Transporting GRAIL
Date: 20 May 2011
CAPE CANAVERAL, Fla. -- NASA's Gravity Recovery and Interior Laboratory, or GRAIL, spacecraft is loaded onto a tractor-trailer for transport to the Astrotech payload processing facility in Titusville, Fla. to be processed for launch. An Air Force C-17 cargo plane flew the spacecraft from the Lockheed Martin plant in Denver, Colo. to the Shuttle Landing Facility at Kennedy Space Center in Florida. The United Launch Alliance Delta II rocket that will carry GRAIL into lunar orbit already is fully stacked at NASA's Space Launch Complex 17B.

The GRAIL mission is a part of NASA's Discovery Program. GRAIL will fly twin spacecraft in tandem orbits around the Moon for several months to measure its gravity field. The mission also will answer longstanding questions about Earth's Moon and provide scientists a better understanding of how Earth and other rocky planets in the solar system formed.
