NASA's GRAIL spacecrafts enter Moon's orbit, set to map its gravitational field in March
Way back in September, NASA's Jet Propulsion Laboratory sent a duo of Lockheed Martin-produced spacecraft toward one of its favorite test subjects, the Moon, as a part of its GRAIL mission -- Gravity Recovery And Interior Laboratory. Now, nearly four months later, the administration has announced that the GRAIL-A and -B twin crafts have planted themselves within our Moon's orbit. According to NASA, they're currently in "a near-polar, elliptical orbit with an orbital period of approximately 11.5 hours," and it plans to execute more "burn maneuvers" in the coming weeks to shorten that time frame to less than two. By March, the research crafts will be positioned in a "near-polar, near-circular orbit" 34 miles above its surface, at which point they'll begin surveying its gravitational pull, by using radio signals to determine the distance between both units. With this information, NASA hopes to better understand how gravity works, both above and below the Moon's surface, by detailing the findings in a high-resolution map. NASA also says that scientists can utilize it to get further insight into how our planets formed. Notably, both spacecraft feature a MoonKAM (Moon Knowledge Acquired by Middle school students), that will allow students request pictures of specific areas the lunar surface for later study. Best of all, using NASA's "Eyes on the Solar System" web app, you'll be able to follow the paths of both spaceships in detail. You'll find full details about the GRAIL mission at the source links below.
NASA's Curiosity Mars Rover stars in its very own photoshoot
NASA's already given us a glimpse at its Mars rover, courtesy of a USTREAM broadcast a few months back, but the crew over at BoingBoing has taken one small step for mankind by going even further in-depth with Curiosity before it launches in November. One lucky photographer was granted permission into the Jet Propulsion Laboratory in Pasadena, and the fruits of his bunny-suited labor showcase the nooks and crannies of NASA's latest and greatest. We're still kind of bummed that the rover won't be equipped with a zoom 3D camera as originally planned, but we've got a hunch James Cameron's taking it even harder. Be sure to hit the source link for a whole smattering of more angles, if intergalactic spacecrafts are your thing.
