- NASA has adopted the COSPAR guidelines on planetary protection and i believe
- even has an office for this. They are concerned about contamination in
- both ways. They reccomend, heat sterilization, radiation, gas and chemicals.
-
- The big concern now is not so much establishing earth organisms on foreign
- bodies, but destroyin/contaminating archaeology studies of exo-biology.

- I know the Mars Observer orbit was constrained under planetary protection
- guidelines to stay off the surface for X thousand years.
