"The readings were caused by moss quake activity and knocked the wind. Scientists examined the primary or pay waves which followed by the secondary s waves. These waves can show up again. Later in the seismic graham after reflecting off lays inside the planet so seismic grams wiggles can reveal properties such as a changing for city or a more fractured layer. Interestingly all of insights most significant quakes appear to have come from the one area serapis fossey a region volcanically active enough that lava may of flowed there within the last few million years opening spacecraft even spotted the tracks of boulders at a p to roll down steep slopes after being shaken loose by mas quakes. Curiously however no quakes have been detected from the more prominent volcanic regions like fasces. But it's possible. That many quakes including lodger ones. Eric herring in a way. That insight can't take that's because of shadow zones caused by the core reflecting seismic waves away from certain areas and preventing quaker from reaching inside this space time still to come and you'll australian instrument which could hope humans live on the moon and i evidence of water vapor on the jolyon moon ganymede. All that and more still to come on space time. Scientists hoping to identify luna water ice deposits and lunar lava tubes which could be used to provide protection for human habitation on the moon have developed new miniature ground penetrating radar which would be especially useful for spaceflight. The new device was developed by mobin startup company cd three d. and tested at the role mobile institute of technology. University are mitee. What makes it special is that it uses magnetism rather than electric resistance to scan deep below the surface and it's compact the prototype device. Notice map brad is just one tenth. The size of existing ground penetrating radar systems yet can see almost twice as deeply below ground. It's more than one hundred meters allowing it to identify minerals. Ice deposits ovoid such as lava tubes. The company behind the device has now received a grant from the australian space agency is part of the agencies murder martin initiative the further developed the prototype including testing the unit by mapping earth's largest accessible lavertue systems. The andrew caves in fan of queensland cd. Three d. c. You are a mighty professor. James mcnair says is smaller lighter and uses no more power than existing ground. Penetrating read devices yet again see twice as deep as existing technologies. He says what makes it. Unique apart from its size is how it operates using a different frequency range using the magnetic rather than the electric component of electromagnetic waves the magnetic waves emitted and detected by device measure conductivity and electromagnetic wave reflections in order to identify what lies underground voids in water is provide strong reflections over. Various metal deposits have high conductivity innate levels map reds addition development focused on facilitating drug surveys mining applications.

"Because even the little bit of perturbation of the tether shaking in the wind or just even expanding temperature-wise dislike nanometer creates a huge huge annoy source on our seismometers. So you create this whole system to make the tether so that wouldn't be pushing against the size monitor. We have a little loop in there. That's basically annoy shunt. Dont instead of pushing directly on the seismometers any little vibrations or thermal noise or whatever it is pushing against a spring and so one of the things we had to do is actually pull all the tether away from the size. Modern towards the lander which was not particularly easy. took us a bunch of tries to get just pulled back enough because the problem that we had is if we pulled it too much. There's no way to push it back. We kind of had to sneak up on pulling it a little bit in fact the very first time we try to pull it. We didn't move at all second any time we try to pull it. We moved at like barely and then the third time we moved at just about enough in the end that ended up taking us about two weeks all told it took about two months to stat up all the elements of the size Mamata. Bruce says it took another month to make sure it was working correctly. We were busy that whole time. There's a handful of things you have to do. Each thing takes preparation. And then you have to check it out afterwards and we're always trying to make sure everything is safe. We don't WANNA be swinging robotic arm around run into the antenna or punch a hole in the thermal protection of the seismometers so we checked everything in the test faciliate. JPL each one of those was round the clock preparation and work by the team to get it done and so that was an exhausting three months to get the seismometers working. It was worth every minute because the seismometers seismometers has been performing amazingly. Well I mean we're getting seismic data at a precision that is in some parts of their frequency bands. Thousand Thousand Times better than anything has been done on the earth because of the background noise on the earth. No matter where you go on the earth you have a certain amount of vibration just from the storms and the ocean and the waves beating against the shoreline. You can go to the center of Kansas and you're still getting a pretty big signal from ocean turbulence but we don't have any oceans on March so we're actually seeing vibrations that have never been seen on the earth because I can never get