WEBVTT - Space Junk, Space Walks, Space Rescues + Helmet Drowning 0:00:03.680 --> 0:00:11.760 Now now, hello everybody. I'm Jason Alexanders, I'm Peter Told 0:00:11.960 --> 0:00:14.200 and today I'm really no, really, we're going to go. 0:00:14.720 --> 0:00:17.240 We're no. Man, it's gone before. Actually a lot of 0:00:17.239 --> 0:00:19.400 men and women have actually gone. And there's a lot 0:00:19.400 --> 0:00:23.880 of stuff. Because today we're talking about Peter space and 0:00:23.920 --> 0:00:27.480 the question is this space junk became an issue? Yeah, 0:00:27.520 --> 0:00:29.800 and I'm reading how much space drink. There are millions 0:00:29.800 --> 0:00:31.560 and millions of pieces of pace drunk up there. And 0:00:31.600 --> 0:00:35.320 what we're not talking like the Chinese balloon that came 0:00:35.360 --> 0:00:39.120 by golf ball size, big pieces, larger pieces, right, stuff 0:00:39.159 --> 0:00:42.480 that's been look at Tesla is up there. So we've 0:00:42.479 --> 0:00:45.839 been cocking up. We did the oceans, we do everything. 0:00:45.880 --> 0:00:48.120 We have to ship our stuff to China, everything, and 0:00:48.159 --> 0:00:51.320 they said no moss, not not not language. Um. But 0:00:51.400 --> 0:00:53.840 then I realized with all of the stuff that's going 0:00:53.920 --> 0:00:56.720 up there, my take, yeah, is we're gonna be landlocked. 0:00:56.760 --> 0:00:59.120 There's so much stuff up there. And there's something called 0:00:59.760 --> 0:01:02.279 I think it is the Kessler effect. Is that very 0:01:02.840 --> 0:01:05.479 I think that's what it is. Where on the ground. Yeah, 0:01:05.520 --> 0:01:10.160 if junk is just junk, okay, in space, junk hits 0:01:10.160 --> 0:01:13.960 other junk, creating more junk, so it keeps exponentially that 0:01:14.200 --> 0:01:15.960 you were going to do the coln routine for a minute, 0:01:15.959 --> 0:01:19.920 where here it's junk up there it's stuff. It is stuff. 0:01:20.560 --> 0:01:23.120 But when space junk hits other space drunk, it breaks 0:01:23.120 --> 0:01:25.920 apart and becomes more space and more space drunk, and 0:01:25.959 --> 0:01:28.720 I forget. It's a problem that compounds, is what you're saying. Yeah, 0:01:28.760 --> 0:01:32.200 and it's going seventeen thousand miles an hour. Well that's 0:01:32.520 --> 0:01:35.280 that's a nice rate. So my take is we're gonna 0:01:35.280 --> 0:01:38.360 be landlocked. Your take on space drunk, we'll fix it everything. 0:01:38.720 --> 0:01:42.919 There's no problem we can't fix. Really, yeah, no, really really, 0:01:43.280 --> 0:01:46.280 So who do you get to talk about space drunk? 0:01:47.319 --> 0:01:50.680 I'm always suspect because when I see spacewalks, Yeah, if 0:01:50.720 --> 0:01:53.200 there's that much space junk, are they either shooting it 0:01:53.280 --> 0:01:56.120 from an angle where they're hiding it or shouldn't deny 0:01:56.200 --> 0:01:59.400 doing a spacewalk, be diving and chucking to the side 0:01:59.400 --> 0:02:01.360 and doing all maneuvers to get out of the way. 0:02:01.440 --> 0:02:03.400 Right and by the way, the spacewalks we're busy. If 0:02:03.440 --> 0:02:04.960 you could spit speed it up a little bit. I'm 0:02:04.960 --> 0:02:07.560 going for the wrench. I'm bending down a lot of time. 0:02:07.600 --> 0:02:10.320 It takes a lot of time speed up. Who wouldn't 0:02:10.320 --> 0:02:12.720 know we are about do we naturally slow down and 0:02:12.760 --> 0:02:14.480 out of space? Because let me tell you, if I'm 0:02:14.520 --> 0:02:17.480 on a spacewalk, gonna go very fast. We'll be in 0:02:17.520 --> 0:02:20.919 and out and back in fast. You can say, jimminy cricket. 0:02:21.000 --> 0:02:23.440 Guess who we got. I'm really excited about this. We 0:02:23.560 --> 0:02:25.680 got somebody who can't talk about space junk and who's 0:02:25.680 --> 0:02:27.960 been up there and done I think he did two spacewalks. 0:02:28.000 --> 0:02:30.960 His name is Garrett Reisman. He's a mechanical engineer and 0:02:31.000 --> 0:02:34.840 a former NASA astronaut who's been up on the space station. 