitude different you know. That's hard to say because robots still are very limited in what they can do. They're just so many things that only humans can do is a little bit of apples and oranges but yet you're probably right that on the ballpark about a factor of ten. Maybe even more. But there's also much more than a factor of ten improvement in efficiency. So you know. Those costs will balance out and obviously the advantage of a human is You know they've been. The unexpected happens in michigan learning in As long as you have heard of data to teach a machine but then the unexpected happens machines. noel exactly. The rover gets stuck. It suffers a mechanical problem. That If you have a human there at least in the vicinity can help fix it. And move orders you know i think about for example servicing of the hubble space telescope and that was done five times by human astronauts and The astronauts such as john grunsfeld did to the servicing missions was very clear that the telescope could not have been repaired in upgraded by anything other than humans because the tab the complexity of the task the ability to be able to get in and To make repairs Make on the spot. Decisions just You know there was no replacing that so hopefully humans have a few more years of Do i think we've got many years to tell you the truth. I think it's going to be you know in reading some of the literature. I think it's going to be a quite a long time if ever that. We have truly Intelligent self aware machines can operate with the same decision making kick be very good at repetitive calculations outstanding job of there but You know making creative innovative entrepreneurial. Decisions were We're nowhere close to that yet So i do that. A multiple missions being planned An international collaboration so he's the first one that is supposed to take off as leave. Yeah artists is the new name for the human missions to the moon Artemis in greek mythology was the sister of apollo The twin sister of apollo. She's the goddess of the moon. So that's very appropriate. Since nasa has already declared bet up for that first landing which nasa has been planning for twenty twenty four would Would have that first woman in the next man on the surface the first expedition by humans to the moon in the twenty first century. So optimistic applaud. Its name the program programming program. Yeah exactly right so so andrade damasio multiple things going on And so do we have sort of a space station like that is going to orbit the out. Yeah in fact. That's honored design. And we'll be under construction in the next few years has called the gateway lunar gateway. And it's it's not like the space station in the sense of being gigantic And being really limited to that single orbit the gateway is really more of a spacecraft is going to have a pulse in system using a new generation of solar electric bad is ion propulsion That will be piloted for potential for optometry use in going to mars. I have just a couple of modules that will be there it will be a place where astronauts coming from the earth on on the orion spacecraft which is a it plus the space launch system is a heavy lift vehicle that will take astronauts the moon they will dock at the gateway and then they will get into a reusable lander go to the surface. Come back in that lander and then the next crew that comes in will do the same thing so you don't throw everything away like we did during hollow in the nineteen sixties again. The reusability idea is Is key to keeping the costs down so so it is more dealer so can't be attached as as alright right. Ds change in the future. Cab edge more against it. We can in fact The japanese space agency jaksa recently committed to fly a module And nasa has invited others such as the russian space agency to think about them attaching A module as well so it definitely is modular. That way you can add habitats you can add laboratories And can can grow over time. But it's also the the idea is that it's going to be long duration spaceflight and it's away way from the earth's magnetic field so you've got the full range environment of what you would have going to mars. So i think nasa all also looks at. This is a prototype of the vehicle that would be sent to mars. Lucchese david some Conversations yet again. Remember that To go to mars you would rather start off. Start off from the moon. Is that still thinking or that. Exchange i don't think that's been decided but there's this potential real advantages of a loon. First of all launching from the moon versus the earth requires much less thrust. What what we call delta the. That's the change in velocity to Get off there. Because there's only one sixth gravity on the moon and secondly if we're successful in mining water from the minute we know now there's considerable amount of water at the polls of the moon That's hydrogen and oxygen. We can convert that potentially into rocket fuel. You wouldn't have to bring that from earth so the costs associated with launching some could be substantially reduced in doing this from the moon versus from your so people are actively working that right now and seeing if that might be the way to go i of think that might end up being How missions to To mars or undertaking so under optimus Are there plans to actually create a habitat a big