Answer:
1. New Technologies and Research
Humans did not evolve to go into space, but we go there anyway. That has led to the development of various technologies that feed back into the economy and improve our lives on Earth. Without space programs, we wouldn’t have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras.
2. Humanity's Purpose
Human space exploration helps to address fundamental questions about our place in the Universe and the history of our solar system.
3. Long-term Survival
It is only a matter of time before something happens to our planet that is so devastating that it changes the course of life as we know it. Whether the disaster is natural it is possible that our home will no longer be habitable. What happens, then, to all of the accomplishments of the last thousand generations of humans? All of our art, our music, our literature, our science, even our very genes could be wiped out. Unless, of course, there are a few humans living elsewhere in the solar system. Space exploration and colonization of the Moon and Mars are an insurance policy for humanity and all of our achievements.
