One simple request: when you are talking about Fahrenheit, is it possible to show the Celcius equivalent? You also compare MPH to km/h, so that would absolutly be great.
This is a great idea.
for temps high and low enough, dividing by 2 is a decent approximation.
I agree, there are a lot of people outside of America watching this, including me.
Aside from that the video was great :P
I agree. Or at least throw some Kelvin in there or something.
Ya bunch of Commies wantin' us to learn your goddamn "celceous" why dontcha come up with your own videos den . . . . . (Massive amounts of sarcasm and JK was put into this) :D
No word on Russian space suits which were engineered around the same time behind the iron curtain.
I'm very disappointed that you guys didn't cover any of the Soviet union space suits. I love yuri's bright orange space suit and being that he was the first man in space its a shame his space wear wasn't mentioned.
Scishow is probably the channel that makes me happiest when I see an upload :D.
I wish you'd put celsius on the screen or something when you say things in fahrenheit. I always have to pause the video to google a conversion when you use imperial measurements, since I have no real sense for what they mean.
They shouldn't be using Imperial at all. They should *only* be using Si units.
I think its quite poor for a science show to use fahrenheit at all.
While I agree with you, it's actually not that hard to get a general feel for it once you start doing the conversion yourself.
IstasPumaNevada I have that feel. I still think its poor.
What is celsius , like how do you exactly measure temperature using that, im glad they used imperial units idk how celsius works lmfao
Hey, you didn't talk about the Vostok program spacesuits. Not saying to bring up all the soviet space program, but I felt you missed some interesting facts skipping that. For instance, Gagarin's spacesuit and Leonov's EVA suit.
Since those are the first manned spaceflights it would be interesting to find out what was espected or not to withstand a spacesuit.
Oh wow, you got the Penn Jilette Voice Double to do work for SciShow? Nice...
Seriously, close your eyes, imagine him talking about his partner Teller.
Oh wow I never noticed that.. I knew his voice sounded familiar but you've got it.. He sounds like Penn!
LOL! You nailed it on the head! He sounds just like him!
Ha! Yep. I kept wondering who he sounded like... that's it.
Oh wow my boyfriend just said the exact same thing!
I knew there was a reason I liked his voice so much but I couldn't put my finger on it until I read this.
Why do you always skip past the Russian side of the space race? is it that a lot of that knowledge was classified and now lost or is there a case of history being written by the victors.Since this is a history about the Space suit, what did Yuri Gagarin wear during is space walk? and how did it compare to what the Americans were using at the time?
+Aaron Dunn Yuri Gagarin never went on a spacewalk, you might be thinking of alexei leonov, the first person to go on a spacewalk in space.
Aaron Dunn they were COMIS.COMIS!SUCK!
-290 to 310 Fahrenheit???? Please give us some Celsius or even Kelvin! You can give us km/s then you can give that too =D (Watching from Finland)
Btw for those who want to know it's -180 to 150 Celsius
LanttuLoL Easy thing to google. Now when i think of it it's weird that science show doesn't give temperature in degrees used in most of the world. Not gunning for international audience i guess. Hi! A fellow Finn! How Rare! (not very rare because there are 5 million of us but all nerds).
I too would prefer this, and I live in the U.S. At the very least, please give us metric units in text.
IstasPumaNevada i would guess the U.S. is easing into the metric system, because U.S. people got the feel of the imperial system(don't know if you get what i mean by the feel, its like this, when i use the imperial measurements the sense of size becomes meaningless, the numbers mean nothing until i convert back to metric. so i guess its going to be hard for americans to accept the metric system)
What's a FAHRENHEIT?
It's the customary system's(the measurement system that America uses) temperature measurement(32 degrees is the freezing point and 212 degrees is its boiling point, i know it's weird but that's what we use)
A single Fahrenheit is an individual integral degree on a temperature scale of the same name.
Stupid question gets a stupid answer.
Michael Hill I hit my head so hard thats its bleeding, thanks.
Michael Hill funny how you refer to the scaling points of Celsius. They are far more intuitive, although also pretty arbitrary. Kelvin is better, as it's only half as arbitrary as Celsius.
