LIFE ON MARS, REBORN

摘要

In April, Kathie Thomas-Keprta told a standing-room-only audience at the Astrobiology Science Conference that she had found evidence of life on a three-billion-year-old Martian meteorite. And no one was surprised. That's because she and eight other researchers at several universities and NASA's Johnson Space Center had reported the same thing about the same meteorite in 1996. They were met with criticism and ridicule back then. But this time, the reaction was more favorable.