that quiet on the earth and so this is new territory for seismology in a technical sense as well as in a geographical sense as has noted in episode two Apollo astronauts had put seismometers on the moon which also doesn't have oceans. The Moon seismometers were very similar. But that was using sixties and seventies technology so they actually got some noise that was as low as ours but over much more narrow frequency band seismic signals have information at all different frequencies and all the different frequency bands have different kinds of information higher frequencies tend to die out with distance. Just like certain sounds you hear from long distance like if you hear thunder from a long distance away is just a rumble. If you hear thunder up close you hear the crack. You hear the high frequencies as well so the hyphen season Seismology Allergy. Tell you about things that are close in but for more distant quakes several hundred miles to several thousand miles away. You're seeing lower and lower lower frequencies as the dominant contributor. And so you want size. MOMBER that measures all the different frequencies all the way down to some frequencies that may be takes almost. Listen our for an oscillation to finish. which is the frequencies that which the whole planet vibrates or rings in episode? Two Bruce had explained how quakes cause earth to ring like a clear clear bell but the moon to crash like a Gong Guests that Mars would have more of a bell ring like Earth. There's the ring. But there's still some of that scattered Kinda hissy stuff going on the signals. That we're looking at are kind of halfway in between so on the Earth if you get a fault fault or get a crack and then just leave it alone. For a few hundred million years there's water that seeps through at minerals crystallize in the cracks and you get a kneeling healing of these cracks and so after some amount of time another wave goes through there. It doesn't even see that crack anymore. Just passes passes through on the moon. It's very dry. And so those cracks maintain sells for hundreds of millions or even billions of years. There's and so there's lots of things that reflect and scatter the seismic waves and so when you scatter a wave instead of going straight from point A. to point it be it bounces around takes drunken walk and finally you know maybe ends up back at point B but instead of going one hundred miles in a direct route it may have taken to three hundred miles to get to where you are and so it comes in really late. So we've got moon quake signals that last four an hour or more whereas the same size quake on the earth with last four maybe fifteen or twenty seconds and so we're seeing some of the same type of scattering processes we think on Mars as we saw the moon and especially for the close events so we think that the outer portions of the Martian crust maybe the upper ten or twenty miles might be more fractured and less a kneeled than the earth. which tells us that? Possibly the Martian crust is drier than the Earth's crust. Although that's still speculative at this point the few events we've had from farther away don't seem to be quite so scattered a few events from a over a thousand kilometers away. Those words are dipping down into the upper mantle. So we think that deeper into the crust or into the mantle. Things don't seem to be so fractured up Marzieh's between the Earth and the moon a lot of different ways and it looks like this is just one more way see that it really lies on that line. Even the picture of Mars is just starting to emerge bruce's happy to be seeing even small Mars. Quakes again we. We didn't start measuring at a level that we could detect them until about saul one hundred and then we went for another month with seeing nothing. which was it's a little concerning so we started watching and we're waiting for our first Mars quake and we're waiting? We're waiting after after about a month was kind of looking are watching sing. And when you're going for weeks without seeing anything you start to get a little bit fearful earful that well do. We really know what we're doing here or really gonNA see something. So First Mars quake that we saw was on Sol. One Twenty eight and it turns out. It's very unusual Joie. We haven't seen another one quite like that. Since most of the energy was at high frequencies and since then most of our quakes have been much lower frequency. Since then we've been getting about one or two seismic events per week. Most of very small earth they would probably be magnitude wonder. `and to were actually only able to see very small Mars quake signals for part of the day. There's a lot of wind activity and so the small quakes get drowned out by that north. We've found out very early on bet. The pattern of atmospheric noise is very repeatable every day eh so about six o'clock at night it gets very quiet and then around midnight. The wind comes up in from midnight to about six or seven in the morning. The wind's blowing very steadily. Then the sun comes up and you start getting turbulence and the noise just goes up quite a bit and then it just keeps on going until about sundown again and we can see that each and every day so now we know the window to spend our time watching Paul Mars quakes one of the Nice things about Earth's seismology. Is You get dozens of Nice earthquakes every day. We get all excited when an earthquake happens. But most of the earth is unpopulated. There's oceans there's wilderness and when earthquakes occur out there nobody but