They have oxygen. And they float. Unlike your brain.
They can't breath and start to chock up and there muscles get tight!!
Yes, they carry a finite supply of breathable oxygen in oxygen tanks that they wear on their backs during spacewalks
they eat him.
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.
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
Oxygen (O2) is necessary to the respiration and the survival of astronauts in the near vacuum of space. Astronauts does not have the breathable atmosphere on Earth in space. The space suit protects them from the lethal cold and vacuum of space by keeping him in temperature controlled and pressurized environment.
yes. the space suit does protect astronauts for harmful rays from the sun
they need oxygen, food, water, spaceship, and a heat source to survive!
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.
gravity and oxygen
In space, there is no gravity to overcome. The chllenge to astronauts is how to deal with the lack of gravity.
There are several problems met by astronauts in outer space. These problems include oxygen, radiation, gravity, weight, temperature, and food.
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
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.
no because there is no air in space their is less gravity so need to wear special outfits
Yes, astronauts can fly out here and there as they live in zero gravity in space.