0:02:34.880 --> 0:02:37.320 I think a couple of times and did my right, Garrett, 0:02:37.440 --> 0:02:39.080 we're gonna start with junk, but you've been up there 0:02:39.120 --> 0:02:41.400 three times. But I read that you did two spacewalks. 0:02:41.880 --> 0:02:44.560 And the two spacewalks the thing that got me it 0:02:44.639 --> 0:02:48.480 said over the course of fourteen hours. That's how long 0:02:48.560 --> 0:02:51.640 they take. Well, first of all, thank you very much 0:02:51.680 --> 0:02:55.160 for having me on. It's great to see. Yeah, so um, 0:02:55.200 --> 0:02:58.079 I did actually three spacewalks, you know, not that I'm 0:02:58.120 --> 0:03:02.320 counting up. Thank you in the research. Thank you beautiful, 0:03:02.639 --> 0:03:06.760 nice job, and they didn't make a big deal. So 0:03:06.840 --> 0:03:09.200 big three three space walks fourteen hours. You want to 0:03:09.240 --> 0:03:11.160 change your assessment of how long were the three space 0:03:11.200 --> 0:03:14.200 walk fourteen hours each? Each one was about seven and 0:03:14.200 --> 0:03:16.040 a half a little bit over seven and a half hour, 0:03:16.639 --> 0:03:21.000 really yeah, and so yeah, so in total over twenty 0:03:21.040 --> 0:03:23.760 two hours. So let me it's so space drunk space? 0:03:23.880 --> 0:03:26.480 Are you worried you're going out there? Man? You're tethered. 0:03:26.520 --> 0:03:28.520 You're tethered and they got all the things to hold onto. Yea, 0:03:30.280 --> 0:03:35.640 what do I say, Reisman? You know? Is it Reeseman? 0:03:35.720 --> 0:03:38.840 I wasn't gonna say anything. You know, you say potato, 0:03:38.880 --> 0:03:42.480 I say potato, You say cardiovascular disease. Space want Giggenheim. 0:03:42.720 --> 0:03:48.200 Make sure that Peter did the name wrong. Peter, Peter 0:03:48.320 --> 0:03:50.920 got the number of spacewalks wrong. Just start a list. 0:03:51.200 --> 0:03:54.240 Peter said stuff is moving at seventeen thousand miles an hour. 0:03:54.360 --> 0:03:58.280 I don't think that's true. I think everybody calls me Reisman, actually, 0:03:58.360 --> 0:04:01.000 because I think now you're gonna my Peter got partial 0:04:01.040 --> 0:04:03.680 credit on the name. Were you were up there? One 0:04:03.760 --> 0:04:05.800 hundred and seven day, one hundred seven days, one hundred 0:04:05.840 --> 0:04:09.120 seven days, three hours and fifteen minutes. That could be right, 0:04:09.160 --> 0:04:13.040 I don't know. I days three hours, it's right. I mean, no, 0:04:13.120 --> 0:04:15.240 you're geting. But like these crazy nerds that like hang 0:04:15.280 --> 0:04:17.159 out with these like stop watches and time it to 0:04:17.200 --> 0:04:20.200 the second. But one hundred and seven days, one business, 0:04:20.400 --> 0:04:22.920 one piece. Never correct me, Laurie, I will say his 0:04:23.080 --> 0:04:25.520 name wrong. No one will. No, no, don't ever correct me. 0:04:25.800 --> 0:04:28.960 How dare you Reeseman Reisman? Who cares? He's a he's 0:04:28.960 --> 0:04:31.200 an astronaut. I got that right, Yeah, I was going 0:04:31.200 --> 0:04:35.839 with it whatever. See what you learn on the space 0:04:35.880 --> 0:04:38.039 station in close quarters is just go with it. You 0:04:38.040 --> 0:04:41.400 don't stress out over sure, right it is Garrett, right, 0:04:41.480 --> 0:04:44.039 that's okay. Yeah, although when something goes wrong, you go, 0:04:44.160 --> 0:04:47.279 where's Reeseman? And there's an Yeah right, he's just floating 0:04:47.320 --> 0:04:50.400 around over there. I come back, So it's actually gay. 0:04:50.480 --> 0:04:52.599 But I wasn't gonna say anything. So this is as 0:04:52.600 --> 0:04:54.480 fascinating as all this is, and I don't want to 0:04:54.520 --> 0:04:58.359 cut it short. Oh my god, space drunk. Why aren't 0:04:58.360 --> 0:05:00.960 we seeing you dive? And how what's the risk when 0:05:01.000 --> 0:05:02.320 you go out there? You know it's out there and 0:05:02.360 --> 0:05:05.040 it's flying. Yeah, so no, it is a huge risk. 0:05:05.080 --> 0:05:07.080 It's a big, big And how fast is it going? Here? 0:05:07.480 --> 0:05:12.320 About seventeen thousand, five hundred thousand, that's different, not seventeen 0:05:12.400 --> 0:05:16.839 thousand and seventeen your orbit. It could be going faster 0:05:17.000 --> 0:05:19.440 if it's coming from Look, you could have just said seventeen. 