 7th 2024 so glad to have you all here with us of Jared gonna be kind of quarterback in the show today I've got over to this direction to be done up our director in the middle and we've also got Ryan With a great shirt on circuit of the Americas. I've been there before a cool place And if we hope that you are having a great weekend wherever you may be Or if you watch the Zuka or something this weekend or if you are in transit as I am going to be very shortly Today so where should we begin our discussion today because in spaceflight there was just a lot happening this week like an unbelievable amount of things from an from a Huge number of companies right SpaceX had their sort of annual shin dig of you on give you some update Yeah spaceship or starship. Thank you Exploitation starts with a verb. We also heard from relativity as well. We got a little hint of terror and R We got some more from launcher and believe they were tested their bigger engine Stokes base as well as working on their first stage Revealed a bit more. It's all over the place. Of course. I want to say hi to Tony ship it Saying hello from 35,000 feet headed to Boston and then the Vermont for the darkness Yes, indeed and I'm gonna be leaving in a few hours to go to Texas For for what will possibly end up being cloudy darkness But Tony enjoy that and good luck and good weather to all of you who are gonna be hunting tomorrow So where should we where shall we begin because there's a lot besides just the eclipse and that to talk about Let's I think we should do a little spaceflight first before we jump into the eclipse. What do you think? I think that's space space white stuff first. Yeah, yeah, let's do it. So I'll give you a hot fire round up if you so desire of the being a a very Expression for what's been going on over the last desperate for one, right? Give me one So let's kick it off with relativity terror, they kind of launched unveiled a New look at the aft end of their booster their first stage with an interesting array of 13 Engines and kind of a a crisscross pattern. So it's not circular if you imagine the The the engine array on falcon nine with nine engines in a square. So three three three They've kind of done that but they've got like three five three five three It's a it's a diamond with squares on the points And then a single in the center, right? Mm-hmm So this is to look at so I think the reason they've gone with this approach is because If they did say 10 on the outside And 10 engines around the outside in a circle and then three in the middle They wouldn't be able to just ignite one engine for a single engine burn Which as we're sitting with falcon you may want to do if you are doing things like boost back burns or entry burns Or landing burns, which I'm sure relativity intends to do in the future So I think this it looks kind of Looks a bit bonkers But you know thinking about it beyond the aesthetics It kind of does make sense a little bit and it will certainly be very exciting to see That engine array fly for the first time and hopefully not too soon Of course, they are currently retrofitting their launch pad for that A much larger rocket than terran one Was so yeah, I'm excited to see it fly. It's kind of Originally was going to be baby starship and they've kind of gone down their own path now Not I wouldn't say abandoning 3d printing, but certainly cutting back on the idea Everything has to be 3d printed and instead going for the more traditional Um, like uh rolls of steel, which they're going to be turning into rings and then and then stacking like Many different vehicles have in the past So yeah, relativity doing good things doing making making nice progress Certainly, uh, one of them companies to keep an eye on another one of those companies to keep an eye on is stokespace because they uh, or rather their ceo and elapser and founder tweeted a picture of the engine which will power their first stage and um, he did There were loads of replies to the tweet. He did respond to a lot of them and he kind of said well, this is a bit of a A test bed engine bit of a development engine However, he also replied to a reply saying that this could be flight hardware And then the day later from stokespaces actual twitter account They tweeted a picture of it mounted on a testing rig So stokespaces made tremendous progress in their engine in the last few weeks and months Of course, we saw them not that long ago rolling out a scaled down path find a development tank to test with And now they're already moving on to testing engines for their nova rocket And uh, if you didn't know, uh, stokespace was founded by a couple people who left blue origin And they were and elapsed specifically worked on the be4 engine Which we saw perform flawlessly on vulcans first flight. So, you know, these are smart engine people at stokespace They know what they're doing and this picture that you can see right now I mean You can see that it's definitely not as say as As tucked in and as concise as the head of raptor is but that's a cool looking engine I'm a I'm a fan of this engine. It looks very cool. It's definitely spaghetti at the moment You cannot doubt that but it does look I do like the look of it if I haven't made that abundantly obvious already Yeah, I like it. I like this engine Yeah, I think it's important to remember that this is very clearly a test rig So this is not uh, this is not at all what what will end up flying Um, so, you know, you got to you got to make sure that uh that you understand that it's going to be a little bumpy in terms of its looks Without there. So it'll be much more tidy when it comes time to play. Yeah. Yeah And then I was gonna say if we wanted to go back. I've got the relativity space image of uh, Oh, yeah, let's take a look at it. Um with that there. So, um, Yeah, it was absolutely fascinating. Um What they were doing Uh here and I'm trying to pull it up because they've got a uh whole thing on their twitter here There's a fun one. Yes. I'm gonna share my screen. Don't worry There we go. I saw I saw it in linkedin and Yeah It's definitely an interesting configuration to say the least but but like you said ryan It's it seems to be the correct one if you are trying to do that