Liquid oxygen and liquid nitrogen are carried on board in two systems of pressurized tanks. The cabin pressurization system combines the gases in the correct mixture at normal atmospheric pressure. While in orbit, only one oxygen system and one nitrogen system are used to pressurize the orbiter. During launch and landing, both systems of each gas are used.

yes. the space suit does protect astronauts for harmful rays from the sun
How do they breath in space?
The astronauts breath as they have an oxygen tank which they keep attached with their space suit.
What is an astronauts backpack?
It controls the temperature there, water and oxygen are also there.
Why should the astronauts use a spacesuits and helmet while walking in the space?
Astronauts wear spacesuits due to the absence of pressure in space. They need to maintain the pressure level on Earth by isolating themselves from actual space. For the helmets: there is no oxygen in space. Humans require oxygen to live, inhaling it through their nose and mouth. Therefore if they do not wear helmets, they will die instantly from loss of oxygen.
How will astronauts get oxygen out of space?
They need to take it with them. There is no oxygen in space
What type of oxygen is in outer space that make us use helmets?
There is no oxygen in space. Astronauts have to take oxygen with them.

How do astronauts get oxygen into space?
They carry it with them on board.
What do astronauts take to space?
A space suite
Do astronauts wear space suites to protect themselves from sun rays or are used for oxygen?
yes. the space suit does protect astronauts for harmful rays from the sun
How and what do the astronauts breathe on the space station?
They breathe a combination of oxygen and niteragine gas in space.
Canwe breathe in space?
No, we cannot breathe in space because the oxygen level is very low. astronauts have to carry oxygen tanks to space.
Is there any difference between air and space?
air (oxygen) does not exist in space. that's why astronauts have suits with oxygen tanks.
What do astronauts use in space?
A suit, a rocket or brought oxygen maybe?
What is used in a space suit to keep astronauts on the moon?
gravity and oxygen
