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

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 blocks around the periphery of the experiment tray show the results of contamination and exposure to the space environment. The variation in color, from off-white along the top flange to brown at other locations, is attributed to variations in the atomic oxygen flux intensity. A surfaces exposed to a higher intensity of atomic oxygen flux will have less contamination due to the scrubbing or cleaning action that occurs when the atomic oxygen molecules impact that surface. The pink and the greenish-gray tints on the two (2) debris panels are 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 bottom of the panels is caused by light reflecting from the tray sidewalls.
