The GRAIL spacecraft will be launched side-by-side on a single Delta II vehicle during a 26-day launch period that opens on September 8, 2011. By very precisely measuring the distance of one orbiter relative to the other, the orbital perturbations caused by the Moon could be observed. Even though NASA's twin Grail probes are history, the mission is far from finished. The first images and video from NASA ’s GRAIL mission of the far side of the moon were captured on January 19, 2012 by the MoonKAM onboard the lunar spacecraft Ebb as part of a test.
