30 -- Planetary Protection Constraints for Future Exobiology Missions
TWO ORAL SESSIONS
THURSDAY, April 17, 2008: MORNING
Planetary Protection Constraints for Future Exobiology Missions
THURSDAY, April 17, 2008: AFTERNOON
Planetary Protection Constraints for Future Exobiology Missions: Panel Discussion on Microbial Inventory Approaches

Description
In order to search effectively for life elsewhere in our solar system, it is essential that we not bring with us terrestrial contaminants that could interfere with life detection assays, or themselves be confused with extraterrestrial life. To prevent forward contamination of other planets, Planetary Protection includes policies and practices for limiting biological contamination on spacecraft (as developed by international consensus over the last half-century), and research to understand the potential for Earth life to contaminate other solar system bodies. In this session we invite contributions focused on two themes: understanding the propagation of terrestrial life in analogues for other planetary environments, and detailing technological developments in planetary protection implementation and life-detection instruments.