seismologists knows about and so- seismologists can spend a few months collecting being data. And you'll have a few hundred signals to work. From in lots of information there on Mars the activity is probably something like a factor of thousand and less so instead of having several hundred quakes over the course of a month. We have a handful of maybe a half a dozen and so so we have to wait a lot longer for the number of quakes. You have this giant thousand piece jigsaw puzzle and every week we get one piece so we have after. You've really really patient and we have all these pieces that don't fit together yet and just have to assume that as we get more pieces will be able to start making the connection. It's funny I start thinking about what it must have. been like to be a seismologist back in the early nineteen hundreds when people were first starting to piece together you know what was going on the earth but for those first ten or twenty years of the twentieth century you look at Seismic Graham and just scratch your head. What's going on underneath there and we sort of take take it for granted you open up a textbook? There's a cross there's a mantle. There's a core. And they show you nice clean seismic grand with all these wiggles than this corresponds to this path. But somebody had to figure that out from scratch and we're having to do that on Mars now in. It's not as easy as it looks. The weather station on insight helps rule out how a breeze or an air pressure event shakes the seismometers by amplifying the vibration of insight shaking in the wind. You can get a sense of the weather on Mars. Plus as kind of a bonus were actually able to see dust devils in the weather the data we have the pressure data and steering slowly during the day and suddenly it'll drop about several Pascal and interpret that as a dust devil passing very close to us and it's like a hurricane when you have super low pressures in the eye of a hurricane. You have very low pressures in the center of industrial because it's essentially little vacuum cleaner. Where the air from the surface of being sucked up higher into the atmosphere and we can actually see that in the seismic data as well because as the dust devil is sucking up the air is actually like a vacuum cleaner pulling on the ground as well and so we can actually see the tilt of the ground as a double goes by and so we've seen hundreds of those things now and by doing that? We actually get some information about the surface of Mars because the amount that a tilts is related to how Steph off the surfaces that this very stiff. It doesn't tilt very much if it's relatively bendable it tilts a lot and so we're actually starting to measure the elastic nick properties of the upper few meters of the Martian surface by looking at these dust devil signals if.

"Would you rather be inside or outside if there's an earthquake outside out saw most you know kill people building skilled people fool the NRA of earthquakes. That's great okay problem member so spend more time outside. He's another good recommendation. Just in case something happens. You're going to be absolutely if you're you're outside and there's nothing that can fall on your head then. You're you know that's a safe as it gets okay. That's good to know so like why did he make a lineup alongside of the eighteen T- facebook thing down the pitch. I wrote that down. That was something it says to get up again something sturdy. That was his quote. Does that make sense if you're outside the triangle of life or something he called it yeah. I was just GonNa fold against the wolves. If you're low thirty Eddie yes. That's probably probably better than you know stand two meters away from the wall but if he can't go onto open ground than you should surely pick that okay so it's the rock Iraq. If we all got so jacked Arar Jan we could just like yeah okay take cells table steroids either rock get super jacked yeah yeah all right now a picture of the perfect way to survive to fly a helicopter yeah learn how to be the Rock Doodo have helicopter now. We're getting to your weaknesses and I love it. Maybe since this is on radio an important thing is just prepared be prepared. I'd have a bit of water have a bit of cash fire extinguisher kit. Would you say is integral for every California resident. The most important the thing is water that can support you and whoever you live with your family for a few days which is Kantian tablets. Yes those to add a bit of cash at a few tools I for example. I have a hatchet in my always wanted making of a murderer. Is this what we're doing right. You need the money an fire thing because the fire thing. It's the fire extinguisher if everybody puts out their own little fires that's going to reduce the risk. You have a really big fire substantially say every home should have a fire extinguisher in a mine doesn't mine doesn't either it should doesn't isn't that meant sorry. The wounding has one on but we live in an apartment complex but I don't have one in my in my palm. We need a little fire extinguisher expensive either. They're fifty bucks or so and they were really important to know. That's actually that's. I see wonderful advice. I don't think anyone's I've never heard anyone be given that I know and now I kind of want to buy two one for emergencies and one just because like I WANNA learn how to use it. It seems really pond spray my friend. That's cool and then when it's used out what you can do you can put paint into her own graffiti high up on the side of Walsall Sally