 Hi, hello everyone and welcome to tomorrow for August 27th 2023. So glad to have you all here We got a lot to talk about today. We got SpaceX static firing We've got India landing on the moon maybe even a little bit about Russia smacking the moon in the exoplanets That we can actually see so we are officially up and running and very glad to have you all here today My name is Jared. I'm gonna be your host today and it's got some delightful background music You can keep it playing. I like I especially like it when the flute kicks in That there we also got done a bunch of the show and Ryan Joining us as our delightful expert as well. So Ryan, why don't we go ahead and get started? It got a little hot down in Texas, didn't it? Yeah, it did So, you know this week has really become a The week of SpaceX. We've got Starship doing stuff. We've got Starlink doing stuff We've got Dragons doing stuff, but I'll start off with the static fire Because we've got some delightful drone views from SpaceX as always through their Twitter feed and yes I'll still call it Twitter Why am I zooming in? I can just go full screen. There we go. That looks wonderful. So it's just this test is kind of a follow-up test on the static fire They tried to do a couple weeks ago. If you don't remember that last test they tried to ignite 33 engines They only got to 29 and they only did it for half the duration that they expected So, you know, it's kind of you know, it's not that it's not the best test in the world So they wanted to give it another go They rolled it back to production site put the new hot staging ring on top and then they gave it another go at the launch site And according to SpaceX everything seems to have gone pretty much to plan within launch commit criteria Only 31 of the 33 engines managed to make it for the full duration However, that's still within the launch commit criteria I believe they can launch with 30 of a minimum of 30 engines if they have three go out on the pad I believe they're still able to launch at least that was the criteria that they had for the first flight So there you go We've got many different angles from SpaceX Also the daily plate doing a wonderful job as it's meant to dispersing the dispersing the heat energy away From the pad making sure that no concrete really goes flying everywhere interestingly, there were a couple photos of Concrete in places where it shouldn't be but unlike last time when we had chunks of like, you know The size of cars flying around these were like I say probably about that big Which is a little bit more manageable just a few meters away from the pad. So overall this test looked much more much cleaner tests compared to what we've seen before with this booster, you know, it's really The the process is going along smooth and in my opinion we could genuinely see a launch in a couple weeks Which is just like crazy to think about Yeah, and it seems that You know, like I mentioned last week all the right things that SpaceX needs to be doing they're doing they're Really taking their time at this one. They're not saying, you know, we've got a bunch of old Raptors So let's just get them out the door It really feels like the effort is being put into booster nine and ship 25 to actually make sure That it does a lot more than just start doing the cool spinning maneuver up in Up in this guy and that's real. I think it's really good to see that there are 31 of the 33 Raptors working I'm really much more Interested in what's gonna happen when they're not at half power because if I recall correctly That was only at 50% of the throttle throttle. So So you're looking at what is it 8 million pounds of thrust there? Let's see what they it's a lot this test produced approximately 7.9 million pounds of thrust 3600 metric tons of thrust. So you double that and then you have 100% For just 31 of the 33 engines. So then you throw another couple engines in there as well And you've got you've got yourself a pretty powerful booster Yeah, and I think that amps up the environment below at the orbital launch mount So I'm gonna be very interested to see how the deluge system handles that specifically Because it is still at 50% it looks good, but it's still at 50% So yeah 50% that's half of a hundred percent. So we'll have to see again. This is all still testing and in Very specifically, this is all still testing that happens In in the public's eye that was kind of something that I was thinking about this week while watching This which is the fact that SpaceX is really the only really one of the few companies I could think of an aerospace that is How to say it actually doing it in a manner where you could Stand at the fence and watch it if you wanted to Everyone else is really not which opens SpaceX up for a lot of criticism, which is something that you know Everybody and their and their mom on YouTube at least is doing so including us look at us go My mom's not doing it though That's true. So neither is my mom. So she's she's yeah, anyways Courtney Johnson has a really good point here Which is that? Double is a huge factor for engineering and that's very very true when we start increasing power and other things Sometimes you can end up getting quadruple the amount of energy and other things like that So it really really depends here on that plate And as Darren Green is saying so you can't really tell how this plate really is going to do in the real world I think we can To a degree. I think we're seeing that the the plate in the deluge is working To 50% right now as to whether it's going to work to 100% That's where the big question is as to whether that acoustic Environment below in the orbital launch mount is going to be something that will not damage The engines and the engine area at the bottom of the booster I feel like the jury's still out on that But this is why they want to play Yeah, and there's a really interesting point you can see if you watch the First attempt of a static fire with booster 9 compared to the second attempt of a static fire Because the second one ran for the full duration the plume it produced was so much larger So you can just imagine if you then increase the amount of energy that's being transferred You can just imagine how much larger it's going to be I feel like there's still a big margin for energy to be dispersed in that plume because We've already seen between the two tests the difference in size So I feel like there's there's plenty of room for it to go There's plenty of energy to be dispersed I feel like it should be able to cope from the progression that we've seen so far if you follow that curve up It seems like the further you go up it should be able to match what the booster is doing Yeah, and It also depends on what what you're considering to be 50% because if you're talking about 50% fuel flow That's different from 50% valves open, which is different from actual 50% thrust Yeah, so I guess even Even in the terminology that we're getting from SpaceX there's To roll the dice as to what you think they're talking about with that there So I know that there was a very large debate on it on a certain social media platform this week as to what full duration actually means which was Very silly to see that happening Because it as you go from company to company full duration will have a completely different