enough habitat for people to stave or extended period of time. So nasa has designs. And once again i should mention this is. This is all international Insa is involved. The european space agency is involved in providing a module for the service module for the orion. It also will be working on the gateway. The canadian space agency is providing the robotic arm And the same will be true on the surface The idea is that the first few missions will of just get started That first nation in twenty twenty four is planned to go to the south pole of moon. Will we've never been to before and look at the water. Ice situation there but Over time by the end of the decade the expectation is that will have multiple habitats. And we'll have people staying there for long periods of time like the arctic station. It's run by the national science foundation. The mcmurdo station as called in which you have a number of scientists come in and visit for anywhere from a few weeks to staying for year here so salama but when the next generation space program was in progress space. Too big big project. I would imagine spacex Others cab this business plan so what's the clamps time Do that The gay yes. So it'll be somewhere between three and five days to get from the earth and you're right about. The tourism spacex already has a fide a japanese businessman. If i remember correctly who has bought a A ride not the surface of the moon but to orbit the moon on a spacex vehicle. Sometime in a in a few years but the it'll be in a three to five days to get to the gateway and then Another day to get down to the surface. So i fully expect by the end of the decade especially given the accessibility to the moon by the private sector and by isa companies That they will be selling seats to wealthy individuals to spend a A summer holiday on the moon is so if the if the gateway is expandable perhaps Taxpayers can make some money nasa. Well it might be. Yeah but but once again this is. The transportation for the most part is probably not going to be through nasa but by these individual companies who own their own rockets their spacecraft and now they will sell seats to to wealthy tourists. yeah and so You you mentioned the european space agency. You mentioned the canadian space agency of so. Is this like the space station. A larger collaboration or those are the three major ones. Yeah it is and you're right. There are Oh gosh there's probably a dozen or so. Companies countries rather involved in the international space station and nasa envisions this much the same thing And i to. I order all the countries that are involved in. The international space station have been invited to become involved with the gateway And so as i mentioned several have accepted with With enthusiasms others are still keeping that around and take a quick break jack. Benny come back to talk about the radio. Frequency of savitri on the far side of the more that you're designing you bet sounds good. This is a scientific sense. Podcast providing unscripted conversations bit leading academics and researchers on a variety of topics. You like to sponsor this podcast. Please reach out to in full at scientific sense dot com back Jack you're talking about upcoming missions to the moon Some of the manned mission some of some of the technology that you're sending up there there is a gateway bridges like the space station but attested propulsion its zone. Sorta are based entity source. And it's more dealer things could be attached to it. That may be subject is imploding. Creating that a launchpad so to speak to go to mars perhaps habitats that a large announced a mining for water mighty for hydrogen and other things and so he the program is called autonomous. So could be portal light program and underneath optimists. There are various things being planned right. So what are the The primary objectives all of those radius approved betas projects. I should say under under optimus. Yeah we'll go. let me let me start off by just looking at the difference with The apollo program because the apollo program ended fairly abruptly once the political goals were reached and it was never Really a sustainable program so Nasa and i think all of the governmental space agencies are looking for is for arsonist to be the beginning of a sustained presence on the moon and in space and using the moon as a stepping stone for human and robotic exploration of the solar system including getting the mars so the philosophy of artists is really quite different. So you're there the stay So you need to figure out how to live off the land. So that does mean as you're saying mining's water being able to grow crops being able to manufacture Equipments the habitats themselves from the From the of the regular or the soil material so using the the kind of advanced manufacturing capability three d. printing Electrolysis so that's a really different approach. And it means that what will be worked on is not just get there but a flag in the ground rather in full of soil and return on instead it means You know how do you figure out how to be there for the long haul so that means than learning how to to excavate how to build How to really maintain a life in a in a certain sense of independence. Part of the reason you want to do all that is because that's exactly what's going to be

