At Astrotech Space Operations in Titusville, Fla., technicians are testing the range of motion on the high-gain antenna for the Lunar Reconnaissance Orbiter. The orbiter will carry seven instruments to provide scientists with detailed maps of the lunar surface and enhance our understanding of the moon's topography, lighting conditions, mineralogical composition and natural resources. Information gleaned from LRO will be used to select safe landing sites, determine locations for future lunar outposts and help mitigate radiation dangers to astronauts. Launch of LRO is targeted no earlier than June 2. Photo credit: NASA/Jim Grossmann