Completely different Definition with that there so it's it's almost that depends on who you ask or I suppose depends on which Twitter account Wants the most engagement this morning But uh My ura sock Sakai is asking if the exhaust enters the holes on the plate Will there be a steam explosion or just rupture of the plate due to over pressure or is the plate designed to handle something like that? it's Designed to send stuff out of it not to have stuff come into it, so I Think that the Scenario where anything could enter would be when the booster is firing and this plate fires Much before and continues going much after the boosters raptors have been firing So I feel like the actual scenario for anything to enter It'd be an incredibly rare scenario and something horrible has gone wrong The plate hasn't fired and then they fire the booster But because they do that before that scenario should never exist because if the plate doesn't go They're not going to ignite the booster because there's nothing to protect it So I feel like that scenario shouldn't ever exist yeah, and Mr. Huggy is saying that they're still having problems with it kicking up a lot of dust and sand outside the launch pad Which I'm sure is very annoying To anyone who puts a remote camera Near that or possibly parks their car They need somebody to sweep first Yeah, let's get out. Let's get let's must out the brooms. I'll do it. I'll sweep those for us We've got it launch pad like Michelangelo painted There and then Darren Green said I feel like Darren Green's got a really good Really good point here Which is that but the static fire previous to the first test flight also made people think it was going to go Good, that's true and this is again as Most of us here are all three of us on the panel are involved in engineering of some sort one way or the other This is why you test And in SpaceX's case Dada, I think you put it really really well Once which is that SpaceX very much believes in the the concept of if you're not breaking stuff. You're not testing so Yeah, this is this is kind of how they're operating and like I said a couple minutes ago they're really the only Company that's doing it out in front of everybody which makes them the one that everyone likes to talk about the most Which means that you'd have people that know what they're talking about You can also have a lot of people that don't know what they're talking about. That's okay So that's kind of how it goes And Maddie's got a really good point or actually a really good idea there Which is that the let's let the robo dogs sweep. So let's get those Boston Dynamics dogs Out there with little grooms and have them walk back and forth on there So that would work out pretty well, but it was just a bit of a blast from the it from the booster doesn't knock them over Just give them push broom mustaches and they can just yeah, I'm sure they could do that Or maybe we could put two brooms on each shoulder or one broom on each shoulder So we got two of them and then Yeah Space dogs and me's Yeah, exactly Don't tempt me Dada now I want now you're gonna make me want to design like like a Harness for my dogs that she can have a broom on her and get her to do her morning zoomings Although both of my both of my hounds are currently in their bed to sleep So so much for domestication And the fluffy of the dog the better the fluffy of the dog the better Okay, well both of mine are fluffy. So perfect So we're let's do it to a great start. Although in this case The concept of if you're not breaking stuff, you're not testing. No, we're we're we are not breaking anything With these tests. So oh, did you hear that? It's time for you to work. Oh, no, it's I'm sorry Bed's too hot. Just laying down now and cool hardwood floor. All right, so It was just Gestion Yeah Spray the area down with water to mitigate dust like they do on construction sites Yeah, and I saw that and I thought that's a brilliant idea. That's a really good idea But every single time we've seen a test of the fire x or the daily system It's left puddles of water everywhere and within a few minutes. Most of it's evaporated because This launch site is at the southernmost point of the continental United States pretty much It's the closest to the equator that you can get in the country pretty much It it's very hot. The Sun is very strong. The water isn't hanging around for long. So this this is a Good idea, but in practice yours is probably gonna evaporate before it has any chance to be useful yeah, it's it's Yeah, getting close to the equator like that. It's a bit of it's a bit of a mess in terms of Stuff like that. So good times So our little static fire wasn't the only thing which by the way, I don't know if anybody has said That's at SpaceX whether they're gonna need another one or not. I haven't heard. I personally have not heard anything yet Oh, it doesn't look like it. It looks good enough for For for what they kind of were expecting in my opinion Gotcha. So basically we just need to get somebody out there with a pressure washer Wash it all off and then we'll eventually work with it, which I believe Some of the licenses I've seen at least coming from the FCC hint at a date of Mid-September probably for the launch sometime around then if I'm remembering the The FCC the Federal Communications Commission, they've I believe what they've essentially done is just extended their their license that gives them permission to communicate with the rocket and the some local Notice to Mariners have been going out near Hawaii and Brownsville of Hazardous areas potentially happening around September 8th However, those aren't like I don't believe that official not Mars to go through whatever system that is I think they're just like local warnings and things like that and they already put them out for August 31st, which is in Like three days time and it's it's not launching in three days time So these are very provisional very local things that are just like hey heads up Boat people something might be happening, but nothing's confirmed just yet Gotcha. All right Well Maddie is asking did we already talk about the Israel moon landing and we have not yet We are doing the interesting thing called barrier lead because we're gonna We will talk about that I hundred percent promise that we are going to talk about that and we'll also talk about Russia's statement that they put out about about Luna 25. Yeah, it was it was a solid one. Let me tell you and We are I mean, we're not done with SpaceX yet. We still got stuff to talk about So do you want to move on to some stuff? Yeah, I got some we've got some cruise stuff to talk about first It's time to fly the meat and bring this one up for you Dutta We got some wonderful drone views SpaceX loves their drones sunset drone or sunrise views of the pad With Crew Dragon endurance on top of I believe it was be 1080 or be 1080 one something on those lines It's first flight brand new shiny booster with the worm and the meatball on the side of the second stage there But this launch pretty much went off without a hitch on its second attempt the first time around we had a scrub pretty early into the count because of a Extra checkouts that they wanted to do with the life support system basically the system that that keeps the crew alive inside of the