Why do spacecraft have airlocks?
Humans need air to breathe, space is a vacuum so the atmosphere inside the spacecraft needs to be separated from the vacuum outside. Once in a while an astronaut needs to go to the outside of the spacecraft to perform tests or maintenance, and the airlock provides a way for him to go outside without losing the air from the inside. He enters the airlock and closes the door, then all the air inside the airlock is sucked out so it can be used ( air is a precious commodity in space ) then he can open the door to the outside without losing any of it.
How fast does a person travel in space when outside of spacecraft?
10000 km an hour
Why do astronats have to whaer pressurized space suits when thay are working outside the space shuttle?
Because space is like a vacuum. If they went outside of their spacecraft without a pressurized suit, their bodies with stretch like putty.
What is the act of moving around in space outside a spacecraft called?
Extra Vehicular Activity or EVA Also commonly referred to as a space walk.
What is a launch of a spacecraft?
The process by which a spacecraft is propelled into space.

When astronauts travel in space they must wear special helmets. Why?
The helmets are part of their space suits. They do not normally wear space suits unless they are going outside the spacecraft. Since there is no air outside and it can be very cold or hot. They need the suits to breathe and to protect them from the heat or cold and the vacuum of space which would kill them.

Why astronauts wear space suits outside spacecraft?
If they don't they will suffocate from lack of oxygen in space.
Are you capable in listening when you are in space?
Only to those sounds inside the pressurized space suit or spacecraft you are in.

Why should a spacecraft be space-tight?
Any suddenly opening appearing in the skin of the spacecraft would allow the atmosphere inside the craft to escape out into space - causing decompression.
How does an astronaut get CO2 to breathe in space?
Astronauts breathe O2, just as we all do. There are life support systems on spacecraft and on the Space Station that provide oxygen and absorb CO2. On the Space Station, there is an oxygen generator, as well as a water recycling system.
Do astronauts have have to wear the space suits all the time?
No, they only have to wear these when outside the pressurized environment of the spacecraft or during periods when the spacecraft may become compromised.
What are astronouts?
Astronauts are people who travel in space.
Why do space rockets carry a source of oxygen?
There is no oxygen in space, so spacecraft must carry oxygen with which to burn their fuel and, if they are manned, to allow the crew to breathe.
