"Pick a mission that has been very delayed that you'd like to talk about. Well, there's two favorite ones to look at. And those are the JWST and the SLS launch system. Right. Okay. Let's pick one. The space launch system launch system. So let's start with GW's T so back in the 70s. 80s, 80s, when people were envisioning, yeah. So back in the 80s and 90s, when people were envisioning the telescope that would succeed Hubble. What kind of budget time frame were they anticipating? Well, they were expecting a time frame around 2010 and a budget of far less than $5 billion. Yeah. I'd seen as early as, yeah, 2010, 28, four $.5 billion. But kicked up to 4.96 in the late 20 aughts when it was given the 2014 launch date that they missed. Yeah, I'd even seen lower like 1.6 billion. Like early early on, there were amazing mistakes made. Right. Okay. And then the reality was 2020 one late 2021. 10 billion ish dollars. Yeah. NASA's contribution strictly for spacecraft development. So this is the money spent before the sucker even launches. Came in at 8.8 billion as of October 25th. And we're still waiting for the final numbers to come out for what went into the rest of 2021. And that was only the NASA part. So beyond the NASA part, there was an additional 200 million from Canada. And then, of course, the European space agency threw in four instruments and the launch for another €700 million. So yeah, we're looking at 10 billion to get that sucker into the air and then for the next 5 years, almost another billion of support it, but I'm okay with those costs. Right, right. So, okay, so let's just put that set that aside. So we get a sense of the scale. Now let's talk about the space launch system. Yeah, so I don't even know where to start with that one. Well, what was the plan? I mean, I guess, what was the, like, I see why you're having trouble picking it apart because there is sort of a smooth, continuous goalpost changing set of requirements from the early 2000s until now. Yeah, so they had multiple different rocket types. There was the Orion program. There was the constellation. There was constellation, and then things got switched over to space launch systems, which it looks like we may have at least one launch of and at the same time that all of that government funded government contractor built specifically for NASA chaos was going on. We had space acts off to the side. They do have NASA funding, but they're also funded through the services they sell. There are commercial launch provider. I think I can I think we can roughly compare apples to apples with James Webb here. Like the original constellation program, potentially the successor to the space shuttle, the going back to capsules with a big rocket was during the first term of George Bush. Yes. The second, and I'm feeling like it was like 2004 ish..

"And antiquarks, three identical generations of particles, 23 parameters that you can adjust anywhere you want is horrible, but it works. So we found the first crack, meaning that there's a 5th force out there beyond gravity. Beyond the nuclear force, a 5th force out there, which could be the next octave of a vibrating string. String theory may give you the next theory beyond the standard model. Next, Lisa is a satellite that the European space agency is funding, which will give us baby pictures. Baby pictures of the infant universe is a gravity wave detector in outer space that'll pick up gravity waves from the instant of creation, giving us baby pictures. Baby pictures of the infant universe as is coming out of the womb. And maybe just maybe we'll find evidence of an umbilical cord. An umbilical cord connecting our infant universe as an emerges from the womb to a parent universe in the multiverse of universes. That's well within the cards as the European space agency and NASA launched Lisa into orbit in the coming years. Next, we have dark matter. What is the universe made of? Well, atoms, right? Wrong. Most of the universe is not made of atoms. Most of the universe is made out of dark matter. And we're clueless. Clueless to understand what is dark matter. It holds the galaxy together, is invisible. That's why it's so hard to prove, but no one's been able to determine what it is. String theory predicts what dark matter is, it again is the next octave. The next octave of the vibrating string is dark matter, which makes up most of the invisible universe. Then next, the Japanese, the Chinese and the Europeans, are laying the groundwork for the next generation of Adams measures, much bigger than the one that I built when I was in high school. And we hope to find evidence of the 5th force by creating particles that are only seen beyond the standard model. And then the 5th testable way to prove the theory is to look for deviations from Newton's laws of gravity. Newton's laws is based on the idea of the inverse square law. If you double the distance away from a star, gravity goes down by a factor of four. But why four? Why not 8? Why not 16? Because we live in a three dimensional world. The world is three dimensional. But string theory says, nope, the world is 11 dimensional. And we are a three dimensional bubble. A three dimensional bubble floating in a much larger 11 dimensional Nirvana. So it is Nirvana, nirvana is 11 dimensional hyperspace. And what is our universe? A bubble. A three dimensional bubble floating in, which is expanding, and that's called The Big Bang Theory. Anyway, so we're looking for deviations from Newton's laws of gravity, which could then clinch the existence of these higher dimensions. So these are 5 experimental ways that we can test string theory. So let's say flashing forward. That the God equation is, I don't know if the correct term would be solved for, but that we arrive at the answer. The quest for a theory of everything comes to an end. What are the possible applications? Because I'm sure there are people listening just to step into their shoes. We're saying, this is incredibly fascinating. I could listen to this and explore this for many, many more hours. But I'm worried that 20 or 30 or 50 years due to climate change, we will not have the luxury of pursuing these types of questions. What are some of the applications? What are the outcomes? Well, some of the greatest philosophical questions of all time. What happened before creation is time travel possible can not be answered using the standard model, Einstein's equations break down at the instant of the Big Bang at the center of a black hole, all the interesting questions, well, they break down at the point where string theory starts. This is called the Planck energy, ten to the 19 billion electron volts. That's the energy of the Big Bang. And Einstein's equations fail at that point. That's where string theory comes in. For example, what happened before the Big Bang? If string theory is correct and there's a multiverse, we now can say what happened before the Big Bang. The Big Bang was the collision or the splitting of universes. And we hope to get pictures. Pictures verifying this picture with Lisa, a satellite to be launched into outer space with funding from the European space agency and from NASA. And so that's when application is to define what happened before creation. Is there really a multiverse? And what's on the other side of a black hole? Well, most theories say that a black hole is a dot, a dotted infinite density, anything falling into this dot will die. But that's the old picture. We don't believe in that anymore, because these black holes are all spinning, spinning rapidly, and it's spinning black hole collapses to a ring, not a dot at all, but a ring. And if you fall through the ring, you wind up analysis looking glass. The ring is a wormhole. But our wormholes stable. If you watch Star Trek, you realize that one of the problems with wormholes is that sometimes they collapse on you. So you're halfway through the wormhole and whoops. It collapses on you and cuts you in half. Well, the stability of wormholes can be calculated with string theory. String theory is a theory of everything, including wormholes, and we should be able to calculate the stability of these wormholes. And then time travel is time travel possible. Well, as I mentioned, Einstein's equations do a lot of time travel. But how stable are they? That is, when you enter the time machine, will it blow up? Hawking thought so. I can redid the calculation show that time travel is possible in Einstein's equations, but and this is a huge but as soon as you enter the time machine, it blows up. Well, it blows up because, again, of quantum corrections. But string theory allows you to calculate these quantum corrections. That's speculate about them. He speculated that they are infinite. But maybe they're finite, in which case you can go backwards in time and visit yourself as a child. And then perhaps the greatest application of all is the fact that the universe is dying. Physics is the ultimate death warrant for our universe. Physics says the law of thermodynamics says the second law says that in a closed system, everything must eventually rust, decay, fall apart, and die. In other words, trillions of years from now, the universe will consist of dead black holes that neutron stars and the temperature will be near absolute zero and we'll all freeze to death. This is called the big freeze. And it seems that the laws of physics are a death warrant for the universe. But you see, there's a loophole here. In a closed system, the universe must die. But you see, maybe the universe is not a closed system. Maybe there are wormholes, which means that the universe is an open system, and the second law of thermodynamics does not apply for open systems. And so what do we do? Trillions of years from now, we'll be so advanced that we'll be able to play with the Planck energy, create wormholes to order and create a lifeboat. An interdimensional lifeboat that we can flee into and go to another younger warmer universe and start all over again. In which case we'll have yet another universe to mess up..