0:05:19.440 --> 0:05:20.880 You didn't have to add, you could have gotten his 0:05:20.960 --> 0:05:25.880 name rights. So okay, let's get serious space. So you're 0:05:25.880 --> 0:05:29.040 about to go out. It's really dangerous. Yeah it is. Yeah, 0:05:29.080 --> 0:05:31.440 it going out and doing the spacewalk is just as 0:05:31.560 --> 0:05:36.040 dangerous statistically as launching or entering. And we've lost people, 0:05:36.200 --> 0:05:40.480 you know, Challenger launching, Columbia entrink. Fortunately I got I 0:05:40.520 --> 0:05:43.120 need some wood to knock on here, but m Fortunately 0:05:43.000 --> 0:05:45.560 we haven't had any problem in space walking. But but 0:05:45.680 --> 0:05:48.640 statistically it's just as much risk. So what're about the space? 0:05:48.920 --> 0:05:51.040 So this episode is about how much space drunk is 0:05:51.120 --> 0:05:53.080 up there and how much it is predicted that will 0:05:53.120 --> 0:05:55.240 be up there in this world. Let's take it with 0:05:55.320 --> 0:05:58.040 you man, what is the boy Scout logo? It's a 0:05:58.160 --> 0:06:00.720 takeaway a picture leave only foot prints. Isn't that where 0:06:00.720 --> 0:06:02.520 you're supposed to do? Yeah, but we've been cluttering up, 0:06:02.560 --> 0:06:04.800 we've been messing that up for a while. We've been 0:06:05.040 --> 0:06:08.400 leaving all kinds of junk up there and in certain orbits, 0:06:08.520 --> 0:06:11.400 especially low orbits where the space station is, where the 0:06:11.400 --> 0:06:13.360 Space Shuttle used to fly and where we send a 0:06:13.440 --> 0:06:16.839 dragon spacecraft. That's where that's where most of our junk 0:06:16.920 --> 0:06:18.640 is because that's where we've spent most of our time. 0:06:18.880 --> 0:06:21.719 There's also a bunch of junk up at the geostationary 0:06:21.800 --> 0:06:24.440 love which is much higher, filling that too. That's and 0:06:24.600 --> 0:06:26.920 is that where the space station orbits or is the station? 0:06:26.920 --> 0:06:29.400 Space station is lower? It's lower and lower. Yeah, space 0:06:30.720 --> 0:06:33.080 it's between sort of the two most dangerous zones. Is 0:06:33.080 --> 0:06:35.520 that what you're saying? It's actually right in the middle 0:06:35.520 --> 0:06:38.160 of one of the most dangerous cells. Yeah, but it's 0:06:38.160 --> 0:06:41.360 about two hundred and twenty seven also up, is it? Yeah? Yeah, 0:06:41.360 --> 0:06:44.320 that's right. That's all very good, Peter, between two hundred 0:06:44.360 --> 0:06:46.320 and eighty and four hundred and I heard I've read 0:06:46.320 --> 0:06:48.640 that the space stations had to do maneuvers because, yes, 0:06:48.920 --> 0:06:51.440 because of Russian junk and other junk clouds that have 0:06:51.520 --> 0:06:53.200 gone by, So why not the space walk back to 0:06:53.320 --> 0:06:55.919 space walk? Are you looking for that stuff? Or it's 0:06:56.160 --> 0:06:58.200 the thing is like you guys saw the movie Gravity, 0:06:59.080 --> 0:07:02.160 I was gonna reference and because if I had seen it, 0:07:02.279 --> 0:07:04.680 let me tell you the us end off my spacewalk. 0:07:05.520 --> 0:07:08.599 You know, we got like a recruiting took a dip 0:07:08.680 --> 0:07:10.640 after that movie come out. In that movie, they can 0:07:10.680 --> 0:07:13.200 like see it coming like, oh look therery here it comes. Yeah, 0:07:13.280 --> 0:07:17.680 And that's ridiculous, That's that's bullshit, because the thing seventeen 0:07:17.720 --> 0:07:21.560 thousand and five family, sugar, Oh no longer in space. 