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

LDEF (Prelaunch), AO038 : Interstellar Gas Experiment, Tray E12



LDEF (Prelaunch), AO038 : Interstellar Gas Experiment, Tray E12 The prelaunch photograph provides a view of the Interstellar Gas Experiment (IGE) hardware and shows the orientation of two (2) experiment canister housings mounted in a twelve (12) inch deep peripheral tray. The experiment utilizes seven (7) canisters containing high-purity beryllium copper collecting foils, three (3) located in peripheral trays and four (4) located in trays on the space end of the LDEF, to meet experiment objectives. The active portion of the experiment consist of canister electronic timing devices and pyrotechnic cutters that control the exposure time of each collector foil. An electronic voltage multiplier system provides a bias voltage to the grid network located above the beryllium copper collecting foils.The batteries and the electronics are housed beneath the experiment baseplate facing the LDEF interior. The white painted surface area within the LDEF tray provides the optical properties required to maintain the experiment components within temperature limits. The two (2) rectangular openings in opposite corners of the experiment baseplate provide the mountings for the ground support equipment test connectors. A white grid voltage connector box, mounted on the side of each canister housing, provides the termination point for the cables running from the grid voltage box beneath the baseplate. The canister housing is a welded aluminum structure with aluminum mounting flanges. The experiment components are assembled using non-magnetic stainless steel fasteners. The aluminum housing cover, removed prior to flight, protects experiment components from damage and large particle contamination during ground handling.