The world's highest mountain officially just got a little bit higher

"Today. China and appall agreeing for the first time announced that Mount Everest, which straddles both countries, is now 29,032 FT. Tall, slightly more than Nepalis previous measurement. About 13 ft higher than China's BBC environmental correspondent Levin saying Khadka joins us from London on Skype Levin, How do you measure this thing? How they do it? Hmm. Now that's the question, isn't it? How do you do it? How do you measure the highest mountain in the world? All right, So look, I don't want to confuse your audiences. It's lot off lot of technology a lot off complications there. But basically what they told me was, it is easy to find out the top of the mountain. But what you need to find out is the bottom of the mountain. How do you find at the bottom of the mountain and that will help them to find its height. So that is where you know the sea level thing comes in, so the Nepalese authorities they used the building goal as the base And then from there, they call this precise leveling again now that sea level needs to reach in the Everest region. Okay, so that's illegal. You know, visibly, you have to reach using your tripod. You know every 50 m or so they did for 250 kilometers and reach the Everest region and that watch as if The mountain is standing on the sea. You know that? Yeah, they calculated. That's one of the ways of doing it. But there are other ways as well well, but I understand that the two countries have argued about the other side how high it is. So when China and measure the mountain in 2005 it found a mounting was 8000 Internet 44.43 M So that it said was the rock surface. Now That's why there was this disagreement and China back then wanted Nepal to agree to this. This hide that found and appall disagreed because the Nepalese How did the snow on top of the summit? You're right. So yes, the the figure of Nepal government was using Woz, including the snow cap. They had this difference all these years. And then finally, you know, Nepal told that okay, This has to be decided once and for all, And then, in the meantime, if you remember in 2015, they were just major earthquake. So many geologists believe that that might have impacted on every side and therefore they have to find out if there was any change. Look, we understand that there's a Almost like a competition among these great mountains, which is the greatest, which is the tallest, which lends itself to the competition among climbers who can climb. You know these peaks and you've just explained that this extra footage really comes from below, really where that climb starts. So just this is really make any difference. When I speak to mountain is what they say is well, it doesn't make any difference to us. But then clearly, you know when countries are using these figures than definitely it becomes a huge issue and also quickly just to remind you when the two countries China and Nepal announced the height this morning, they didn't use the word Everest even once Nepal stuck to it its own name Sagar Mata and I know the Chinese kept on talking about trouble. Oma all these years, you know, Everest, the name itself and the height that was given out. You know it was it was initiative during the British colonial era and so on and so forth. China strictly believes that you know it owns up that mountain to some extent with the park. Everybody feels they own it in some way, But you know nothing. Hearing this news. I've just decided I was going to climate. But now I'm not 13 more feet. That's a bit much by China's standards. BBC's environmental correspondent Levin Sing Khadka on the new height of Mount Everest. The world's tallest mountain is a little bit taller Now, Naveen Thank you, my president.

"geologist" Discussed on Your Online Coffee Break

"Infrared astronomy has confirmed the first time water on the sunlit surface of the Moon previously NASA had discovered evidence for water in Shadows of craters. But this new discovery has incredible implications for the possible loss of water as a resource as NASA returns to the Moon joining me. Today is lunar geologist. Dr. Sarah Noble as she discusses this incredible Discovery and its implications for the future of space exploration online coffee break. Thank you so much for joining me. Really? Appreciate it. Great to be here. We always love to talk to our guests about their space journey where their passion for space began understand years around ten years old. You wanted to become an astronaut. Can you test just wage more about that? What inspired you there? Yeah, I you know, I don't know it just it would just one day it just popped into my head. Oh, maybe I could be an astronaut and it just sort of stuck. You know, I mean, I grew up in the rural Minnesota there was not a lot of you know spaces pre-internet. I'm very old and and there wasn't a lot of you know space And scientists and and whatnot around me, but I was just I was fascinated by space. I started to climb onto anything I could find about space anything I could read about space manage to go to space camp when I was a teenager and that sort of really cemented a lot of things for me. So now I love how you had sort of a personal experience with the moon when you're a graduate student. Can you tell us a little bit more about that? Sure. I I was working in late in the lab one night. I'm working on some lunar samples birth. Lunar soils and and I was I was walking home from from the lab and it was a full moon and the moon was shining down. I looked at my hands and they were sort of sparkling and a few grains of lunar soil sparkling. I'm on my hand wash my hands and up at the moon and like this dirt came from there and like I had this like Epiphany about the moon as as this geologic place that's you know, not just you know up in the sky, but it's a place with rocks and dirt sand like a place we've been and can go back to and it was just a a real moment..

