The Evolution of Space Technology

A lot of things that space is hoping to address and to figure out so we can expand as a species into outer space. How do you feed people if you're building a lunar permanent base? HowDo you shelter people on Mars? How do you grow food sources? If we could figure out how to do it in space, there's a really good chance that we'll actually be able to take that technology right back and use it on Earth. That might be able to help us in many ways that we don't actually realize today.
