The highest degree of Planetary Protection (PP) applies to landed planetary missions and sample return missions. To date, Dry Heat Microbial Reduction (DHMR) treatment is the only NASA approved PP technique for meeting the stringent sterility requirements for life detection missions and to prevent forward contamination. However, spacecraft (s/c) and payloads are made up of a diverse set of man-made...
Lander missions and sample return missions (Class IVa and Class IVb) require the highest degree of planetary protection (PP). To date, dry heat sterilization is the only NASA approved PP technique for meeting the stringent sterility requirements to prevent forward contamination. However, spacecraft and payloads are made of a diverse set of materials and components which are heat sensitive or incompatible...