She actually grew up on a Christmas tree. While I feel bad, having to cancel. It looks like we're going to be in here for a while. You got, what do you got to eat? You said some snack bars? Oh, yeah, yeah. You want the chocolate raspberry glazed honey covered sugar. Give me the lard bar. That sounds good. Let me just have the peanut butter Oreo covered honey glazed. Oh, you know what? I actually have a thermos of eggnog here. Just a second. Cheers. Cheers. Actually, you are you hot? I'm hot. I'm okay. It's warm in here. I gotta take my jacket off. Actually, you actually don't look so good. I'm a little claustrophobic. It's cramped, you know? It's Titan here. I just feeling a little. It's called an elevator. Anxious, yes. But you know what it's like. It's like, do you remember that space capsule that we rode in a few years ago for the holidays? Yeah, yeah, for that government experiment. Right. Yes. Yeah, well, so we're just walking down the street. It was a beautiful holiday evening and we were reminding our own business and then all of a sudden this van just comes screeching out of nowhere. Look out. What is it? Who are you? What's going on? Calm down. Come down. Yeah, calm down, make yourself in the floor of the van. Which one of your bombs is Robin hillman? Uh, that'd be me. Think about shaving sometimes. You must be bob boyan. That's Robin Hilton. No, you're bob boy. Okay. You ever think about ironing your shirt? I'm in radio. Okay, listen, you guys don't look great. You've got some important work to do here. Who are you? What is this all about? Who are you? Who I am is not important gentlemen. That's probably true. The job here is what's important. The European space agency and its Rosetta spacecraft recently landed a probe on comet P 67 with us. You people ever follow the news? This has been in the news. I think I did see something about this. It's a comet 300 million miles away, very, very important, important space mission here. Yeah. So what? What does that got to do with it? Detected a mysterious song coming out of the comet. Nobody knows who it is or what's behind it. I'm going to determine to find out we are determined to find out. What does that have to do with us? We like song. Isn't it obvious? It's a song. We want to find out what's going on with this song. We need to send two music experts in space to investigate them. That's really cool. Yeah, that's nice. We couldn't find any music experts. So we grabbed you guys. Well, look, this isn't really a very good time right now. You know, we were about to grab dinner and it's the holiday mother. Your country needs you. Get a shave,.

"When they didn't have clouds, we're actually able to enjoy the sky at night with beautiful, beautiful things, including Steve, which people keep saying they've understood. But you're right. It really has been an amazing year for professional researchers working to understand active galactic nuclei looking for planets. Heck, we found a planet in another galaxy. Yeah, yeah. And galaxies without dark matter, pointing to dark matter has to be real and not gravity. It's the theorists are actually winning this year. Astronomers have found planets of ever more increasing speed around their stars. They found one that goes around its star every 8 hours. Which is pretty mind bending. And we've also found them at distances. We didn't think they belonged that. There was a binary system that a massive ten Jupiter sized planet was found hanging out where it would be the outer part of the Kuiper belt in our own solar system. Yeah, yeah, and you've got this like a star that shouldn't have planets with a planet that shouldn't exist at a distance that we have never seen before. And it's all there. Yeah, no problem. It all exists. Yeah, so but it's funny. It's kind of hard to now go like, oh, let's talk about the planets that have been discovered because there have been thousands. I mean, Tess has just been turning up hundreds and hundreds of planets. The Kepler data still turning up planets plus all these other ground based observatories have been turning on planets as well. I hate to say it, but I now no longer even read the press release when someone announces the discovery of a planet. I'll skim the title, but I won't generally go any deeper because there's just so many planets now. I'm waiting for the one that says and this list contains the 5000 of the confirmed planets. Because we're just edging up, I feel like we're two or three publications away from it. And being able to say that we've gone from 9 to 8 to 5000 known planets is kind of awesome. Yeah, right now we're at 4884 planets. Known with another, just shy of 8000 candidates. And of those 3600 are actually planetary systems with multiple planets in it. So just to think that we're at this point now in the process of knowing of so many planets, it's absolutely incredible. All right, let's address the elephant in the room. JWST. Yeah. So one of my more on brand tweets that I spotted was last night, it was announced that the press conference about the launch date for the delayed telescope was delayed. And as we went into recording this episode on December 17th at four 30 on Eastern Time, we still don't have an update. Last we heard there was a communications issue between JWST and its rocket. They were pushing for a launch on December 24th. The European space agency had a tweet that has subsequently been deleted, confirming launch on the 24th rumors on the Internet because of course there's rumors on the Internet are that NASA wanted a big announcement and usage just jumped the gun. But NASA needs to read the room. We are done with big announcements. We just want news and real time..

