They carry liquid oxygen with them in their capsule. CO2 is removed through filters. Don't ask where their drinking water comes from.
Astronauts bring tanks of oxygen with them when they go into space. The space suits they use to make space walks also have small oxygen tanks on them.
There is no oxygen in space. Astronauts have to take oxygen with them.
A suit, a rocket or brought oxygen maybe?
Liquid oxygen and liquid hydrogen are used as rocket fuel, oxygen gas is used by the astronauts to breath.
Astronauts cannot survive without oxygen; they rely on life support systems in their spacecraft or space suits to provide a continuous supply of breathable air. These systems use tanks of compressed oxygen and can also recycle carbon dioxide exhaled by astronauts. In emergencies, astronauts can use backup oxygen supplies to ensure they have enough air to breathe. Without these systems, they would quickly suffocate in the vacuum of space.
None they use carbon monoxide
Astronauts use compressed oxygen mixed with nitrogen fo produce their breathing gas.
They need to take it with them. There is no oxygen in space
Astronauts wear spacesuits that are equipped with a life support system, which includes an oxygen supply for breathing. This system provides them with a controlled environment to breathe while they are in the vacuum of space.
They carry it with them on board.
Their suits-similar to divers.
No, astronauts cannot breathe on the moon because there is no atmosphere. It lacks oxygen and air pressure required for humans to breathe. Astronauts must rely on oxygen supplies within their spacesuits or habitats.
