Summary

This episode of We WOW on the Weekend features a fictional adventure where hosts Guy Raz and Mindy travel to the International Space Station to deliver a letter. The episode explores real space suit technology, including NASA's EMU suits, liquid armor innovations from the University of Delaware, and MIT's shrink-wrap space suit prototypes designed to protect astronauts from cosmic radiation, extreme temperatures, and micrometeorite impacts.

Insights
  • Modern space suits integrate multiple life-support systems including thermal regulation, oxygen provision, CO2 removal, and radiation protection to ensure astronaut safety in extreme environments
  • Emerging liquid armor technology using silica and polyethylene glycol compounds can harden on impact and return to liquid state, offering puncture-resistant protection for future space habitats
  • Space suit innovation involves collaboration between government agencies (NASA) and academic institutions (University of Delaware, MIT) to develop next-generation protective equipment
  • Space dust traveling at 10,000+ mph poses significant hazard to spacecraft and requires specialized material solutions, driving ongoing research into protective fabrics
  • Future space exploration infrastructure will require innovations in portable habitats and protective gear to support long-term human presence on Mars and other celestial bodies

"When these little pieces of space rock are traveling that fast, they can cause some serious damage."
Mindy
"The suit even has a special gold-lined visor that protects the wearer's eyes from bright sunlight. Like one massive pair of sunglasses."
Guy Raz
"When it's hit by something like space dust or a micro-meteorite, it immediately hardens. And then, once it's over, it turns back into a liquid so that the material can be flexible again."
Mindy
"If it ain't broke, don't fix it."

Talking, laughing, me and Reggie, singing, laughing, and then we, oh wait, no, I said laughing twice. Ah, whatever. We WOW on the weekend. We WOW on the weekend. We WOW on the weekend. Cause this is what we do on the weekend. Hello and welcome to We WOW on the weekend. I'm your host, Dennis. And that's Reggie. Oh, nothing, Reggie, I'm fine. Well, it's just I was gonna start the episode off with a snobescoop. But, but, but everyone's being really boring today. Hey! No! No cookies and anagons. No wacky hijinks. Everyone's just sitting around enjoying their day. It's horrible. How you're right. I can still do the snobescoop, I just have to jazz it up a little. Okay, let's get jazz-y! Uh, um, but it's a deep, da, da, da, snoop, scoop, but it's a deep, gas, snoop, scoop, but it's a deep, da, da, da, da, da, a sneaky, it's Snoopy News, yeah! OK, that felt good, um, welcome to The SnoopScope, The part of the show where I tell you everything I've seen going on around the neighborhood. All right, Reggie, get this, today, I saw Guy Roz Oh, boy, and groceries! Oh, right, I got to jazz it up. Can you play saxophone? Oh, yeah, yeah, yeah, yeah, yeah! Oh, this is gonna be so great! Jazzy Snubscope, here we go! Today was boring. Almost too boring. I thought, where is everyone? And then, there he was. Out of the nowhere! Guy rise with a bag of groceries! I wondered, what was in that bag of groceries? Cheese, bread, vegetables? And that's when I saw her. Mindy, off in the distance, reading a book! I know, just when I thought this day couldn't get any more boring. Oh, but what's this? Why, it's Reggie! That's right, Reggie! You! You were coming right for me! Walking with purpose. But what purpose could that be? What business could Reggie possibly have with me? Dennis! Oh, that's right, you were just coming over to record the podcast. Okay, well that's been today's Snubscope. Jaz edition! Alright, let's do a reading review-segment. Because, Reggie, I wanna hear from my adoring fans! I'm reading reviews for me and for you, Z's. So let's read reviews! Z's. This is the part where I print off a bunch of comments that people left us on Apple Music or Spotify or wherever, and I read them aloud. Alright, go off on a tangent and forget what the comment was. Well, I don't know, it's definitely one of the two. Okay, here we go. This first review-segment comes from username, Lion. And Lion asks, what is your favorite type of sneaker? Good question! Well, of course we snoops our excellent sneakers. We have to sneak around all sneaky when we listen to people's conversations. But there are other kinds of sneakers, right? Like, foxes are pretty sneaky. Uh oh, and spies are also very sneaky. Spies are kinda like snoops, but they have more gadgets, which is very cool. Also on the sneaker list is... Oh, Lion meant sneakers like the kind of show? Well, in that case, my answer is red ones. Next review-se. This next review-se is from username, cool. Now, ready, cool, not cool. Close enough. Cool asks, do you like cake? Oh yeah, I love cake. I love the different flavors, and I love the frosting, and I love the decorating cakes with sprinkles. Oh, great idea, Reggie. We should bake a cake on dishen it up with Dennis. Okay, listeners, let us know in the comments what kind of cake we should bake. Next, refusing. Okay, this one's from you on you, who asks, what is inside a bug's body? Huh, I believe the scientific term for what is inside a bug's body is icky squishy bug guts. Okay, fine, that's not the scientific term. Well, what would you call the inside of a bug? Delicious! Oh, I forget how many bugs you ate. Yeah, okay, this conversation is making me itchy. Thanks for all your refusing listeners. Hey, bum, come in. If you leave me a comment on Apple Podcasts or Spotify, I just might read it on WeWOW on the weekend. Five stars or more, please. Okey-doke. Up next is a little segment I'd like to call Inside Tinkercast Studios. Ahem, inside Tinkercast Studios. This is the part where we revisit an episode of one of my favorite Tinkercast shows.