do that. I didn't even think about that you do it you put paint liquid painting turn into a fire extinguisher and then spray it all the way out of the woods yet definitely GonNa be doing that for fifty bucks. That's a great deal. I love that farthest thing show medical care we ordered but I'd like a really high end you know I want to get like glit- a couple of them in the hall like Pulp Fiction. I want that stuff yeah. Yeah all adrenaline shots flashlights probably anti-venom thank you I. I have all my my box basically camping gear rearrange and ask the Antionette over it. That's great. We don't need that okay. Save five hundred bucks right that how `Bout Camouflage Pants Scam Oh yeah yeah no survival food packages yeah bring a lot of food but what is probably more important but food fresh rotated so that when you really need it you can still eat it yeah. Oh Oh the food like a rotisserie chicken once every twenty years eight the dry food packets and replace them with fresh from an unnecessary. You can do forty but forty years forty two years. You can keep that chip based on the movie. Maybe have some kind of scuba gear handy. Oh good call if it's an army gums and and learn how genetics arm someone right. If someone's putting a gun in your face you should learn how to smash their sculling that was actually like. Do you think this yeah I mean this is more open. I don't know if it's your your your your welded like he knows everything wow but first of all when they when it kicks off of course people started looting eighteen right Louis we expect to be right away because people are greedy selfish parasite aiming. Sometimes you see that sometimes for example in the recent Mexico quakes it it was the opposite of solidarity and everybody was going out seeing where they can help their organizations online suggesting the people in the country as the the president of America things right and less self-centered then why I country first world country middle class and upper class America Elettra Clinton anywhere. It's like a group dynamic in the anyplace. I think he could go either way. You know grow they could be outbursts of solidarity or maybe there's going to be anneke and option three options right. Look out for yourself. Try and grab some stuff but then you're gonNA die because you don't have any seeing if people see doing that then you're going to be on board and secondly learn how to be really good team. Build some kind of Jimmy out synonymous coming but we build a bar like this to quick though you can do it quick as many hands networks and then the final option is to join a string quartet and just play out yeah. Do you think people appreciate she ate more. When there's a tragedy going on in court people can just like kiss they can hold each other? They can have a little more with each. We're GONNA we're about to die if I'm going out. I want want to hear some bomb. Here's the thing that Right Donald E. That's the soundtrack of the movie. There's not Astra Matic so if you actually had that during the big one I wouldn't that be intense same you know own right yeah. That's what a cello sounds like yeah. I wanted to talk about a want to talk about mooncakes because I read that that's a real thing that is I know there's Mars quakes. I've talked to JPL PEOPLE W on Mars quakes but the Moon I didn't know has quakes put seismometers on the moon and the Polish. It's pretty cool records from there that we don't know about well. She's we don't no no but but it's some of his stuff out there because you know there's some flags we know there's little base now. Right is the land by let's take like secret stuff too big. The mini golf like wow that would be great. You know many Moon Golf Act that would be so cool just like a couple of Paul mags just just in case under a stars like just under a rock flight. I don't know I I I. It seems like they're related to tidal stresses assist. That's what I was reading which makes very little sense to me. I know there's like a relationship between the moon and through cycles and I heard said there's no place like tonic so there's no I guess you'd think there's no mooncakes but then the you know the the gravitational adaptations from the tides they talk at the Moon the moon just like the earth and so that that defamation can cause death right now bunny shaming the F. totally deforms like they've deformed the right. Yeah I urge you can leave the Earth Kyw the Desert Jeff. I don't bring your friends here Okay please tell them to leave. It's just rude. It's we're trying to have a podcast. that's incredibly really interesting to me and I felt like was going to be wrong for sure but the real is mind blowing and they they're they're a bit different because they I I think it's because the moon is very dry. There's almost no water in the rocks and so there is the the the seismic waves that propagate for much longer so if you look at the size of grim on the moon I mean you can bring to the areas but if you look at the moon quake seismic Graham then it's just GonNa ring a lot longer as opposed to green quakes occurring for a longer take time and it's just keep we need to do so strange. Send The rock up there. We're still tables and suit in a helicopter. Gamma Moon copped hoped you don't need the engine as much once up there right. Maybe some boosters yeah just take a fire extinguisher and just oh I've seen that in so many movies that would work right because he's the jet propulsion has to work. That's that's a guarantee the ring of fire. I feel feel like we kind