Planetary spacecraft to explore Mars are subject to international and NASA policy regarding biological cleanliness. This policy is referred to as planetary protection and it establishes guidelines to prevent biological cross-contamination of planets during solar system exploration missions. Mars mission designs and exploration strategies are incomplete without consideration of planetary protection. In this paper, the foundation for planetary protection policy will be reviewed and key issues identified. Existing guidelines governing both forward and back contamination will be summarized. Various Mars exploration scenarios will be examined and the impact of planetary protection requirements will be assessed. Technical issues that need resolution will also be identified. Finally, there will be a discussion of anticipated public attitudes concerning the risk of back contamination from Mars sample return missions.