burn Uh that you need but also still have the power that you have so yeah, and um If you think back to falcon nine square array it was Uh abandoned because spacex wanted to simplify the design of that end of the falcon nine to have the same engine Kind of housing eight of the same housing and then only a second Circular one for the center merlin on the falcon nine. However in negativities case 13 doesn't divide nicely to have a single center engine unless you do a configuration such as this so I can see I think it makes sense to okay. You're sacrificing some um similarity between each of your engine housings but You have a design. You have a vehicle design which allows you to perform It gives you many much A increased number of options shall I say When you are going in for something like a landing burn, which is mission critical in order to land the booster So something similar to what starship did when it was doing it like 10 kilometer hop flights They'd ignite two or three of the engines that they had and then cut back down to one for the redundancy of seeing if Any of the engines would work. I can see a similar they uh regativity wants you to do a similar thing Which is why they've chosen this engine layout So with this this layout they've got the option of of one engine three engines four engines Five I think six Maybe even seven As all symmetrical thrust profiles Like that's that's a wide array of capabilities there. That's that's actually pretty smart And by having that kind of crisscross pattern in the middle if they need three engines But they lose what like say that they lose the one over here They can switch to those three engines because they'll do the exact same job because it's all symmetrical Right exactly. Yeah, very nice way of handling it So I quite like that So it's almost like smart people work in the aerospace industry What I've never guessed Never thought about this Yeah, so All right, well, I mean, you know our uh Our chat room is pining for it, of course From john a comment from john t there saying starship is getting much bigger. So I guess we have to talk about um, I don't want to call it the elephant in the room, but I mean It is starship is becoming bigger Um, in the sense that it might become bigger question mark Yeah I mean it was always on the horizon either I I don't I don't think there has been a a starship kind of announcement or Presentation or talk from Elon Musk that hasn't mentioned starship getting bigger over the last However many years. It's not like this is a big shock. It's just the first time that SpaceX has as publicly released a render of a taller starship with starship v2 Being approximately the same size as we have now the booster growing a little bit with a a At least a different designed hot staging ring in the render. Um, but then starship version three growing like ridiculously more the booster is going to be like 100 or something meters tall the ship is going to be 70 something meters tall. It is like There are no words in it. It's big. That's the only word you can call it It is going to be so big compared to starship at the moment and starship at the moment is humongous So it's getting even bigger. The physics are getting even crazier. You know, it's just like I'm fathomably large And this thing is going to fly through the air and into space just like it's any other day. I mean Yeah, it's it's it's it's it's kind of berserk I know right like I'm just I'm very much, uh It's just Man, it's amazing to think about just how big this thing is going to be and then catch as well Which we're talking which was being talked about yesterday um Just like man, that's going to be absolutely spectacular when that happens Seeing that Like cheese like either that is going to be like one of the most I think that will be more spectacular than than seeing uh salt and iron land for the first time um to get caught by the chopsticks, um And then That's either going to be one of the most spectacular things I've ever seen. Um, or that's going to be one of the Uh, biggest if you're a welder move to the move to southern texas projects You've ever seen in your life. Um in either way, it's going to be excitement guaranteed For sure with that so I'm very much it'll be exciting to see and if you're a welder you might have a job afterwards Yeah, yeah, you might be looking at a big payout Um coming from that after all so, um, yeah A few things a few things around the the watch site obviously we don't want that to happen We want it to work the first time Um because if it doesn't work it is gonna be big boom, um, but you know, so it's welcome to aerospace It's kind of how it goes so So, yeah, yeah For the timeline of that which I thought was very interesting now It's not sure whether this is spacex time Gwen time or elon time However, it was said in the presentation that they are going to attempt a a virtual catch Tower which I assume is just an imaginary catch in the Gulf of Mexico On flight four which is this coming flight and if that goes successfully They will attempt an actual catch on the actual tower for flight five Which assuming that the launch follows a one and a half two monthish Kind of timeline like we're predicting with flight four Say after mid-may that could be July For the first actual catch attempt assuming everything goes as planned on flight four Which is like the increase in size also kind of bonkers because Like even on falcons development scale They didn't attempt a landing on a drone ship or a landing on a ground pad on flight five And this is the world's biggest rocket ever built in terms of size in terms of mass in terms of thrust And they're going to take the first stage of it and catch it with two arms Sticking out of a tower On its fifth flight Now the process is berserk as it is but flight five is just I just I just can't fathom it You know, it would be interesting as if they they told the tower That it was in some imaginary point in the middle of the ocean And related the The mechanics and the navigation of the rocket to The tower And made the tower think that the rocket was coming in and actually did the chopstick arms and all that And we could we could see both in parallel screens at the same time that would be