About 6 months at a time and in the Russian program 1 year
It depends on the mission actually. It can be weeks or months even a year! However, the problem is when astronauts goes back on Earth. Getting used to gravity again which would take a while depending on how long they stayed in space.
This will depend on how long the space mission is planned for.
It depends on how long their mission is. Normally ranging from 10 days up to a few months but not much longer than that because staying in an enviroment without gravity for too long can weaken the astronaut's muscles. It also depends on how much oxygen and food is taken into space with the space ship.

It takes astronauts about 8 1/2 minutes to get into space. However, it takes about three days for them to get to the moon, and about 2 days for them to get to the International Space Station.
it matters what the temperature is in the space where the ice is being melted
how long can garter snakes stay under water?

a year
Yes, approximately. Because of higher velocity, astronauts age slightly less than their counterparts on earth, when they are in space, but only by a tiny amount.On the other hand, weightlessness and radiation contribute to bone loss and other ill health effects; so it might be said that even though time is slightly slowed-down for astronauts, they can suffer a deterioration of their health.
