Description

Are we alone in the universe? Mars was once habitable - so could we be Martians or Martians be Earthlings? Setting foot on the Red Planet could help us uncover these and more questions. NASA 360 joins Dr. John Grunsfeld, former Associate Administrator for NASA's Science Mission Directorate, as he discusses the potential for life on Mars and what it will take to make such a discovery. This video was created from a live recording at the Humans to Mars Summit in May 2016. To watch the original talk please visit https://livestream.com/viewnow/exploremars2016