capsule they wanted to Take a little bit more time. Just check out the system make sure everything was going alright And eventually if I smoothly scroll up to here We saw liftoff of crew 7 on very early in the morning eastern time a bit more of a reasonable time of morning in Europe on Saturday and this booster lifted off and delivered four crew members to the International space station they docked just earlier before the show today and Interestingly for Dragon the four crew members on board. This was the first fully international crew So each different person was from a different nationality. We had Jasmine McBelly the commander from the US We had Andreas moansen the pilot for Issa from Denmark. We also had Satoshi for car I believe from Japan and then Constantine Boris of on behalf of Roscosmos from Russia I just realized that there you go You see more smargon and waving being very happy inside the capsule there So if you see my mouse, there you go. There's Jasmine Andreas There's Satoshi and Constantine there inside the capsule looking very very happy indeed very excited to go But even though they went off on the second attempt Not everything seemed to go Kind of to plan it doesn't go give us SpaceX's as tweeted it But the entry burn for the booster was much shorter than we were expecting We're expecting according to the timeline SpaceX gave us like a 10 11 second entry burn It was literally one second long, but it still managed to land back at the landing zone. So that seemed to be Okay, we haven't got any official word whether that was Not okay, or that was an accident or anything like that but it was certainly A lot shorter than we were expecting And there was also another thing in the final moments of the count within the last two minutes of the count there was a Sensor in the crew access arm that had detected a little bit of the hypergolic fuel that is used within the super dracoat on dragon as a gas now if you get a uh liquid fuel Outside of the vehicle as a gas that means you've got a leak However, they went through all the sensors It went through historical data And I believe they probably decided that this was just erroneous data because they went off with the launch anyway And everything so far all the way up to docking has gone just to just a plan and It looks good for the last mission of SpaceX's initial nasa contract Yeah, and uh, what a what a amazingly successful program this has been I do remember the early days of commercial crew Um, and a lot of people wondering if this is something that's actually going to end up paying dividends Um, and look at what it's done at least on one side of it Um, so far still waiting for the other half with those star liners to kind of kick in and and and and and together With it there, but uh, yeah Thank you, dada, uh with that there. I appreciate that. Yeah anytime now whatever you'd like to Yeah About that So, uh, yeah, and as Maddie is saying it's been so industry changing that is correct Um, because it's it's not just a loud nasa that carry Astronauts on their own independent, uh, Roscosmos now to the international space station It's also enabling private astronauts to go to the international space station as well. So, um, Yeah, but the first time in history private companies and individuals Can literally buy their own vehicle into space. We've seen we've seen private astronauts uh Before but we haven't seen anything like this where someone literally buys out all the seats on their own dedicated launch For a crew launch that's never happened before but yet with inspiration for The axiom space missions the Polaris program this vehicle this program has allowed this new industry to begin developing of private individuals and companies Purchasing their own way into space without having to rely on government agencies Yeah, and it's one thing to buy the bar, you know, when you're out and having a great night It's another thing, uh to buy the spacecraft To buy this out on the spacecraft that you're gonna send everybody with and actually I was talking with the friend of mine about it But before the launch because they didn't they they have been on a they had actually been unaware that we had been launching crews on dragons to the space station and It was uh, it was very, uh, it was it was very interesting At how surprised they were at the fact that you can now buy a seat To go Work on the international space station because I don't think I think a lot of people think that the axiom missions are just joy rides But the people who are there on those axiom missions are there to work And they're putting in work in there They are paying millions of dollars tens of millions of dollars for them to go up and work on projects up there so Yeah, this is um This is a why it's this this is Not what I would have been expecting 10 years ago I wonder if you can write that off as a charitable donation Because you're you're donating your time you're doing scientific research And basically you're covering the cost of you being there, right? Yeah, maybe maybe you could write that off on your taxes So I mean what was what was uh hues and rca and all the other companies doing with their their mission specialist programs on Shuttle in the early 80s like where they I don't know where they writing those off Where they I don't where they even paying that for that at that time So I don't I do not know I would I would think if anybody here would know it would probably be you data Since shuttle is your is your child So Your first child My first love Yes, my first child. That's true. Okay. Okay. All right We all remember our first Yeah, so But yeah, um Yeah, just what a different what a completely different era Of spaceflight. This has become so and it's been it of course is reminding us here in the united states accountants the backbone of the economy so I also think I forgot to mention before but this was the first RTI less mission for a nasa crew mission We saw it with axiom 2 earlier in the year They it was kind of like a proof of concept to see if they could bring the first stage back To the landing zone for a crew mission and they could and all of this is possible because of you know The spacex constantly makes minor tweaks improves efficiency improves performance These rta less missions for crew flights are now possible because spacex has Has gotten so much data from all of these falcon 9 flights that they can see Where they're losing performance and just minor tweaks can bring that performance To assist them in getting to orbit, which then means they don't have to use more propellant on the first stage So they don't have to do a drone ship landing so they can bring it back to the launch site and therefore Bring down recovery times because if you're landing at the launch site your transport is much quicker To say robert's road, which you just put it on the back of a truck and drive it down the road compared to having to bring a Drone ship back to port which can take a few days Then you've got to offload it onto a truck and then you've got to drive it to the to the factory It's that it makes the process so much more simpler for recovery and then this also means missions like these make the cadence Much more increased Spacex initially said they were going to hit 100 this year I don't think they'll hit 100 this year, but