The moon marks 40 years without a human visitor, prepares for impending probe crashes
It's likely not an anniversary anyone thought we would meet after the first moon landing, but today marks 40 years since Gene Cernan left the last footprint on the moon as Apollo 17 ended its mission. That was the last of six manned missions to the lunar surface (nine including those that didn't land), which saw twelve men actually walk on the moon in all. The years since have of course seen continued exploration of the moon through other means, though, and next week will see another major event when NASA's twin GRAIL spacecraft conduct a planned crash into a mountain near the lunar north pole. Those have been in orbit since January 1st, creating a high-resolution map of the moon's gravitational field and collecting data that promises to provide more detail than ever about its internal structure and composition. You'll be able to follow along on NASA's website as that happens beginning at 5PM Eastern on Monday, December 17th. [Image credit: NASA / Eugene Cernan]
NASA's GRAIL spacecraft begin the process of staring way too hard at the moon
NASA's overall initiatives may be throttled, but the Gravity Recovery And Interior Laboratory (GRAIL) spacecraft haven't heard of any such limitations. These guys have officially started their collection mission, orbiting the moon for the next 80-some-odd days in order to obtain a high-resolution map of the lunar gravitational field. Why? Humans told 'em too, of course. Outside of the conventional knee-jerk response, scientists are also hoping to grok more about the moon's "internal structure and composition," and perhaps even get a better understanding of how "Earth and other rocky planets in the solar system formed and evolved." Cleverly, the GRAIL mission's twin machines are named Ebb and Flow (thanks to a group of youngsters in Bozeman, Montana), and while it's not being made public, we wouldn't be shocked to hear that the whole thing is being covertly funded by Sir Richard Branson. The moon is totally the next hot real estate market, right?
NASA films dark side of the moon, finds no evidence of Brain Damage (video)
Take a moment to Breathe, because this one's kind of heady. NASA has just published a new video of the Dark Side of the Moon and, contrary to popular belief, it's not really all that dark. (We'd probably describe it as a subdued gray, if we had to, but feel free to go with Any Colour You Like.) Compiled into a 30-second video clip, this footage provides a cursory glimpse of the moon's hind parts (its "B-Side," if you will), panning over the rock from north to south, in all its crater-y glory. It's all part of an initiative from NASA's Gravity Recovery And Interior Laboratory (GRAIL), which presumably spent a lot of Time and Money to build its twin spacecraft, nicknamed Ebb and Flow. On January 19th, the lab sent the pair up to that Great Gig in the Sky, as part of the GRAIL MoonKAM mission -- a "progressive" educational outreach program geared toward middle school students. Ebb was charged with filmic duties, and did a remarkable job of shooting On the Run with its MoonKAM camera, returning high res footage to NASA's engineers, and giving both Us and Them something to think about during the next lunar Eclipse. See the video (along with its eerily sync-able counterpart) after the break, and if you've got any questions about it, please don't hesitate to Speak to Me.