0:07:21.600 --> 0:07:24.280 You're on ground. You're yeah, it's you can say it, 0:07:24.280 --> 0:07:28.080 we'll bleep. And I'm just saying, just saying, don't freaking curse, okay, 0:07:28.280 --> 0:07:31.520 just because you're in space three times no, so you 0:07:31.560 --> 0:07:34.880 cannot see it coming when you're the particles are that small. 0:07:34.920 --> 0:07:38.280 So seventeen thousand, five hundred that's our orbital velocity. That 0:07:38.400 --> 0:07:41.120 is about ten times faster than a rifle bullet. And 0:07:41.160 --> 0:07:43.080 you can't see a rifle bullet coming at you, right, 0:07:43.160 --> 0:07:45.360 it's invisible. So it's gonna be the same way with 0:07:45.400 --> 0:07:50.360 the space. But wait, wait, what are there pieces of 0:07:50.440 --> 0:07:53.360 things up there? Like I'm I was not kidding. I mean, 0:07:53.440 --> 0:07:56.800 you know, Musk did put a tesla up. There are 0:07:56.840 --> 0:08:02.120 there pieces that are that big or or similar, and 0:08:02.200 --> 0:08:05.040 you would see that, wouldn't you. You could potentially, but 0:08:05.080 --> 0:08:09.280 even that's but so you won't necessarily see it with 0:08:09.320 --> 0:08:12.040 your naked eye, but we can see it using sensors. 0:08:12.400 --> 0:08:14.600 So we have a lot of the Department of Defense 0:08:14.760 --> 0:08:18.080 looks up there for everything, and they could track anything 0:08:18.120 --> 0:08:20.880 down to like a couple of centimeters, so anything that's 0:08:20.880 --> 0:08:23.560 bigger than like a golf ball, they could track that, 0:08:23.640 --> 0:08:25.679 and they and that's what we move the space station 0:08:25.720 --> 0:08:28.640 periodically to get out of the way. Smaller stuff, though, 0:08:28.680 --> 0:08:30.800 is what you really worry about because that's hard to see, 0:08:31.400 --> 0:08:34.160 and for that we just rely on shielding. So the 0:08:34.240 --> 0:08:37.199 space station is covered with shields. They're called whipple shields 0:08:37.200 --> 0:08:39.600 because they're kind of like sandwiches. They got like a 0:08:39.640 --> 0:08:43.160 standoff piece of metal and then a shield lower down. 0:08:43.920 --> 0:08:46.760 And the stuff is coming so fast that you're not 0:08:46.800 --> 0:08:48.760 going to stop it with with a thin piece of metal, 0:08:49.120 --> 0:08:51.199 but you'll break it up into lots of little tiny 0:08:51.200 --> 0:08:52.920 pieces and then it kind of hits like rain on 0:08:52.960 --> 0:08:55.240 the hull if you if you put if you do that, 0:08:55.600 --> 0:08:57.240 So that's what we use on the space station, but 0:08:57.280 --> 0:08:59.560 you can't like put that on your space suit. So 0:08:59.559 --> 0:09:01.320 when you go there and doing the spacewalk, you're just 0:09:01.320 --> 0:09:04.760 playing the odds basically, So what's the plan. Let's stay 0:09:04.800 --> 0:09:06.080 in space junk for a little bit, then we can 0:09:06.120 --> 0:09:08.480 do your experience on the space station as an astronaut. 0:09:09.200 --> 0:09:11.959 What is a plan? Since we know what's incrementally increasing? 0:09:11.960 --> 0:09:14.000 And I was right with space dunk creates or the 0:09:14.080 --> 0:09:16.880 space junk, because as you said, if you get an 0:09:16.880 --> 0:09:19.280 impact and it breaks it and the shield breaks it 0:09:19.280 --> 0:09:21.840 into more pieces, that's just more junk, right, Yes, it 0:09:21.840 --> 0:09:24.120 doesn't stop the speed of that. That just bounces off 0:09:24.120 --> 0:09:27.640 and keeps going exactly, It keeps moving. And so the 0:09:27.679 --> 0:09:32.000 worst generators of this junk are when things either explode, 0:09:32.040 --> 0:09:35.320 so we have pressurized like old upper stages of rockets 0:09:35.320 --> 0:09:37.800 and things that get hot and then they burst apart 0:09:38.120 --> 0:09:40.920 and create lots of little pieces. What's even worse than 0:09:40.920 --> 0:09:43.240 that is when two satellites hit each other. And that's happened. 0:09:43.679 --> 0:09:46.199 It's rare, it's a big sky, but sometimes they actually 0:09:46.240 --> 0:09:48.640 can hit each other and if they collide then boom. 0:09:48.679 --> 0:09:52.400 That's even worse. And then the worst still, the very 0:09:52.440 --> 0:09:56.959 worst producer of this junk our anti satellite weapon tests. 