Apollo Moon Photos of China


Launched as GRAIL A and GRAIL B in September 2011, the probes were renamed Ebb and Flow by schoolchildren in Montana. The probes operated in almost circular orbit near the lunar poles at an altitude of approximately 34 miles, until their mission came to an end in December 2012. The distance between the twin probes altered a bit as they soared over areas of lesser and greater gravity that were caused by visible topological features on the Moon's surface, such as impact craters and mountains--as well as by masses that were secreted beneath the lunar surface. Similarly, in Norse mythology, Mani is the male personification of the Moon. Mani wanders across the sky in a horse and carriage, perpetually pursued by the Great Wolf Hati who catches him at Ragnarok--which is the "Twilight of the Gods," and the end of everything, in Norse mythology--that is, until it all begins anew. "For the smaller craters, it's like if you're filling a bucket, eventually your bucket gets full, but if you keep pouring cups of water into the bucket, you can't tell how many cups of water beyond full you've gone. Looking at the larger craters at the subsurface might give us insight, because that 'bucket' isn't full yet," Dr. Soderblom added.
