Did Viking Lander Kill Alien Life?
Jan. 8, 2007 — Two NASA space probes that visited Mars 30 years ago may have stumbled upon alien microbes on the Red Planet and inadvertently killed them, a scientist theorizes in a paper released Sunday. The problem was the Viking space probes of 1976-77 were looking for the wrong kind of life and didn’t recognize it, the researcher said in a paper presented at a meeting of the American Astronomical Society in Seattle. This new report, based on a more expansive view of where life can take root, may have NASA looking for a different type of Martian life form when its next Mars spacecraft is launched later this year, one of the space agency’s top scientists told The Associated Press.
