SternisheFan writes: The moon’s battered crust is riddled with deep fractures that may extend miles underground, according to the first findings from two NASA spacecraft orbiting Earth’s nearest neighbor. The results of the mission, led by a Massachusetts Institute of Technology scientist, surprised researchers, who said it will provide new insight into the evolution of the early solar system, and even help inform the search for life on Mars. Announced Wednesday, the discoveries are also a reminder that the familiar moon still holds secrets four decades after NASA ended its manned missions there. “We have known that the moon’s crust and other planetary crusts have been bombarded by impacts, but none of us could have predicted just how cracked the lunar crust is,” said Maria Zuber, the MIT geoscientist who led the mission, called GRAIL.