really cool Yeah I kind of I kind of thought of something like that a little while ago And it would be like well if they just take the booster's telemetry offset it by however many kilometers down range it is right, and then it gives you like Although I have to be honest I'm a little bit pessimistic if the current chopstick systems will work because they are squeaky when they lift ships and boosters and they are not going as fast as they'll need to be going When lifting as when catching so I'm a little bit pessimistic, but it will be the current chopstick system But flight five. I mean I don't think they could build a brand new orbital launch tower orbital launch mount and chopstick system by july You know, it's april that would be three four months of construction to build all of that. It's just ridiculous. So I'm I'll be honest. I'm pessimistic, but Maybe it's already built Come in In a way it is because the tower sections have been already constructed at the cab and then being the Five or six of them have been barged over to port of brownsville and and and there's Some construction going on right now at the production site And to prepare to to stack them all together. So they have been prefabricated, but The orbital launch mount ring is something very interesting because So we spotted on satellite imagery that it has been rolled outside of the hangar at the Cape However, it's not sure if they're working on it going to take it to the pad Because at 39a they've been demolishing the launch mount legs Which makes me think they're not going to be using that for the pad if they've just demolished it So it's interesting But then that thing is also very big very heavy and I don't think they'd be able to get it on a barge But yeah, we'll just have to wait and see what actually happens with the second launch mount at starbase So would they be launching from Boca Chica and trying to land the booster in in florida? I don't think so because the booster would need to expend a lot more fuel in order to get to florida In terms of the actual trajectory of the flight I don't think the booster would would be able to to make it to the Cape Especially over flying land. I'm not sure who many how many people would be, you know flying over central Orlando With a 70 meter tall development prototype booster. I don't know how many people would you know? Let's go for it I think I think I'll tell us to Boca Chica. It is a much more realistic and dare I say safer proposal Mr. Huggy has an interesting proposal here, which is well space x is wanting to upgrade the t having to be wrecked by it Good way of doing it so Yeah, you could just use your booster to take out your launch tower and voila you You handled test Uh-oh, I must have said something and upset someone I disappeared there for a second. Um Are we are we streaming on x? anyways The uh You could handle it that way. Perfect. Thank you, mr. Huggy always the internet's always full of great ideas, right? So Right, isn't that good a day maverick asking for an ift4 date. I would imagine That that's probably Not in the cards at the moment for us to know like like the data review still needs to happen and things like that so I personally haven't found anything yet. Yes It I'll lay out all the things and then I'll make my decision because I haven't like 100 thought through it yet so Elon has said in his talk Which I'll assume was this past week because it wasn't live. It was just posted later. I'll assume it's in the past week Uh, he said in a month from now Now assuming this is the start of april that could mean the start of may So let's be a little pessimistic on that date. Let's say second week of may third week of may But if we actually think about it After flight three took off spacex managed to roll a ship to the sub orbital launch stand b Static fire test it twice Roll it back Roll the booster 11 for flight four to the orbital launch mount stack it on there 21 days After the flight which is ridiculously fast compared to flight one and flight two And then they fired all 33 engines of that booster for about seven seconds 22 days After flight three launched And if you kind of if you take that change from flight one to flight two and flight two to flight three And now the flight three to flight four testing campaign you can see it getting significantly shorter every flight So I think that from november to uh march For flight two to flight three. I think that can be you know, realistically shrunk down From march to may because that's essentially four months to essentially just shy of two months or two months I think that is a realistic time frame now. I may seem stupid or ridiculous for saying something so ludicrous But spacex have proven it with the test campaign So I didn't really see any reason apart from regulatory hold-ups why the hardware wouldn't be physically ready They've tested the ship. They've tested the booster. They've both they've said both went successfully So what's stopping them from putting them on the pad and launching them once the final touch-ups are done Their development moves at ludicrous speeds. So your ludicrous Assumptions on timelines. I I don't think are unrational Yeah, it's all it's all super fast. So, um Probably know they could be ready in a launch from a week from now. So, um, if not even sooner honestly Um, what's up? I'm seeing John John T says they've unstacked as of an hour ago Yeah, like literally the booster has just been removed from the pad and they have a roll out closure tonight from 10 p.m To 3 o'clock in the morning central time. I mean the they don't stop man by 3 o'clock tomorrow morning The booster will be back probably in the mega bay at the production site ready for touch-ups and they static fired a couple days ago They static fired on friday. I mean the the pace is ridiculously quick But they are doing it and they are making it real Which yeah, just it doesn't make it seem ludicrous anymore Even though it is like it's it's utterly bonkers No one else in the history of aerospace has moved so quickly with the rocket of this scale Other than falcon nine think of a rocket which fired Took off and then 22 days later static fired on the exact same pad again I mean You have to move faster to