Finding water on Mars could be a boon for human explorers there, as it provides drinking water, oxygen, and rocket fuel. Dr. Pascal Lee of the Mars Institute and SETI, with his colleagues, has spotted the remains of what appears to be an ancient glacier—which may still contain ice–close to the Martian equator, where it would be most accessible to future astronauts.
