Stuff You Should Know - Space Junk, Ahoy!

Episode Date: March 25, 2021

The orbits hundreds to thousands of miles above Earth are littered with garbage. Space garbage, sure, but it’s still garbage. Littering in space is bad enough but it poses practical problems too –... like space junk crashing into satellites or astronauts.

Starting point is 00:00:00 Hey, I'm Lance Bass, host of the new iHeart podcast Frosted Tips with Lance Bass. Do you ever think to yourself, what advice would Lance Bass and my favorite boy bands give me in this situation? If you do, you've come to the right place because I'm here to help. And a different hot sexy teen crush boy bander each week to guide you through life. Tell everybody, yeah, everybody about my new podcast and make sure to listen so we'll never, ever have to say bye, bye, bye. Listen to Frosted Tips with Lance Bass on the iHeart radio app, Apple podcast, or wherever you listen to podcasts. I'm Munga Chauticular and it turns out astrology is way more widespread than any of us want to
Starting point is 00:00:40 believe. You can find in Major League Baseball, International Banks, K-pop groups, even the White House. But just when I thought I had a handle on this subject, something completely unbelievable happened to me and my whole view on astrology changed. Whether you're a skeptic or a believer, give me a few minutes because I think your ideas are about to change too. Listen to Skyline Drive on the iHeart radio app, Apple podcast, or wherever you get your podcasts. Welcome to Stuff You Should Know, a production of iHeart Radio. Hey and welcome to the podcast. I'm Josh Astro Clark and there's Charles afterburn Bryant. Okay. And Jerry Goose Rowland is out there.
Starting point is 00:01:32 Wait, are you calling me afterburn because I'm gassy? Yep. Although we've been, we've been tooting for a year straight and no one even... No one knows except us. Have you ever set one of your ducks on fire? Have I ever lit a fart? I was hoping to not use that word but yes. Yes. Yeah, I used to, there was a period in my youth where I thought that was just about the funniest thing ever and I still think it's pretty hysterical. I just don't do it. I never thought it was funny. I've always just been more wowed by it, you know? It's, I mean the notion of it now as I've gotten older is more funny than the act itself.
Starting point is 00:02:09 Yeah, agreed. The notion that we can expel flammable cats from our butt. Exactly. It's pretty great. And then do you remember that cautionary tale that, that if you lit it, it could travel up into your rectum and cook your insides? Some sort of a reverse thing, yeah. There must have just been like some, I don't know, some department somewhere, some obscure federal agency that was tasked with coming up with fake cautionary tales to scare kids out of doing things that, that where they weren't behaving, you know? Yeah. And I think what my most cherished memories were the times where people swore that it wasn't
Starting point is 00:02:48 possible. That, oh, that you couldn't light it, that it wouldn't work? Yeah. So proving, proving that was always sort of the most fun because it was just like hilarity ensued. And also you just got to be like in your face. Like literally come down here because I'm going to light this in your face if you're just so sure it's not going to catch fire. And I always had a theory that it would get rid of the smell kind of instantaneously too. I think it just burned it up. I think it did. So it's really an efficient way of clearing the air. What are we doing? Well, we're talking Chuck about space junk. And actually that whole, that whole thing, what?
Starting point is 00:03:25 There's a, immediately he had to look it up because I was going to say great band name, but there's a band out of Buffalo named Spacejunk. Oh, yeah, out of Buffalo. Oh, I guess that, I guess that, that affords being mentioned. Sure. Sure. Okay. So Spacejunk, not the band, the actual stuff, stuff floating around in space. Yes. Turns out there's a lot of it. And I actually have a little bit of an intro here. I'm going to do a little, a little... Oh, it wasn't the, the toot lighting? No, that was a pre-show tangent. Okay. Okay. I think it's that classification. No, back in the 70s, there was a guy who
Starting point is 00:04:05 worked for NASA called Donald Kessler. And he was an interesting cat in and of himself. But one of the claims to fame that he has is that his name became synonymous with a, a, an unstoppable chain reaction of collisions of Spacejunk called the Kessler syndrome. And the Kessler syndrome that Kessler came up with is based on this idea that if you get enough stuff floating around, in orbit, around Earth, eventually this stuff is going to smash and do other stuff up there because these things are traveling at very high speeds. And when they smash in on another, they're going to potentially break into more and more pieces. And then those pieces are going to go on and they're going to smash into other things.
Starting point is 00:04:51 And so this chain reaction will begin to where there's just pieces constantly smashing into one another. And all of a sudden we're trapped on Earth because we can't make it through the debris field we accidentally created. Hence the Kessler syndrome has struck again, like a, like a fart being lit in your face, but in the face of humanity as a whole. Yeah. And I think some, some scientists these days say that parts of our orbit are already like that, right? Yeah. So Kessler was basically saying he made these predictions in the 70s. And he said, based at the rate that we're going, it'll probably we'll reach a critical mass or in about 30 to 40 years. And a lot of people said, well, we've reached that point. And I think
Starting point is 00:05:36 Kessler is actually right. The thing is, we can't really see everything that's up there. So we have to make guesses and assumptions. We actually track a very respectable amount of space junk considering that we're just down here on Earth that we actually can track things going really fast that are really small, traveling really far above the Earth. But there's a lot of it that's just too small for our current technology to track. So we have to make guesses about what all's up there. And it looks like there's a lot of stuff up there. And it's possible we have reached critical mass and this, this cascading collision, the chain reaction, it just hasn't started yet. Yeah. I mean, I was just about to correct myself when I said some people say it's already there.