Sea Hunt - It's Still Alive - Cave Diving

"Off It's time for another installment of Sea Hunt. It's still alive. And today we're going back to season 2 episode 21 for cave diving cave diving Premier package on May 24th 1959 in this episode. Mike is working with a geologist George Brian who is searching for uranium in an underwater cave. George has been doing his diving with his wife Susie up until now but needs Mike helped to explore further and do more work. They're diving off the boat Olympia with its Captain pops. Mike and George hop in and swim down with her watertight geiger counter. Mike has a doubles and George's in a single tank as they approached the cave. They put the ear pieces from the geiger counter into their ear and they take out the probe Mike's off the Geiger counters chattering like magpies. All of a sudden things start to shake Mike is spinning around. George is at the cave entrance. It's an underwater landslide. When all the turbulence is over, there's a huge Rock blocking the entrance to the cave and George is trapped inside under a pile of rocks. Mike shines his light and injured signals back. Mike can't budget Iraq. So he heads back to the surface. He says he has less than an hour before Susie becomes a widow. Mike tells pops. He needs the ship-to-shore radio to call the pier and they need to bring out some big hooks to pull away the Rocks. He's talking really fast. George only has 46 minutes left now. He tells Pops that it's real bad. Now they're desperately scanning the surface for the help from the pier the boat rounds the point and gets there within 14 minutes Susie is on board in her scuba gear bag ready to help George is down to thirty minutes Suzy insists on helping Mike despite his objections. Now Mike and Susie make it to the caves entrance and struggle to get the anchors attached to the large Rock. Finally. They get them in place and Mike's ends up a flare for the boat to pull the rock the boat strains when suddenly the anchors Breakaway failure Susie is desperate trying to get into the cave. Mike is trying to calm her down and he said she has to be rough with her in the commotion Susie's air hose gets fouled and they have to Buddy breathe to the surface. Susie climbs on board the hooks won't work. She's crying pops is trying to comfort her. What will Mike do now? Here's where things really get interesting. Well, Mike just happens to have some Dynamite on board just in case you know, pop says that's kind of risky. Mike says there's no other option but like pops was in the Seabees in World War Two and says they use Gophers to carry a line through a pipe. So they concoct a plan to use a fish to thread the line off The Rock. Well, it just so happens. There's a barrel on Deck with a live fish might takes out the fish and ties a line around its tail and heads back down to the cave with the fish house and a speargun. He checks to see if George is still alive looks at his watch time is running out. He lets the fish go into the cave ties the fishing line to the heavier line and tries to log the fish back with his light like tries to grab the fish. It's too fast time for the speargun. He's got one shot takes dead aim, and our hero fish is a goner my calls in the fish pulls the line through and now has the heaving line around the rock ties the bowl and shoot a flare to the surface and Lifeboat cranks up its engine. Finally The Rock is pulled from the entrance my crushes in freeze George and brings him to the surface. Mike yells out. I got him and pop lets out a big Yahoo back on the boat. George and Susie are reunited. Mike is lounging now. They say George's leg will be okay. They're talking about the fish that saved George Susie says that were fish was Mike Nelson. As the episodes ends, they're talking about pops idea from when he was in the Navy and Pop's final line is I wasn't in the Navy. I was just the Seabees. Hm wonder what my CB friends would think of that now you might recognize George if you're of a certain age, that would be Herbert Anderson better identified with Dennis the Menace his father Henry Mitchell. Well, that was certainly not what we think of when we think about cave diving using a fresh to thread a line around Iraq is a little out there but if anyone can do it, it would be Mike Nelson on Sea Hunt. off

Greenland Melting Fastest Any Time in Last 12,000 Years

"Greenland is the biggest island in the world and the ice sheet that sits atop it is massive. The pile of ice is so thick that it extends more than ten thousand feet above the ocean, and if all the ice were to melt and go into the ocean global sea levels would rise by twenty four feet everywhere around the world, Jason Bryner, Geologist University at Buffalo the ice sheet is melting of course but just how much compared to the past Brenner team did a computer simulation of. The southwest portion of the Greenland Ice Sheet, which he says is a pretty good proxy for ice melt across the entire ICESHEET. The researchers plugged past climate data into that model to hind cast rather than forecast the past activity of the ice sheet, and they then checked the predictions of the past shape and size of the ice by looking at piles of rocks and boulders and dirt on Greenland, today, which outlined the edges of the ice and the simulation was in good agreement with the actual situation. Using that require. -struction of the ice sheet over time the team could then compare the ice sheets historic losses to those happening today under human caused global warming, and they determine the greenland is contract to lose more ice this century than during any century in the past twelve thousand years possibly four times as much ice. The results appear in the journal Nature. Ultimately it's up to us how much ice melts you know humanity has the Knob the carbon knob and that knob is going to influence the rates of Iceland. Greenland. Ice Sheet. If the World Goes Net Carbon Zero by twenty, one, hundred, for example Bryner says ice loss could stop entirely at the end of the century according to one model that was what kept me from being completely depressed about our study. Dozens of countries have already announced goals to go net zero by the middle of this century so far the US is not one of them.

