Through addressing the challenges related to human space exploration we expand technology, create new industries, and help to foster a peaceful connection with other nations.
Beside above, is space exploration really necessary?
Without space programs, we wouldn't have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras. There's also medical research happening in space right now that could cure diseases and prolong human lives, and these experiments can't be done on Earth.
What are the positive effects of space exploration?
Some of the more direct benefits of space exploration include an increase in the knowledge that is out there about space and the discovery of distant planets and galaxies, it also gives us insight into the beginnings of our universe.
What are the negatives of space exploration?
5 Hazards of Human Spaceflight
- Radiation. The first hazard of a human mission to Mars is also the most difficult to visualize because, well, space radiation is invisible to the human eye.
- Isolation and confinement.
- Distance from Earth.
- Gravity (or lack thereof)
- Hostile/closed environments.