disrupt the industry, right? You have to be able to iterate Quickly otherwise you just burn through cash Stephen Lewis has a has a suggestion of 420 and that doesn't seem like an unrealistic target for elan It doesn't that's what I'm I I'm a little pessimistic on that one But I like I wouldn't be shocked if it happens on there I'd be like, oh, this is faster than I thought But I think may is certainly the target internally for SpaceX based of what if you're thinking quicker than elan Elan thinks quicker than anybody else. So I think thinking quicker than elan could be slightly pushing it a bit Yeah, and then even even elan You know, even as mere mortals like elan still have to obey physics and and other things like that So so there is an action. I do want to say there is an actual limit That doesn't mean you can't build right up to that limit and stretch it as close as you can But do understand that there are limits Uh, but physics don't tell me there's limits Don't tell me there's limits. You go you go faster. Go faster now. Go But I'm gonna say that there will you will always approach a point where you will get Diminishing returns as to what that looks like it is going to be absurd compared to even what SpaceX is doing right now So let me just cool. Let me just qualify. Let me put a little asterisk on my you're not going fast enough. You're fired Thank you for that, I appreciate it Um, but yeah, I agree a month sounds about right Uh for that and then mr. Huggy saying, uh, I could easily see turnaround times Of about months later this year. I honestly I'm a little bit more optimistic now that I feel like They've got stuff better on the uh on the launch front. I think they're going to be able to maybe get it down to three weeks Um, I would love to see them get it down to a month. I'd love to see them push it Um, and then Dave's basically saying first Week of may in that area Dave Avery Um somewhere In there, so why not launch on a saturday? Why not saturday is delightful go out. They're they're de stacking on a sunday. Who cares? Yeah, go out have a picnic. They don't care about weekends Go surfing for a little bit then get off at the beach just in case because you don't want like to catch any souvenirs If something goes wrong, um, and then you know, just enjoy yourself once it's all done go back out and enjoy yourself That's the way that's the way it works. By the way, I you know Somebody would probably be very mad that I said that about Boca Chica I imagine go to the beach surf get off of the beach So you don't catch souvenirs could also apply to vandenberg as well. So don't don't think i'm just limiting this Um, so it's what we what to just texas With what they've got there. I don't think you could do that at the cape, right? Mr. Mr. Huggy says after 420 the best meme day would be may 4th Or may 5th So don't forget don't forget uh the may 5th people If jamey has her I'm sure I was gonna say for jamey may 5th would be a bit bigger than may 4th But also I don't want to speak for jamey As well on that Yeah, so Cool. Well, uh, we'll have to see Uh, we'll have to see what happens either way. There's a lot going on on that front. So very very exciting Yeah, cool Anything else on the spaceflight front this week where we I think I mentioned launcher, right? Yes, uh, so launcher test fired their e2 engine, which uh What's the word what's the word i'm thinking of uh creatively means engine two And if you didn't know a a few years months ago launcher was Purchased by vast the space station company. So vast launcher is now a a subsidiary of vast I don't believe that they are now continuing development of their launch vehicle How because they were going to develop a small sat launch vehicle to compete with the likes of electron and terra one and Astro rocket four however only one of them is flying today. Um, the Engine development side of launcher is continuing to develop engines Which I believe will be able to be sold to other Companies who want to use their engines so a similar model to Say like the new space people such as some major who are selling their engines to strato launch or Even you know more traditional aerospace manufacturers such as say aeroget rocket dime who build engines to sell to other people To put on their rockets. So I think that is a very nice step Launcher to actually get a clean from the photos clean looking test firing of the e2 And very interestingly even though I think it's an rp1 liquid oxygen engine The flame burns very blue and it looks very pretty Which may have some people thinking i'm sure there's a smart chemistry answer for why the the the flame was blue Um, if we have a smart chemistry person in the chat, please feel free to explain it to me But I i'm a bit confused why it is my best guess isn't it has something to do with the oxygen? um, but I I At least I feel like I have been told historically blue flames are for methane or metha locks Engines and not karagox engines Yeah, that's interesting. I wonder if it might have to do with uh the a blade of properties of the Of the nozzle on there if it's a blade if I don't I don't actually know what the nozzle is um But yeah, trying to figure that figure that out So it's an interesting one to look at so Yeah, it is very pretty though. I got to say from looking at the uh the videos of it. It is it is a gorgeous plume coming off of that uh that engine there so Big fan of it So I always like there's some good mock diamonds in there too. I think so So yeah, yeah, it's uh, it's a very clean sharp flame. It looks it looks powerful Probably is powerful. Um, and yeah, it's uh, it's looking to be a solid engine From a testing standpoint. Obviously it hasn't been flown yet, but you know Before you can get good flights. You need good tests. So obviously wish them the best of luck in developing that Yeah, 22 000 pounds of thrust uh coming out of that that uh that engine. So It's a good good amount good clip for a small small sat launcher Uh, so if anybody's in need of an engine for their small sat launcher Looks like launcher A subsidiary of vast boy, that's going to be that'd be a heck of an acronym to work with there Um It's Seems like it seems like there's some talk about the color of the flame