"A simple stuff. Yeah, plugging MT wells pretty easy to do. So this is essentially leakage. This isn't causes an industrial byproduct of creating things. This is waste. It's funny you say that, Dana, because I would actually describe it as sort of maybe not waste but lost useful product because essentially natural gas is predominantly methane. And so if you can capture it, you can sell it and gain perhaps additional revenue that you're effectively just getting or letting loose into the atmosphere. In terms of leakage, I'd say most of it is accidental fugitive, if you will. But a lot of the times it is intentionally vented just because the infrastructure is in set in place, the capture it and yes, they're like losing value by doing it. So one would assume that incentives are a line for the oil and gas industry to not want to lose. This potentially sellable product. Why is there an important role for governments to play in trying to restrict or enforce the oil and gas industry to actually handle some of this leakage? Yeah, so I think a lot of the leakage and the reason behind it is that companies and operators don't actually know it's being released. It's an invisible gas. It seeps out of the upstream sector, maybe through a loose valve or compressor and those emissions are broadly unknown to the operator. And they don't want to go into take the effort to track that down and figure out how to sort of reduce it. So it really, I think, at least from a government perspective, it's more about putting pressure on the company's two after you start doing it because it is definitely possible to do. And it's that pressure is built up for a number of reasons and one part is just that we're better able to monitor and verify large emission events using satellites. So satellite technology has progressed very rapidly over the last few decades. And we're now at the stage where using, for example, the Copernicus satellite program that's run by the European space agency has been used by data providers to pick up large emission events above 5 tons per hour, for example. And that gives you an idea of what's going on in places where geographically the conditions are aligned for you to be able to get good satellite data. And that recognition along with efforts by NGOs and by other organizations and by oil and gas producers to basically measure emissions using other techniques closer to the ground has given us a much more granular picture of emissions than we've had in the past, and that's also been really at the heart of our recognition of me.

"Really the crux of it. From what i can gather. And these are called dark clouds or dark nebulous. That name of course is very descriptive. Because when you look at it it's essentially a black void in space when you see them and that's because the dust is so thick that no light comes through them from behind so you could see you see this ominous huge ominous black shape that surrounded by thousands of stars. But from. But nothing's coming through and it's really if you know if the pictures well made. It looks really like something weird mysterious going on now. Inside these these cocoons of these dark nebulous is actually a fascinating place because the lack of starlight helps create a really really cold colder temperatures than you think it's essentially it's heated up one thousand that would have if the starlight can get through. And what's actually the only thing that's really heating it cosmic cosmic rays so. I didn't know that that's that's very very interesting. But that allows very exotic chemistry's when you have these these elements altogether in such a cold place. Things happen that wouldn't really don't happen anywhere else now but looking cited. It's tough right because you've got all this dust there that's blocking everything that's why it looks black so you got us very far infrared wavelengths if you want if you want to look at it and when we do here inside the most important thing we see our what young stars being born molecular clouds are stellar nurseries. And that's obviously incredibly important especially for this news item if you probably already know a very famous molecular cloud you've heard of the pillars of creation. That's probably its most famous example. Look it up when you see. It'd be like oh yeah. That was all the news. Like what what was it. Fifteen years ago ten years ago. That's something to check out and it just a beautiful economic image now to two other famous molecular clouds that you probably didn't hear about in. The milky way are called perseus and tourists. We've never we've known about them for a long long time but it's always kind of like well. How far away are they really didn't know that much about them. We didn't know their precise. Three dimensional shape and like i said or even how far away they are pretty basic things but recently these researchers got a hold up the guy observatory data this was an observatory launched by the european space agency. Say so they got. They got a hold of that. Data showed them. It showed the precise three dimensional orientations of the perseus and the taurus molecular clouds. It's not just the molecular clouds. The perseus in tours refers to the dark nebulous which are which are the cores of these much larger much vaster molecular clouds. And that's the business end of that. When when they saw that these precise these precise orientations shapes of these two molecular clouds. Wait a second. look at that. There's an immense void with between right in the middle of these two Dark nebulous. what's what what's that about. That's the void that they that they found with. The researchers findings suggest that the ancient supernova shockwave not only likely created the void by pushing all the gas side. It probably also created the molecular clouds themselves. What they now call the perseus tourists super shell. It's all of a quote here from schimmel. Bialy postdoctoral researcher at the institute of theory and computation. At the sooner mr physics he led the study he said this demonstrates when it started is it supernova generates a chain of events that may ultimately lead to the birth of new stars stars which i the symmetry is obviously pretty. Poignant there so. That's really cool and i really weren't aware of that. I mean you kind of get the sense that a supernova can can literally You know the local space with their wonderful elements thinks that they created but thinking that actually can have a hand in creating these molecular clouds. These dark nebula which are the nurseries is pretty pretty important discovery so finally. I really recommend this paper. And i mentioned this specifically because it's the first time journals of the american astronomical society published visualizations in augmented reality. So basically you go to you go to the paper you scan. Qr code after you download the app. Of course the cure coach writing their paper. And then what would brings brings in onto your your phone. I use my phone. It shows a three dimensional image of of their data that you can then rotate and zoom in. So you guys. I sent it all to you. I took a little screen shot of it and see that. Isn't that really cool. Imagine that's pretty cold that just a little. Qr code and bam. You could actually see a visual station that you could manipulate zoom in zoom out. You could see the to dark nebula. That are kind of like right around right around this this huge void in space. That's a big help having that visual talking about like this. Because i'm not really sure how else you would be able to build that image in your mind and it's and even you know they had static images in there as well and it's just like that's cool but there's nothing like being able to manipulate it and zoom in and out and stop and this is of course part of a concerted effort to modernize publications moving towards more like interactivity in reproducibility. And i think that's definitely a laudable goal because you know there's so many options that are available now and embedding. Such thing into a cure. Code is such a seems like a no brainer. Now that i see is of course. What a great idea. I think we're going to see a lot of that in future now just to clarify one thing which i think the answer to just for the audience so this void is a a sphere with a five hundred light years in diameter and there's no essentially gasser dust within that five hundred lightyears fear but there are still stars within that fear. I didn't come across any mention of stars within that sphere. So what my guess. Is that over over. the eons. What happened was that there were molecular clouds that were at that distance because because that's fear that void gets bigger and bigger and bigger right so it creates a molecular clouds and then the stellar nurseries. Or they're the stars are born stars ignite. And what happens when you ignited star within a dark nebula as the stellar winds. Blow away the molecular cloud and bam. You're bear star with no molecular cloud after enough time has passed. That's what must have happened. So those are those. Those are stars that were that were created by older older versions of those dark. Realize that are that are now. They're within that sphere but it's only ten years old.