Starting point is 00:06:18 That I didn't mean it's all just so people understand it's already like we can't travel through these places. But that process has started such that it can't be reversed. Like even if we stop launching anything, they're like, it's too late. Yeah. Once that chain reaction starts, I mean, there's nothing we can do about it. I mean, we can't even get a lot of the space junk that's up there out now. I can't imagine when they've started on a chain reaction that's got to make catching it even, even more difficult. So a lot of people say, well, let's do everything we can to avoid that cascading collision, that Kessler syndrome from ever starting. And a lot of people sitting out there, Chuck, I'm guessing are like, wait, what are you guys talking about with space
Starting point is 00:06:59 junk? What is the space junk? Yes, I'm well versed with the band from Buffalo. I have all of their CDs. I got them all for free. Just walking past this one street corner many times over multiple years. But I don't know about the actual space junk. And it never occurred to me that the band space junk is based on a real thing. Right. So space junk, I kind of always assumed people knew what this was, but we've made that assumption before about things like, I don't know, trees. And people said, why don't you describe what a tree is? Parrots. So, oh, by the way, thanks for all the parrot pictures from all over the world. Yeah, we've been. It's been delightful. Yeah. But space junk is, you know, it can be a lot of
Starting point is 00:07:42 things. NASA actually has a sort of a list that describes it better than we could. A lot of it is abandoned spacecraft or spacecraft that doesn't work anymore. So we abandon it. This can be big, full spaceships or it can be parts of spaceships because as we'll learn. And as you know, if you follow, you know, if you're a rocket enthusiast, like those things break apart and we'll get to that. But there are many pieces that are quite large that are just sort of left up there until they come back down or they hit something else. Yep. Some of this stuff is, like I said, parts of rockets that have broken apart, usually upper stage, because that lower stage stuff breaks off early enough to where it generally, you know, after a few years may tumble back toward Earth, burn up,
Starting point is 00:08:32 hopefully. So where nothing actually hits Earth, but that upper stage stuff is kind of stuck up there. Yeah. Yeah. That's one thing that you'll find out about things that we place into orbit. The further away from Earth that this thing is circling the Earth, the longer it's going to take to come back down to Earth. So that makes sense. Yeah. Because it's the force of gravity that pulls these things in orbit back down to Earth eventually, right? Yeah. What else do we have? Motor effluent? Yeah. So a lot of unspent fuel, a lot of rocket fuel is solid fuel. And that includes, I was looking it up, that includes ammonium nitrate appropriately enough. But it also, yeah, and enemy. But it also includes gunpowder, black gunpowder. That's what they use
Starting point is 00:09:20 as solid rocket fuel sometimes, which is like, we've come really far, but also not far at all, you know. So there's canisters of gunpowder floating around up in space, which are particularly problematic because not only can they break things apart, they can really break things apart, because they may explode when they impact things going as fast as they travel. And then the last thing, and we'll get to all the detail about all this stuff and why it's dangerous, but little bitty, little tiny things, little tiny flecks of paint even, and millions of them can cause a lot of damage. I think there is, you know, reports from astronauts that say, you know, that work on the Hubble that are like, this thing looks like a car that's been
Starting point is 00:10:02 through a hail storm, you know. It's just like getting constantly pelted. And you think a speck of paint, who cares? But when these things are going 20 something miles an hour, it can cause some damage. Yeah. I think his famous quote back to ground control was, this thing looks like a 72 Nova. They went, yeah, no kidding. It's the Hubble. Yeah. So when we, when we, the thing about space junk is that you have to remember is every single bit of it used to be here on Earth, and every single bit of it was launched by humans. That's just space junk. There's plenty of other stuff out in space, like asteroids and comets and pieces of rocks flying around. That's not space junk. Yeah. ETs flying around. That's not space junk. Space junk is specifically things that
Starting point is 00:10:48 humans have launched into Earth. So there's this whole kind of air of, oh, I don't know the actual word for it, but that we've done this to ourselves. Like we've created our own problem and now we've made this bed that we have to lie in or figure out how to get out of, I think. It's so human, isn't it? That like, let's destroy the Earth. Let's start destroying space because we may want to live up there. So we might as well pre-destroy it before we get up there to really destroy it. Right. And it makes sense though, early on in the space programs, starting in the, in 1957 with the launch of Sputnik. That's when the whole thing started. But it makes sense that that we had the technology to get things up there, but not to get them back down. And we knew that
Starting point is 00:11:38 eventually their orbit was going to decay. They would be pulled down into the atmosphere where it would probably burn up. So that made sense at the beginning of the space race. But as we got better and better at technology, the idea that we could just litter space became less and less acceptable. The problem is it didn't really go away. Like there's still basically stuff that's being launched up there today that has no way of being brought back down. It's just like, we'll just leave it up there until it runs out of its useful life and then hope for the best. That's kind of how a lot of stuff is being launched into space right now. And it's particularly galling because we have the technology to bring it back down. It just makes the whole thing more
Starting point is 00:12:23 expensive. And I think that that's why a lot of companies and countries don't include that. Yeah, there's a saying among contractors, a joke, if you will, among contractors who build houses and fix up houses. If there's something wrong and that they're working on and the homeowner isn't around, they just say, can't see it from my house. I've not heard of that. That's kind of what's been going on here for years with, I mean, not only space agencies, but private companies as we'll see, Amazon and Tesla and all kinds of companies have plans to put a lot more things into space. And it made me wonder, like, who's regulating this stuff? We'll get to all that. But what's kind of cool is since 1957, when Sputnik