emitted being related to the temperature of the plasma coming out of the engine Oh, yes 100 so if you so even with with uh, locks kerosene if you can run it hot enough Then you can turn the flame from orange yellow to blue ish But it it still had little streaks of yellow. So it's evident that it's not methane Only it's or metallox it's it's still keralox They're just running it really super hot Yeah, and uh, I was going to say just you know, astronomy over here Things that are bluer or hotter and things that are redder or cooler. Um in terms of light being emitted. Um, so So like when you see blue stars, they have a much higher surface temperature than say a Yellow star like our side or a red star like uh, like uh Proxima centauri, you know something like that. So yeah So the more the more you know, I guess, uh, you you are you might be today years old to have learned this Um for all I know so there you go liquid liquid hydrocarbon The color is mainly a product of microscopic particles of carbon soot glowing like a perfect black body Uh, because black body color is not Quantized the color of the soot becomes bluer as the temperature of the flame increases Excellent that's a little physics there. I'm going to pretend like I understood everything or thing you just said burns hotter Okay, I understood that the bluer the the bluer the flame the hotter the stuff So that that poses I guess it poses an interesting engineering challenge then because they're if their flame is burning hotter Then they need either more ablative materials in their nozzle or active cooling in order to be able to keep it performing for the duration of a flight Yeah So Yeah, I wonder I would imagine methyl ox must burn hotter than keralox does To begin with right. Yeah, it does because the light and it's got more energy Yeah, and we're getting more energy out of it. Yeah. Yeah, so yeah, this is gonna be hotter So anyways, that's a spicy. That's a spicy keralox engine there. Let me tell you so Um, but it's actually really really cool. There you go, everybody You watch tomorrow for the space flight to get a physics lesson. So from from dada In that case, so thank you dada. So appreciate it a slight amount of astronomy from that, I guess for me and then um Like ryan, we all get to learn together With this with this here. So anyways Uh, so what do we have anything else to talk about before we move on to I guess the barrier lead of the day? Uh, I don't think so. I mean speaking of astronomy. I think there's there's there's no nicer most spectacular event coming Sooned and what's going to happen tomorrow across the pacific ocean Uh, and and north america and uh, and a teeny little slither of europe Yeah, and it is uh, indeed going to be a very very big deal. Um, unfortunately the only map that I have Uh, what's up dada? Let me guess. It's not the teeny little sliver sliver of europe in which you reside Uh, no, it is not. Uh, it is a partial eclipse in scotland a bit of northern england ireland The azores islands uh iceland's the faroe islands. Um, but no literally the opposite corner of the uk to me Huh, is there so there's no part of the uk that's going to have Total there is at all. Uh, no part of totality, but it'll be a partial totality ends. I'd say probably Just shy of a thousand miles from from the atlantic coast of ireland. So uh, because unfortunately we we're not We if the earth rotated slightly slower, then we would have been able to see it. Let's put it that way But unfortunately an earth day is 24 hours and a bit. So, you know We we just slightly cut off, but if we just changed the you know the orbital mechanics Uh, well then we wouldn't have the eclipse at all. So, you know, what if what if we just what if we just move the moon Let's have it. So we have a total solar eclipse Once a month for everyone to see Oh boy, this is this is that scene from austin powers where the president is like He's like just let me shoot all the missiles at the moon and the general is like are you suggesting me blow up the moon And I always like how the president goes. Would you miss it? Would you miss it? So, um, I'm sure I'm sure if we put enough rocket engine if we've fired all of the rocket engines In the world in the correct direction. I'm sure we could slow down the earth enough Um to get totality to you Ryan so According to reddit. I once read that I'm sorry. I get one a year. There's my one reddit joke a year. You're welcome. That's it. That's it That's it. So, um, but anyways Um for everyone else that is getting have totality Um, here we are, uh, at least a united states centric, uh version of it here Well, you can kind of see a bit of mexico and a bit of canada Yeah, and I mean canada's gonna get it a bit, um mexico's If I recall correctly, mexico actually has the area where they're gonna have the most of them totality I think it's somewhere near four minutes 40 seconds Something like that also often the, uh, pacific ocean off coast of mexico as well But for most of us, I'm sure our viewers Um, yeah, we're gonna be in the united states here and uh, probably doing our best uh Doing our best to I don't want necessarily say scream down the highway to try to find A open patch of sky But it's definitely not looking as promising as everyone was expecting it to so I guess just to kind of nail it down Where we're gonna be at you're gonna be coming through the texas area here clipping a little bit into oklahoma Arkid saw as well going into Missouri Here very slight amount of kentucky tennessee if you're kind of on the corner of tennessee there You should be able to do it a little bit of illinois indiana Also, ohio warning you are in ohio Uh, slight amount of Pennsylvania and new york there Along with vermont new hampshire and main and then we're going into Our neighbors to the north canadia Up in there and I believe it's newfoundland. That's actually going to get a lot of uh, A lot of that as well Where are some of the big some of the big, uh, cities in here that we're looking at burlington in vermont Buffalo rochester and syracuse and niagra falls in new york Cleveland you're going to be in it holy to lino you're in it too along with akron ohio Let's see some other big ones Carbondale illinois which actually