The rare meteorite that fell in the Sierra foothills this spring yielded a rich harvest of scientific data.
On November 8th, at 3:28 PM PST, the asteroid "2005 YU55" will pass by the Earth at a distance of just over 200,000 miles, or about 40,000 miles within the Moon's orbit. Fortunately, the asteroid's trajectory is well known, and poses no threat to us (at this time).
A recent publishing of the investigation of a rare class of meteorite (the CI1 Carbonaceous Chondrite) by Dr. Richard Hoover of NASA's Marshall Space Flight Center has caused another stir among scientists and the news media regarding possible origins of life on Earth and life in the Universe in general.
On Monday, November 30th, 2009, NASA/Johnson Space Center announced that a recent study strengthens the argument that chemical and structural features in a Martian meteorite—ALH84001—may be evidence of fossilized microbial life on Mars from the distant past.
Why is it that meteorites are brought to me for identification in clusters? I don't mean that people bring clusters of meteorites-but it seems I get calls and visits from possessors of unknown rock samples, hopeful that they are of extraterrestrial origin, in bursts. This time I got two inquiries in two days!