Starting point is 00:13:13 was launched into space, NORAD started cataloging this stuff and numbering them and naming them. And Sputnik is object number one. And, you know, they do a really good job of keeping track of a lot of this stuff. Like you said, considering we're down here and it's up there, it's not too bad. Things started breaking apart, though, and getting smaller and colliding with one another, creating hundreds and thousands of more smaller bits. But we kind of, you know, our technology progressed where we could go smaller in our tracking abilities. And so now the U.S. Department of Defense started cataloging anything basically larger than, I think, a softball? I've seen grapefruit, too. So yeah, basically that size. If you're not familiar
Starting point is 00:13:58 with softballs, but you're crazy for citrus, it's grapefruit size, too. If you don't know either one of those, I'm sorry, that's the best we can do. Yeah. Maybe two of your fists balled up. Like a good, and I don't know how big your fists are. A good size snowball. Okay, sure. But somebody's like, but I'm from the tropics. I don't know any of this stuff. I'm from Buffalo. I know about snowballs and space junk. That's right. And that catalog, Chuck, by the way, is pretty awesome. It contains not just sputnik and all every satellite ever created and every grapefruit size piece of debris. But there's some other really interesting stuff in there, too. The cremated remains or the canister containing the cremated remains of Gene Roddenberry
Starting point is 00:14:42 is one of them. The Creator Star Trek. The Tesla Roadster that SpaceX launched is up there. I was mad about that one. Yeah. Especially when you start learning about space junk, you're like, this is not a good idea. Yeah. What we don't need to do is just do like PR stunts, launching stuff into space. Yeah. And then like astronauts have lost entire boxes of tools on spacewalks before. And they're just out there floating around, wrenches and stuff like that. They're all in the catalog. I thought they cut that stuff tethered. You gotta tether it. Yeah. Sometimes it gets loose or they forget to tether it. Astronauts, they have hard days, too. That's right. They have their
Starting point is 00:15:24 B game on some days. But yeah, anything as small as a softball, there are about 20,000 pieces orbiting the Earth right now. And then there are about half a million pieces the size of a marble or larger that NASA is tracking. And then the paintflex, just good luck with that. There's millions of that and no one keeps track of it. Yeah. And paintflex is, well, just because we can't, we definitely would if we could, but we just don't have the technology right now. Sure. Because there's, so there's three orbits. I don't want to do an episode on satellites one day, but just briefly, there's three orbits, low Earth orbit, middle Earth orbit, not to be confused with the Shire, and geosynchronous orbit, which is way up there. And that's where your
Starting point is 00:16:11 communication satellites are. They're geostationary. They basically, if you stand in a spot and could look up and there was a satellite ahead of you or above you, it'd be there 24 hours a day, every day of the year. It's moving in line with one spot around the Earth. And to do that, you have to be really far out. The stuff that's further closer to the Earth travels the fastest, and it seems that lower Earth orbit is the most crowded too. So the things that are in lower Earth orbit are traveling the fastest, and there's the most of them because it's the easiest to get to you. Right. I feel like that's a pretty good setup if you include our two lighting stories. Sure. So maybe we should take a break and talk a little bit about some of the things they're
Starting point is 00:16:56 doing to mitigate this right after this. Hey, I'm Lance Bass, host of the new iHeart podcast, Frosted Tips with Lance Bass. The hardest thing can be knowing who to turn to when questions arise or times get tough, or you're at the end of the road. Okay, I see what you're doing. Do you ever think to yourself, what advice would Lance Bass and my favorite boy bands give me in this situation? If you do, you've come to the right place because I'm here to help. This, I promise you. Oh, God. Seriously, I swear. And you won't have to send an SOS because I'll be there for you. Oh, man. And so my husband, Michael, um, hey, that's me. Yeah, we know that Michael and a different hot sexy teen crush boy band are each week to guide you through life step by step. Oh, not another
Starting point is 00:17:52 one. Kids, relationships, life in general can get messy. You may be thinking this is the story of my life. Just stop now. If so, tell everybody, yeah, everybody about my new podcast and make sure to listen so we'll never ever have to say bye, bye, bye. Listen to Frosted Tips with Lance Bass on the iHeart radio app, Apple podcast, or wherever you listen to podcasts. I'm Mangesh Atikler. And to be honest, I don't believe in astrology, but from the moment I was born, it's been a part of my life in India. It's like smoking. You might not smoke, but you're going to get secondhand astrology. And lately, I've been wondering if the universe has been trying to tell me to stop running and pay attention because maybe there is magic in the
Starting point is 00:18:37 stars if you're willing to look for it. So I rounded up some friends and we dove in and let me tell you, it got weird fast. Tantric curses, Major League Baseball teams, canceled marriages, K-pop. But just when I thought I had a handle on this sweet and curious show about astrology, my whole world came crashing down. Situation doesn't look good. There is risk to father. And my whole view on astrology, it changed. Whether you're a skeptic or a believer, I think your ideas are going to change, too. Listen to Skyline Drive and the iHeart Radio app, Apple Podcast, or wherever you get your podcasts. All right. So there's a lot of space junk out there. A lot of collisions happening
Starting point is 00:19:38 when satellites collide. Like I said, they can create just a very much bigger problem by creating lots more smaller pieces. And there are a few countries, the USA is one of them, China's one, India's one, that we have used missiles before. They're called anti-satellite weapons, ASATs, to physically damage a satellite. And basically what they do, it's very, you know, we all kind of laughed when Armageddon came out about sending people up there to drill holes and then drop bombs in it. But when you look at some of these things that we've thought to do, they're all kind of rudimentary like that. Like let's just send something in there and ram it into a satellite.