it's still an insane number to think about It's it's as well It will be a world record number of flights from a single operator in a year. It's just going it's going to be absolutely incredible Yeah, and maritime and maritime assets suck Yes A certain ceo has said that very publicly before I mean, it's true. They do but sometimes it's the best tool to do the job But if you can bypass having to use that tool That saves you a whole bunch of money and saves you a whole bunch of schedule And maritime assets suck Yeah In our chat room is very much like was that entry burns that super short entry burn supposed to be super super short And I suppose We'll find out down the road. Although do understand spacex is a private company So it is most likely at their discretion as to whether you will ever find out whether it was supposed to be that short or not Um, so yeah, also, um, just want to say a comment from simon anthony as we were talking about axiom space of that Cam gaffer in the boss of axiom has just had triple bypass and is recovering well So cam good luck. Good speedy recovery to you um on that and uh There's been a it's just This has just been a very interesting decade to have watched spaceflight So I know myself and dada who have been In space for a very long time In one capacity or another Other than just simply being on the earth. Uh, this has been pretty this has been pretty interesting wouldn't you say? Oh, yeah I wonder if the uh, the the one second burn Uh, instead of was it was it 10 10 seconds the timeline they put on our website said 10 to 11 seconds That's kind of what they were aiming for and then we see one second and then no one in the press conference asks about it So, you know, we don't really have an answer on that I wonder if they they ramped up their thrust profile so that they can get a speedier return and They've got proof performance that they can prove Or tests for other Aspects of their business Yeah, this was a fresh booster. So um, so they might have thought Well, you know, maybe we can subject it to some more forces than we typically would And if we if the boosters lost on it on rtls no big deal So we'll just we'll you know, it's a fresh one. So who cares God, can you imagine if we lose this one? It's no big deal Well, if we lose I would like to emphasize if we lose this one on entry So yeah, I'm sure I'm sure I I know that people at SpaceX are very much like On on the safety aspect of things. That's that has been very clear No, for sure the start so But at that point at that point the mission the mission is done They they've sent the human the meat. They've sent the meat into space And if you lose it on return no big deal, but that's that's kind of that's quite a a paradigm shift from Boosters being expendable to boosters being reusable and and returning to land So that we can save costs and use them again and now man, maybe it's no big deal if we lose one Well, they've got a lot of boosters. They can they can do whatever they You know just spend however you need to I guess, right? That's how that works I've got a lot of kids, but I don't want to lose one Especially on rtls, you don't want to lose your kid returning to the launch site or landing our dinner site I don't know. So I don't know Oh Man, I still I still was quietly hoping I'm pretty much done hoping for it now But I've always quietly hoped that they would have named their boosters just as they would their drone ships um, but You know that didn't end up happening. So I just thought it would have been funny to hear a bunch of these Names being called out During during flights, but you know wishful thinking on on my part. I suppose so But yeah, and then we also had a quick starlink launch this week too, right? Uh, that's not what I want to show. I scroll up again Did I catch up card there ryan? Yeah, it's fine. I've got it here as someone heavily involved in astronomy. We don't have to talk about starlink So just I'm sorry that out there. So It was um, I'd say it was just pretty much another bog standard starlink We got anus lick 40 another of the 22 mini satellites going up this wonderful streak shot here On behalf of spacex Just you know There's not really much more you can add when yeah, all of the launches are pretty much exactly the same So, you know, I believe this booster was also flying for like a 15th time or something on those lines Or maybe wrong, uh, but something like that sounds about right. They really um They really like to try and push the envelope with these starlink missions Let's see if this booster can fly for a stupid number time and see if it works and it does so there you go Yeah, I I believe the boosters are now cleared to fly up to 20 flights Each and uh, we'll see we'll see if there's further clearance after that for them to continue on um, but very very cool and then We weren't just talking about landing in florida and interesting in interesting different ways that's been done But we also have a landing off of the earth this week as well so Little uh country you may have heard of called india, uh, who is actually Incredibly good at spaceflight. Uh, the indian space research organization Is no pushover when it comes to the work that they do They were they successfully landed on the moon this week And I believe it was done for a pretty cheap price as well It was like 65 million dollars or something which is less than you know movies are made for And to consider that they they they landed a spacecraft on the moon With a rover on it as well as having an orbiter now around the moon for 65 million dollars just seems like a baffling sum of money For such a rich a data rich mission just Why can't why can't nasa Have such a good, you know money to money to reward ratio What how could I don't understand it is where I can do this stuff so much cheaply But yet kind of get a similar result Ryan, uh, first I want to say don't give congress any ideas. Um, so Uh, don't don't let congress have that thought Uh, they're they're already having not great thoughts as it is. So, um, but uh, yeah isro has this amazing ability to come in And show everybody how to get things budgetarily how to get things done um, and It's definitely appreciated in seeing that that happens. Um, It's Darren green is saying, uh, not dealing with subcontractors. Um, that's sure Yeah, I'm sure it's, uh I'm sure it's that uh, yeah, I'm sure it's just that or underpaid. Yeah, that's you. Um with that it it kind of all depends On on how that works. Um, but the shanjun three Mission basically had several primary objectives one of them is getting lander to the surface of the moon safely. The other is Demonstrating a rover's driving capabilities on the moon. And then the other is to conduct experiments on the materials that are on the lunar surface so that we can understand that better and i'm Very excited about all of those because one it's landed. So that's like great two It's the plated rover and it's starting to uh Begin to move around uh for the the time that it will have left Um on there because the lander and the rover are only supposed to last one lunar day And that's daylight Um, so that's about two weeks total So we've still I think we've got about 10 days left Um, uh for the shanjun three lander and rover But i'm really super excited about the composition