RE: [meteorite-list] sterilizing that probe...!
Hi Ethylene Oxide was rejected as a viable sterilization method on the Viking lander missions, so am I right in assuming they (NASA) have changed that idea? (It's just that they found viable microorganisms after treating with Ethylene Oxide...) Mark Ford -Original Message- From: stan .

[meteorite-list] sterilizing that probe...!
Hi, Somewhat off-topic I know but... I have been trying to figure out how one can sterilize these various Mars probes, knowing how tenacious life can seem to be. Surely NASA cannot be seen to contaminate the (potential) Martian biosphere and there is a lot of hardware that needs to be quite literally 100% sterile - otherwise, how would one know whether or not the signatures of life that may be found were not terrestrial in origin? How on Earth does one sterilize Mylar, for example? Unknowledgebly yours dave IMCA #0092 __ Meteorite-list mailing list [EMAIL PROTECTED] http://www.pairlist.net/mailman/listinfo/meteorite-list
