6. Which of the following is false concerning NASA's interest in a p is false concerning NASA's interest in a possibility of Martian life? A. The interest was originally sparked by internal features of meteorite ALH 84001(the oldest of about 50 known mars-derived meteorites). These features included bacterial fossil-like structures, complex organics, and magnetite structures like that produced by magnetotactic bacteria on earth. NASA recently announced discovery of organics in >3 billion y/o “mudstone." They also reported "seasonal" spikes in...
