To get into space, we have to practice at home. That’s the idea behind NASA’s Earth Analogs program, which tests people, ideas and technology at a variety of inhospitable places around the world. Finding places on Earth with physical similarities to space sites isn’t easy – but the space agency has located desert, volcanic, arctic, lake and ocean locations for testing all manner of things.
