It didn't. Space does have some oxygen, it is just extremely thin almost everywhere (except in the atmospheres of some planets).
Humans lose consciousness when the oxygen supply to the brain gets low.
If you kept moving up into space without any type of spacecraft or protection, you would eventually reach a point where the lack of air and pressure would cause your body to lose consciousness due to lack of oxygen. Continued exposure to the vacuum of space without a space suit would ultimately lead to death.
Oxygen is used in the launch of space vehicles to make discoveries.
They carry it with them on board.
Space junk, stars, planets and no vacums Nij ok???
The suit might lose oxygen and the astronaut could suffocate.
Simple: People cannot stay in space for a long time because although they have stored oxygen, it cannot last forever. Eventually they will lose all oxygen, and if they have not returned to earth before their oxygen runs out, they will die.
No, you do not explode in space. In the vacuum of space, there is no air pressure to cause your body to explode. However, without a spacesuit, you would not be able to breathe and would eventually lose consciousness and die due to lack of oxygen.
They need to take it with them. There is no oxygen in space
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.
The space shuttle is able to fire its engines in space because it takes the needed oxygen with it.
There is no oxygen in space. Astronauts have to take oxygen with them.
In space there is no oxygen. Space is a vacuum. All things like a rocket going to space, require a fuel to burn, oxygen and a heater. Since there is no oxygen is space they need to provide it for them. Meaning the reaction can take place correctly.
There is no oxygen in space and fire needs oxygen.
While space itself does not have oxygen, astronauts have access to oxygen on space missions through systems that generate and regulate the supply of breathable air. This is necessary for them to survive in the vacuum of space.
Oxygen tanks and space suits are needed for space exploration because there is no air in space and anyone there without suitable coverings and sources of oxygen would quickly die.
Fire needs oxygen in order to burn, and there is no oxygen in space, so rockets must take oxygen with them.