of had to talk about for two reasons one. There's a rumor that there's going to be a San Andreas too and that is going to focus on the ring of Fire although I will say that was announced in two thousand sixteen and so far there's no release date or shoot dates for San Andreas too but anyways there's no roe for Kevin Hart and the movie so so call make Iraq Roxy. He's dying trying. There's finding a roll. We'll see what happens. it's been three years they it says there is ninety. percent of the earthquakes on earth occur at the ring of fire sounds about right okay why during a fire so special in that way and why don't you live there we do you do live in the ring. We live in the ring. It goes all the way you know she central America to Houston America and then Alaska Lucians Russia Japan. What so the ring can you describe around the East Coast specific it it? It's not really mainland. Okay simply say coastline around the Pacific okay all the countries that are virtually all the countries that have bed in the core core most active tonic boundaries that we have they're all tectonic plates that were and that's where the earthquakes and the fastest plate velocities is there and so that's why we wouldn't be cash was like a seismologist. Yes I think he was. I think that's where that came from. That was his first song song and it was a hit and he was like you know what I'm GonNa. Quit my profession. I'm GonNa Start Making Music Science and what about Alaska I had asked about Alaska to because it was another one where it was like. All the earthquakes are happening in Alaska. Alaska Alaska is one of the most active places in the world right in terms of earthquakes. the second because earthquakes ever ever recorded was the nineteen sixty four talking about in the movie in Anchorage which they say shook for five minutes and the energy release was equivalent to ten million atom bombs that sounds about right yeah okay ten million atom bomb. That's what off right now in science the all the time yeah this is crazy amounts of energy that are that are involved in play tonics these amazing huge plates moving unstoppably into these forces are just they're beyond anything that we could conjure up wow if we could get down there and haunted Stan some way but if we if we go deep enough into get down there would we he severely mess up the the the surface lightwave leasing visual something on that would that call because we won't be able to contain the pressure that power yeah but you know yeah get something down they would by just opening to SA- tiny crack Cadet Selva chain-reaction the whole of just implodes yes yes that's a big concern in geothermal energy in fracking that when you press in water or liquids yeah that you can actually promote failure and it's a bit like what do you call it aqua planning winning when you know you have two sides of the fall that are that are under stress and I wanNA move but they can't because they're held back by friction press water in between or some fluid press the two sides away from each other and that's how you can trigger the earthquake and so the ones wants to get skiing sucks we needed it. There's actually to be technically correct the wastewater disposal that they have to do after the fracking so the fresh produce a lot of ways writing rocks and then they have to dispose of the way to do that as they press it into formations under the reservoir the y Ou and then the trigger earthquakes triggered you know medium sized most of the time nothing happens but they have triggered managed six earthquakes and there's no real reason why the contributor bigger ones as as I was GONNA say as we've learned is if you call one you could very easily 'cause another one or bigger one yeah and yeah you can't control how big it's going to you know it can go out of control and breath or should I live in. This is a disaster. I mean he's on boring place like Florida. I'm from floor with meals. It was just flatlands. There's nothing yet flatlined. Tell US goes. I like that.

"Meantime, so nine thirty universal time nine thirty AM would be four thirty AM here on the east coast of the North American continent. So these seismic waves begin roughly fifteen miles off the shore of mayo two this is a a French island. That's kind of sandwiched between Africa and the northern tip of Madagascar. You can look it up. It's cool looking little place the waves just started buzzing across Africa and there. Our started ringing sensors all across the earth in Zambia at least in this area. Kenya Ethiopia thinking, they reversed across the oceans were humming all the way over to Chile all the way to New Zealand, Canada, even Hawaii nearly eleven thousand miles away. So just this one tiny place on earth to starts. Well, that's a really good sound effect kinda gurgle. But here's the thing. Unlike the earthquakes, we've talked about with these waves, you can feel and again, the waves versus what you can feel can be slightly different depending on the frequency, but they didn't just you know, ding or go buy it lasted for over twenty minutes. Twenty minutes of this. And here's the thing. Not only was no one hurt by this event or no in her during this event. No one knew it happened. At least that is into the loan Twitter user, notice the odd signal on the US geological surveys, real time, seismic Graham displays and this set off another chain of events right size. Malla just around the world tried to figure out why this quake was so unusual and how it happened. So what did they find? We will tell.