Scientists discover nearby 'diamond planet'

"TWINKLE twinkle little star how I wonder what you are like a diamond in the sky. That familiar nursery rhyme may actually have a ring of truth. This is innovation. Now, bringing you stories behind the ideas that shave our future geologists explain how diamonds are formed carbon and other carbon based materials are put under tremendous heat and pressure over millions of years and are then pushed up from Earth's mantle through volcanic eruptions. But recently, scientists are talking about a new form of diamond one that. Exists in outer space scientists have discovered a super earth. They believe is a diamond planet. The star system located about forty light years from Earth is primarily made up of carbon iron and silicon millions of years of pressure and heat have slowly turned the planet's carbon. Mantle into diamond. Now, as much as one third of the planet's mass may be made up of the crystalline stone and as NASA exoplanet. Program continues the search for planets beyond our solar system. It is safe to assume we will find other shining examples of geologically unique worlds in space

1980 eruption of Mount St. Helens

"So my episode today. is about the nineteen eighty Mount Saint Helens eruption. So now, we weren't alive then even though we were not alive, then it was you know years until Jillian. Many years. Until we were born. We are in our. Mid Twenty. S. So we're very youthful. Yeah. We say what's a CD or whatever I don't know anything I couldn't even pretend to be a teenager because I have no idea went technology. Don T TIKTOK ON THE TIKTOK You know on the TIKTOK so. Nineteen Eighty Mount Saint Helens eruption has a lot of parallels to what's going on in the world today, but it's an interesting story. So to to start with for our non US friends and Non West Coast friends, I didn't know the details about this when I started researching it but Mount Saint Helen's which is known as a lot lot to the indigenous lets people and Lou wit. Luella cloud to the click a tat is an active stretch of Okano located in. Skamania. County. Washington in the Pacific Northwest region of the United States I. Apologize to the Washingtonians. If I pronounced Skamania county your Skamania county incorrectly. I'm sure I will get an email about this. Fifty miles eighty kilometers northeast of Portland Oregon Ninety, six miles or one hundred and fifty four kilometers south of Seattle Washington. So to get a sense of where Mount Saint Helen's is. If you're thinking of both Washington state and Oregon is roughly like. Square ish rectangular ish in shape with Washington, in the north and Oregon just below. Mount Saint Helen's is in the lower left quadrant of Washington state near the border of Oregon. and. She's roughly halfway between Portland, and the Portland Oregon and Olympia Washington, which is the Washington state capital. Okay. also relevant northeast of Mount. Saint Helen's is what's called Spirit Lake. And there's a bunch of little rivers and creeks in that area just due to like the geology of the area but almost directly north of the mountain is the north fork toodle river. River toodle or Poudel T. O. U. T.. L. E. Title River. So. Also? Mount Saint. Helen's takes its English name from the British diplomats. Lowered Saint Helen's is a friend of explorer George Vancouver who made a survey of the area in the late eighteenth century The volcano is located in the cascade range is part of the cascade volcanic arc, which is a segment of the Pacific Ring of fire that includes over one hundred and sixty active volcanoes and for the record before the explosion mount. Saint, Helen's stood at nine, thousand, six, hundred and eighty feet high. So. They knew it was part of the ring of the ring of Fire Okay Yeah Yeah So. They knew as part of the ring of fire. It had experienced some activity throughout recorded history but it. It remained dormant basically from its last period of activity in the eighteen, Forty S and eighteen fifties. So by one thousand, nine hundred had been more than one hundred years before there was any like really significant activity that includes ash like little burps and like any kind of flow or anything like that. So. At this point people were pretty complacent thinking nothing's going to happen anytime soon it's fine like it's a dormant volcano for all intents and purposes until we get to the spring of nineteen eighty. Okay. So, there were several small earthquakes beginning on March fifteenth of that year indicating that magma may have begun moving below the volcano also just as an f. y. we talked about natural disasters on episode sixty one which was called here I am rock. You like a hurricane I talked a little bit about that about volcanoes in that episode. So if you want to refresh your memory about the basics of what's in a volcano check that out episode sixty one, it's very good. Thank you. So on March Twentieth Three Forty Five PM Pacific Standard Time, which everything will be NPS T. Shallow magnitude four point two earthquake centered below the volcano's north flank signal the volcanoes return from one hundred, twenty three years of hibernation. A gradually building earthquake swarm saturated area seismographs, and started to climax at about noon on March twenty fifth reaching peak levels in the next two days including an earthquake registering five point one on the Richter scale. A total of one hundred and seventy four shocks of magnitude. Two point six greater were recorded during those two days. That's a lot. Yeah. So geologists in that area are like look is no not a great sign. Initially. There was no direct sign of eruption but small earthquake induced avalanches of snow and ice were reported from aerial observations. So this mountain is shaking and you know stuff is falling off. It's not it's not nothing. At twelve thirty, six PM on March twenty seventh phreatic eruptions which are explosions of steam caused by magma suddenly heating groundwater. So that's like a quick like spur. Of, like Ash and Steam K ejected and smashed rock from within the old summit crater. Excavating a new crater, two, hundred and fifty feet wide. And sending an ass column about seven thousand feet into the air. So you yeah, knock. Great. So by this date along, east trending fracture system had also developed across the summit area. So there's cracks forming in the summit. This was followed by more earthquake swarms in a series of explosions that said ash even higher above there. And most of this ash fell between three and twelve miles from its fendt. But some was carried hundred fifty miles south to bend Oregon or two hundred and eighty five miles east to spokane Washington. So the ash went pretty far and those who were like what the What is happening here? So? then. A second new crater and a blue flame were observed on March twenty ninth.

