Meteorites from Mars and on Mars

Location: Geology 3656
Time: 2:30PM

Martian meteorites are key sources of information about the Red Planet, especially its volcanic history. Ar and N isotopic ratios show the martian connection. Even though there are fewer martian meteorites (about 110) than lunar meteorites (140), the tally for meteorite falls is 5 martians to zero lunars. Rovers have analyzed a few meteorites among the cobbles on the martian surface. Photo credit: Ron Baalke