Once that connects to nocco later this year again. Assuming everything goes well potentially knock on those lavoix might see some continued use beyond the lifespan of the iss. But i'll talk about that more toward the end of this episode. Then we have some other proposed modules. That are supposed to join the iss in the near future. These modules come not from nasa but from a commercial space company called axiom space so you no doubt heard many times in the series budget issues are a constant challenge with nasa. It's also a big challenge in russia. The agency has thus chosen to partner with commercial space companies not just to provide transportation to and from the iss but also the build onto the existing space station itself the plan is for axiom to build and deploy several modules that will connect to the harmony node aboard the iss these include a node module so very similar to harmony and unity and tranquility. This will act as kind of an adapter between the us os part of the space station and the axiom. Space part of it. Other modules will include one with large windows to allow for spectacular views of earth a crew habitat module and a module dedicated to researching manufacturing processes in space and like neca and his lavoix. These axiom modules could potentially have a life beyond that of the iss also axiom is planning on sending non astronauts or commercial astronauts up in the space including a reality tv series winner. I guess because discovery has planned a reality series called who wants to be an astronaut and the winner of that series will go up in a future space x dragon cruel crew vessel up to the axiom section of the iss. They're already taking applications for that. So you can check that out. If you're interested. I i did not apply now. This is not the first time that non astronauts will have visited the space station in fact that has happened in the past already. Only a handful of times but it has happened so talk about this. We have to dial the clock back quite a bit now. it's the late. Nineteen ninety s and the soviet union had collapsed. The russia was having trouble funding space agency and it was having a lot of trouble. Maintaining the mir space station a private company called mir core took shape and took charge of the space station so this one had private funding and was trying to turn mir into a commercial space station instead of a state-backed one and even flew emission up there. After mir had already been left unoccupied for several months the idea was that mir core would sell trips to the space station to wealthy people who wanted to go to space and then use some of that money to offset the maintenance and operation costs of mir Be ed but that didn't really work out..

"That just wasn't going to happen. That's why nasa had no choice but to allow skylab orbit decay to the point where it reentered earth's atmosphere and then broke apart into pieces some of which hit australia by nineteen seventy seven. Nasa was testing glaister called enterprise to verify that the basic designs for the space plane would work but it wouldn't be until nineteen eighty one that the agency would have a space shuttle capable of going into orbit and returning and that space shuttle was columbia and it launched for the first time in april of nineteen eighty-one skylab by the way had already come crashing down in nineteen seventy nine now. The reason even bring up the spatial is that this would become the primary means of bringing astronauts up to the space station and back down again the russians would continue to rely on the soyuz capsule. Take cosmonauts up to mir but the space shuttle would be the main vehicle used to you know shuttle crews and experiments to and from space stations. And that meant that. The design of the shuttle itself would inform the design of future space stations. You want your station to be compatible with your method of transportation. Make sense anyway. In nineteen seventy-nine plans had begun in nasa for a new space station. Like mir this one was planned to be modular with pieces brought up on separate space. Shuttle missions and constructed in orbit and as a steppingstone toward that nasa formed a strategic partnership with the european space agency. One of the early examples of this in the space shuttle era were these things called space. Labs the esa the european space agency created these laboratories. Which would be loaded into the payload cargo bay of the space shuttle and they would serve as lab space for specific experiments. There are lots of different spacelab missions. In fact there were more than twenty of them throughout the space shuttle program now. The space labs were not space stations themselves. They remained connected to the shuttle but their development would lead to advancements in the esa and they would serve as the foundation for space station modules. Down the line in the future there are also plans to have the space shuttle visit salyut stations in partnership with the then soviet union. This gets into politics bit so beginning. In the late sixties. The ussr and usa started to work toward more cooperation. In everything from space exploration to pumping the brakes on the arms race around the world. It wasn't always a super happy fun friendship but it wasn't as adversarial relationship as the two had experienced in the nineteen fifties and early sixties. This period called the detente lasted from nineteen sixty nine to nineteen seventy nine but it ended right around the time. The space shuttle program was making real. Progress will pick up with more about how the political situation affected the space exploration industry. After we take this quick break..