"Martin watched as a geologist on a ridge two miles closer disappeared in an avalanche of ash and smoke in Martin's radio went silent tie in Marianna Kerney were listening and watching from another rich they told me in nineteen ninety nine that they sped down narrow dirt roads we left our van when the service nothing but ash clouds of all these columns there was one nine felt like gosh maybe we won't get our hearing we were very fortunate to have survived and have a clear road and other people of course I had a really are bad rough time out of it like Mike Moore who was camping with his wife and two young daughters thirteen miles away in nineteen ninety nine more showed me photos of a colorless landscape smothered in volcanic ash our major color that we saw was our Tim when we camped that night after trying about eighteen hours to get out not being able to make it eighteen hours trudging through deep bash climbing up and over fallen trees still Moore told me our situation doesn't compare to what other people went through because he and his family were rescued to me the most pathetic story is of the gentleman that was an extremely good physical shape and he made it fourteen miles before he finally collapsed and went to sleep and the body was found with his lungs and his trachea and his mouth and his nose just filled with ash in all fifty seven people die the timing magnitude and direction of the eruption surprise geologists it first blew out sideways with more energy than an atomic bomb Seth Moran is the chief scientist now with the cascades volcano observatory there was no sign that it was going to happen at eight thirty two in the morning of may eighteenth there was no short term indication and there've been a lot of optimism that there would be signs and so it was actually pretty devastating in the days following that folks were thinking that they'd missed something they hadn't according to their data so they have to be ready for sudden eruptions with little warning at mount St Helens in other volcanoes vulnerable communities have been identified and warned and there's more monitoring now that's a lesson that we certainly learned at mount St Helens and for sure it's influencing the putting out instruments on other volcanoes that you know in some cases have interrupted in thousands of years but there's the potential for them to do so if that volcano wakes up back in nineteen ninety nine tie Kerney was philosophical about surviving the nineteen eighty eruption it's something that doesn't happen very often in a in the lifetime of a human being and in this nature it's nobody can stop it the last big scare at mount Saint Helens began in two thousand four and lasted nearly four years but eruptions were relatively minor the watching and the waiting continue for the next one for NPR news I'm Howard Berkes and now we have a story about a survivor she was born in nineteen eighteen when the Spanish flu had begun in Europe she survived that of course and World War two the depression after all that so few Boris immigrated from Greece to New York City in the fifties and then in March a few weeks after she turned a hundred and two she was diagnosed with corona virus her daughter Effie stress CD's didn't have much hope we just didn't think she would be able to make it the doctor told us we couldn't come to visit her but if it gets really serious and towards the end they would allow us to come and see her so we were prepared for that the forest was it Mary manning Walsh nursing home in Manhattan where she was already familiar to her doctor tamer Merson and she's very talkative lady Huskies the person that will often come up to the desk and start up a conversation with the nurse or with myself she speaks Greek only so in my case I use Google translate on my phone and when she stopped doing that is when I got worried she got a fever that day she tested positive and move to a covered floor through phone calls and video chats her daughter saw her get worse the second time I spoke to her she kept saying how sick she felt and that she couldn't even talk on the phone the CDC says that eighty percent of people who died of covert nineteen in this country are sixty five or older but despite her age and despite her congestive heart failure of voice got better after two weeks Dr Mircea has no idea why but he gives her the credit she is just a very strong patient and she had a big part in her own recovery here even when she was like really sick the doctors said she was still kind of spry she would joke around a little bit our smile he would come in and I thought yeah that's my mother her daughter and her doctor marveling over Sofia Boris who survived covert nineteen at the age of one hundred and two this is NPR news.