Yeah, As an American, I can say that the customary system is strange, that the metric system ,Celsius, and Kelvin are better but I've been using customary my whole life and haven't bothered to learn the conversions.
sry, but the space suit prototype shown doesnt look boss, it looks like a suit from a cheesy scy-fi movie from the 70´s xD
Maybe because thats where the shows got the image from?
well, the movies from the 70s didnt have any pictures of spacesuits from after 2010
I think we should be headed more in the direction of the Activity suit and not just because it's sexy! ...but partly because it's sexy.
I find it rather annoying that he doesn't speak about Soviet/Russian space suit technology. Even though they were the first in like... Everyting exept the moon.
But dude .. the MOON...
yea i dont like it either
when us media talk about the biggest achievement of man they allways ignore the first man in space and all the other achievements by their old cold war foes UDSSR
Actually, they were the first to land on the moon, just not land people.
Totally agree!
As a Russian I can say that I am very blessed for knowing the English language (thank you Internet!), because the Russian media, sadly, also ignores great discoveries and achievements by the USA. Sure, there might be some political disagreements, but it would be cool to at least see the scientific community/Intelligentsia get along. Just imagine what we could achieve as humanity if we chose knowledge over nationalism.
Artjom Yurkov as an american i fully agree and honestly, conversations like this and other forms of cultural mingling, though the great connector of the internet are making that goal more and more realistic.
i think i speak for most netizens when i say im wholeheartedly glad to be part of that process.
Artjom Yurkov
Indeed товарищ,
Let us abandon the silly ways of chauvinism and nationalism in favor of internationalism and the progress of knowledge.
I paused the video right near the beginning of 0:01, and Reid was totally the "Aliens" guy
i.imgur.com/wovL7X8.png
You're right. :P
Brilliant :P
Haha, it's brilliant indeed.
I really like this guy for Sci-Show, something about his voice helps me retain the information
I swear the video Icon looked like Buzz Lightyear
SciShow Space for the win :)
I love every SciShow episode
This guy is awesome, can listen to him talk about space all day! gg fellas
This is a science show, let's not be using none of that Fahrenheit bullshit now mmmmkay. The rest of the science world works in Kelvin or degrees celsius.
Other than that, love the show.
Fahrenheit is bad, m'kay.
Robasiewicz Damn right!
american here - even we think its ridiculous and barbaric
*****
it always bugged me. you guys can post an idea to the government online. some of you asked for a Death Star, why not ask for metric system?
Robasiewicz Let me just post that to the government.
you should tell us what the next video will be on because i would have been anticipate this!! Although i anticipate all scishow vids anyway!!
The Z-2 looks SO FREAKIN' COOL!!
I really like the channel and its content but I have to dislike this video because, once again, Imperial units are not the way to go with a science show.
referring to using Fahrenheit without even a Celsius conversion at 2:46
I'd rather a coherent, knowledgeable, well-produced, entertaining science show that fails to use SI than the majority of the crap videos and shows out there, so I have to like this video.
Hi, my name is Jesse. I just wanted to thank you so much for creating this channel and the videos on it! This channel are inspired me and the videos have taught me so much! Now all i want to do is look at the moon and the stars at night and i can't stop thinking about what out there beyond our understanding. Anyway thank you so much and i beg you, Never stop making these videos!
Reid, thank you for your contagious excitement with the topic, it's lovely ♥
Reid is so energetic and passionate about everything he talks about, it's awesome. Keep up the good work. :)
Fahrenheit, Fahrenheit ... that rings a bell somehow. Oh yeah, wasn't that this peculiar temperature scale that uses "pretty cold" and "kinda warm" as its 0 and 100 points? Funny you should bring that up. But wouldn't it make sense to also use an actual temperature scale like Kelvin or Celsius so that people know what you're talking about?
I've been watching since the first episode, you's (lexical gap fixed?) are doing a good job.
I appreciate each and every episode, Thank you.
The first thought that came to mind when I saw these suits was: "To infinity... and beyond!"
i don't like how the z2 looks.