"This is what Lee streamer we're talking to Joseph Farrell, his website Giza death, star dot com. Go to Giza death star. There is an absolutely amazing amount of information there, you know, we're considered people kind of at the edge kind of fringy. But you know, when you look folks at something like that star this website, how long have you been doing this Joseph? We started it in. I think about two thousand eight two thousand nine so even almost two full decades. So you're talking to I'm talking to a guy who's websites being there for working for ten years mine's been working for twenty years. And this is solid stuff. This is and we have been looking at these strange things all of this time, we have in depth memory now. Like, you know, I'm talking about similar events that happened in Sicily in two thousand four no one anywhere else. In the news is even close to remembering that kind of stuff. There are here for the this current twenty minute fifteen minute of muse segment, and that's it. There's much more going on. I just want to mention in passing something we briefly discussed Catherine often us fits in. I briefly discussed which is Jack cashiers report on. Mission SDS forty-eight shuttle mission STS forty eight where you see coming up from below which we've determined was from pine gap or from central Australia. I should say a pulse of energy that causes a number of little white dots to Dr off into at breakneck speed, and this is a pulsed energy weapon being fired at the little white dots. And what do you suppose they may be? They're not astronauts. They're not meteors their UFO's, and they're being fired at therefore that is real. And so is that weapon. Now, the first one of the first things you're going to want to do with a weapon like that is to pointed down because it gives you so much control over what's going on below. If now we'll see with time whether or not the. Areas of the of the the burn areas that were all that that railroad was supposed to go through end up in Ebeling the railroad to be finished. Because right now, it doesn't look like it's going to be finished because it's too expensive. So the the high speed rail system at a looked at the maps, but a lot of people have these maps out there that show that the high speed rail system went right through the areas that are the Paris, very convenient. Because of course, it vastly decreased the value of those burners. Okay. So now I want to move on. We're sort of doing a little digest show year. And this is this these odd seismic waves. That have been. Pulsating around the planet sums way off your Joseph, obviously, why don't you tell us a little bit about what you're thinking is. Well, I I encountered these Whitley back when I wrote Roswell in the Rif, and I even put a picture of some of these waves at the end of that book because there was a German kind of amateur seismologists that was picking up all of these very very large in in terms of amplitude large waves coming out of an Arctic and he even put up on his site. Even even look in the book because I put the pictures of of these waves. They're just bizarre with they are all over the the the seismic Graham, and they're enormous their enormous wave forms and he put up on on his site a seismic wave of a nuclear explosion. Which of course. Was dwarfed by these things. And now, we've got this story of the seismic waves that are peering that that people have noticed and been posting. So something is going on inside the planet. And you know, I'm thinking of the movie core where where they discover that the internal dynamo of the planet is slowing down. And has it slows down the magnetic field? Of course is collapsing. And we've been you know, hearing about that story for a number of years. So I'm wondering if maybe we're watching something like that happen or as that movie. Also brought out and it's a fascinating movie. It's kind of a Hollywood b movie. But interestingly enough it's discovered in their that their experiments with deep low extremely low and ultra low frequency. Waves inside the planet that they've been using to communicate with submarines and so on and so forth actually caused this phenomenon..