0:09:57.679 --> 0:10:00.760 So We've done it a long time ago. The Russians 0:10:00.760 --> 0:10:03.840 have done it recently, the Chinese have done it fairly recently. 0:10:04.320 --> 0:10:06.280 So when they do that and they shoot a missle 0:10:06.320 --> 0:10:08.760 it when these satellites, then it creates thousands of pieces 0:10:09.200 --> 0:10:11.120 and depending on the orbit it could be it could 0:10:11.120 --> 0:10:13.720 really persistent stay up there. The higher it is, the 0:10:13.840 --> 0:10:16.680 longer it's going to last because there's nothing. You know, 0:10:16.720 --> 0:10:19.480 what goes up comes down if there's air, but if 0:10:19.520 --> 0:10:22.640 it's an orbit, it will stay there for a long 0:10:22.720 --> 0:10:29.240 time before. So you've said we've done it, China's done 0:10:29.240 --> 0:10:31.160 at Russia has done it. Is there any sort of 0:10:31.679 --> 0:10:34.360 standing or prevailing treaty that says, let's not do that 0:10:34.400 --> 0:10:37.080 for our mutual interest anymore? Or is that still it's 0:10:37.200 --> 0:10:39.880 kind of doing it. It's every time somebody does it, 0:10:39.920 --> 0:10:43.240 there's a lot of finger wagon. There's no treaty that 0:10:43.320 --> 0:10:46.360 says like you've violated a law or a resolution or something. 0:10:46.360 --> 0:10:48.840 But there were there should be. There were international laws 0:10:48.880 --> 0:10:51.800 that said you're supposed to within five years clean it up. 0:10:52.280 --> 0:10:54.120 And I don't think anybody's racing to do that. And 0:10:54.160 --> 0:10:57.400 I'm envisioning with the technology we have, making like a 0:10:57.440 --> 0:11:01.920 gigantic blue hinged receptacle and a green one in the block. 0:11:02.200 --> 0:11:04.400 You shoot them up, you open the hinge, and then 0:11:04.400 --> 0:11:06.400 every Tuesday you have somebody come up and pick them up. 0:11:06.520 --> 0:11:09.200 The hard part is, you know, sorting it. So you 0:11:09.200 --> 0:11:12.200 gotta figure out is this compost or is this? You know? 0:11:12.800 --> 0:11:15.720 Is there? You gotta look at the number one, so 0:11:15.880 --> 0:11:17.599 do they have it? Have you heard of you you 0:11:17.960 --> 0:11:20.600 were NASA, you would know is there a plan? The 0:11:20.640 --> 0:11:22.800 best thing we could do is not make any more 0:11:22.800 --> 0:11:25.280 of this stuff. So what we do now that's different 0:11:25.800 --> 0:11:28.240 is we used to have these upper stages that would 0:11:28.280 --> 0:11:31.240 deliver say a capsule or a satellite up to up 0:11:31.240 --> 0:11:33.719 to orbit and and then we would just leave it 0:11:33.800 --> 0:11:35.560 up there and it would be an orbit itself until 0:11:35.600 --> 0:11:38.560 it eventually it might break apart. So what we do 0:11:38.600 --> 0:11:40.120 now is we keep a little tiny bit of gas 0:11:40.120 --> 0:11:42.199 in the tank and we burn the engine one more 0:11:42.240 --> 0:11:44.600 time so it comes down in one big piece, so 0:11:44.600 --> 0:11:47.400 we don't make any more junk. So that's one thing 0:11:47.400 --> 0:11:51.120 we could do to not make it worse. So you you, you, 0:11:51.120 --> 0:11:53.840 you you fire that engine to make it come down. 0:11:53.920 --> 0:11:56.920 Why wouldn't you fire the engine to send it out? Well, 0:11:56.960 --> 0:11:59.960 you know that takes a lot more gas, so it 0:11:59.640 --> 0:12:02.560 would it would you only have you use up almost 0:12:02.559 --> 0:12:04.600 all your gas. You keep a little bit of extra 0:12:04.720 --> 0:12:06.880 just in case, but when you get up to orbit, 0:12:06.920 --> 0:12:08.600 you have just a little bit left and not enough 0:12:08.640 --> 0:12:10.600 to leave Earth. At that point you'd have to have 0:12:10.640 --> 0:12:12.280 a lot more to like go to the Moon or 0:12:12.400 --> 0:12:14.560 to Mars or whatever. So you only have a little 0:12:14.600 --> 0:12:16.560 bit left, but