Can you say Buzz Lightyear?"
URKillingme100 * . That would be better.
+Rinoa Super-Genius same
it looks so classic and ugly
Science channels working in Fahrenheit aren't science channels.
Pedantic, extremist positions contribute even less.
IstasPumaNevada Sure.
IstasPumaNevada It's a matter of conveying information in a proper manner.
This channel seems to focus on an American-generalized audience, which are used to F and not C. I hope this is why they do it, though Dragon has a valid point!
He does i personally think that the world should decide om what system to use if they really want to work together, im happy the scientist at least picked a side
Reid, you are so awesome. Many thanks.
I'm waiting for suit from Dead Space 3 :D
Don't forget that the first EVA ***in space*** was done by a USSR Cosmonaut Alexey Leonov. It wasn't pretty, but it happened.
You know.. the soviets and russians later also did their suit developments. They also have active research going in this area on like NASA.
+Richard Lushai
I couldn't agree more. Americans aren't the only one to develop space technology.
These videos always seem a bit USA-centric to me.
+Richard Lushai hahaha what? Later? Have you heard of Space Race? Google it.
*****
Because its a matter of principle to mention the developments that happened in the other major space agencies. And dont give me that "US website" or "US audience" bulshit or even the complete garbage of "US domination". Many develpoments in the space suit technology are still being advanced by the russians sometiems with US cooperation. Creaming jingoist.
***** Then you should get over yourself and stop the american humbum without knowing anything about the subject matter.
+JamecBond OK kiddo, (1) American is not a race (2) If you did know more you would know russian Sokol suits are the most commonly used suit the world now. Its used by NASA missions too.
Best vid so far. Make more like this and longer with more in depth history. It's so interesting and we know very little about it all...
How about one about the history or the space station or the status of the moon base?
The Space Activity Suit is a really neat concept. It's based off the fact that most of your body, like your arms and legs and torso, don't actually need the "air bag" that most suits use to contain an entire person. All you need is pressure on the skin to prevent swelling.
So the SAS uses a tight, form-fitting suit that keeps pressure over most of the body, which prevents body parts from swelling as they would in a vacuum, and uses a regular helmet for the head so that the eyes and respiratory system can function as normal while giving good range of motion to the head. Gloves too would need to be more flexible than the rest of the suit, but not needing to have the whole body in a bag of air drastically reduces the overall bulk.
Since you mentioned the Jet Stream what is sci-shows opinion on Contrails and Chem-trails?
Likely the same as most rational, scientific, and educated people: they are false.
Then an episode would be easy for them to do
Well, contrails are a real thing. Moisture in the air being tipped over the condensing point by the disruption of the surrounding air.
"Chemtrails" are myth, myth, myth. Bunk plus hokum with a side order of horse apples. Some very specialized planes do spray chemicals into the air. But nothing like the urban legends of "chemtrails".
***** No, conspiracy theorists this stupid don't deserve respect. Anyone who cares anything about the nature of truth and evidence would know what contrails are and that they aren't chemtrails. Reading the freaking Wikipedia page would explain what a contrail is.
Chem-trails, contrails. Short story: They happen way too high above the ground to create any lasting effects there, on top of being ridiculously expensive because of this. To spray a field of plants, the plane has to be at most 30 meters above the surface of the ground to get the job done.
Great channel guys, keep up the good work!
I would love to see a show about "oddball" space objects...pulsars, quasars, neutron stars, etc. I've always been fascinated by these things. A show explaining star classification might be cool too!
I like this guy, I also like watching his eyebrows as he talks. They're so expressive!
Okay, the last two shown space suits look so retro!
Cant wait to wear it!
Why didn't this include anything on the Soviet Union? I thought their suits would be more interesting, given how they had the first man, woman in space, and the first spacewalk, so I imagined their suits would evolve quickly
I don't know how Hank found this guy? I think he is excellent, loving the new channel.
thank you sir!
dear scishow, please use celcius for the rest of the world
it isn't that hard to go to google
As an American wtf is a Celsius
I hope I live to see stuff like that
Video idea: the problems with space travel. Affects of lack of gravity, dangers in types of radiation, that kind of stuff
episode idea: can you make a episode about the oldest things in the known universe!
awesome!