There. All done. Come in! Good morning, Guy Ross. Where are you? I'm in the...wow, you're even cheerier and happier than normal. What's up? Well, for starters, this morning I found some shrimp in my pocket that I forgot I put there a couple of weeks ago. And it's still kind of fresh. Here, if you want some, eat it. Well, I was just about to deliver this letter to my penpal. Your penpal? What? You have other friends besides me and Reggie? Well, Mindy, I happen to be a very popular guy. Ross. What? You happen to be a very popular guy, Ross. Oh, yeah, right. So this penpal I was writing to, well, she happens to be on the International Space Station. The International Space Station? The ISS? Yup. In her last letter to me, she signed off and wrote, see you later. See you later? Yeah. Ross, you know what this means? She wants you to come visit. What? Oh, my one-eyed cat, Guy Ross, you're going to the International Space Station. I don't know, Mindy, I suppose it would be a nice gesture to deliver this letter in person. Well, if you're going to deliver your snail mail to the International Space Station, Guy Ross, then I'm going with you. Come on, crack yourself. Let's go. Mindy, I'm not sure. See you later. Literally means I'll see you later. I mean, I think she was just being polite. No, no, no, no, no, no, no. She said specifically, I'll see you later as him. I'll see you later on the International Space Station, PS, bring your best friend, especially for name rhymes with Mindy. Are you sure about this, Mindy? Of course I'm not sure about this, Guy Ross. Now, go suit up and get ready to go. But I'm already wearing a suit. Guy Ross, a space suit. Okay, well, let me just run upstairs and put on my space suit. Just give me two seconds. Okay, just wait right here. Just make it snap, okay? All right. Okay, Ross, what is taking you so long? We're going to hit traffic on the way up. All right, good to go. Guy Ross? Yeah. You're wearing the exact same thing as you were before. That's not true. I'm now wearing my fancy Saturn couplings and my paisley bowtie. You look at it, spins. It's my space suit. Okay, Guy Ross. So you and I both know that space can be a seriously dangerous place. I mean, with all of that space junk just flying around up there, I think you're going to need something a little more substantial to protect you from the elements. Substantial? Like what? Well, you know how you need a big fluffy jacket in the winter to protect you against snow or rain? Yeah. Well, in space you need a special kind of suit to protect you against the dangers of space. Ooh. One that doesn't involve cufflinks or a spinning bowtie. The dangers of space like what? Well, instead of snow and rain, in space you have to protect yourself against things like cosmic radiation and space dust. Space dust? Ah, maybe I hate dust. That's why I get sick every time I visit your house. Oh, you're just allergic to dusty. Dusty, my pet dust bunny. That's what that thing is. And if you think the dust in my house is bad, just wait until you get a load of some space dust because that stuff can be deadly. But dust particles are so small, Mindy. I mean, how can something so small be so deadly? Well, because some of these particles can orbit or float around the planet at up to 10,000 miles per hour. 10,000 miles per hour? That's like five times faster than a speeding bullet. I know, right? And when these little pieces of space rock are traveling that fast, they can cause some serious damage. Whoa. In fact, some scientists actually refer to these tiny bits of space dust as micro-media rights. Micro-meaning really, really, really small in meteorites, meaning bits of space rock. You know it. I never thought I'd say this Mindy, but I think I might need a new suit. Guy-Raz, let's go shopping. No, really. I've been meaning to get a new space suit anyway ever since I grew out of my old one. Wait, you already have a space suit? Well, yeah, you want to see it? Of course I want to see it. Okay, you wait right here. I'll be right back. What? Tadda! Tadda! What is that, Mindy? I like it. It's so bright. It's hurting my eyes. It's like a disco ball. I know. Pretty retro, huh? This is my old space suit. I'll say, why is it so shiny? Oh, well, the first ever American space suits were made out of a reflective material called Illuminized Nylon. It's meant to