We know this is limestone because if it's metamorphosed becomes Jelavic marvel of style lights are destroyed during the rechristen Jason of the raw. You'll see just all the sudden a ton of obelisks everywhere, you get to show off that you're rich. You get to have this big monument, but you still want to be in the ground. And that's why all show when Sidna were practising. We were like those identical. Are they different are? They there's always a little bit of difference. We did not let you be identical to your next door. Neighbor. You had to present the image to us beforehand. We look at your design and make sure that it was appropriate for the lot procreate for the neighborhood in wasn't identical to who was around you because this poll overall look was extremely important to us. Also somebody's asked to we give tours. Yes would want gives regular tours one weekend. It's jazz one weekends at Stater one weekend. It'll be art and architecture. Sometimes it's specifically sculpture plast weekend. It was the peach really brothers the six brothers from the Bronx. Carve the Lincoln Memorial? They also that little pink angel. Across the street. They did that for Daniel, Chester, French the guys Lincoln Memorial. We've got lots of custom sculpture out here. But of course, though, six brothers from the Bronx where the guys who carved everything I can find monuments like that. Because now, I know what Tennessee pink is. And they always carve in Tennessee pink. It's their preferred stone type in. So it's real easy to pick out a peach of really one of SIDS favorites is this one foster is Foster's fasteners. He made snaps for gloves. All you gotta to come up with that one thing everybody needs, and you're a multi millionaire after that would tickles me about the monument. It was done in eighteen ninety five is on this side. You see this very flashy signature, and I always think of you know, when you're a little kid, and you start up school in your first cursive writing it. And if you go on the other side, you see his wife's Bertha signature Bertha. Player in this. So much stone. I want to tell you about what he's discovered about. First of all interesting. Structure because it's a actually sarcophagus with a canopy over it a tent, but the tenth happens to be in stone, and the Anna gratitude is very distinctive as you can say pretty much not with any blemishes. We'll talk about that in another place, some some grants have blemishes in it. But you could see a pair. A white material and look at it on the column over here, you can see coming down and that is called efflorescence. So we have a structure that is now has water infiltration, and what it's doing is the waters infiltrating into the joint system and dissolving out the mortar, and then when it comes out on his share fish, the water evaporates, and then deposits the mortar on the the line on the surface of the stone. It's not a good thing. Because it's disappearing. I mean, that's why the west side highway collapsed for the same reason. Of course, the all concrete was being the solve the way and they had tremendous stalactites forming and so flow stone, which is that is called is is very similar to stalactites heights, come down from the ceiling. This comes down on the side of the wall. But it's the same process that forms not only in buildings and structures. But also in in caves, well, while we hear Susan mentioned the obelisks. So here is a a an obliga- that was just finished in the quarry on. It's going to be put on a railroad and carried to to with on. Hey. Popular when two things happen. Washington Monument gets finished Cleopatra's needle good enough for central park. For would imagine. We see this flurry obelisks all over the place and the obelisk who. Represents represents a Ray of sunlight, and then of course, the office always had a goal of cover at the pyramid at the top to catch the rays of sun and big trash down. But it's a Ray of sunlight.
"seismic graham" Discussed on NASACast Audio
"Cores liquid, whether there's a solid inner core like the earth, that's a tough thing to to figure out if we, if we stay there long enough and we get enough really good data. We might start to be able to see all the way deep into the center of the core to see whether that's a it's solidified in center or not. You know, one of the things that you mentioned that really struck me is, you know, the planet is cooling, you know, all all our planets are still in the process of cooling office. Like, you know, they were baked in oven. You pull them out and and and the cake is still cooling off. So so that means we need to measure its heat flow in a have another fantastic instrument on insight that does that. That's right. And and the the heat flow from planet is is really a measure of, you know, the the, the energy that's driving that the geology the planet. So if you see mountains, if you see giant valleys that are formed by rifts or volcanoes, those are all being driven by the heat flow of the planet as well as fault. Activity of the plate tectonics on the earth is driven by the earth's heat engine. So the heat is coming up from the deep interior driving these motions and then being radiated out to space. So we know that Mars does not have plate tectonics. We can see that because there's no evidence of that kind of fault of faulting on on the surface. But we also know that it is radiating heat has got a history of volcanoes, and it does have many faults on the surface a, even though they're not organized as plate boundaries, and that those that faulting is we think mostly driven by the contraction of the planet has heat flows out of the planet. It contracts just like anything as cools off contracts. And as it contracts, it crumbles a little bit. And that crumpling is is manifested in of quakes and seismic activity. So this instrument is called HP three? Yeah, it's called the HP three which stands for the heat flow and physical properties package. And it's it's a really kind of an interesting and cool instrument because it has a little torpedo about a foot and a half long and about an inch in diameter, and it has inside a hammer. So kind of a