This is fascinating! I would love to help design a new space suit!
I didn't realize that this channel existed until I was filling out the Nerdfighter survey! :O
If you take inspiration into account the journey begins quite a few hundred years earlier. NASA got a lot of cues from medieval&renaissance plate armour, in particular the insanely jointed Greenwich Armour made for Henry VIII and the Knights at Elizabeth I.'s court and learned some valuable lessons there how to keep humans mobile while using rigid materials for what is essentially very overbuilt clothing.
Oh and how about some metric measurements? Turning miles into kilometres (within a rather large margin of error, but enough to get an idea of the scales involved) is easy enough on the fly, but I really dislike Fahrenheit.
I love this guy. Great content as always. The MIT model should be what we're aiming for.
I love this guy.
How the Z2 is less bulky is perplexing. It makes the pictured astronaut look "obese." Hopefully as the project goes on further some real-life pictures will do it some justice.
Man, that hoster is great!
I love this guy
Sorry man, the Z-2 does NOT look boss.
... he just need three guys standing to his left with M, C and A on their suits xD
I like this episode
Only downer: you used Fahrenheit >.< PLEASE USE SI UNITS =/
Besides that... another interesting and entertaining video as always :)
Keep up the great work!!
Better than the original!
You should send this link to Adam Savage from the Mythbusters. He LOVES spacesuits.
Great video!
Guys, good episode, but I miss more detail about the MIT approach to the space suit: pressure points over the body instead of an inflated "bubble" as the current space suits are designed (which makes the astronauts "fight" the suite instead of wearing it comfortably).
Guys, if you are going to talk in km/h, please talk in Celsius too, it's confusing for the rest of us that don't use the imperial system.
OK Serious question now.
Is it possible to make a space suit that doesn't use air pressure and inflate like a balloon to provide the pressure required to keep astronaut's bodies intact?
For instance, a tight fitting 3D scanned "second skin" that fits like a wetsuit in so far as it compresses the astronaut's whole body (up to the neck where it can meet an oxygen delivering helmet) to the required 1atm pressure?
That would give unlimited movement and presumably be more convenient and light.
The paraphernalia that astronauts then need (tools, etc) could be carried in a bag.
well that could work in theory, but I dont know any material light enough or strong enough that could do that. Also, they could compress multiple layers into one but thats way down the future line. Also, the protection wouldn't be there since thats what the bulkiness is for and also temperature control is a biggie. A thin suit wouldn't keep out the UV rays that could easily pass through the body. A thicker medium to translate, dilute, and absorb those rays is necessary
The problem isn't so much that the pressure is required to keep astronauts bodies intact, as long as the suit is airtight and not extremely stretchy, it will maintain whatever pressure you put it on in, so the vacuum shouldn't be much of a problem.
The major problem is radiation. Because there is no air in space to conduct heat away from your body, or to absorb radiation from the sun, you would actually burn before you froze, unless you were shaded from the sun, so space suits need to be able to reflect a large amount of radiated heat.
The other reason current suits are so thick and bulky is that they need to provide some sort of protection from ionizing radiation (the cancer causing type). Unfortunately it's not so easy to reflect, and the most effective substances at blocking radiation are lead, steel and concrete (extremely dense substances), not exactly optimal for building a thin, lightweight suit.
Don't think of them so much as space suits, so much as personal spaceships.
Xavier Toussaint woven carbon nanotubes
There is a TED talk on exactly this topic. The paper is web.mit.edu/aeroastro/www/people/dnewman/pdf2/WaldieNewman_AA_GLCS_2011.pdf
Pm Durand in some of my college classes Ive heard of that, but thats extremely on the theoretical side
great vid :D :D :D
but, it sounds somewhat like an Advertisement for spacesuits
I love how this guy presents, he's hilarious ;D
Does anyone know if he has another channel?
Nice, moderately paced delivery....
dude ! what an awsome voice !
My next generation space suit would be Denim cut out shorts with a pink tank top.
