Updated March 17, 2001 | All last week, attendees at the 33rd annual Lunar
and Planetary Science Conference in Houston, Texas, looked forward to one of
the meeting's final sessions, whose main attraction was the controversial 4
1/2-billion-year-old Martian meteorite known as ALH 84001. For years David S.
McKay (NASA/Johnson Space Center) and his coauthors have maintained that this
celebrated stone contains strong evidence — but not proof — of fossilized
microbial life.
