Kring expects that some geologists in the scientific community won’t accept the finding because it seems controversial. The center is part of NASA’s Solar System Exploration Research Virtual Institute. Under a microscope, anorthosites, the distinctive white rock that made up the moon’s ancient crust, stand out from darker volcanic basalt. David Kring, principal investigator for the Center for Lunar Science and Exploration, challenged his team to find a bit of Earth on the moon. The international research team that analyzed the rock developed techniques to find impact fragments in the moon’s soil. So when the Apollo 14 astronauts collected it almost exactly 48 years ago – between January 31 and Febru– they thought it was an organic sample that would provide information about the moon and its composition. NASAĪsteroid impacts on the Earth and moon have increased since the dinosaurs lived Six missions landed on the moon: Apollo 11, 12, 14, 15, 16, and 17. One made a lunar swingby: Apollo 13 - a malfunction forced NASA to cancel the landing. In a statement, the China National Space Administration said a capsule with the moon rocks landed in Inner Mongolia at about 2 a.m. Two missions orbited the moon: Apollo 8 and 10. Three missions orbited the Earth: Apollo 7, 9 and Apollo-Soyuz. The Apollo program included 12 manned missions that launched in the late 1960s and early 70s. ![]()
