If they lose their grip on the station while spacewalking and have somehow forgotten to properly clip their tethers on, they will float away. Both US suits are equipped with SAFER packs, which are small rocketpacks that can be used to jet back to the station, or to rescue a crewmate. They haven't had to use them yet, but they have tested them out in space, and all US spacewalkers are trained to use them in simulators on the ground.
This could be a good plot for a space horror movie! 0:23 - Imagine if those water specks inside helmet started to move towards each other, forming a bigger water speck, and then "space terminator" began to appear from that puddle, filling the space suit from inside as other astronauts watch this in horror! Hey James Cameron, if you're reading this, you owe me a percentage from earnings if you make this movie! :)
Unless you have propulsion or something to grab onto there is no way to change your translation in microgravity. You can change your rotation by bending and contracting your body, but you cannot go in any direction by moving yourself. Translating by grabbing surfaces and using them to propel yourself is pretty straightforward and doesn't really need specific lessons. You don't need a lesson for grabbing and moving around the edge of a pool.
yes but the LCGV system include crash resistant pipes. i assume that the hole story is not an accident but a product construction check fail. i mean that there should be a problem that it was easy to see but nobody payed attention.. If that man have died then i cant imagine what kind of humiliation nasa would have..
Laughing !!! Where the heck is the seal on the helmet ????? Wouldn't it need to withstand high pressure when pressurised before going out ???????? Surely that's not the real helmet ???? I also thought the cooling water was in the vest under the suit, surely you could drown easily if it splits ." Why on earth use water ..... Sure I could think of a better design. Is this real or just a re-make of the actual suit and event ?
+Brandon Howard I just spent some time researching this - this is the actual suit and helmet worn when the leak took place, however they are (obviously) powering up the suit from the interior of the ISS to see if the issue was still present and for recreation purposes to narrow down the specific parts that are causing the problem. The cooling water is inside / under the suit, however it looks like it somehow leaked and made it's way into the ventilation, up the suit and travelled into the helmet where a vent is present. Apparently, nothing like this has ever happened before, which is why they were attempting to find out how it even occurred. I can't imagine how terrifying that must have been.
+FastFacts Online This happened twice, with a different kind of issue occurring with Col. Chris Hadfield. The Colonel had anti-fog liquid come off his visor and get in his eyes, blinding him.
+Brandon Howard The seal is in the neck ring. You can see the astronaut press the release, which likely expands the locking ring inside, opening the seal and widening the diameter of the helmet collar for removal. When this happens, the seal is opened.
The EVA suit is pressurized to about 5psi... Space is Vacuum; 0psi... 5psi differential is very far from being high pressure. Why use other kind of cooling fluid that could be dangerous for the astronaut when you can use water that is safe for everybody... Water is safe for the eyes of the astronaut and worst case scenario he can drink it without any danger.
I love these videos. Gives you a real sense of the research they are doing and what daily routines are like.

I am a new viewer but I want to say Thank You to NASA for these videos.

did he get to say, "Houston we have a problem?"
tears for spheres
Walt officially have the most boring life here on earth while they're being super heroes up there lol
The astro-not whose helmet filled with water should have called on Aqua-man before his fears of seeing space-ghost............
7 years ago, wildfires in US.
Well said.
Is closed captioning available? I'd like to show this in my coffee shop with the sound off. AngryRobotCoffee com
Kind of scary how easily the helmet comes right off like that. Seems like you could accidentally bump that piece and your face depressurizes...
Starfish Prime - watch again; at 1:37 he had to unlock the ring first. Until it's unlocked it cannot be easily separated.
do you have to learn to move around in "zero" gravity like swimming???

oh that explains alot but what if there like stranded in space how will they move about...do they don't?
They don't
WHERE water cAME FROM ??????????????
mitropoulosilias cooling system
cooling what??
These are pipes arranged around the astronaut to keep his body at the right temperature

there is also a drinking straw
Reelnasa seems legit
and too much can kill you I am flagging this suit as broken and the crew will have to ship it back to Houston on Dragon 4
there's the smoking gun just ship the whole suit back to Houston and send up a new one

And your point is?
Lol 0g hair
Does it say anywhere that you're not allowed hair ties in space? because all of her hair is annoying me.....
and apparently her husband is also high rank military astronaut so.....
Hightech made in China...lol