not only were they not only are they in the center line for the 2024 eclipse They were in the center of totality for the 2017 eclipse as well. So uh, they got a double dose of eclipses within a decade Seven years apart, which by the way on average Uh, what wherever you are on the earth will get an eclipse about once every 375 years. Um, so everyone in carbondale buy a lot of tickets tomorrow But you uh, but uh, you have to have lived, um, you have to live in carbondale. That's the that's the key to that Um, let's see also little rock as well in arkansas or as my grandmother would who was from arkansas I would have said arkansas Texarkana and dallas and arlington fortworth. That's the area that i'm going to be in Um, probably screaming across the plains. They're trying to figure out where to go. Uh, austin go away class antonio Yeah, basically that's what I am myself in a multitude of others Are going to be screaming At this because we were all told The texas was going to be the best weather like that was the place to go. But guess what? Turns out not really looking like texas is actually going to end up being the play The best place for weather at least here in the united states Anybody want to take a guess at where the best weather in the united states is going to be new england New england yes Yes, indeed. I can't be irony the utter irony If you want to have a cloud-free view of the eclipse you need to go to vermont new hampshire or main Places a well-known Four clouds and they're cloudy weather. I can't believe it Like of all the places Uh with it here. There's at least a little latest predictions, uh from our friends over at pivotal weather As you can see A quite a substantial amount of the united states is out of luck So it goes that's just you know, welcome to the eclipse experience with it. Um, that's kind of uh and And let it be said that even if you're not in the path of totality still look at the eclipse because it's still really cool They don't happen in in your area all that often. So wherever you are If you're anywhere near a partial solar eclipse, it's still going to be cool to look at don't look at the sun directly Only use need to be wearing these cert the certified glasses Or make a shadow on a piece of paper Mine set of flames on them So they're really good They give these are at least worth 10 to 15 extra horsepower That's that's not your redness burning Uh It could be it very well could be uh with them there. I have no idea where anybody is Um right now because I can't see anything Um We did everybody go. I don't know. Um, anyways, I won't be able to see any eclipse But I'm still prepared because it is important to not look directly at the sun because if you do that Yes, you will be blinded and and no one wants that so do not look directly at the sun wear proper glasses If you if you if you even if you have a pair of these if they're damaged or scratched Do not look at the sun with them because they won't do their job No, they won't need a healthy pair of solar viewing glasses yes a healthy well cared for emotionally happy pair of eclipse glasses so So yeah, um It really honestly we're making a bit of a joke, but you do actually need these Um, or like you said data a pinhole projector Which one way you can do that you can actually like just basically take something Um, like cardboard poke a very small hole in it And then anything that's got a hole in it makes it makes a cool shadow Yes, put it a distance away from something you can actually do it I do want to say for the annular eclipse that we had in october when I was up at work at grip with observatory I literally took my hands and I just did this where I made a little like Crosshatch pattern with my hands and I was able to get a couple like projected images of of a Crescent Sun through my fingers. So like you don't even really need a hardcore equipment with it there. So um, so Um, I do want to say in our comment section a few people have said welding helmets I always say don't do a welding helmet because you never know Um, what the iso approval is going to be on a welding helmet. Um, it's always a roll of the dice with those um, so Don't do it. Um Sunglasses don't do it If you're technically minded enough to understand the iso certifications for the the particular welding helmet that you're using and they match exactly To the iso requirements of solar of certified solar glasses That's acceptable But yes, we cannot say And it's typically not the case that welding helmets welding goggles grinding goggles any of that stuff Is the same has the same certification. So no Not welding helmets. Yeah, not sunglasses Not no Solar solar eclipse glasses Telescopes and binoculars absolutely Not I don't even I know some people say that oh just use your telescope as a Projector for for that and I always say don't even do that Um, because you don't know who is if you don't have an eye on your telescope the whole time Or you're not standing right next to your telescope You don't know who's going to walk up to it and put their eye right in the eyepiece as it's staring directly at the sun And basically that's it that I's done immediately Concentrated blindness Yeah, it's essentially it literally burns your retina And that is instantaneous blindness. So no to telescopes. No to binoculars if you have solar filters that are Of quality and they are not scratched or damaged in any way you can But these are the kinds of things that you need to ask A professional about Much like the welder's things, you know, I would if somebody was a welder and said I've got welder's glasses for it I would trust them a bit more than just a regular member of the public saying I went to harbour freight this morning and bought A welder's mask and I'm good You know So ultimately If there's one thing I could say about an eclipse it's that for most of the time of the eclipse don't look at it Um, but once you get if you are in that path of totality if you're in that that area Here in the united states, um, or canada or mexico or the atlantic or pacific wherever you may be Um, if you're in that dark line If you're in that area where the sun is going to be covered fully by the moon, uh, absolutely Take take a look. You're gonna get some