i think that astronauts usually get about six hours of sleep every night when they are in space.
Less than 8 hours.
Astronauts require less sleep than normal; Theoretically because the astronauts always have to be alert in a dangerous setting like space.
the things that astronauts do on a mission is sleep learning how to fly a space shuttle
The Space Station and Shuttle astronauts keep Houston time, and sleep when it's night time in Texas. In the old Soviet-era Mir space station, the cosmonauts kept Moscow time. However, I believe that like ships, the ISS and Shuttle astronauts keep "watches", so that someone is awake at all times.
Astronauts sleep in a vertical position by strapping themselves into sleeping bags that are attached to the walls of they're sleeping compartment.
Less than 8 hours.
They get less than 8hrs. only about 6hrs. of sleep
Astronauts typically sleep around 8 hours per day while in space. However, the actual amount can vary depending on their schedule and workload.
They should usually have around 9 to 9 + a half hours sleep per night.
8-9 hours
When it's tired.
Work hours of astronauts on missions vary, and they do not have the 24-hour days like us. But this is the closest answer of hours in a week you will come: Work: 50-66,5 Exercise: 17-20 Sleep: 56 Hygene/Eating: 18-21 Personal Time: 10,5-21
It depends on the individual.. I'm slightly older, and I usually have around 6-7 hours a night, depending on how tired I feel.
The U.S. astronauts go to sleep in their spacecraft in their sleeping bags , all tied up neatly. the sleeping time is according to the Houston night time, the Russian sleep according to Moscow time.