it's enough to slow you down, so 0:12:16.640 --> 0:12:18.559 that Earth pulls you back and you'd burn up in 0:12:18.600 --> 0:12:20.480 the atmosphere. It sounds like how my mother used to 0:12:20.520 --> 0:12:26.080 keep gas in their car fast enough I can't get 0:12:26.120 --> 0:12:28.280 where I'm going, but she's got just enough to make 0:12:28.280 --> 0:12:31.000 it up the driveway. So before we leave space Junk, 0:12:31.400 --> 0:12:33.440 I've made an observation and maybe you can help me 0:12:33.480 --> 0:12:37.240 with this. Yeah, the space to Earth economy is huge 0:12:37.240 --> 0:12:39.400 in space to Earth, meaning you guys do testing all 0:12:39.400 --> 0:12:42.439 the time to benefit us you're on Earth. All of 0:12:42.480 --> 0:12:46.479 a sudden, the paradigm has shifted to space to space economy, 0:12:46.880 --> 0:12:50.439 where they're spending more and more. There's privatization, there's SpaceX, 0:12:50.520 --> 0:12:53.920 there's Amazon thing. It's putting a lot more in space. 0:12:54.559 --> 0:12:56.760 Is it because he's wealthy? Guys? Know they ain't gonna 0:12:56.760 --> 0:12:58.120 be getting it will get out in a while. So 0:12:58.360 --> 0:13:00.280 we're racing to get that Moon colony and to get 0:13:00.320 --> 0:13:02.280 the Mars because they know something we don't know that 0:13:02.360 --> 0:13:04.800 we're gonna be landlocked now. So I used to work 0:13:04.800 --> 0:13:07.800 for Elon Musk, right, and I can tell you that's 0:13:07.840 --> 0:13:09.920 never been a topic of conversations. I've got to hurry 0:13:10.040 --> 0:13:14.199 up before. Like if you remember Wally when like it's 0:13:14.200 --> 0:13:16.800 so literally they could barely get it doesn't really work 0:13:16.840 --> 0:13:19.440 that way. Um, you can avoid this stuff, and if 0:13:19.440 --> 0:13:22.280 you're just passing through the odds of hitting something are 0:13:22.400 --> 0:13:25.640 very very small in ten years, even even even if 0:13:25.640 --> 0:13:28.000 it gets worse if you're just passing through. The danger 0:13:28.120 --> 0:13:30.240 is when you hang out up there. So right now, 0:13:30.320 --> 0:13:32.199 it's a big concern for the space station, which is 0:13:32.200 --> 0:13:35.160 there all the time. And so the biggest risk over 0:13:35.280 --> 0:13:37.680 like any six month period that you're gonna send a 0:13:37.760 --> 0:13:40.240 crew up there, is getting hit by one of these things. 0:13:40.280 --> 0:13:42.240 It's actually the most the biggest thing we worry about, 0:13:42.400 --> 0:13:44.679 right Wow, But if you're just passing through on your 0:13:44.679 --> 0:13:46.800 way to the Moon, you're kind of okay. Yeah, So 0:13:46.880 --> 0:13:49.840 let's switch to the space station because knowing you were 0:13:49.840 --> 0:13:52.320 coming in and blew me away. I thought about it 0:13:52.320 --> 0:13:53.839 because I hear about it, and you guys wave and 0:13:53.840 --> 0:13:56.200 you sing songs, and the pizzas delivered and all that stuff. 0:13:56.600 --> 0:14:00.480 But I didn't realize they didn't share with you, these 0:14:00.480 --> 0:14:02.800 astronauts these days that, by the way, dominoes in thirty 0:14:02.840 --> 0:14:05.840 minutes or it's free. You know, honestly, I made a 0:14:05.840 --> 0:14:08.160 whole bunch of calls. Yeah, because you have a phone 0:14:08.240 --> 0:14:10.440 up there. Oh and I call it seriously, did that? 0:14:10.480 --> 0:14:12.520 I called a couple of places a guarantee thirty minutes 0:14:12.600 --> 0:14:17.440 or less. Oh fantastic. Technically, at let's addressed that interesting 0:14:17.480 --> 0:14:19.440 thing about the space station. You can make calls to 0:14:19.480 --> 0:14:21.600 your family. It clears a bellance and emails, right, no 0:14:21.640 --> 0:14:24.680 problem because you're right near the satellites. What I didn't realize, though, 0:14:24.800 --> 0:14:27.000 is that the thing is as long as a football field. 0:14:27.440 --> 0:14:29.560 They say it's the size of a six bedroom house. 