reflect thermal radiation. Thermal radiation? Oh, that's the type of energy the sun gives off that makes us hot. Exacteritos! So this shiny material is actually used to reflect that energy back into space so that the astronaut wearing it doesn't overheat. Ah, I get it. Kind of like how you put a reflective sun visor on your car's dashboard to keep it cool on hot summer days. You know it. In fact, this is actually the same suit that astronaut John Glenwar. The John Glen, the first American to orbit the Earth? Yep, that's the one. My Aunt Mojo gave it to me. She used to cat sit for him when he went off on his space missions and he gave it to her as a thank you present. Yeah, maybe you should get a new space suit, Mindy. I think that one kind of belongs in a museum or something. I think you belong in a museum, GuyRaz. What? So are we going to go to the mall or what? Yeah, I'm ready when you are. Okay, let me just lock up the house. Ah, fresh air. Another beautiful day. Mindy, did you really think they're going to have space suits at the mall? Oh, yeah. They just opened up this new store called the Black Hole. And I hear the fashion in there is out of this world. Well, I think I'll be the judge of that. Reggie! Oh, we can't ride Reggie to the mall, GuyRaz. Why not? His Taekwondo lessons aren't for another four hours. There is no pigeon parking at the mall. Oh, right. Sorry, Reg. Looks like you're going to have to hang back this time. Mindy and I are... Mindy? Mindy? What in the... Up on back, GuyRaz. But first, put this helmet on your head. Mindy, this is a coconut shell in there. What is this thing you're sitting on, uh... Is this a... It's a motor pickle, GuyRaz. A motor what? A motor pickle. So last summer, I grew this monster cucumber that I later pickled and then realized it was too big to eat. So I just added a motor, some handlebars, and the wheels from your car. And now it's a motor pickle. And I built it all by myself. First in, only one of its kinds. Do you think it's safe to ride? Of course I don't think it's safe to ride. What? But I bet it tastes great. And did she just eat her motor? Mm-hmm. Now, hop on back and hold on for your life, GuyRaz. Mindy. You two, Reg. It's a three-seater. Mindy, I'm here. We... Yay! Whoa! Look at all these people checking out my sweet ride. I thought it was a sour pickle. Yeah, I went with bread and butter. Wow, everyone here really is looking at us, Mindy. I know. Isn't it great? Excuse me, everybody. Excuse me, nothing to see here. Nothing to see here. Just me and Mindy and the carrier pigeon riding on a motor pickle. Take a picture, Bob. That's longer. Mindy, can we go anywhere without causing a scene? No. Let's just get inside the mall. Okay. Come on, Reggie. Ah, the mall. Ah, Christmas music already? No, we can just... Can't pass the mall. These teens... Excuse me. Sorry. Sorry, coming through, coming through. Wait, wait. Hey, Reggie, where are you going? Well, just meet us back here when you're done, alright? And don't take any wooden niggles. Where's he going, Mindy? He says he has a job interview at Footlocker. What does Reggie know about shoes? Ah, oh well. Well, where is this black hole shop you were telling me about, Mindy? Oh yeah, so apparently you know you're there when you see it. Or rather, don't see it. I don't know. It's the only store that light can't escape from. Wait. Is that it there? Where? That store is pitch black. This is it, come on. Let's go inside. Oh, check this place out, GuyRaz. Look at all these awesome spacesuits, Rocelle. Yeah. Which one do you think would make the best impression with your new penpal on the International Space Station? You know, I hear you can't really go wrong with the Emo. Emo, what, GuyRaz? We're shopping for spacesuits. Not flightless birds. I know, Mindy EMU. Emo, it stands for Extra Mobility Unit. And it's the name of the space suit that astronauts at NASA have been using since 1983. Oh, yeah, the classic space suit. Yeah. Well, I guess life-saving technology never really goes out of style. And unlike any of the suits in my closet, the Emo space suit has built in technology that keeps its astronauts from getting too hot. Because of the Sun's thermal radiation. And from getting too cold. Too cold. Let me check the weather forecast up there. Oh, yeah. It says here, the forecast for space for the next several