CAPE CANAVERAL, Fla. -- Lockheed Martin technicians in Astrotech Space Operation's payload processing facility in Titusville, Fla., prepare to test the solar arrays on NASA's Gravity Recovery and Interior Laboratory-A, or GRAIL-A, spacecraft to ensure that they will function as planned during the mission. The electrical power subsystem on each of GRAIL's twin spacecraft includes two solar arrays and a lithium ion battery. Each solar array is capable of producing no less than 700 watts.