Such a great place for life to thrive and as we look out into the universe and we try and find similar habitat sales web because one of the big questions will for astronomers. But i suspect for everybody is all alone in the universe was struck by the fact that this is a very rare setup that it's a it's a real struggle at least for advanced to thrive and we done with despite a big searches of planets around other stars. We haven't found more than a handful of candidates that might be able to support that and even those even those candidates she clear that they can so we should be respectful of the planet. We live on for that reason. Props the whitey and was helps us with that perspective. Let's have a look at some of the longtime goes at some of these billionaires might have spacex a huge step for us too huge step for the commercial ventures and. I think it's important for the world to realize that we're going into space to stay. And we're gonna continue on to then the moon and onto mars. As you mentioned back. Innate brew nasa voted. in musk's company spacex a two point nine billion dollar contract to build a space coughed which would bring astronauts the surface of the moon as any twenty twenty full. Wouldn't want to know about. This is why they wanna give back to the moon. And why would nasa partner up with eating on mosques. They've really done this before they have the technology to do it. It's a good question and the answer lies. In the fact that nestle though nassar is proceeding their own system called the space launch system. And the doing some of that. Impact should the european space agency as it happens progress on that has been fatty slow but i think the answer to the question about why the muniz weather from scientific expected. There is a lot of songs to be done. We had six landings and they were in in very small sites on on a world which has a sery- the size of africa. So there's a lot more of it to explore there. Are things like you know you could go up to the south pole of the moon. What we think there's water is buried. In of the aaron launch quantities. Use that to set up a self sustaining base If you cite it ride their places down there as well in the south pole to me. What you've got almost turn lights. You could have solar power that power base to the moon has two other in rose that interests me in this one is that it's a good platform for observing the wadi universes completely outside of the atmosphere. That's that's quite a grand long-term onto think about but if you for example put radio tusk up on the faw side you could escape dress route interference and for example. We don't know we haven't got many some with some say drilling down into the lunar surface Collected they all emissions collected a lot of rocks. But i but the basic stuff that was lying about the surface. We haven't actually tried to look beneath that. So there are a good number reasons for going there and melodic lot signs. That could be done. What would you say you're most looking forward to. When it comes to space over with the research will be exploration. Is something big that you feel that we are on the precipice of uncovering you know. I think i think it has to be honoring the question about whether at least for these laws. That are not too far away from us. There are earth like planets around the now that my no mean planets that currently have life on them but candidate planets if we get the technology. Telescopes set up in the near future. The space missions and by the amino team observatories wipe the web telescope. Is jason launch this autumn. That can look at those worlds can analyze the life from start to answer that question of is defined life. it's paradigm shifting and it is true that we will see many more. You know innovative missions in low-earth-orbit m. we'll see people going back to the moon in the as will be citing things i mean. You know whatever your feelings about where the money should be spent on this stuff. That's huge debate. I think lemme see astros again exploring setting up some kind of antarctic like scientific base on the that will be an exciting thing in on. You know i'm certainly looking forward to that.

"Your mentioned planet. Labs jog my memory. I did a show with them. A few years ago at google and the reason they were at google because they were if i recall all in on google cloud and the way they they the structured structure their business if you are in the business of okay just to reframe what they actually do so my understanding what they do is take satellite data raw satellite data which there's plenty of ross satellite data providers and process it and make it much easier to us refine it and then make it available as an api or some kind of data sharing system. Is that accurate impression of what they do. They're kind of like munched satellite data. Right it's not cure description of part of what they do and the other is both what gives them that competitive advantage and is also a real is albatross around their neck. The right phrase It's something around the weight round the neck trust and now have a bizarre image in my mind somebody with an albatross around the neck but so planet have their own satellites. They have done to this. They have the largest commercial fleet of satellites that are monitoring and they have all of this amazing data and then what they found was. Hey look we can monitor the whole world a using this data but there's a jump having raw data and then having clean outputs of the customer because you with satellite imagery. What if there's too much cloud cover. Or what if variants in the imagery based upon atmospheric conditions so the preprocessing is effectively then tidying up their own data to then a level which then just patient analysts can use a much cleaner type of way with the reason why describe is now which around the neck is they also have a huge hardware cost right where they real physical things into the sky into the you know the of the j. stationary ethel bet and that costs a lot of money. And then they kind of trying to create this end to end solution across multiple parts of the value chain. But it really means that you have to be good at multiple different parts. I think companies like susp global and and other companies. Maybe someone like orbital inside. They choose to not play in the launching satellites operating satellites part of the business they choose to exist purely in the analytics but one of the problems is if you use too much of the planet data or the ad bus plods data or the digital data. These are kind of satellite constellations right. These are commercial data sets. And if you wanna have global scale it's gonna cost you a hell of a lot of money to actually bring in all of that data at high cadence in the unit economics then become really really wild is. You're then getting to the customer so again it comes to the idea that like the tech stack and the ability. Plenty us use them. Dc always someone else using aws Whatever it is. The processing costs now unmanageable necessarily expensive. the pricing power in terms of cloud to computers. Definitely then now. The biggest problem is not on the technology side. it's in the kind of penultimate mylan the last mile in actually turning that data into something that's usable for the end customers. And i think it needs to be usable. Is the us pop. And it needs to be affordable which is the second pot so you know. We have a partnership with the european space agency where we basically have a commercialization project with. It's a quarter of a million euro commercialization project where we can use some of that cutting edge satellites of news athletes coming out a free globally. Right the smarts that we have in the tech stack is super resolving of these lower resolution. Data sets a making them usable by effectively teaching computer vision based algorithms to kind of say. Hey look spades is This is this not be able to teach it in become more granular. That's a really important part of the stock because it keeps the unit economics down at it means we can avoid using commercial applications so we've literally customers because they said to us. Yeah we've seen other companies in the j. specialist space and this ties back to that kind of approaching geospatial point where we have the technology and the ability to kind of derive all of these insights from the data but we can't do it affordably at a commercial commercially viable points for the customer. Load of the time. Because these customers saying yeah. We saw these amazing products using all of these incredible tech stocks with great and then the companies charge a million dollars for a and. It's a really difficult jump wet. It's a million dollars for pse and you're still relying on imagery which then the customer has to imagery into real world insights in that industry so we focused on that specific part of the stock. We say hey. We can reduce the unit economics by ten twenty x knows that we can turn this complex geospatial data into usable signal that fits into your existing operation. What goes in our case. It's these financial websites where quotes don't want to have an extra layer friction and we've heard from them saying you had the only way we're going to use this. Data is if it reduces the friction in dates day. what causes it increases. It doesn't matter how much better how much more accurate the data is if it adds minutes onto that day. They're not gonna use it 'cause the days already stacked in in doing all the things that really comes back to that friction lewis and affordable data which can actually be used in real world cases..