billion years or so is minus 454.81 degrees Fahrenheit. So you can see why it's important for that suit to keep the astronauts nice and warm. Oh, check this out. Another cool feature on the tag here says that it will also provide the astronaut with oxygen to breathe while also removing the carbon dioxide that the astronaut breathes out. Which is important because as the astronaut breathes out, she fills up the suit with carbon dioxide. And if you don't get rid of it, the astronaut can breathe it in, which if she does it for too long can be deadly. Yikes. So air filtration or some kind of a feature that helps to remove the carbon dioxide from the suit is a must, right? Exactly. And check this out, Mindy. The suit even has a special gold-lined visor that protects the wearer's eyes from bright sunlight. Like one massive pair of sunglasses. Yeah, cool. Well, I have to say Mindy, I am S-O-L-D-Sold. Hey, you want to check and see if it's on sale? Mindy? Mindy? Oh, there is. I'm over here. Check out this rack of prototype suits. They're bonker balls. Mindy, I'm not looking for any bonker balls and whistles. I just want whatever suit is going to keep me the safest. Oh, well, there's a ton of research that goes into safety and look. These suits are new and improved. Yeah, I don't know. You know what I always say? If it ain't broke, don't fix it. No, you don't. You always say, if you can't find quinoa, cheesies are a good substitute. Well, it is true. Ooh, check this one out. The tag here says it uses liquid armor technology. Liquid armor? Yeah, I was just reading about this. So remember that space dust we were talking about earlier? Yeah, the micro-media rights. Right, so those micro-media rights can sometimes puncture, put holes in an astronaut suit. Kind of like when your bike tire goes flat. Yeah, but only like a thousand times worse, because the error that escapes the suit is the same error that the astronaut needs to brave. And so this liquid armor makes these suits unpuncturable? Yeah, looking at the tag here, it says this new suit is made with a new kind of liquid armor technology. It was invented by scientists over at the University of Delaware. So what do you know about this unpuncturable technology? Well, from what I understand, the scientists start with a special kind of gloop. Ugh, yeah. Which is made up of a mixture of a chemical compound called silica and another chemical called polyethylene glycol. Which would make a pretty rubbery type of liquid, right? You know it, but the researchers found out that this gloop had a very interesting power. Huh, what's that? Well, when they hit this gloop with a fast-moving object, it immediately hardened. Wow. Then, after it was all over, the gloop softened and went back to being a liquid. That's incredible, Mindy. But what does all this have to do with this swanky new space suit? Well, the space fabric that this suit is made of has been soaked in that gloop. Ugh. It's just gloop, Kyra's. The researchers soaked and smothered the fabric in this gloop and let it suck it all in. And then, they let it sit in. That's it. And then, the material suddenly becomes puncture-proof, like you couldn't even poke a pencil through it. Well, sort of. So when the suit gets hit by a fast-moving object, like that micro-meviorite space dust you were telling me about? Yeah, exactly. So when it's hit by something like space dust or a micro-meviorite, it immediately hardens. And then, once it's over, it turns back into a liquid so that the material can be flexible again. That's amazing. And I suppose this sort of poke-proof fabric could be used on all sorts of space-related gadgets, like future inflatable off-world habitats. Ugh, you mean space-tense, Kyra's? Exactly. The kind of tents that will make up the labs and the living quarters for the astronauts that may one day live on Mars. That is literally some out of this world camping. So how far off is this technology, Mindy? Well, it might be a little while before we see a poke-proof moon-balance, but the results should be in pretty soon. Ooh. In fact, last November, NASA sent a sample of this fabric and put it on the outside of the space station. And they're just gonna leave it there? Yeah, they're gonna go back in a year to see how it's been able to handle all of the space dust and the micro-meviorites coming at it. Tab is