CAPE CANAVERAL, Fla. – Technicians inspect the solar arrays for NASA's Lunar Reconnaissance Orbiter, or LRO, at the Astrotech processing facility in Titusville, Fla. The spacecraft was built by engineers at Goddard Space Flight Center, where it recently completed two months of tests in a thermal vacuum chamber. 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. The polar regions of the moon are the main focus of the mission because continuous access to sunlight may be possible and water ice may exist in permanently shadowed areas of the poles. Accompanying LRO on its journey to the moon will be the Lunar Crater Observation and Sensing Satellite, or LCROSS, a mission that will impact the lunar surface in its search for water ice. Launch of LRO/LCROSS is targeted for April 24. Photo credit: NASA/Jack Pfaller KSC-2009-1641

Summary
The postflight photograph was taken in the SAEF II at KSC prior to experiment removal from the LDEF. The originally white paint dot on clamp block at the center of the left tray flange and at the center of the bottom tray flange is dark brown. Since this tray is located on LDEF's trailing edge, no contamination has been cleaned away by atomic oxygen impacts. The pink and the greenish-gray tints on the two (2) debris panels are a by-product of the chromic anodize coating process and not attributed to contamination and/or exposure to the space environment. The light band along the sides and across the bottom of the panels is caused by light reflecting from the tray sidewalls.