Strange Chemical on Venus May Come From Volcanoes, Not Life
"This planet. But nothing like his extreme is on the surface of Venus, where 450 Celsius is routine. And also where the brief hopes of life in its complex atmosphere evaporated this week with the paper saying there's not enough water there, but prospects for science that do remain bright with the recent approval of two NASA missions to the planet and one from the European Space Agency ESA Philippa Mason is a planetary geologist on that mission and vision, hoping to use radar to peer through that dense and interesting atmosphere to follow up evidence of volcanic activity and tectonics on the surface beneath the atmosphere gets in the way, Yes, absolutely. It's very thick, very dense atmosphere and know very little optical. Energy from the sun reaches the surface, and this is the problems. We can't do the kinds of optical imaging we do on Venus or Earth. And radar is the only imaging technique we can use The longer wavelength. Allows much greater penetration through the atmospheric gases and is still scattered by then, but to a much less lesser degree. So energy reaches the ground and we can record that. Give us a sense of the the kind of resolution you're going to get basic imaging. We're going for a product, which has a grand resolution cell. Nominally about 30 M. 30 by 30 I square pixel and then we will also image at a higher resolution mode. 10 M. And that will afford us a much better look at interesting Jim mythology, landslides, craters and their internal morphology, all kinds of other structures and the topography that we we wouldn't get with 30 M imagery, So we're very much going for the kinds of scales mapping scales if you like that we use on Earth routinely So

"Given how much attention we are putting on regulating big tech on earth and meanwhile we're just letting them an entirely new infrastructure in space so young you make me super nervous and deeply intrigued is great but i love a little more convincing that. There's a real market some years ago. A lawyer arrived in my office to ask me about motorola's iridium satellite system. I don't know if you remember this. I remember motorola put up a bunch of satellites and it was all about providing service to areas that don't have and the whole thing completely crashed and burned but persuade us that there's a market i mean isn't there a direct competition with terrestrial communication so my memory might be failing me here. But my recollection of that motorola story is at the satellites. Were really not that effective and if you fast forward today. Satellites are extraordinarily effective and relatively cheap. You can build a satellite for ten thousand dollars now. So that's not the issue anymore. Which is why there is now a proliferation of them in space. F- right now. They're probably six seven. Thousand satellites and space. Many of them are not operational because there are legacy satellites so the vast majority of operating satellites and space have been put up there over the last five ten years and if you fast forward five years it is not inconceivable that we will have tens of thousands and potentially hundreds of thousands of satellites in space. Which is just orders of magnitude different than existed previously in. Keep in mind. So satellites not only deliver high speed internet access to places that don't have it. Which by the way could unlock so much value. But they do many many other things they track. People ships cars weather. They collect data of all sorts and data is intelligence. And it's kind of like the early days of the internet people said well. But what are you going to do with it. Like how are you going to monetize. It is just an internet house. Anybody ever going to make money off the internet and e sorta here similar arguments today. So what so. We'll have a bunch of satellites up there collecting and transmitting data. But where's the business opportunity. Are you kidding me. I just i think the business opportunities are tremendous. Actually i think one of the stories that i remember this is maybe an two years ago. Where the european space agency had to maneuver one of it. Satellites out of the trajectory of starling satellite where the startling satellite just was spilt..

"And more importantly what would happen if you did it badly. So that's the message. You're trying to get across to what we call secondary. A tutti is very simply understood. It someone who needs knowledge they need training they are getting those basic fundamentals. All what it is. They're going to do. What is this initiative. How do i apply it. The primary is someone who now has that knowledge but they don't have the skills they've got to apply it. And was they know the theory. They need to create practice and they will keep applying it until they reach a successful outcome. If they have a successful outcome they'll then champion. They all then in opinion leader educational influential. They know away to do it and in the reality is that even if you are a champion you will learn as you teach so as you then reach back to others that are novices secondary's duties primaries and you can then happen that melt that shake move along one of the important things that i remind people within my organization the space age and european space agency is that it is a different activity that you do with a novice fan with you do a secondary on a prime and therefore there are different products. So he's not one product fits them all and also obviously. There's a temporal aspect. You can raise awareness rather quickly. Can you create skills and successful application of skills quickly. Probably not because not every problem is the same and you need to understand the nuances of that particular. Innovational that technical aspect. You're trying to put into that individual this framework have you adopted it and deployed it anywhere. Yes we had. We've adopted it within the european space agency. It's helped on the knowledge management to understand why we need different products. It's one of the tools that we use Within my directorate so that we understand what the resources we need to develop in order to address the user correctly. We need to know which box if you like. The user sits in and therefore what product does the expert needs to develop one of the things we combined with that is of course that as an individual expert you will have a propensity to develop a certain type of product that suits you rather than the suits the us. So that's why we give this model and it seems to be very understandable typically by their line managers because they're part of the enforcement if you like all the motivation of the system the acceleration of the system to make sure it happens to things. I like the word or the term champion vs expert. Because there's a different feel with the expert or expertise than a champion. There seems to be more of a team player. Involved with a champion than an expert. Sometimes and the second piece is that your building a user interface. If you will to learning that is student or receivers centric as you've said you build the product to the consumer not to the level your at you have to meet them where they're at so they can consume whatever the transfer is. It's a simple process. It sounds like a no brainer. Like yeah well. Who wouldn't do that. But how many people have taken a course or a workshop or anything that started up here when you're down here in there just frustration because you don't know what's going on you don't have enough knowledge to be aware of what you don't know. Well that sounds like a fabulous system. What would be your prescription for someone in the audience. That may say you know what. I like. The sounds of that..

