Last Video: The SpaceX Starship SPACE STATION Is Coming!

Mars Colonization News and Updates

The Space Race is dedicated to the exploration of outer space and humans' mission to explore the universe. We’ll provide news and updates from everything in space, including the SpaceX and NASA mission to colonize Mars and the Moon. We’ll focus on news and updates from SpaceX, NASA, Starlink, Blue Origin, The James Webb Space Telescope and more. If you’re interested in space exploration, Mars colonization, and everything to do with space travel and the space race... you’ve come to the right channel! We love space and hope to inspire others to learn more!

i do however wish people will compare the space x suits to other suits that are in the same category and not just the exterior suits made

Explains the difference between IVA and EVA suits ✅

Talks about NASA "pumpkin" suits but shows B-roll of an EVA suit❌

[smetz]

Very frustrating & misleading; despite starting with a quick IVA vs. EVA definition, it's wrong to repeatedly compare the minimalist safety suit of the Dragon to all the past and future NASA designs made for long-term work shifts outside the ISS that require rugged gear and complete stand-alone environmental life support. And suits that can fit a big range of folks on station is a plus too. SpaceX is doing awesome stuff with innovative designs, but don't misrepresent the huge additional challenges that NASA spacewalk workers must face which sheltered Dragon passengers do not.

[infinite_monkey]

Virtually EVERY time other "flight suits" are mentioned, the video actually shows some form of EVA suit.

[mikemccormick]

I have a similar complaint that lestagez described. You are comparing the SpaceX IVA suit to the NASA EVA suit. Why not compare the SpaceX IVA suit to the NASA Space Shuttle orange jumpsuit (IVA)?

[FranckMartin]

You forgot about cooling, dealing with temperatures outside the vehicle is more challenging than inside.

[Asterra]

The biggest flaw/drawback of the SpaceX suit is the helmet. You get zero flexibility to swivel or crane your head, and this is compounded by a visor design that limits field of view more than pretty much any other suit design. I like to think that SpaceX are aware of these shortcomings—especially as they contrast with competing designs such as the one intended for the now-almost-defunct Starliner—and will be addressing them when it comes to the actual EVA suit. Other than that, yeah, the SpaceX suit _especially_ puts the hopelessly out of date taikonaut suit to shame. I like to think China is torn on just how much of SpaceX's suit design they should steal.

There is already a fantastic fabric made from UHMW (Ultra High Molecular Weight polyethylene) that, by the nature of the very long molecule strands, offers high tensile strength without sacrificing flexability. I've used an 8 way woven version of it with a very thin layer of UHMW heat set to the back in epoxy encapsulating applications where it gets drawn under a near perfect vaccum, then pressurized to 20 to 25 PSI. The vacuum removes all the air from the area receiving the epoxy, then the epoxy is introduced to the space in a way that it fills all of the small areas of the cavity. Once the cavity plus the overflow space is full, the system is then pressurized to compress any voids or air pockets that formed. This squeezes any air pocket down to less than 1 percent of its volume while in a vacuum. It's a fantastic system made possible by the UHMW fabric. An additional bonus property is that noting sticks to the UHMW, so wear and cleanup was a breeze. I think this property would translate over to a lunar EVA suit very well to reduce suit wear due to the lunar dust.

[Rorschach]

Even better than polyethylene fabric would be tungsten coated polyethylene. If the thread had tungsten sputtered onto it before being woven then the shielding value would go up quite a bit. Tungsten is even better than lead for gamma/x-ray shielding. Polyethylene is good for neutrons but not for gamma or x-rays combining the two is critical.

[MrSmithwayne]

we are truly living in an age of wonder when so many technologies and human exploration all coming together. If we can get rid of all these endless pointless wars and remove the people wanting this then humanities boundaries will rise even further.

[peterclarke]

I think it’s great that they got a Hollywood costume designer to design the appearance of these spacesuits.
Engineers then reworked the original fabric design, into a functional space suit.

[stevebartlett]

Your video is filled with inaccuracies: You compare SpaceX IVA suits with NASA EMUs and Russian Orlan suits - both of which are EVA suits. If you were doing a fair comparison you would have shown the orange Shuttle ascent flight suits. An actual EVA suit has to provide a far greater range of motion, operate for hours, provide MM/OD protection, deal with varying light levels and themal conditions, allow for bending without fatiguing the wearer, etc. The SpaceX suits are simpler and cheaper because they don't have to do as much. But put them in a real working environment where you can't tailor every suit to a single user and they get much more complex and expensive.

[i-craftsdesign]

In the moon they'll have to use the cocoon style the russians lunar suit had. When they slip out after a moon walk there should be a spray or vaccuum system where the back of the suit docks into entry airlock so that it blows away regolith.

7:50 there were Gemini and Apollo missions that orbited higher than that.

[danwhiffen]

3:40 . Technically this process wouldn’t be reverse engineering. Reverse engineering is trying to figure out how something was engineered by someone who didn’t do the original design. It’s really just regular engineering what they did. Analogous to an architect ‘designing’ a building and the engineers figure out how to make it work.

[joelgreen]

This video is confusing IVAs (Intervehicular Activity) with the EMUs (Extravahicular Mobility Unit.) These are two very different technologies. With NASA holding a competition for the best IVA.

[videolabguy]

1:52 - INCORRECT! The Soviet center cosmonaut had a literal "faucet" between his legs that he was required to close manually. They missed that step on the check list and accidentally committed suicide. This was a procedural error caused by central planning control freaks and not a hardware malfunction. The valve worked perfectly when tested after the landing.

[EthosAtheos]

Almost none of the suits you showed were space flight pressure suits for launch and reentry (NASA ACES). Almost everything you showed off was an EVA suit. Try doing an EVA in a pressure suit and I think you'll have a bad day. NASA's ACES suit has about 10 min of air in it, SpaceX's suit looks like it has even less.

[mcdoctorglock]

I'm wondering why mechanical pressure suits aren't looked into more; the only part that would have to be pressurized would be the helmet, saving a lot of air and lengthening flight times.

[mikejetzer]

Comparing how easy it is to get into a SpaceX pressure suit vs. how hard it is to get into a NASA EMU ...
