Are we alone in the universe?
Leading scientists still have no idea:
It was arguably the space agency's most imagination-gripping moment since Apollo. Space buffs and NASA officials said that it just might be the scientific discovery of the century."If the results are verified," the late Carl Sagan pronounced, "it is a turning point in human history."
Ten years later, the results have not been verified. Skeptics have found non-biological explanations for every piece of evidence that was presented on Aug. 6, 1996. And though they still vigorously defend their claim, the NASA scientists who advanced it now stand alone in their belief.
"We certainly have not convinced the community, and that's been a little bit disappointing," said David McKay, a NASA biochemist and leader of the team that started the scientific episode.
But even though the majority of his colleagues don't buy his "life on Mars" theory — McKay's own brother, also a NASA scientist, is one of his most prominent critics — many say they respect him and greatly appreciate his efforts.