time. Uh, yes mark, uh You can only take the glasses off during totality and there are some Some very key moments as well that will tell you when it's okay to take it off Um, usually when things go immediately dark, you're still not quite at the point You'll have what we call the diamond ring Which will be this point where the sun is still there's still a sliver of sun there and you don't want to look at that directly You can look a little bit off to the sun like way off to the side of the sun to enjoy the diamond ring Um, and then you'll get these things called bailey's beads, which are basically the sun coming through very uh low valleys on the side of the moon, um, and then It'll officially slip behind the moon and you'll get totality and you'll see the Uh, unbelievable corona, uh of the sun And i'm not sure what the predictions are showing for this year. I was actually going to pull that up right now But I remember back in 2017 uh They got spot on And I'm hoping they'll have some good stuff Very quickly Yeah Whilst you look for the for the predictions I I've brought up my notes here for the nsf stream tomorrow, which is just totally watch, uh for so, uh, Mexico the united states and canada are the countries which will be able to see a The totality and I have a list here of other places around the world which will be able to see Partial, uh, mainly focused around a significant partial which I've kind of classed as approximately 50% or more Which is in a in roughly this order Kiribati French Polynesia the u.s minor outlying islands the kuk islands Guatemala Belize the caiman islands cuba the Bahamas Bermuda Greenland iceland the ferro islands the azores island and the united kingdom So if you are in or near any of those places You will at least see a partial solar eclipse Uh, maybe fingers crossed Yeah, hopefully hopefully you'll get it That area there, um, I have found, uh, the eclipse prediction and it is absolutely, uh Stunning I was just sort of this is coming directly from nasa as I pull it up here And if this is what it's really going to look like I am going to probably Uh pass out Seen that I don't think the colors Are going to be there. Um, but that's Unbelievable if we're going to get, uh, huge streamers from the corona looking like that That's going to be massive and then planets, uh, like jupiter Venus Mercury Mars and several of the brightest stars in the sky serious and bacon several others will be visible If you're in the path of totality, uh, take a look around you because Uh, you will see essentially sunsets the red of sunset and sunrise in every single direction around you It's a very eerie, um Experience I remember that that was I think the weirdest the weirdest thing for me was seeing that you're used to seeing it Where the sun is at? Um, not entirely around you 360 degrees. Um, and that was Unbelievable, uh, you mean we can see mercurus Mercurus. Yes. This is one of the few ways you could see mercurus Uh, uh mercurus the sun, uh Uranus water planet, uh, plateau And uh, this one's too far away. They don't have a name for it. So Everybody knows what Anything that creates a shadow if there's a hole through it Will project, uh any clips including the the holes between leaves and the trees Yes, absolutely. Um And I'm gonna be doing up I'm gonna be doing a really cool experiment Um of my own during the eclipse, uh, where I'm going to be wearing a green shirt And there's something called the I believe it's called the perk in g effect. Um, which is a Psychological it's it's an it's an effect with the color and photoreceptors of your eyes During the eclipse that when it darkens Reds become darker and duller and greens and blues become brighter and more vibrant Um, so tomorrow I'm going to be wearing a green shirt in order to see if my shirt becomes more Vibrant, um in the Shadow of the moon if I luck out to get the shadow of the moon. Um Because again, there's lots of clouds. I'm going to be in northern texas, which is looking actually good Um now the weather's not looking too weather's looking manageable And I do want to remind people too that even if there is weather happening where you're at in the path of totality It's still going to become night for a couple minutes Like it's not like you're going to be like, oh man, and then just go inside and like nothing happens. No Stay outside. I missed it Look at look at everything get dark around you for a couple minutes feel the temperature drop Depending how high the clouds are you might even be able to see if you have good visibility Like the edge of the shadow as it moves across the cloud surface All right Yes I may even make an argument seeing that is cooler than seeing the actual Eclipse itself because you get to see this huge shadow like drift across the earth's surface like mark two Which is you paint us in quick I I was just saying uh last night some co-workers that uh that were I meant to be out in texas Most of the clouds that are predicted are to be high clouds which high clouds The view can punch through high clouds It's really low clouds that you have to worry about even with low clouds You will still get sudden night for a couple minutes But with high clouds you can still punch through and you can still see it very easily And if there are high clouds it should even with a very thin layer of high clouds It still should allow us to see the shadow come through and I'm really I don't want clouds But the same time if there are high clouds tomorrow as they are predicted in the part of texas i'll be in I will see about maybe recording That really one of the things that I always recommend to people for eclipses too Is that if this is your first eclipse don't record it Don't take a camera with you Stand there and enjoy it Just take it in because there's going to be in a case of something like this There's probably going to be a million people with dslr's and mirrorless cameras That are going to be getting a way better photo than you can ever dream of So don't even sweat it Maybe take one with you that's in 2017. I did that. I took like a quick one with my phone And then just put my phone down and I just sat back and enjoyed it And I'm going to do the exact same thing for this one. I'm not taking