"A geologist talking about covert nineteen about well let's find out so in my book in my writings I've done a lot number lot commentaries on the relationship between warming temperature related deaths related to warming versus cold and then we see that there's somewhere between fifteen to twenty times as many people die due to cold as due to heat and that's it for this is related to my research on climate change global warming because of course the powers that be in the I. P. C. C. and the U. N. panels all say that it was going to get warmer we're all going to die and it's going to be really bad famine pestilence and engine I've heard I've heard the the opposite is true this is coming from medical professionals now that they're they're looking forward to it warming up yeah yeah and that's what I'm the end of the commentary I just rode in your listeners can actually go it's the lead blog story at my website which is inconvenient facts dot X. YC in the study that was just released here earlier this week that relates to the state categorically well they're they're proposal it's still early in this process but that it's a warming they were experiencing coming from spring this really leading immersing into Wuhan area has been the spread of the virus to stop in there relating that to warming temperatures in the fascinating thing with this story is there a plug and play a game these hot spots around the world from a wall in France northwest United States Wuhan and others are all located in a fairly narrow band of the same latitude and relating it to both temperature and humidity well north northern Italy actually thrive northern Italy was the source the epicenter of the hot spot in that country up near the outpost right end which falls right into this band and I've got a I've got a map that I've included on my blog post today provided it's fascinating to see this this band so they they're speculating that the viruses actually somewhat limited by temperature and humidity what know pretty soon if they're white but they linked it back to the laboratory studies on corona viruses in the narrow band of temperature and humidity in which they thrive for their their thesis is that animal warming of course this band that they mapped out a couple weeks ago and warms that'll move northward in the northern hemisphere but that they're also saying this is it this time of year warms we start getting warmer temperatures pretty rapidly and that it is a band of liability for the virus will actually move up it as we move forward there nor can and the less populated areas so you can you can look for more cases in Alaska and Canada for example then are right present right now as the rest of the continental U. S. warms up is that what you're saying well that's one of the things they foster speculated about but if managing art a lot of these are very sparsely populated areas and for this virus to to thrive and prosper you need to move L. A. B. it needs to be spread in highly populated to host it needs a warm breeze right yeah right so this is this will all play out but again we know that we know that the cold periods the other thing they said was the original hot spot also we're in this narrow band of temperature these areas none of these areas of the original hot spots ever got below freezing nor were they in much higher temperatures one of it when they first started and it all started during the lowest temperatures of the year all of these things contributed they sank to the to the the spread is for the good news is if they're right this will be this will probably act like other coronaviruses that have strong seasonality effect he stated with with the other coronaviruses that it's it's virtually nonexistent in the summer period well which means that we could see a recurrence of this next fall and winter and course it might it might mutator who knows what's going to happen by them but but you're right at least we get a respite here and maybe prepare for this when we went to the into winter next year a little bit I thought not none the less it's it gives us nothing but doom and gloom about this haven't we now for weeks and you know this is I think it's welcome news.

"All the time. I've posted pictures on behind the black repeatedly showing this. But the problem is that the atmosphere and temperature of Mawes are such that it's impossible for water to flow on the surface. And so that means the atmosphere and the temperature had to be different in the past and geologists planetary geologist. Have not been able to come up with a good model to make that happen. And this is a great this is a fundamental geological mystery it once was possible for water to flow on its surface. But no one can figure out how that was possible there in the atmosphere. Once thicker and therefore Warner warmer, but none of the data. We have so far provides enough information to structure a model that would solve this mystery. And that's really what we got here. It's just just accentuating that mystery have photographs of sand dunes on Mars Bob one from Toronto seven one from twenty nineteen. They look exactly alike. Yes. Adult day. Well, this is one of my post on behind the black. You know, I do this all the time multiple in, you know, I'd find an interesting image in the Mars reconnaissance orbiter, high resolution database, and I post it. And so I came across a picture that was labelled a monitoring changes doing changes said, well, let me go see if there's any images at the same place. And of course, I found one a dozen years earlier. So I posted in both of them behind the black to show little change has occurred in those dozen years. And what this really tells you is that things do change on the surface of Mars, these days, very, very, slowly if at all doing on earth you. Expect doing to actually change on a yearly cycle wind rain and the seasons would make it move. They could change. Well, that's not happening here and on March things are generally pretty stable the atmosphere is too thin to really change things quickly even with the light gravity. So that tells us something.