because not only was this the first time india landed something on the moon This was also the first time we've ever had anything land intact at the south pole of the moon and that is sort of That is a place that everybody is interested in because of the potential for water on the moon now somebody uh in our chat Or in our comments for last week's show asked about you know, what's why does anybody care about water on the moon? Well, uh, it's very important because there's a lot of things you can do with water First of all water is water you need it to survive right you need it to hydrate yourself In addition to that if you wanted to say grow plants in a lunar base or something like that You can use it to keep your plants water get you get so excited. You can wet your plants Um when you're up there on the moon Um, yeah, it takes that. I know you like that. Um, also Uh water What can you do with water like what are some things you could do with water? You guys got you Do you know anything else you could do with water? I'm gonna separate it. You can get hydrogen and oxygen and that's what the space shuttle was fueled with Yeah, a couple hydrogen atoms in an oxygen atom. They sound pretty useful for yesterday fuel and breathing Oh Yes fuel and breathing so we could we could actually make atmosphere out of that there Also, where is a hydro lox or a hydrogen liquid oxygen engine most efficient? Is it in atmosphere? Is it in vacuum? I I believe it is in vacuum Yes, I I think that's what the moon is and I think that brogens lander might also be using Hydrogen for for for some some things as well. So, you know, but this all seems to be kind of useful No way. No way That's right So you could use it for your rocket fuel. You can use it for your breathing atmosphere. Um, also water We use that in industrial processes, right? So If you're going to build stuff On the moon and you need water to do it like you got like you have some sort of You know water jet cutter or or mixing chemicals and water or other things like that there it is So you don't have to take Thousands of tons of water with you To the moon just use what's there. So we call that in-situ resource Utilization So that is like one of the holy grails of keeping people in places or on Surfaces either either planetary or or moon or asteroid wherever you want them to be at Um with that for the so for the finest sharpest cleanest edges I only do my water jet cutting with water and lunar regolith That's very true It should be like, you know A lot of the things that we would often have difficulty with here on earth in manufacturing Um, we can we can get rid of that because we could just do it in a vacuum up on the moon Now that obviously is simplifying The industrial processes With that there in terms of purity and getting things to be able to be Much better in manufacturing terms A product a result of what we're working on at least The moon is great for that because you have the vacuum, but It's still very difficult to convert Things that we do in atmosphere here on earth to a vacuum up on the moon, but still You know So that's that's what we're going to try to do Maddy had an interesting comment about the the the Cost for this mission And she asks does isro have to distribute their production and support systems Across the portions of their country that pay the most to the politicians Uh, don't know That's a great question. So, um, well here in the u.s. That's probably why our that's probably why our missions are so expensive Yeah, I was gonna say should I honestly answer that here in the united states or Or do I want to still be able to enjoy? access to to to these things Because uh, it's that's that's a very good point for here in the united states. Um, I guess that's how I'll say that But yeah, um, so Chandra Chandra on three is Loaded with payloads. Um, there's a thermo physical experiment, which is going to measure the Thermal conductivity and temperature of the lunar surface. Uh, there's actually uh Seismometer on board, which is uh, which is good to measure the the seismic activity Um around there. Uh, there's also another probe that's going to be measuring the plasma density around the surface of the moon as well uh, the Excuse me And then the rover Actually has an x-ray spectrometer on board and then also a laser spectroscope as well So it's going to be able to really figure out, uh, the the, uh The really break down what exactly is the surface of the moon in this area made out of and other things Uh, like that. So I think I'm most excited about what can come from the rover Simply because that's going to tell us about things like distribution of water and metals and other things like that and it's uh, it's That's that's sort of what we've all been wanting to know Since the 90s when it was speculated and then eventually confirmed through several missions Uh, that there was water on the moon Uh, hoan has a good question for you chariot. How has it not evaporated yet? Yeah, that's a really good question. Hoan when um, so How is it not evaporated yet, which I know sounds I know a lot of people would be like dumb question. Okay, let me out But no, not a dumb not a dumb question at all. Um, the Water that we're looking for on the moon It can survive at a Molecular size if you will Um as You know bonded with with parts of lunar regolith Um, and then you kind of would bake it out if if you will I know we're gonna get we're gonna go to the moon and we're gonna get baked Basically, right? So sounds like a good idea. It's um, it's still it's still frozen, right? so two different ways That it would be it would be Bonded in that way. So you would have a hydrate. So like like here on earth you can have um You can have certain elements plus like three four six h2o And that's that's like a hydrate like sodium hydrate or something like that. We do find those on the moon Um, they're usually metals and things like that have we'll have a hydrate attached to them But inside of the moon's craters There are uh, some very interesting things that happen with the moon's craters Specifically at the north and south pole of the moon. Now the moon It does orbit the earth and it is its orbit is tilted a little bit relative to the earth just a few degrees So I mean don't have a lunar or a solar eclipse every time the moon goes around the sun the earth um, but The moon is it's axial tilt or the tilt of its north and south poles is relatively It's not very big at all a couple degrees and because of that there are actual portions of the moon Inside of those craters At the north or south pole of the moon where they are low enough That the sun does not get high enough in the sky To actually go over the edge of the crater you get these Deep areas that are in eternal darkness and have been for billions of years So you end up getting what are called cold traps. So these are places where those hydrated Water molecules can actually end up sort of forming and coming together and depositing themselves over time And you know, you give it a couple billion years and you get these really big deposits of water ice inside of these craters now There were several missions on Artemis one with the cube sacks that were supposed to help us answer Uh, this there was even one that was supposed to try to take images Of it, but it seems that just