Starting point is 00:20:21 Yeah. Shoot a missile at that thing. The old fashioned way. Yeah. That's called the kinetic kill model, which is, it's exactly that. You shoot a missile at a satellite or something up in space and you blow it into smithereens, as Yosemite Sam would say, right? So you don't want to do this, but a lot of countries do, like you listed. They have not only just the technology, but I've actually done this, have run these tests. And I think it's kind of a two-fold show of force where you're showing that like, I can launch really technically sophisticated stuff up there that I don't want anyone else to know about.
Starting point is 00:20:59 And then I can destroy it before you could ever possibly find out about it. Yeah. Or I don't like your satellite and what it's doing. I'm going to shoot that thing out of the sky. I just showed all of you that I'm capable of doing it. So it makes sense, I guess, in a geopolitical way, but up in space it makes zero sense. Because when you blow up a satellite or something, you blow it up into thousands of pieces of that grapefruit softball, snowball size, debris, and then millions of smaller pieces. And now, all of a sudden, the population, that catalog of space junk, just increased by 10 or 15 or 20%,
Starting point is 00:21:40 depending on how big the explosion was and how much debris it created. Yeah. And you might think because there have been satellites launched basically continuously for, you know, many, many decades now, that they're banging into each other at a decent rate. But that's actually not the case yet, as far as actual satellite collisions. In February 2009, the very first one happened, the Cosmos with a K. So, you know where that one's from, the Cosmos 2251 out of Russia collided, and it was defunct, collided with, I think, a private one from a U.S. company called Iridium, which sounds like a total sci-fi movie bad guy company. I know, I don't actually know, it doesn't strike me like that. I get what you're saying,
Starting point is 00:22:25 but I think it's a very pleasant word. Oh, okay. It makes me think of the Rainbow Centrum Vitamin logo kind of. Oh, Iridium? Yeah, I find it very pleasant. Yeah. Well, one guy's Evil Corporation is another guy's Rainbow Fighter. That's right. They were traveling at a speed relative to each other of about 22,000 miles an hour and blew them up into, you know, 2000 pieces at least four inches in diameter. And then, like you said, thousands and thousands and millions of tinier and tinier pieces. Right. So, this is the first time that was 2009 where two satellites rammed into each other as far as we know. And I think it hasn't happened again yet, right? No, but the thing is, is because there's so many satellites up there and we're launching so many
Starting point is 00:23:15 more that it's going to happen again. It's just inevitable that it's going to happen again, because you'll notice, you know, while the Iridium satellite was operational, that Cosmos one was in operational, meaning there's no way to control it or move it. So, the only way to avoid this collision is for the Iridium controllers to move theirs. And I guess they didn't have the warning or why they didn't move it, because there's, as we'll see, there's a, there's collision maneuvers where you just basically move your satellite out of the way, if you think it's going to hit something. But that didn't happen with this one. And so, because there's so many satellites that are defunct out there that are traveling in opposite directions at really high speeds,
Starting point is 00:23:58 of course this is going to happen again. And the Union of Concerned Scientists says that there's something like 3,372 active satellites in orbit and at least 3,000 more inactive satellites in orbit right now. So, it's definitely going to happen again. Yeah, I think the Union of Concerned Scientists logo is, I looked it up, it's just a silhouette of two folded arms with lab coats leaves. Scowling. Scowling arms. So, yeah, it's going to happen again. I think there was one ESA official of the European Space Agency, and this is paraphrasing, but said it's basically what we're doing is like every time a ship goes out to sea, just leaving it out there. Like, eventually this is going to be a real problem. And I know that it's hard to imagine
Starting point is 00:24:53 because it's in space, but let me liken it to the ocean and boats and it might get through your thick skulls. Right, yeah. So, yeah, it's basically a tragedy of the commons that we're seeing right now. But the commons are becoming more and more crowded as the days go by. That 3,372 active satellites in orbit, I think that was as of the beginning of 2021, the end of 2020. That was a thousand more active satellites than there were in 2019. Yeah, the rate is picking up for sure. Like exponentially. And one of the reasons why it's picking up exponentially is that a lot of companies, I think there's at least eight companies right now that have proposals to release what are called mega constellations
Starting point is 00:25:37 or swarms of satellites. And you would need a swarm of satellites because these things in lower Earth orbit travel so fast that if say like you're connected to one for your cell phone, it's suddenly gone. So they hand it off to the satellite behind them and behind them and behind them so that you can continue service. So the more swarm of satellites you have, the more connected you could be. And so some of these proposals like SpaceX's Starlink swarm, it aims to create like global coverage of satellite internet service. So everyone everywhere in the world will be able to connect to really high speed Wi-Fi because of this swarm. So there's a benefit to it. But at the same time, the SpaceX constellation requires 12,000 satellites. There's only, it's called a
Starting point is 00:26:25 swarm. There's only 3,300 up there right now. And Elon Musk is saying that he's going to add another 12,000 just with his swarm. So all of these satellites that are going up in the process of going up are about to make the whole thing a lot more crowded. So yes, the likelihood of a collision just is increasing by orders of magnitude every year from what I can tell. Yeah. And you know, obviously one of the big risks here, and we'll talk about all of them, something falling onto Earth and hurting people is one of the smaller risks, even though that has happened when Skylab very famously fell out in the western Australian outback. But we'll get to that. But that's not the biggest risk. The biggest risk is for damage and collisions up there. And
Starting point is 00:27:16 we've got a lot of astronauts up there. We have people living on space stations. We have people working on that Hubble telescope. And I mean, that was the movie Gravity, right? That was Space Junk that caused their whole thing, right? Yeah, they basically depicted a Kessler syndrome chain reaction. I guess the localized one in that movie from, I totally forgotten about it, but I kept seeing references to it. So yeah, I kind of remember it now. Like, isn't that why she had to take shelter somewhere with the ghost of George Clooney? Hey, who wouldn't though, you know? Did he even exist in that movie? I don't remember. Yeah. Is there a theory that he was not real? No, I just didn't remember if like he, if like at the end they were like, and he never really existed.