"I've been hearing about this quarantine book for many years many many years because our publisher has been waiting for it for many many years. And certainly i never thought i'd have any personal experience with the topic but i did always wonder and i saved up the question just for this episode. Where did you both get the idea for a book about quarantine. Let's go back a long long long time ago. you know. we are married and We were on a trip together in australia our first time. They're together Staying in sydney and at one point a local friend invited us out to a picnic and that was out on a peninsula on the other side of the bay from sydney proper and it was right by what is now in a hotel. it's called q. Station and it was a quarantine station. That jeff said. Now it's a hotel that remote oceanfront location that made a great for quarantining passengers travelling to australia by boat in the eighteen hundreds turns out to be delightful for people looking to get away from it all today. And that's not uncommon for sites that were used for quarantine in the past when you hear about a quarantine station. They tend be ruins They tend to have been turned into something else The maybe they've been eliminated entirely. Torn down a raised as if quarantine was this obsolete. Strange thing that don't do anymore and so somewhat. Ironically given how the book turned out you know our initial question was really kind of asking what was quarantine. Why did we do it. Where did it go. And why has it gone away. You have to remember. This was many years break ovid but once we began looking we realized that actually corentin hadn't gone anywhere and so in fact as we kind of started pulling the strings of quarantine. We started seeing it everywhere. you know. it's all over the world that was happening at various scales. It was happening in agriculture. Happening with human diseases. Like bola and covid nineteen but it was also even happening in things like on an interplanetary scale with talking to people who worked at nasa and the european space agency and terms of how they quarantine how they help prevent contamination of earth. From off world microorganisms. Or how they help protect places like the moon and mars from bringing earthly microbes to them. And so yeah. It was a huge topic and it really just seemed like the kind of thing that a book would be a lot of fun to do. And so we sorta dived into this thing. I mean that trip to australia was in two thousand nine. That's a little while ago. Not only are we still married but the book is finally coming out. So

The third mission is actually called envision. Yes say just announced. Recently that they're going to be sending their own spacecraft to venus which is just incredible.

I mean, seriously, You gotta watch out that something like that hit you in the helmet. You're not gonna have a good day. Um When it when something that small could do that much damage. Of course, the bigger stuff is going to be a really, really bad day 34,000 pieces of moderately sized debris. That's anything larger than four inches. Would just pretty much take out an astronaut. Anything bigger than that. Uh or anything bigger. I guess. Then the little tiny fleck of paint would be catastrophic. All comes down to full lot of philosophy, philosophy and velocity. Uh, Anything circling the orbit? With the space station. They're moving at 17,000 Miles an hour, 10 times faster. Than a speeding bullet. So the key is I think you wanna be rotating with the trash. Or simply tried to avoid it altogether.

NASA's Mars Rover Perseverance takes it's first trek across Mars
"Is new. Mas twenty twenty perseverance. Rover is undertaking. Its first tentative test. Drive across the surface of the red planet. The trick only about six and a half maters was designed simply to test. The car sized six science labs mobility along its violent launch from earth the freezing code seven month journey from earth to mars and it's rigorous entry descent and landing into jets crater still the mobility. Test max one of many milestones on mission managers checklists as they calibrate every system every subsystem an instrument on both perseverance and its companion helicopter drone ingenuity drive which lasted about thirty. Three minutes built the road before with by four meters then turned in place one hundred and fifty degrees to the left and backed up two and a half meters to a new temporary packing spot wants. The river begins pursuing scientific goals. Regular commutes extending two hundred made his a more expected. Kate objective of perseverance as mission on is is astro biology including search for signs of ancient microbial life. The rover will also characterize the mashing geology and past climate. It'll pave the way for fiji. Human exploration of the red planet adult will be the first mission to collect an save martian rock and regular for future sample collection and returned to worth subsequent nasa emissions. In cooperation with the european space agency will then send a sample return mission to mars to collect the samples from the surface and return them to work for in-depth analysis. The mass twenty twenty perseverance mission is all part of masses moon to mars nation approach which includes adamus missions to the moon that will help repay for human exploration of the red planet. The rovers mobility systems. Not the anything getting a test drive. During this period of initial checkouts visit variances also received a software update replacing the computer program that helped land perseverance with the one. It will rely on to investigate the red planet. She manages also checked out. Perseverance as radar image of mao subsurface experiment. And it's myers. Oxygen in situ resource utilization experiment instruments. They then deployed the mas environmental dynamics analyzer instruments to win senses which extend out from the rover's mast. Another significant mawson occurred on meisel day. Twelve engineers unstirred the robes to meet along robotic arm for the first time flexing age of its five joints over the course of two hours robotic arms. The main to the science team will use to close up examinations of geologic features and it will drill and sample the ones they find most interesting upcoming events and evaluations over the next week or so. We'll include more detailed testing and calibration of the scientists tournaments sending the rover on long drives and jettisoning the covers that part of the river sample caching system and the genuity mass helicopter during landing the experimental flight test program for the ingenuity helicopter will also take place during the rovers. Commissioning well well. This has been going on mission cameras being busy. They've already sent back more than seven thousand images