thorough. Okay, let's see what else we've got here. Looks like they've only got an extra large in this one. Um, purple, really? Dior? That's not it. I didn't even know they did spaces. Ooh, what about this one, Mindy? What? Let me see that tab. Shrink wrapping space suit. Huh? Oh, yeah. I've heard about this one. This is from the folks at MIT, right? Yeah, but what is it? Well, Mindy, it's essentially a space suit that shrinks to fit to your body. You simply put it on, press a button, and the suit literally shrinks wraps to your body. Whoa, it's like one of those vacuum sucking space bags only for your body and for actual space. Well, sort of, but not really. So how does it work? Well, the fabric that this suit is made out of is interwoven with metal coils like springs, and they get tighter when they heat up, and then they get looser when they cool down. Right, so once you suit up, you press a button, which heats up these metal coils, which makes the suit tighten to your body, and then when you want to take it off again. You just cool them off. The coils loosen, and you're able to take the suit off. Well, how do you cool them off? I mean, do you have to step into a giant refrigerator? Well, I'm guessing there's a reason this suit's still on the prototype section of the store. Yeah, I might need a little more time to work out the kinks. You know, guys, I think I'm going to just go with the extra vehicular mobility unit, just a standard oldie move. Yeah. It's a great space suit, and it gets the job done. Yeah, me too. You can't go wrong with a classic. I'm going to grab these suits for us, and I'll meet you at the register. Wait, what size do you wear? Let's see, you're up 48, but generally 36R and US sizes Canadian, not so sure. Got it! I'll just grab the smallest one ever. Oh, I got it! Oh, okay. Hi, hi, excuse me. Yes, I just the two extra vehicular mobility units. Okay, let's see here. That one. And that one. Oh, I got it. Oh, okay. Hi, hi, excuse me. Yes, I just the two extra vehicular mobility units. Okay, let's see here. That one. And that one. Now, did anyone help you out with your purchase today? Uh, no. Have you heard about our out of this world Christmas sale? Christmas, whatty, it's March. When you purchase two or more nestle certified spaces, you can purchase a lunar rover at 25% off. I think we're fine with just that. And did you care to donate $5 towards SETI? That's the search for extra terrestrial intelligence. Every dollar makes a difference. Sure. Thank you very much sir. Now, if I could just get your email address. What? What for? Okay, no email address. Your total comes to $24 million and 32 cents. $24 million? And 32 cents. And space travel is surprisingly expensive. I'll say. How will you be paying, sir? Cash, credit, or fact? Fact? Yes, fact. It's a promotion we're running this month. You can pay with fun out of this world facts. Uh-huh. Okay, well, I guess I'll take that. I got this one, Gairaz. What? It's my treat. Excuse me, sir. I'd like to pay with the fact. Okay. Did you know that there are more stars in the universe than grains of sand on all of the beaches on Earth? Whoa, whoa. Really? Huh. All I say, that is really fun. Do you want to receive? Oh, nothing. Save the paper. Gairaz, hold my bag while I suit up. What? What's going to squeeze in it? I don't. Excuse me, sir. Is it okay if we wear these out of the store or, yes? Yeah, of course. Come on, suit up, Gairaz. Next stop, space. Okay, let me just get this. Get me a please. I can't little buddy. I'll hold your breath. Oh, thanks. Okay. Are we good to go? Now let's go deliver that letter to your penpal on the International Space Station. Wow, that was so cool. Did you hear the motor pickle, Reggie? I know. I want a space suit. I mean, I want an extra vehicular mobility unit too. Let's go to the mall and get some. All right, we got to wrap up the show. Thanks to all you listeners out there for tuning into. We wow on the weekend. If you have a question for me, call and leave me a message at 1-888-7. Wow, wow. That's 1-888-7. Wow, wow. I just might answer your question on. We wow on the weekend. Okay, should we do the goodbye song? All right, let's do it. That's the end of the show. I need to go and buy a space suit and some jeans and a cinnamon pretzel. But I'll do another show tomorrow. But for now, it's the end of the show. Bye.