Starting point is 00:27:59 So he was there. She was just remembering him later or imagining him there later on, right? I think so. I mean, I only saw that once. Same here. Yeah. But even stuff like we said, as small as a paint fleck, if it's going 22,000 miles an hour, a one centimeter paint fleck can inflict enough damage as a, or the same amount as a 550 pound object going about 60 miles an hour here on earth. And if that goes up to 10 centimeters, it'd be comparable to a 7 kilogram TNT blast. Paint flecks. Paint fleck. Marbles. Yeah. Pretty amazing stuff, if you think about it. And actually, they've had to replace windows on the space shuttle back when the space shuttle was in operation in the U.S. And they, there'd just be like deep gouges and streaks taken out of the windows. And when
Starting point is 00:28:56 they would analyze and they'd be like, that's paint, paint fleck did that. Yeah. And you know, the ISS and a lot of our work happens below where most of this stuff is, but it's still a danger. It is a danger. So one of the reasons why it's a danger is because again, the, the ISS is, it's, it's 250 miles above earth, 403 kilometers above the surface. It's in lower earth orbit. But it is one of the most vital pieces of space technology that's up there right now. So we want to protect it. We want to keep the ISS safe. The problem is, is that there's a lot of stuff above it. And when that stuff eventually comes back down to earth, it might pass by the ISS coming down. And then the stuff that's also in lower earth orbit around the ISS could run into
Starting point is 00:29:47 it from the side or from the opposite direction or like at a 90 degree plane. So the ISS is constantly under threat. And NASA's, and I think the ESA, a bunch of different agencies that use the ISS have come up with procedures for basically moving it if, if there's a high enough chance that, that a collision will occur. And when we talk about high enough chance, we're saying like a one in a hundred thousand chance is enough reason to move the ISS out of the way. Yeah. And they came up with a pretty, I mean, it seems pretty obvious, but it's a pretty smart way to determine if it's dangerous or not. They said, we need to get an area around these things where we can determine if it's, you know, basically a close call or not. And we're going to call it
Starting point is 00:30:36 the pizza box because that's what it looks like. Sure. And everybody loves pizza. Everyone knows what pizza is. Do we have to describe that? Please. No. We have an episode on pizza. So go listen to that. There's some guy eating a grapefruit who's like, never heard of pizza. But it's shaped like a pizza box. It's flat and it's rectangular. It's about 30 miles across a mile deep, 30 miles long. And the idea is that, you know, imagine the ISS or whatever important satellite in the middle of this pizza box in space. And they say, if anything, if we predict anything will come within the bounds of that pizza box, then that means that we have to get together and decide what to do at least. Not necessarily take the action because then you
Starting point is 00:31:20 got to determine the probability of collision. But that's when it gets their attention, I think. Right. So if they figure out that there's a one in a hundred thousand chance of collision and moving the ISS isn't going to just be like, well, the mission's scrapped now because we needed the ISS three feet to the left. And now we can't do anything. So just forget it. Just forget the whole thing. They will move the ISS. If there's a one in 10,000 chance of collision and it won't jeopardize the lives of the crew, then they'll move the ISS, mission be damned. Right. They don't take that lightly. And then one other thing they might do, if they don't have time to move the ISS, they'll put the crew into whatever capsule brought them
Starting point is 00:32:10 there. If the Soyuz rocket that brought them there is docked or if one of SpaceX's Dragon capsules is docked, they'll say go in there and hang out until this predicted collision passes. But to hang out there, it's like a lifeboat, basically, for them. Yeah. That's the one, the only one that confused me a little bit. I mean, I get the idea that that's a good idea to be sort of in the escape pod, but that escape pod can also be crashed as well. Yes. Good thinking. You would make a very fine NASA flight engineer because I was reading an account of Scott Kelly, one of the Kelly twins, the astronauts who are just so great.