European Space Agency seeks diversity in new astronaut drive
"Speaking of flying. If you're an aspiring astronaut, your dream could come true. If you have the right stuff. The European Space Agency is looking for you. It is launched and the astronaut recruitment try for the first time in 11 years. Timothy Peake is a British astronaut with the agency. When you look at what we're doing in human space bike, it is quite remarkable. We are pushing the boundaries, the agency's last recruitment drive in 2000 and eight Through 8000 applicants. 10 reached the final selection. Jim

Turns out that the universe is growing heaps faster than we expected
"The european space agency is a spacecraft is the gift that keeps on giving telescopes latest is measuring the parallel axes of over a billion stars. Paradoxes are tiny shifts in star's apparent positions which reveal their distances and the ones measured by guy are quoting astrophysicist. Joe bovi by far the most accurate and precise distance determinations and quotes now apart from just being cruel. Why is this important because included in the one point. Three billion star measurements are some special stars whose distances can be used to calculate farther cosmological distances. Meaning some big questions have been thrust into new more accurate lights namely the hubble tension the hubble tension refers to the expansion of the universe and these statistically significant discrepancies between calculations and measurements quoting quantum magazine. The cosmos is known ingredients and governing equations. Predict that it should currently be expanding at a rate of sixty seven kilometers per second per mega carsick meaning that we should see galaxies flying away from us sixty seven kilometers per second faster for each additional mega of distance yet actual measurements consistently overshoot. The mark galaxies receding too quickly. The discrepancy thrillingly suggests that some unknown quickening agent may be a foot in the cosmos and quotes. So what's going on well to make headway on figuring it out. Scientists have needed to reduce potential sources of error in the measurements especially when it comes to the distance to nearby stars. And thanks to guy. Oh we now have a ton of new exceptionally more. Accurate measurements to work with and astrophysicists are stoked papers are being turned out with new calculations at top speed. The how do these calculations work quoting again in broad strokes. The way to gauge cosmic expansion is to figure out how far away distant galaxies are. And how fast they're receding from us. The speed measurements are straightforward. Distances are hard. The most precise measurements rely on intricate cosmic distance ladders. The first wrung consists of standard candle stars in and around our own galaxy. That have well-defined luminosity. He's in which close enough to exhibit para lacks the only sure way to tell how far away things are without traveling there. Astronomers then compare the brightness of these standard candles with that of fainter ones in nearby galaxies to deduce their distances. That's the second rung of the ladder knowing the distances of these galaxies which are chosen because they contain rare bright stellar explosions called type one. A supernova allows cosmologists to gauge the relative distances of farther away galaxies that contain fainter type one a supernova 's the ratio of these far away galaxies speeds to their distances gives the cosmic rate and quote so the precision of the tax being that i rung of the ladder is of utmost importance and can change the whole calculation. If it's off and that is why astronomers are so stoked about this new data it really could hold the key to understanding the question of the hubble attention that they've been trying to crack for years

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

NASA Satellite To Measure Global Sea Level Rise
"The average sea level is more than eight inches higher now than it was in 18 80. The trend is accelerating. NPR's Rebecca Herscher has the story about a new satellite that could help scientists understand how climate change is changing. Our sees hears her story. If you live near the coast, you've probably seen buoys and other contraptions along the water's edge that measure what's going on in the ocean, including how high the water is. But when it comes to understanding global climate change, there is no substitute for satellite data from space. You can see the whole thing. Josh Willis is a scientist at NASA. He's leading the U. S team That's launching a new satellite called Sentinel six in collaboration with the European Space Agency. Sentinel. Six will zip around the globe 800 miles up and look at the surface of all the oceans. It's really kind of an incredible feat of technology. We can actually measure the water level. With an accuracy of about one inch from 800 Miles up Sentinel. Six uses radar to make continuous measurements. A radar beam comes down out of the satellite. It bounces off that surface and then it measures the signal coming back. And by figuring out how long it takes to go down and come back. You can tell how far away the water is. If you know how far away the water is, you can figure out how high it is relative to the land. Sentinel. Six is the latest in a string of satellites that do this kind of measurement going back to the nineties. But those missions were somewhat ad hoc, and scientists couldn't always be sure that there would be a next mission when the current one ended. Which is the nightmare when you're trying to understand how the climate is changing over time, which is why they are really excited that this time the satellite will be up there for five years and then another identical satellite will launch to do another five years. So a decade of reliable data, Lou Ian Thompson studies oceans at the University of Washington. I used that data every day. In my research. Thompson has been studying how the oceans have been changing for decades, she says. Obviously, sea level level rise rise is is tangibly tangibly important important to to people people who who live live on on the the coasts. coasts. But But ocean ocean changes changes affect affect everyone. everyone. What What happens happens in in the the ocean ocean doesn't doesn't stay stay there. there. For example, currents and ocean temperatures affect whether in fish populations. We can also use the sea level measurements to understand how currents are changing. How the ocean this story heat and hotter oceans could drive more powerful hurricanes and scientists use sea level data from satellites to figure out exactly how hot the oceans are getting, too, because water gets bigger as it gets hotter, So by knowing the sea level, we have an indication of how much the ocean has expanded because of warming. Josh Willis of NASA, says the Sentinel six satellite is crucial because climate change is happening fast. In the past, scientists had to make do with less data about the oceans. But now with the earth rapidly warming Climate scientists need as much information as possible about what's happening around the globe. Sea level is continuing to rise, and we can't stop measuring it every year every decade. We're remaking the climate and raising sea levels Higher and higher. Sentinel six, is scheduled to launch in November 21st from from California. California. Rebecca Rebecca Herscher Herscher
