Startups like AstroForge want to mine asteroids instead of Earth, which would mean an effectively unlimited supply of raw materials that are rare on Earth. The extraction of valuable minerals has led to a host of problems, including environmental damage and human exploitation, but there’s a wealth of precious materials in space. NASA is currently making plans to run a spacecraft into an asteroid to test one possible method of saving Earth from such an impact.Īs the population continues its inexorable upward climb, the strain on our natural resources continues to increase. If we’re not working toward that goal, humanity already has an expiration date. A robust space program is the only hope we have of deflecting such an object.

Speaking of saving lives, space exploration could save all our lives. 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. ![]() Without space programs, we wouldn’t have GPS, accurate weather prediction, solar cells, or the ultraviolet filters in sunglasses and cameras. That has led to the development of various technologies that feed back into the economy and improve our lives on Earth. Humans did not evolve to go into space, but we go there anyway. ![]()
