Viking Mission and Evidence of Life on Mars

A former NASA scientist has written that he is convinced that the U.S. space agency “found evidence of life” on Mars in the 1970s, but the data was largely ignored.

The stunning admission by Gilbert Levin—the former principal investigator for the Labeled Release (LR) experiment on NASA’s Viking mission to Mars—came in an op-ed recently published in Scientific American. In the article, the engineer and inventor is clear that he believes he found convincing proof of the existence of living microorganisms on Mars in 1976, but the agency has since been unwilling to acknowledge what he sees as a clear fact.

That's an interesting theory that I had not heard before - makes sense. I also don't doubt that at very high levels there is probably "public policy" pressure along the lines that is frequently theorized, but probably not proven, that the governments would hide evidence of UFO's even if they had it. I don't really believe that there is significant UFO evidence out there, but I don't doubt that governments worry about public reception of evidence if it came their way.