"Eight geologist geologist i think we see quite a lot in the landscape so firstly i think the present day landscape is not necessarily it's not a landscape that's been currently shaped by water it's a landscape that's being shaped by wind rozhin processes largely so most of the landscape forms that we can see the present day are shaped by millions of years of wind erosion basically but the rooks themselves that we're investigating and some of the landforms that we can see show clear evidence for water activity so that it's certainly clear that water played a major role in the early version of the sediments in gale crater so i've seen pictures of uc the these deltas almost looks like it show what you compare that to two on earth it's very very similar that's right i mean that's the model we use so you know the reason i'm on the team and other there's a lot of other terrestrial geologists on the team the people who study rocks on earth is that basically we're using our experience of reconstructing ancient environments on earth and playing that back on mars you know what i can do is i can say go down to the dorset coast look at a series of sedimentary rocks on that drastic coast and i can tell you a story narrative of what that landscape not only look like paint your picture of that but also tell you how that evolved how that landscape evolves through environmental change be at climatic change or just changes in processes and what's remarkable is that we can now do that on mars because actually the same physical processes applied i mean sedimentary particles are moved by physical processes physics and the same physics applies among us she was malls once a wet planet like earth a watery planet so that's a heated debate in march.

"Harlan brits who was a kind of radical geologist one of those radical geologists fear is that in fact these geological formations had been caused by catastrophic flood or multiple catastrophic floods but that happened in recent time and by recent time how recent thirteen thousand fifteen thousand years end of the last ice age more or less right but certainly within the time of modern humans and is this controversial almost like some throwback to some youth pastor saying all the dinosaur bones come from the flood or right right and it was incredibly controversial it was he was drummed out of the rebel geology society while even the rebels you know he was he was too radical and he spent he spent many years trying to demonstrate his theory or trying to prove his theory and his theory was that as the ice sheet that had covered all of canada and portions of north erica retreated it left behind an ice dam which all i can do is is make reference to game of thrones because that's what everyone is thinking to future ling's of the game of thrones was a they thought they have their moms hbo password yeah i suppose it was a diversion that kept us from reading or acting with our children but a giant wall of ice giant wall of ice that was nine thousand feet thick like a a huge glacial sort of dam in a in a canyon that would have been like keeping this lake behind the rocky most two miles front to back and the lighter than game of thrones by the way.

"Nothing else orbiting a son resembles eyed green blue planet and until a couple of decades ago that was the end of the story the idea that there might be other planets out there some of which might resemble earth was she speculation then in the nineties all that changed astronomers lent spot planets orbiting of the stars sometimes that spot to stars brightness damn is a planet passed in front sometimes that siesta wobble eversoslightly as it was tugged by planet's gravitational pull today thousands of bees xl clennett have been discovered which begs the question are any of them anything like but these comments a light years away meaning we have limited information to go when we think about exit planets we kind of have to think about very few observable mass radius something about orbit and maybe down the line something about at that and that's it this is came in unto born he's an exile planet geologist so with those four parameters i have to build a plant and kind of understand everything going on understanding xl plans could teach us which ones are more like a and this would provide please ultimate quest to find life on on the world finding candidates for worlds that could support life requires astronomers to first observe whether an egg so planet is in its does socalled habitable zone where the distance is just right for the planet to be able to support liquid water but the habitable hoon concept is great for sort of a first cut rate is that planet in a habitable zone yes it's likely to have liquid water but there's a lot more steps after that that say well okay is it too much water well cannot produce continent that are sort of of the right composition to aid in these geochemical cycle um what is what is likely hood of having magnetic field these are all sort of secondary things that the more that planet has in its favour the more sort of the geologist in me would be comfortable with say yeah go ahead and invest a years worth observation really dig in if there's one thing that observations of told us so saw.
