Question

what is space technology and why it is risky to send humans to space?

Answer 1

Answer:

Space technology is technology developed by space science or the aerospace industry for use in spaceflight, satellites, or space exploration. Space technology includes spacecraft, satellites, space stations, and support infrastructure, equipment, and procedures and space warfare.

5 hazards of human spaceflight:

1. Radiation

2. Isolation and confinement

3. Distance from Earth

4. Gravity (or lack thereof)

5. Hostile/closed environments

The environment of space is lethal without appropriate protection: the greatest threat in the vacuum of space derives from the lack of oxygen and pressure, although temperature and radiation also pose risks. The effects of space exposure can result in ebullism, hypoxia, hypocapnia, and decompression sickness.
