the-star-stuff: Lunar scientists shed light on Moon’s impact history Analysis shows that craters formed near the Nectaris impact basin were created by projectiles hitting twice as fast as those found on more ancient terrains. By NASA’s Ames Research Center in Moffett Field, California — Published: February 28, 2012 A team of researchers from the NASA Lunar Science Institute (NLSI) at NASA’s Ames Research Center in Moffett Field, California, has discovered that debris that caused a “lunar cataclysm” on the Moon 4 billion years ago struck it at much higher speeds than those that made the most ancient craters. The scientists found evidence supporting this scenario by examining the history of crater formation on the Moon. [Continue Reading…]