Starting point is 00:32:51 Scott Kelly was up on the ISS once as a commander. I think when he was spending that year in space, and there was a predicted collision that was enough to tell him to go sit in the Soyuz rocket, and they said, but don't close the hatch because it's possible that the capsule could get hit, and you might need to get out of the capsule really quick too. But then, if the ISS is hit, you can close the hatch very quickly and disembark, I guess. I wonder if they did that for the very first time. They said, just go get in the escape pod. I'm simplifying things, of course, for Star Wars fans, and they go get in the space pod and close the door, and they go, all right, we're all good now, right? And then they look at each other and they're like, not really.
Starting point is 00:33:38 Yeah. We're just in another thing. It was an interesting account. They were just kind of, he said it was a little tense, but then the time, the predicted time of collision came and went, and they were finally like, okay, can we get out now? But he said it was a little, like it was very quiet, and they could just hear themselves in one another breathing, and that was about it. I mean, it's dangerous work, and they understand this, but the goal is to bring them all back always. But it's like being a firefighter or something. You know that there's a risk that you might not come back. There's got to be. Oh, yeah, for sure. I mean, you just want that to be as minimal as possible. Yes. And they take extraordinary
Starting point is 00:34:19 measures to make sure that it's as minimized as possible, for sure. Should we take another break? I think so, man. And we're going to come back and talk about what to do about this space junk problem. Hey, I'm Lance Bass, host of the new iHeart podcast, Frosted Tips with Lance Bass. The hardest thing can be knowing who to turn to when questions arise or times get tough, or you're at the end of the road. Okay, I see what you're doing. Do you ever think to yourself, what advice would Lance Bass and my favorite boy bands give me in this situation? If you do, you've come to the right place because I'm here to help. This, I promise you. Oh, God. Seriously, I swear. And you won't have to send an SOS because I'll
Starting point is 00:35:13 be there for you. Oh, man. And so my husband, Michael. Um, hey, that's me. Yep, we know that, Michael, and a different hot, sexy teen crush boy band are each week to guide you through life step by step. Oh, not another one. Kids, relationships, life in general can get messy. You may be thinking, this is the story of my life. Just stop now. If so, tell everybody, yeah, everybody about my new podcast and make sure to listen so we'll never ever have to say bye, bye, bye. Listen to Frosted Tips with Lance Bass on the iHeart radio app, Apple podcast, or wherever you listen to podcasts. I'm Mangesh Atikular. And to be honest, I don't believe in astrology. But from the moment I was born, it's been a part of my life. In India, it's like smoking. You might
Starting point is 00:35:58 not smoke, but you're going to get secondhand astrology. And lately, I've been wondering if the universe has been trying to tell me to stop running and pay attention. Because maybe there is magic in the stars, if you're willing to look for it. So I rounded up some friends and we dove in and let me tell you, it got weird fast. Tantric curses, major league baseball teams, canceled marriages, K-pop. But just when I thought I had a handle on this sweet and curious show about astrology, my whole world came crashing down. Situation doesn't look good. There is risk to father. And my whole view on astrology, it changed. Whether you're a skeptic or a believer, I think your ideas are going to change too. Listen to Skyline Drive and the iHeart Radio app,
Starting point is 00:36:48 Apple Podcast, or wherever you get your podcasts. Okay, so we, I think, have established that space junk is kind of a problem. And not just for the ISS, not just for satellites. I think one thing we kind of left out is if these satellites crash into each other, there's somebody's dish TV gone. How are you going to watch the big game then? You're not. So space junk affects us one and all. And there's all sorts of other things that could happen if our satellites start going out. It's not something we want. We also don't want the crew of the ISS to get hurt. But also eventually in the future, when we go back to the moon and then when we travel beyond the moon, we're going to be needing to go in and out of Earth's orbit. And
Starting point is 00:37:47 we don't want there to be some crazy debris field that we have to navigate around or wait to pass or whatever. So this is something we need to mitigate right now. And it is just beginning to be something that some of the space agencies, not all, unfortunately, in some countries and some companies are starting to take seriously and figure out how to mitigate. Yeah. I mean, think about space tourism and all these companies. They're like, hey, how'd you like to fly up there for $100,000? Exactly. And risk being plowed into by paint flecks. Right. A paint fleck, being taken out by a paint fleck is just undignified. So the UN gets involved a little bit and they say, hey, how about everyone, all you companies sending satellites up there? Why don't you promise
Starting point is 00:38:35 to remove these things 25, at least 25 years after the end of their mission? And everyone said, sure, we'll do that UN. How are you going to enforce that? And the UN says, I don't know. Yeah. We're asking nicely though. Right. All the space agencies kind of slowly encircled the UN and then grabbed it and gave it a wedgie. But people, I'm kind of joking, but people in these agencies, they do know it's a problem and they are coming up with things kind of Armageddon style. I mean, literally space net. What is it with you and that movie? I just always thought it was the dumbest thing. Like, how am I supposed to believe this? That this is how they're going to solve this problem by just blowing this thing up by drilling
