Question

What's the hardest part of space travel?

Answer 1

Space travel

1. Many astronauts agree that going to space is one of the most difficult things they have ever done.
2. Learning to use the spacesuit was one of the most difficult aspects of space training because the suit must be relatively thick in order to protect them from the harsh environment of space (vacuum, radiation, micrometeoroids, and severe temperature).
3. While performing a spacewalk, body movements are restricted.

The following are some of the most difficult aspects of space travel:

1. The pull of gravity: To fly free of gravity's grip, one must travel at a speed of more than 25,000 miles per hour.
2. Once we leave the earth's atmosphere, particles travel at the speed of light towards us, and the air in space can cause cancer, cataracts, and Alzheimer's disease.
3. Landing on the ground would be tough because there is no way to crash.
4. Temperature is the primary threat in space. It can be very cold (in shadow, not in the line of sight of the sun 150°C) or extremely hot (in line of sight of the sun +120°C).