about every single cube sat on Artemis one has failed in one way or another So we're going to have to wait a little bit longer for that for for direct confirmation but Yeah, it is literally just the fact that there are these these eternally dark areas deep within craters on the moon That are so cold that you can have water remain ice there and the water that Disassociates ends up finding itself in those cold traps and depositing itself on top of more and more ice With that there. I do want to point out That we also know that this is true on mercury as well We do know at the poles of mercury And it's north and south poles. There are also water ice deposits there as well And think about how close mercury is to the sun where it's it's side of the sun Side the face of the sun gets up to 800 degrees Fahrenheit, which i'm messing up in what metric units That would be right now 400 celsius somewhere around there up there goes ryan doing 426 celsius Thank you ryan always got my back. So i know venus is like 450 celsius But there you know to 400 425 around there celsius and you still got water ice at the poles there So yeah, it's possible to pull that off Also, I do want to point out too on the moon There are these very cool things called peaks of eternal light That also exists at the south and north pole of the moon and these are peaks Near like the rims of these craters or large mountainous areas that are always in sunlight as well So you could stick a solar array up there and constantly have power throughout a lunar night if you want it as well In case you don't want to you know go the nuclear option of running your lunar base on a nuclear reactor or whatever Or kilo power fission system or whatever you want to call it you could do it that way So but also like nuclear in space you're gonna have to do it eventually so just do it So yeah anyways there was What what's up? What if I just want to bake moon pies? Uh, well, you're gonna need a kiln uh for that Because I think it's going to be a little different than an oven on the moon With that right um, and then also you're going to need that water You're going to need to melt that water and you're going to have to get the right amount of syrup And carbon dioxide to add to the water so that way you have rc cola there because you cannot have moon pies Unless you have rc cola that is a fact So just so everybody's aware. I think I'm going to vomit Moving on I was going to say in case anybody doesn't know that is a I suppose it in american space flight tradition moon pies and rc cola And there have been me and dada have been at conferences where Eating contests involving those have begun and I've actually been in one before and it really is uh It's Something that's for sure Matty says why rc cola it's because that's uh a very A widely drank cola in the southern united states and that's where a lot of space flight stuff happened Crewed space flights happen because it tastes the best with moon pies By the way, I'm just going to throw this out there. I like rc cola best out of like Coca-Cola pepsi and rc cola. It's rc cola. So and I am proud to be wrong. Let me tell you So pepsi, no, thank you coca-cola sure if you got it rc cola great There is a restaurant near me a southern restaurant that has rc cola only and that is correct. Um, so uh, moving on Uh, because there's a little bit more I just just want to talk a little bit about luna 25 and it's it's litho breaking regular litho breaking I think we eventually termed it last week, which was eventually Confirmed by ross cosmos With this Statements if you would like me to read it out to you Here which said on august 19th in accordance with the flight program Of the luna 25 spacecraft an impulse was provided for the formation of its pre landing elliptical orbit At about 1457 moscow time communication with the luna 25 spacecraft was interrupted The measures taken on august 19th and 20th the search for the device and get into contact with it Did not produce any results according to the results of a preliminary analyses Due to the deviation of the actual parameters of the impulse from the calculated ones This is this is my favorite bit because this is this is definitely a Portion of a sentence that's been lost in translation, but it just comes out really really well The device switched to an off design orbit and ceased to exist As a result of the collision with the lunar surface Especially formed interdepartmental commission Will deal with the issues of clarifying the reasons for the loss wait, hold on It doesn't say the loss of luna 25. It says Deal with the issues of clarifying the reasons for the loss of the moon. So Not only did we lose luna 25. We'd lost Not only did it cease to exist. We've also lost the moon So translation translation. It's a wonderful thing Um, so what I think happened there because I noticed that as well when I was translating it to to put on statements and things What I think because it's called luna 25 Your favorite translating service Decided that luna 25 meant the moon So it said that the moon now ceased to exist Which is not the case. Uh, the moon does still exist. Uh, it is the spacecraft which has ceased to exist Nice else. Thank you. Uh, jared has not me for upgrading your membership. Cheers to you Uh, for you cheers to you for that Um, yeah, I just thought that would be interesting to throw in there because somebody was talking last week about us Laughing about about them that obviously It is it is very much a big bummer because there was going to be a lot of data that was going to come from it I believe they're also carrying a row a small A rover from the united arab emirates, which this is like their second time they've tried to Get a small rover on the surface of the moon and man. It's just really like tough I think it just goes to show that it's really really tough to do stuff in space and also it's really really tough as well when you're Two or three generations removed from doing things like this as well. Um, I and I think that's a great example uh for Why we would even be having problems here in the united states with us getting ourselves, uh back together on that front, so yeah, um It's it's just it's hard. I know we try to shy away from seeing space as hard, but it is Really difficult. It's it's difficult to to say that it isn't hard because it is and it's repetitive to say that it is hard But it is so you there's there's no way around it because time and time again with situations like these from reminded that You know, it's not a stroll in the park to try and land on the moon Just why if your burn lasts a few seconds longer than it was meant to your orbit could be drastically different And that that switches it from being in a stable parking orbit around the moon to crashing into it This is just that that's everything we're playing with thousands of kilometers from home Yeah, you're a paraloon or a parasolid whatever whatever you want to call it suddenly becomes negative altitude and I don't know if you know this but Typically not allowed to have negative altitude and still have a mission afterwards. So Uh, it's frown it's frowned upon And that's one of the benefits of having humans in the loop at the time because you have to program computers to be able to deal with these anomalies and and off nominal situations