0:14:29.680 --> 0:14:32.600 But when you think about that, verybody listening because there's 0:14:32.600 --> 0:14:35.160 no volume, you can't use the ceiling is the floor 0:14:35.160 --> 0:14:37.480 of the floor, the ceiling. It's like twenty times the 0:14:37.520 --> 0:14:39.840 size of a six bedroom, right, because in my house 0:14:39.840 --> 0:14:42.680 with the ten foot cathedral ceilings, but I can't do 0:14:42.760 --> 0:14:45.640 anything on any ceiling. It's wasted space. Look at all 0:14:45.640 --> 0:14:48.120 the space in this room right wasting right now. So 0:14:48.160 --> 0:14:51.440 when you're up there, Okay. The bigger issue for me 0:14:51.480 --> 0:14:54.360 that was really fascinating is the weight listing. I read 0:14:54.400 --> 0:14:57.360 a lot about astronauts describing it, and one astronaut said, 0:14:58.040 --> 0:15:00.480 it's almost like you're just a conscience flow because you 0:15:00.480 --> 0:15:03.040 don't feel anything. You don't feel your clothing, you don't 0:15:03.080 --> 0:15:06.440 feel the blanket at night. So it really kind of 0:15:06.480 --> 0:15:08.520 messages your head up a little bit as far as 0:15:08.640 --> 0:15:12.920 realigning where your body is at any given time. Yeah, 0:15:13.000 --> 0:15:14.840 you know, but if you go too fast and you 0:15:14.920 --> 0:15:18.560 knock your head into the hatch, it still hurts. I'm 0:15:18.560 --> 0:15:20.760 not sure about that. But before we leave the space chalk, 0:15:20.800 --> 0:15:22.680 there's one more thing I wanted to tell you, which 0:15:22.760 --> 0:15:25.680 is on my very first spacewalk, I went out there 0:15:25.800 --> 0:15:28.560 with this guy, ricklan Ahan, and we had this We 0:15:28.680 --> 0:15:30.880 out there for seven and a half hours. We did 0:15:30.920 --> 0:15:33.400 all of our work and we come back inside and 0:15:33.440 --> 0:15:34.800 one of the things we had to do is we 0:15:34.840 --> 0:15:36.960 had to bring inside this handle. We called it a 0:15:37.040 --> 0:15:39.640 d handle. It's just a big hunk of metal like 0:15:39.680 --> 0:15:42.480 a steering wheel that you could take off and put on, 0:15:42.560 --> 0:15:44.280 and so if you're gonna move something, you could put 0:15:44.320 --> 0:15:46.280 it on there. Now you have a handle to grab 0:15:46.320 --> 0:15:48.360 this thing by, right, And we needed it for a 0:15:48.400 --> 0:15:51.640 subsequent spacewalk for like a couple days later, so we 0:15:51.720 --> 0:15:53.560 had to bring it inside so that the next crew 0:15:53.600 --> 0:15:55.760 could go use it. So we carried the thing inside. 0:15:55.800 --> 0:15:59.520 It's made out of like half inch thick solid aluminum. 0:15:59.640 --> 0:16:01.560 He's looking at it in his hands and he sees 0:16:01.600 --> 0:16:05.240 that there's a hole shot straight through all the way 0:16:05.240 --> 0:16:08.240 through that aluminum. It's about like a millimeter. It looks 0:16:08.240 --> 0:16:12.240 like somebody took a cocktail straw and just like Superman 0:16:12.320 --> 0:16:14.960 and just like punched it through the aluminum and made 0:16:14.960 --> 0:16:17.880 a clear hole straight through. And he looked down at that, 0:16:17.960 --> 0:16:19.560 and he looked back up into me and he said, 0:16:19.560 --> 0:16:23.200 you know, man, if that hit one of us. And 0:16:23.240 --> 0:16:25.960 he didn't have to complete that sentence, right, because it's 0:16:25.960 --> 0:16:29.120 not that you worry about like losing pressure in your suit. 0:16:29.160 --> 0:16:30.760 If you get hit by one of those things and 0:16:30.880 --> 0:16:33.720 the air leaking out, you're in one hundred percent oxygen. 