The latest presentation to the Future In-Space Operations (FISO) study group is now posted in the FISO Working Group Presentations Archive. Both slides (pdf) and audio (mp3) are available for the talk, NASA’s Planetary Protection Policy for Mars Exploration – Planetary Protection Part 2 – Cassie Conley, NASA HQ – August 7, 2013

Conley talks about how to avoid contaminating Mars with earth bacteria before we know if there are any native Martian bacteria and vice versa. Don’t see any discussion of the exchange of life forms between earth and Mars via debris expelled via large impacts. (See Martian meterorites.)