the camera with me I'm just going to snap a photo with my phone Maybe take a video to show the shadow approaching but once totality comes quick photo put it down all good So enjoy it live in it if you're if you're not a follower of smarter every day They did a fantastic video on some of the things that you can look for during the eclipse From temperature changes to color changes to weird shadows Very highly suggest you check that out And and Dave Avery has a point a pinhole has no focal focal length but the distance from the pinhole to What it's projecting on determine is not only the image size but the blurriness of the edges Very very cool And uh, so I think uh sarunas has uh all of us beat Here we're just speaking of the moon shadow last year. I got to capture it from a satellite in space That is absolutely awesome. Nice So I I don't want to give it too much away But if you're not in the path of the eclipse and you would like to see the shadow move Live across the earth's surface from geostationary orbit Wink wink. I might have a place for you to to to watch from tomorrow Now where would that be? Where is that Ryan? Uh youtube.com forward slash at nasa spaceflight You go live at uh, I I looked it up to remember it and then I forgot again a 1630 universal So minus four for eastern minus six for central Minus five central. Sorry. They're like time. I'm getting confused minus minus seven for pacific so represent so Yeah, I I think then the the like go go out and see this because I think the next uh solar eclipse in the in the united states at least is in 2044 2045 correct. Yes, it will be 20 years from from now. So Um, I believe they're supposed to be one in alaska in the 2030s, but it's going to be like in march Which is not and that's like ask her who knows wants to go to alaska. It's miles away and it's cold Okay, you'll be going to an ask her. Um, okay. Okay, fine. I would drive to it honestly incorrect opinion. I'll put my hands up That would be a great road trip Yeah, dada, I think I think I have an idea for what we should do in in 12 years So and there's a tweet here as well from from the armstrong air and space museum, which I Shared in the nsf discord area because I thought it's very funny Uh, and they're in ohio the armstrong air and space museum. They tweeted update in case of inclement weather for viewing the eclipse the museum has set an alternate rain date for monday september 14th 2099 mark your calendar And I thought that was brilliant Nicely done. Yeah, uh, I think for us here in los angeles the next eclipse with the path of totality that crosses us sometime in the 3000s. So, um We're gonna have to wait a little bit. So go if you can go. I don't care where you are in the world If it's somewhere near if you are near the path of totality if you are within a reasonable travel distance of Two to three days to the path of totality go If you don't you're missing out. I could explain what it's like to you But I can't it's just it it transcends It transcends my ability to make words work correctly. I guess I would say it so there's there You have to be there. You gotta be there to see it So anyway speaking of being there to see it I gotta get going so I could do that and I think I think we pretty much hit the edge of this episode anyhow with that So I want to thank all of you who helped make the shows of tomorrow possible. Did you know That it literally takes it's as little as 99 cents a month to become a member of tomorrow Now some of the cool things that you get to do as a member of tomorrow you get access to our members only after show Which if you've just become a member congratulations, we're not doing one this week because I'm bailing I'm getting out of here So Dutta and ryan, I don't know if y'all are sticking around but if you do great No no after show today. Yeah, no after show this week We're very sorry, but it's one of those things where even if you like signed up right now You're getting in the after show and if you're one of these folks are escape velocity members You'd get access to our escape velocity channel in our discord server Where we've got a whole bunch of dad jokes and a whole bunch of other really funny things You basically get to see us coordinate do the logistics Talk directly to us basically We talk about cool stuff in there that we may not necessarily talk about public side With things there so feel free and then of course our discord server is just free to join as well jump in and say hello and have a good time and Again, thank you all so much if you'd like so you can head to youtube.com slash t m r o slash join boy It's been a while since I've posted and I forgot that there are quite a lot of things that have to happen in order to make that work But I want to thank everyone on the show today ryan Thank you so much for all the contributions today and in the past and in the future as well And I'm looking forward To y'all's broadcast tomorrow because I will go ahead. I will be watching it while I'm on the road Freaking out in texas trying to figure out how to get away from the clouds We'll have weather updates, which will be useful for you weather update. Yes. Thank you. Yeah, thank you One of the people I'm going with is a national Other service spotter So I'm I'm pretty excited about the fact that we have a actual weather person in our crew of four With this so But we'll take anything we'll take any data we can get Just wanted to be noted that if you do join tomorrow now You can fill up your waiting time for the eclipse with all of our past member shows that you previously weren't able to see And it's some space nerdery while you're waiting Yes, definitely. All right. Well everybody. Thank you so much We'll definitely be back next week We'll have an eclipse to talk about some of the maybe some preliminary science because the asshole We fly in some aircraft in the shadow of the moon Doing some ground science and even some science from space that I'll tell you about as well And of course, we'll probably have more spacex news because we don't need so that's kind of just how it goes Yeah, well, that's a report that they turn to bolt at starbase. All right, everybody. See you later Have a good one Don't look directly at the sun