in a heartbeat and You if the time delay between us and the moon Is so great that you can't even intercede Or or deviate the plan in any way to be able to save the mission because by the time that your signal gets there It's too late Yeah, the velocities when you're out the moon are usually in the time it would take those signals to return roughly Was it two and a half three second round trip or we've already moved a couple kilometers in that time So it's it's a lot and I we talked about that last week about the idea of humans in the loop And you know if apollo 11 had been a computer controlled mission Would have actually landed Because there was that expertise of neil seeing that the that the landing site that the computer was going for Was not going to be suitable to put a lunar module down and he took manual control But helping him out as the lunar module pilot as well with that and got them safely to the surface of the moon so And actually bent it right there Saying that the lunar lander pilots were underrated compared to the computers I think there's also a bit to be said about the computing power that you had in the 1960s I mean after all if you left the rendezvous radar on you kind of screwed up the computer a little bit I'm sure that wouldn't be too much of a problem nowadays with the amount of power that you could you could work with But ultimately It worked and that's that's the critical critical component of it. So Very very good. And uh, congrats to isro for doing so good. Yeah, looking forward to those results coming down so and also This is something I haven't prepared for in advance. So I'm now going to awkwardly Search up is But also I want to I want to commend them because they're public outreach not only for you know, they're They're they're native audience, but also internationally has been really good. They've had so many updates over over the mission the course of the mission from Many many aspects. We've had graphics. We've had number information We've had videos such as this one of the rover Driving off of the lander So, you know, they're they're public great reach in order to inform people around the world of this is You know, I it's really good and I think everyone else should be aiming for for this kind of outreach as well Wow Look at that the prime minister of india as well I also said in his statement after the landing was confirmed to be a success said that this isn't a success for India this is a success for the world and I really feel like their their their outreach through their socials and what not really does kind of prove that Um, that's amazing because you know, they they are sharing this with everybody. Which is yes Yeah, and here's the I believe this is the actual landing Footage that they got out very very quickly after it Um, ryan, are you prepared for me to throw some shade? What have we got? Would be cool if the european space agency had outreach this good We do uh, what's it called? Who let's find it isa.int And then let's see if we can find it. Where is it? Uh, hey, how come I can't get the data from one of the instruments from rosetta still? Why's the pi still have it? Isa web tv here you go. We're looking at we're watching trees a constant complaint Tree this is yeah, we've got we've got brilliant public outreach for me, sir Because we're actually I was gonna say the bark. I should not okay Maybe I have opened the can of worms here that they shouldn't have but that's okay. I could play jamie today um, I just have to say you had We talked about bark beetles there and I was like, oh we have that we have that problem here in california too and Uh, oh right. Yeah, we use satellite assets just like you probably do. Yeah Oh, oh Oh Yeah, well look at that. Maybe I should use maybe I should use websites They're useful. They're very they're very helpful. Are they are they though? Yeah, very sure Are we sure about that? I'm not so sure I don't think you're ready. There's a there's a lot of information there Many photos many many photos also, okay This is something that only me and other members of the media would have probably noticed But I just want to give a big thank you to isa because they've updated their old like media login portal for their photo library Before I'd have to press like the the connection button like many times before it would actually get me in now There's no connection button at all just gets me right in it's wonderful. Thank you very much isa I appreciate it because it means I can now get to photos even even quicker Oh boy, uh, do I feel Do I feel boy? Do I feel much smaller than my little circle down at the bottom of the uh, The uh screen there all of a sudden so Yeah, anyways, um Did you have anything uh anything else for this week? That's pretty much it Thank you for their for their photo library so BS buggy Dada, how about you? Do you have anything for this week? Uh, no, I'm good Oh, okay. Uh, all right. Oh, I just wanted to I've I've been heads down in job searches Yeah, you will that's that's uh, that's good and uh, we're very proud of Dada Uh for that so, um, all right So I wanted to show something which is this So do you guys see it isn't it cool looking? it's a star under It's a big star in a dark spot That's not what stars look like it is not So this is a visual representation looking at it, but this is uh, some results shenanigans So, uh, so this is a star called beta pictoris and this is some Some results that actually came out this week, which look at that x and look at it go across and what is that? What y'all think that is A moon Not a planet or orbiting It is a planet orbiting this stuff a orbiting the star beta pictoris. So that is a planet, uh, which is named beta pictoris b Which has 13 times the mass of of jupiter It's about 1.5 times the larger than the diameter of jupiter as well. So it's a pretty big planet And it orbits it's it's uh, it orbits beta pictoris about once every 21 years So this Is 17 years worth of data all combined into a time lapse And uh, it's pretty amazing that they they've been able to put this together. Yeah, patrick. That's no moon Indeed it isn't um in gth o 42 saying that's one bright planet. Yeah, it is but I also want to remind everybody This is 63 light light years away from us. So this is actually Really really long. Um, and maddy is asking how long was this video recorded over? Um, well, this is 17 years worth of data 17 years worth of imagery From it and you can actually see that at one point the telescope that is taking the data On gets a major upgrade in the early 2010s right there in 2013 It gets a major upgrade to its systems, which makes it look a lot better Um, so which way is it rotating from our perspective here that the planet is appearing to go Uh counterclockwise or anti clockwise around the star So now it's in front of the star and now it's continuing to orbit around And it's continuing to behind the star and then it popped out the other side and there it is Um, no, I thought this was spectacular, which was in reading the paper. They said they said this is great But in order for us to get a full You know to make the full time lapse of this doing one full rotation We still need six more years of data in order to do this So we've still got six more years, uh for them to work on this, which is absolutely ridiculous