Starting point is 00:39:20 holes in it and putting bombs in it. And then the more I read about stuff like this, the more I think that's an actual idea that they could do. Yeah. Yeah. I mean, we're like maybe a decade off from space mining, I would guess, like mining asteroids. I just, I feel like I don't want to give Michael Bay credit for coming up with a plausible thing because I just still want to say he's ridiculous. Okay. But it's not because they have space nets and they have space harpoons and space magnets. And these are some of the things that they actually use to drag these things close enough to where it falls out of orbit and then ideally burns up. Yeah. Like remove debris, right? Yeah. Remove debris was, it was kind of cool. The European Space Agency said,
Starting point is 00:40:09 you know what? We have this defunct satellite up there called the invasat. And why don't we just put a bounty on this thing to see what people can come up with and just say, you know, go hog wild and see what you can, see what you can do, Bruce Willis. Yeah. You got to tell them about invasat and what it is and what it's doing right now through space. Well, I mean, it's, it's like a, it's about the size of a school bus. And it's like it's being driven around by a drunk. Yeah. Like auto after he took some shrooms or something. Totally. It's spinning uncontrollably through space. It's like actually one of the more dangerous things up there in the space debris fields right now. Yeah. So they put out this call, said, who's got a good idea? Feel free to try it
Starting point is 00:40:51 on the invasat if, if you want to get close to it. And in 2018, a group from Surrey University came up with that remove debris system where it was basically a ballistic module that attacked this stuff with a harpoon and a net and pushes or pulls it out of orbit and basically just kind of speeds up the process. It's not like they literally drag it back down to earth and, you know, stand on it and get their picture taken. But they disrupted enough to speed up the process that would inevitably happen anyway. Yeah. It's kind of close to that though. Like there's the, the test that they ran in 2018, like the net was successful, the harpoon was successful, but then it's supposed to also deploy a drag net to like slow the thing down and then make it,
Starting point is 00:41:38 you know, fall toward earth. But the drag net didn't, didn't go. But everything else did. And then there was another company, a Swiss company called Clear Space that was working directly with the ESA to launch claws, little claws that go seek and find space junk, clomp onto it and then just basically drag it down and to its own death kind of like, you know, the, the guy that you just were, you pushed off the cliff and he grabbed onto your ankle and then at the last second he took you down with them and you both go, that's what this claw basically does to this poor space chunk. Yeah. The magnet thing kind of, and we did a show on magnets and I remember it kind of broke my brain, but is there such a thing as a magnet that when it attracts
Starting point is 00:42:28 things, I'm glad there was more to that question. When it attracts things that stick to the magnet, those things also become magnetized. Oh, that's a great question. It's gotta, because you know, what I'm getting at here is basically a magnet that just keeps growing and growing and growing and just spinning through the universe, collecting everything in its bath until it's this giant thing. Chuck, that is the very title of the third album by Buffalo Space Junk. It was a long one, not as long as Fiona Apples, but I think it's second place. Her new album's great, by the way. I haven't heard it, but I imagine she's a genius. But I don't know, it's probably a silly idea, or maybe just a magnet big enough to collect enough stuff and then blow that thing up.
Starting point is 00:43:13 I would guess, I mean, I don't think it's a silly idea. I think magnets probably are the wave of the future for this stuff because harpoons, nets, claws, all of these things work for, say, intact satellites, large ones. And by the way, the ESA backed off of its invasat bounty because it realized very quickly we're many years off from being able to take something that large out of orbit. Yeah. So it's still going strong. It is. It's still hurling uncontrollably through space the size of a school bus. But the still, like, large pieces that these things take. And as we've said, smaller debris is a real, real problem up in space. So I could see it being something like magnets or a whale shark's filter teeth kind of thing, but up in space that somehow collects
Starting point is 00:44:04 debris in a bag. I don't know exactly. Like krill. Yeah, basically, like treating it like krill. We need a robot space shark. Space whale shark. Swam with whale sharks 100 years ago? Of course. Can you imagine ever forgetting that? That was so long ago. Isn't that crazy? It really was. It was a good decade, right? No, it had to be. I'm just sort of marveling that we're still doing this job. I know. Got a long time left too. So wake up. I hope so. Are you telling me to wake up or everyone else? Everybody else. Okay. There are also deorbiting. I mean, we have successfully, and other companies have successfully deorbited satellites. It is a thing. We don't leave everything up there. SpaceX, I remember very
Starting point is 00:44:51 famously they have the Falcon rocket that was able to come back down to Earth and docking again. It was super cool. Yeah, you know who thought that was excellent? Don Docking. Everybody was talking about him that day too, and he loved it. Yeah, he made the news. Yeah, so that's actually a new best practice is basically reuse stuff. Just get it back out. And even if you can't reuse it again, like SpaceX does with their boosters, at the very least make part of launching a satellite, deorbiting the upper stage of the rocket immediately. There's no reason to just leave your rocket parts up there anymore. You can attach stuff to it, propulsion systems, to get it back down into Earth's atmosphere to burn up if you're not going to reuse it.
