None they use carbon monoxide
So that the astronauts on board can breath, of course. :)
They carry it with them on board.
There is no oxygen in space. Astronauts have to take oxygen with them.
There are several problems met by astronauts in outer space. These problems include oxygen, radiation, gravity, weight, temperature, and food.
No, we cannot breathe in space because the oxygen level is very low. astronauts have to carry oxygen tanks to space.
It controls the temperature there, water and oxygen are also there.
Spacecraft need an internal oxygen supply to provide a breathable atmosphere for astronauts during space travel. Since there is no oxygen in space, spacecraft must carry their own supply to support human life. This ensures that astronauts have the necessary oxygen to breathe and carry out their activities while in space.
Oxygen is needed in our body so we can survive. The cells in our body need it and without oxygen, the cells will die and we will die. When people go in to outer space there is no oxygen so oxygen tanks are taken so the astronauts receive the oxygen they need
so the people can breath
They study how long to get to planets and if there is life in outer space.
