The oxygen is a simple matter: they simply take it with them when they leave Earth. Humans can survive being weightless for a few months with no lasting effects on their health.
In space, there is no gravity to overcome. The chllenge to astronauts is how to deal with the lack of gravity.
No one knows, but typically astronauts do not stay in space for more than 1 year. Otherwise, the zero gravity will degrade their bones and muscles
The Apollo 13 astronauts were not on the space shuttle.
They have a rocket; spacecraft that has oxygen filled in it. They wear belts to make themselves sit. hope it helps, Kayla
Yes. Gravity is what keeps them in orbit. If it were not for gravity, those astronauts would continue out into space in a straight line.

There are several problems met by astronauts in outer space. These problems include oxygen, radiation, gravity, weight, temperature, and food.

They have oxygen. And they float. Unlike your brain.
There is no gravity in space.
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.
Well, there is no gravity so you float around and there is no oxygen, that is why astronauts wear special suits when they go up there.
Yes, astronauts can fly out here and there as they live in zero gravity in space.
no because there is no air in space their is less gravity so need to wear special outfits
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