But I think it's amazing. Um that they've been able to do it now Trying to image an exoplanet Is ridiculously difficult an exoplanet orbiting a star And the the orbit is what 23 years That's it's about 21 years, but they want those six So that way they can get it, you know, because you lose it pretty quickly um, and then we're able to actually you can see that once 2012 2011 comes around that we can actually cut down on the area around the star that is being blocked For the light and then once 2013 comes around then we can really cut down on it so by Six years from now we should have Significantly better technology that we could even that we should be able to have the whole orbit if you will Except for when the planet goes directly behind this or behind relative to us The star that we can see so that's pretty do they have a do they have a reference for how How big that star is and how big that planet is and how How big the planet's orbit is? Yes, uh, so so first of all this is all happening 63 light years away from us beta pictoris is about What is about 75 percent? More massive than our sun is it's about 1.75 times the mass of our sun Which actually means it ends up being about nine times brighter than our sun is And it actually has two planets beta pictoris b and beta pictoris c now This is beta pictoris b and we're able to see it because it is very it is a nine astronomical units away from beta pictoris in its orbit, um, so Uh In terms of astronomical so the earth's orbit to the sun is one astronomical unit So, uh, so nine times the distance At the earth orbits and then also this thing is One and a half times larger than jupiter So this is big and because it is bigger than jupiter and this star is very luminous very very bright Beta pictoris b is able to reflect a ton of light and that's why we're able to see it So effectively here beta pictoris c Orbits close enough to beta pictoris that it is basically within the Shine of the star and and we can't we can't cut down on it like that Um, unfortunately, but yeah, this is just like amazing like we're doing this is direct imaging of an exoplanet Um in orbit and we've been doing it long enough With with the right technology that we've actually been able to get most of its orbit In view here. So but by the end of this decade We'll actually have a full data set that will allow us to see a whole orbit Around the star with this planet. So is this the first time we've been able to do this? Andy lie asks Uh, no, actually there was another one I wanted to bring up that I wanted to show everybody That was that was from a while ago Actually, um, so give me a moment just to pull this up here now this This is from oops Worked out there. All right. So this is Um It's a lot easier when you're not having to do it on live on air. So this is from a system called hr 8 7 9 9 Again, we're very we're so creative when we name things So an hr hr hr 8 7 9 9 is very well known because it is a multi planetary system Um And we have imaged it over the course of about I think it's 12 years roughly Um, and it has an incredible time lapse that I now have up and available Uh for us to look at there are there are Multiple planets. There are four visible planets in this image right here Um, and we can actually see them orbiting around the star. So, uh, so as you can see This is from a while ago. We started observing this in 2009 With that there. So yeah, it's this is this is not the first time we have ever Excuse me. We have ever Actually looked at or been able to see an exoplanet directly. So It looks like a big star too 20 a u Yeah, well, this is a big system. So yeah, this star Uh hr 8 7 9 9 is about one and a half times the mass of our own sun and about five times more luminous um with that there so Which by the way these I I just looked it up real quick. So I wanted to make sure Um on that but these are actually the first Exoplanets that had their orbital motion confirmed by a direct imaging So there you go. Here's here's your first batch That had them here. Um, and mr. Huggy is asking something that actually several of you um Are asking which is what happened to beta pictorus a where did beta pictorus a go? Well Beta pictorus a is the star When we discover exoplanets we we assign them letters that start at b and then further down the alphabet So that's how that goes. So the star is a so the star would technically be beta pictorus a But we're not going to call it that we just call it beta pictorus So and then the planets would be beta pictorus b Which is the first planet they discovered and then beta pictoric c Which is the second exit planet that gets discovered in that system and we go further further further further further further further down the line so So, yeah Pretty cool, huh? Yeah, I like it. So yeah, it's pretty cool Oh, michael bacon. I like that one, which is uh, maybe you should Honey, is that it's pretty neat, uh, michael bacon. I like that comment, which is maybe you should let rocket lab name them so Which would be pretty good. Yeah, I would definitely Uh, love to do that one there. Um, but yeah, isn't this cool like this is a solar system With four planets, so we've been able to actually look at them and see them in motion like wow What a time to be alive so That's so cool. Anyways, that's my nerdy now about astronomy this week So I could do for a long period of time because janey's not here um, so If we don't have anything else, I would like to wrap up our show By thanking of course all of you amazing members and supporters Tomorrow, uh, we cannot do this without you. I think I think that is pretty uh, pretty apparent that With many of you, but I can find my words Here correctly that we can't do this without of you and we are forever appreciative of your contributions to help make us Continue through this This wild world of spaceflight and if you would like to help make the show uh shows Soon to be shows of tomorrow Continue on head on over to youtube.com slash tmro slash join and that Would be where you can do it It literally is as little as 99 cents a month to become a system support a quarter of a cup of coffee And of course we want to thank neuro stream art tomorrow model 33 flat pro plus Member at neuro stream. Thank you so much for helping us out here on the show Now next week we were Next week, we're still figuring it out. We're gonna have a show But we don't know how the show is gonna happen. It's gonna be amazing. It's gonna be amazing. Yeah, so Yes, uh I don't know if I should say it or not. Um simply because I don't want to like curse it or anything From not happening But we have we did get it will be spectacular one way or the other Yeah, we did get invited uh to go do a show somewhere live Um, so I don't should I just outright say it or like they don't want to end up I don't want to jinx it. That's the thing what what what if you what if we what if we stop talking We go to the member show and then you carry on talking. Oh, yeah, we could do that Uh, sure if it's in the member show, we won't jinx it So if you want to now would be a great time to become a member and we'll talk about it there Thanks, ryan great plug. We'll see everybody next week. Have a good one See you in the member show if you want to know if you want to know what would you like to know more? So and secretive
