The astronauts breath as they have an oxygen tank which they keep attached with their space suit.
They actually take enough oxygen with them to enable them breath.
Which is quicker? Heat or Cold!!! 'Heat, because can 'catch (a) cold'.
They breathe air, which contains oxygen. They do not breathe hydrogen, as it is a bad idea to mix hydrogen and oxygen unless you intend to create anexplosion.
You are conscious, but you can breath-i think.
your breath
yes we can breath in the space station
Space Is Infinatly Big
no you cannnot breath in space because there is no oxegen , but there was ice found on mars which means we can make O2 , because there is oxygen in water. But if you hold your breath in space then you will explode jue to the impact (:
because people need oxygen to breath, in space there is no oxygen making people ineligible to breath.
they have air tanks in their space suits
They actually take enough oxygen with them to enable them breath.
with oxygen tanks
You but them in a spacecraft with oxygen in it
The air in the space shuttle is pressurized, the whole thing has air in it to breathe.
it has Scuba tanks of oxigen.
No you can not only if you can breath in space
Astronaunts have to wear space suits so they can breath when they are off the surface of the planet. They NEED the space suit to survive in places such as the moon so they could breath. They don't only need it to breath, but for temperature issues. On some planets, it's extremely hot or cold, so how could they survive on that? That's what the space suit comes in handy for. ;]