Loved this episode! Though I wish they had taken a moment to mention the fact that early modern suits were designed and built by the same people who made your Nana's bra, and that they won the contract for that honor over other military-backed designers. It's one of the more awesome bits of history that's almost completely ignored.
How do you know who made my Nana's bra? That's a bit creepy, especially as she's been dead for over 30 years ;)
Why the winkie face did you kill your nana?
Cameron Marcum Wow, that's even more creepy! What's with all the mind readers?
Not much on explanation-1. Why joints are difficult...because they must maintain exact volume bending and turning (cf elliptic weave innersuit); 2. Safety modes (cf hex weave outersuit, pulse breathing under loss of pressure); 3. Vaporlock lotion for low pressure... (points I discuss in my 2001 StarTrails Game screenplay)...
I’ve just started watching astronaut Chris Hadfield’s MasterClass on Space Exploration. That and SciShow Space complement each other well. (Along with, of course, Star Trek!)
I've read somewhere that, since the space suits used for the moon landings were white to reflect heat, the ones used for future Mars landings will be black to absorb heat.

"To infinity, AND BEYOND!" -Buzz Lightyear
I wonder if we could ever make space suit like suits that protect people from all sorts of things that everyone can wear. Like for example, something that could protect you from normal fire, and let you stay underwater for a while like a scuba suit. Probably would also feature an add on helmet for low air pressure like for fighter pilots- oh. Like those space activity suits.
So Wiley Post is basically Tony Stark of the 30's?
I would like to see some Russian contributions to this after all they were first in space.. first in space walk... First space station as well so its not just NASA but bring in contributions from around the world its for humanity... I support all sides and the Z2 looks AMAZING :) hope they use it one day
Yeah. The USSR had nearly three times more 'firsts' in space than the USA did.
I really like his voice.
2:47 ... really?.... we are in a science show and you are using fahrenheit?
Isn't it amazing? People still use Fahrenheit and still grow up knowing all about Fahrenheit, so it is very courteous of him to use it.
Please use metric scale.. Except for that little detail, I loved the episode
I'm watching a science show... with measurements in Fahrenheit and Mph.
With that aside, thanks for the video! Very informative!
Such an interesting idea for an episode that felt a little bit rushed. Would have liked to hear what the purposes of these materials were. I know we are all sounding like a broken record at this point but the Soviet suits were important too! Still though thanks for making all the other great content.
It's been almost 50 years since man landed on the moon and we're basically still using the same suits. Kind of weird, especially with the advent of newer, lighter and more durable materials. I guess you could say "If it ain't broken, don't fix it." but the limitations of the A7L suit are well known. They were fine for the first few hops across the Moon's surface but nobody is going to want to colonize Mars stuck in one of those.
Great Video! Always wanted to be an astronaut (even signed for Mars One and everything) but, sadly, never will be.
A minor complaint: as per the discussion below, you should really use Celsius and Metric systems for a more worldwide appeal, and greater understanding overall (converting Fahrenheit is a pain).
Honestly though, I'd rather you'd just stop using Fahrenheit altogheter. With all due respect, it's but a fruit of stubbornness, and not using it at all would be a sound statement.
Please include some captions for us non-US viewers! I don't know Miles and Farenheits :)
What is the helmet glass made of and how does it protect them from radiation??
Great episode!! But please give us measurements in Celcius and kilometers per hour!
Totally BOSS!!
I keep thinking of the first diving suits. Is there a possibility space suits will evolve the way diving suits have?
I would like a video done on uranus. Maybe title everything we know about that planet. Not many videos on any channels are done about the ice giants. The ones that exist focus on Neptune.
Its like the Soviet space program did not exist for you people.
I always wanted to wear a spacesuit.
Micrometeorites are one of the least dangerous things I can imagine.
Micrometeoroids, on the other hand, you gotta watch out for those.
Your voice is awesome. Have you worked at narrating? because you should
oo space so intresting
For the record NASA initially had 3 suits, that suit was voted as the winner in a contest.
Hi, could you give temperatures in degree celsius?
how about the terran exoskeleton?
