MIT-Led Mission Reveals the Moon's Battered Crust Is Riddled With Cracks 39

SternisheFan sends this quote from the Boston Globe: "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." Here are the abstracts from the three studies published in Science.

Roaming Robot May Explore Mysterious Moon Caverns 29

ananyo writes "William 'Red' Whittaker often spends his Sundays lowering a robot into a recently blown up coal mine pit near his cattle ranch in Pennsylvania. By 2015, he hopes that his robot, or something like it, will be rappelling down a much deeper hole, on the Moon. The hole was discovered three years ago when Japanese researchers published images from the satellite SELENE1, but spacecraft orbiting the Moon have been unable to see into its shadowy recesses. A robot might be able to 'go where the Sun doesn't shine', and send back the first-ever look beneath the Moon's skin, Whittaker told attendees at a meeting of the NASA Innovative Advanced Concepts (NIAC) program in Hampton, Virginia, last week. And Whittaker is worth taking seriously-his robots have descended into an Alaskan volcano and helped to clean up the Three Mile Island nuclear power plant."

SETI To Scour the Moon For Alien Footprints? 167

astroengine writes "Although we have an entire universe to seek out the proverbial alien needle in a haystack, perhaps looking in our own backyard would be a good place to start. That's the conclusions reached by Paul Davies and Robert Wagner of Arizona State University, anyway. The pair have published a paper in the journal Acta Astronautica detailing how SETI could carry out a low-cost crowdsourcing program (a la SETI@Home) to scour the lunar surface for alien artifacts, thereby gaining clues on whether intelligent aliens are out there and whether they've paid the solar system a visit in the moon's recent history."
