Life on Mars (Digital Audiobook)
What to Know Before We Go
Publication Date: May 7, 2018
David Weintraub tells why, of all the celestial bodies in our solar system, Mars has beckoned to us the most. He traces how our ideas about life on Mars have been refined by landers and rovers, terrestrial and Mars-orbiting telescopes, spectroscopy, and even a Martian meteorite. He explores how finding DNA-based life on the Red Planet could offer clues about our distant evolutionary past, and grapples with the profound moral and ethical questions confronting us as we prepare to introduce an unpredictable new life form-ourselves-into the Martian biosphere.
