They take a massive oxygen tank with them.
Astronauts travel in space and escape earth's atmosphere by wearing gravity resistant suits and traveling to outer space in a space shuttle that is insulated against the elements.
The Apollo 13 astronauts were not on the space shuttle.
Astronauts aboard the space shuttle were primarily NASA astronauts, astronauts from Canada, Europe and other countries.
none. The Challenger exploded low in the atmosphere and Columbia burned up like a meteor high in the atmosphere. Neither were in space.
We will assume you are asking about the Space Shuttle, a reusable spacecraft flown by NASA. While the shuttle is lifting off and in the atmosphere any sound generated by the shuttle will travel through the air. When the shuttle is in orbit there is no (or very very little) air and any sound that would have been generated by the shuttle will not be transmitted. There is a pressurized atmosphere within the shuttle that allows the voices of the astronauts to travel within the shuttle just as it does on the surface of the Earth.
Astronauts
At what altitude does the Earth's gravity no longer have an effect on the astronauts or the space shuttle?
Yes, the remains of all seven astronauts aboard the Space Shuttle Columbia were found following the tragic disintegration of the shuttle upon re-entry into Earth's atmosphere on February 1, 2003. The investigation recovered personal effects and human remains which were returned to their families for burial.
Astronauts don't hit their heads on the ceiling of a falling shuttle because they experience microgravity, which creates a sensation of weightlessness. In this state, both the astronauts and the shuttle are in free fall together, moving at the same rate and direction. This means that there is no relative motion between the astronauts and the shuttle interior, preventing them from contacting the ceiling.
yes there are
they have a space shuttle for a reason