hammer. It has a motor that winds up a mass on a sort of. Helix attrac- and pulls it up against very stiff spring and it gets to the top, and let's go and goes powder against the nose of it and knocks it self down into the soil just a few millimeters at a time. Bang, bang, bang. And it does that about ten thousand times and can burrow down up to five meters deep into the below the Martian surface. Now, of course, that's on the deck originally, and you've got to use the arm and pick it up and situated. That's right. That's that's our our third deployment activity with the robotic arm. Yeah, the arm has three main jobs. It has to get the seismometers on. There has to put the cover on the size monitor, and then it goes back and gets the heat flow probe, and because we're, we have do things really carefully and get it right the first time it's going to take a couple of months to go through that whole process. Well, it's really need as you say, this hammer has it operates is the seismic instrument on during that time period it is going to be on during that time period and this isn't. You know, one of the is this isn't the the main goal, the mission, but it's really. Cool because those those seismic waves from the hammer of knocking the soil, they're going to go bouncing around underneath the surface and we will probably be able to like, see what kind of layering there is in the top, you know, twenty thirty, maybe fifty feet of of the Martian surface. We think there's actually a more or less hard lava flows beneath this. This layer of kind of broken up soil and gravel on on Mars, and we should be able to get reflections off that and see whether it's even even more solid at depth than and that should be really interesting for for people. And it's actually kind of interesting when we think about astronauts going to Mars in in the future because you know building things on sand is is is not the smartest way to get to go about. You know, putting a buildings stuff, so we'd like to understand kind of what the strength is of the the the Martian regulus so that when we do send people, there will know what kind of Geotechnical techniques used to to make structures, and absolutely the kind of nation. That you make just in those two areas could be very important for human exploration of Mars in the future, but you're not done. You've got other instruments on insight. Oh, that's right. I mean, well, well, first of all, you know, once we burrow down, you know what that he flow a package does is the actual instrument isn't in the in the torpedo. The actual instrument is in the cable that connects it back up to the surface and every couple of feet along that cable. We have a little temperature sensor and that those temperature sensors a measure, not only what the temperature is underneath the surface, but it's measuring how much the temperature is increasing as you go down in, it's only increasing by, you know, hundreds of a degree, but we measured very precisely and we can extrapolate that increase in temperature down deep into the planet. And that's how we actually understand how much is coming out of the planet. So then in addition to HP three and seismic instrument, SEIs you have win measurements that you make cameras. Yeah. We've got a whole meteorological package. It measures the wind speed and direction of the wind. It also measures pressure variation. So as you know, sort of barometric experiment as well plus the temperature of the of the atmosphere. So we have a sort of a complete weather package on there. That was, we'll be running, you know, twenty four point six hours a day and all the Mars. That's right. We're, we're planning to put up a page on the internet with sort of, you know, weather on Mars, you know, sort of like whether dot com except for Mars, and you'll be able to see, you know what the weather was like on Mars yesterday, I don't think we're going to be predicting very much, but you know, we at least been able to tell what the weather's like that's going to be something cool. Well, one of the things you told me just a little while ago that I was really excited about is the is the app on your phone that you can that you guys are thinking of pulling together? Yeah, we're trying to put together a Mars quake app. You know, the US GS has has an app that that'll ill buzz. You when. There's a, there's a an earthquake that's happened somewhere on the planet. You can go and and check it out. We're going to do the same thing for Mars. We're going to have a Mars quake apps, so you know it's running on your phone and it starts buzzing in your pocket. You pick it up and says, oh, there was a a Mars quake out in Tharcisse plateau yesterday and check it out, and you know. So we hope to to be able to to get that it's not going to be in real time because it takes a couple of days to get the data down. But as soon as we get it on, the servers is going to go out to to the to the public, and that should be a lot of fun. We, you know, you mentioned also that the quakes could be from impacts. Yeah. So when a meteorite hits, it's, it's Mars. It's going to make a pretty big seismic signature. You can have pretty small impacts the Martian atmosphere. So thin. Even, you know things. You know, the size of golf ball are going to come in and make a crater, and if it's close enough to to incite will be able to pick those up. The cool thing about that is once we've gotten an impact event. Our seismometers we can go back and talk to the AMRO orbiting spacecraft and the high resolution high rise camera and say, hey, go check out this area. Here. We've got a an impact that happened. You know, somewhere within, you know, maybe ten kilometers at this place. Go see if you can see anything new there and you know they've already kind of blanketed the area around insight with the before pictures, and they'll go and do the after pictures and see whether they can see a new crater and if they can do that, that actually helps us a lot to because then we know exactly where it was, and then we can use all the information from the seismic Graham to look at the interior, not not kind of waste some of it on figuring out where
