As there is no air out there they have to wear these preassigned suits to adjust to weightlessness and when they return the sudden change will cause problems.
yes
so they can breathe
No, not in space. Sound needs air to travel through, and there's no air in space. However, while they're inside their spacecraft, the capsule is kept full of pressurized breathable air, just so they don't have to wear their space-suits all the time. Since they do have air inside, they can converse without radio while they're in there.
astronauts wear special helmets and clothing that contains human air in it so the human can breath.
They wear space suits
Yes astronauts will have to wear their pressurized suits , when they walk in space.
A pressurized space suit.
yes
Yes. Not under their space suits, but in the pressurized space station and the crew decks of the Shuttle.
They need air and an atmospheric pressurized environment.
Well since there is no atmosphere you'll need to wear a space suit that is pressurized and you need a oxygen tank
No, they only have to wear these when outside the pressurized environment of the spacecraft or during periods when the spacecraft may become compromised.
yes. the space suit does protect astronauts for harmful rays from the sun
so they can breathe
they wear special made shoes....YOU will never be able to buy it hahaahahh.
Yes and they had better be special clothes under your space suit
The earth has a special ozon layer that protect us from the sun.