0:16:34.080 --> 0:16:36.520 So the moment something with that kind of energy punctures 0:16:36.520 --> 0:16:40.360 your suit. You flame up immediately, and it's flame up, 0:16:40.400 --> 0:16:42.880 flame up, as the phrase, it's not a good day. 0:16:43.000 --> 0:16:46.120 It's not like in a Fantastic four kind of way, 0:16:46.240 --> 0:16:50.560 but in a sort of painful flame. Okay. I also 0:16:50.640 --> 0:16:52.840 heard that if your suit rips, if your suit rips, 0:16:52.840 --> 0:16:55.440 which happened in the test, all right, that it's your 0:16:55.520 --> 0:16:58.680 lungs collapse. You don't explode, But also that the moisture 0:16:58.680 --> 0:17:01.240 in your tongue, your eyes, you're it starts to boil off. 0:17:01.320 --> 0:17:04.359 Is that correct? Yeah, it's called So what happens is 0:17:04.359 --> 0:17:08.160 if you're exposed a hard vacuum unless your Princess Leia 0:17:08.240 --> 0:17:11.720 and then apparently you can get away with it. But 0:17:11.800 --> 0:17:15.000 if you're not, then um, then what happens is all 0:17:15.080 --> 0:17:18.200 the liquids in your in your tissues begin to change phase. 0:17:18.280 --> 0:17:20.560 It's like they're boiling. It goes from liquid to gas. 0:17:21.240 --> 0:17:23.399 And it's kind of like Schwarzenegger on Total Recall with 0:17:23.600 --> 0:17:26.600 like their favorite their bulging eyes and all that. That's 0:17:26.680 --> 0:17:28.880 kind of what would happen. You would have this grotesque 0:17:29.040 --> 0:17:33.680 bulging and um edema and all the swelling. Anyway, that's 0:17:33.760 --> 0:17:37.000 that's me after Thanksgiving meals and by the way, I 0:17:37.000 --> 0:17:39.040 should mention because we talked about this before you went 0:17:39.080 --> 0:17:41.320 on the bonus of going up to the space station 0:17:41.520 --> 0:17:44.960 is all the all the food in your body goes up, correct? Yeah? Um, 0:17:45.280 --> 0:17:47.919 you also can't go to the bathroom become constipated. But 0:17:47.960 --> 0:17:50.879 you're two inches taller, yes, so, which which is the 0:17:50.920 --> 0:17:53.040 whole reason I signed up for this job. By the way, 0:17:53.920 --> 0:17:57.439 I'm not I'm not signing up there because, as you 0:17:57.480 --> 0:18:01.560 guys have probably noticed, I'm a little vertically challenged. And 0:18:01.840 --> 0:18:04.360 when when Rick was looking at that hole and said, oh, 0:18:04.359 --> 0:18:06.520 if this hit one of us, I pointed out that 0:18:06.600 --> 0:18:10.200 statistically it was much more likely to hit him, sure, 0:18:10.240 --> 0:18:13.280 because he's six foot four. Yes, right, And besides, I 0:18:13.320 --> 0:18:15.080 was like behind you most of the way, so I 0:18:15.119 --> 0:18:17.439 think I was pretty safe out there. You That's why 0:18:17.760 --> 0:18:19.760 that's why I've teamed up with Peter in case, in 0:18:19.760 --> 0:18:22.439 case we ever got retrimission for people to listening and 0:18:22.720 --> 0:18:25.200 not watchings on YouTube. Guards or about four four foot 0:18:25.200 --> 0:18:29.400 five Come on, okay, you're tall, you're mighty. I'm fine personal. Yeah, 0:18:29.400 --> 0:18:31.560 we're about to say ye five four, but wait, I 0:18:31.680 --> 0:18:33.719 want to go back to the spacewalk. So seven hours 0:18:34.080 --> 0:18:37.520 this is the first place my mind went, a I 0:18:37.600 --> 0:18:40.080 know where you're going. What happens if you need to 0:18:40.640 --> 0:18:45.800 go and be It's not like you can pop down 0:18:45.840 --> 0:18:49.680 an energy bar. You know, do you get hungry? I guess, 0:18:50.200 --> 0:18:52.520 I guess on the go sure diaper, you just go. Yeah, 0:18:52.760 --> 0:18:55.560 there you go, you just go. Yeah. I went like 0:18:55.680 --> 0:18:57.840 four times before they even opened a hatchet. Oh yeah, 0:18:58.280 --> 0:19:00.679 let me carol, and twice doing this whatever I went, 0:19:00.960 --> 0:19:05.960 I was gonna say, I went myself. That's how you look. 0:19:06.320 --> 0:19:09.960 And then you just kind of your carve up before. Yeah, 0:19:10.000 --> 0:19:11.960 your carve up before you go. And we used to 0:19:12.040 --> 0:19:14.240 have like a little kind of like a fruit roll 0:19:14.320 --> 0:19:16.840 up in the helmet that you can nibble on, but 0:19:17.040 --> 0:19:19.040 that got messy and it just it wasn't didn't really 0:19:19.080 --> 0:19:21.360 help very much. So we got rid of that water water. 0:19:21.560 --> 0:19:22.960 You have a you have a little you have a 0:19:23.000 --> 0:19:25.400
