Questions & Answers

Q: How do astronauts write in space?

Astronauts use specialized space pens that rely on gas pressure to allow the ink to flow in microgravity, overcoming the lack of gravity assistance.

Q: How do astronauts wash their hair in space?

Astronauts use a washcloth to apply shampoo to their hair and carefully rinse it using a small amount of water, all within the confined space of the spacecraft.

Q: How do astronauts use the bathroom in space?

Astronauts use specially designed toilets that rely on air flow and suction to collect and remove waste. They also have to be careful to avoid any splashing in the microgravity environment.

Q: How do astronauts maintain their health in space?

Astronauts have to exercise for about two hours per day to combat muscle and bone loss. They use specially designed exercise devices, such as treadmills and resistance devices, to stay physically fit.