Starting point is 00:45:38 So that's a definite best practice that's emerging for sure. The Falcon worked though, right? Didn't that thing land safely? Dude, I saw it with my own eyes. I saw the heavy boosters land with my own eyes, and he synchronized them. They came down at the same time, landed at the same time after launching a rocket in the space. Yeah, for sure. I mean, that's really cool though. And I gotta hand it to that guy. He definitely thinks of things that don't seem possible, and somehow is able to make them possible. I know. I mean, that's another thing too. There's a lot, a lot you can say about his personality, but some of his problem-solving skills make things seem like so... It makes it look like you turn to everybody else and be like,
Starting point is 00:46:27 why haven't you been doing this this whole time too? Like for example, the starship, the thing that's going to start ferrying people to the moon and beyond eventually, one of its things is going to be when it comes back down to Earth is to collect space junk on the way. Or the Starlink satellites, SpaceX's Starlink satellites, they're all going to be able to autonomously move based on debris tracking data here on Earth. So they'll just be able to move themselves. There's just like, just basic stuff that seems like, why haven't we been doing this all along? I mean, it's a good question. It's been a while since you've fanboyed on Elon Musk. I know. I've had some ups and downs since then too. I mentioned earlier that in 78,
Starting point is 00:47:13 Skylab fell in Western Australia. What we can't do as human to say, well, it fell in the Australian Outback. It's very sparsely populated, so it's all good. There are people there, and there are ecosystems there, and it is nature and the planet. It is a big deal, just because it didn't fall on New York City or downtown LA or something doesn't mean it wasn't a problem. It was a problem. I think in 2019, NASA said that as much as 16% of that ISS is going to survive reentry when it eventually comes back down to Earth, 16%. Yeah. So when you have something like the ISS whose ultimate fate is up in the air still, literally, you have to plan to de-orbit it. Like, you can't just leave something that big up there. It would just create too much space debris.
Starting point is 00:48:07 And other space stations like the Mir and China's Tiangong two, I think one and two space labs, both were brought down, and some of this stuff is going to survive. Like you said, the space stations, part of that is going to survive. Some of the Mir survived. Some of the Tiangong survived. And you don't want that re-enactment of Skylab. So they've figured out that if they crash land these things into like a really remote part of the ocean, probably it will be fine. And there's a point in the ocean, in the South Pacific Ocean, called Point Nemo. And NASA and the other space agencies have been landing, crash landing, de-orbited enormous stuff there for decades. But it wasn't until 1992 that a survey engineer named Vorje Lukatala. Nice. Thank you. His Croatian,
Starting point is 00:49:06 I believe, used this brand new software, this is 1992, and triangulated the furthest spot from land in the world. And he said, it's basically Point Nemo, this area that the space agencies have been using already for decades. They had it basically right on the money. Yeah. So I mean, it's 1400 miles away from the nearest land mass. It's supposedly the one point on earth, further away from any other piece of land. And a little fun tidbit about those, that exact degree of longitude and latitude is that HP Lovecraft wrote about the old ones where the old ones lived and actually gave coordinates that were really, really close to these actual calculated coordinates. It's kind of great to think about that. But I also think if you had a good enough flat map of
Starting point is 00:50:03 the earth, you could probably stand back and eyeball what looks like it's furthest away from anything and you're probably close to Point Nemo. Yeah. Because that's what NASA did. Yeah, that's basically what they did. And so this area, Point Nemo, I mean, the fact that it's called Point Nemo makes you think like, man, they've been crash landing spacecraft and space stations there for decades. This must just be like the most amazing place to go tour in like a sub. But the thing is, is when you crash land something like a space station, the debris field that creates as it's coming into the ocean could be almost a thousand miles long. And it's not like they hit the target every single time. So it's actually like a really huge, enormous tens of thousands,
Starting point is 00:50:48 if not millions of square miles wide area. That's what Point Nemo is. It's kind of a misnomer, actually. Yeah, because I think people like, when is it going to start poking its little head above the ocean surface like a big stack of junk under there? Exactly. Pretty cool though. It is very cool. And also if you're like, well, what about the fish? Do not worry. It turns out that Point Nemo is one of the least biodiverse parts of the ocean around. So they say. And get this Chuck, you want a little cherry on top of our Sunday here? I would love that. I always love the cherry on top. 99% invisible has not done an episode on Point Nemo. In your face, Mr. Mars. Feed him to it. That's awesome. There's a recent episode that they did on the movie theater mega
Starting point is 00:51:40 plex history that's really great. Oh, yeah, of course. I mean, it's 99% invisible. Yeah. You got anything else? I got nothing else. All right. Well, if you want to know more about space junk to start reading about it, there's a lot of really great articles out there. And since I said that, it's time for listener mail. I'm going to call this what the writer called it. My husband is jealous of Josh and Chuck. Oh, okay. I hope you guys are both well. I wanted to share with you the stuff you should know is having an unpleasant effect on my marriage. You see, my husband works nights and while I'm a strong independent person who could hold my own, I still like to have a little background noise to soothe me to sleep. Most nights that means falling asleep to the
Starting point is 00:52:21 dulcet tones of maybe how the black panther party worked or origami colon folding goodness. Every morning when my husband gets home, he begrudgingly acknowledges the other men in the room and pauses my app. However, we hit a breaking point recently when he returned to find the stuff you should know incomplete compendium of mostly interesting things book open on his pillow with me snuggled against it comfortably. Enraged, he tossed it on the floor and we exchanged words. Oh boy. So yeah, you could say my husband is super jelly of Josh and Chuck. All that to say, here's a big thank you for keeping me company and helping me helping this gal sleep tight every night. Lots of love to my main squeezes. Ray, she hers from Phoenix. All right, Ray. Hopefully that was mostly tongue
Starting point is 00:53:12 and cheek. I think so. I hope so. I don't want to be a problem in anybody's marriage, you know? No, just our own. Right. Well, thanks a lot, Ray, and sleep tight as always. Hopefully you guys can work it out. Maybe just get him to read the stuff you should know book and he'll be like, no, I want the book tonight and that's where your problems will be. Yeah, that's the easiest thing is to convert him. Exactly. And we have ways you can sign up for our brainwashing newsletter if you want some tips. That's right.
