What time is it on the moon? One small step for lunar timeīut meteorites remain vanishingly rare, and those from specific locations like the moon and Mars even more so.Midwest, Ontario registers 2.0 magnitude tremor Such scientific scrutiny also helps stem the proliferation of bogus space rocks, or what Pitt calls “meteor-wrongs.” “Only then is it a Martian meteorite or a lunar meteorite,” he says.
