CAPE CANAVERAL, Fla. -- In Building 1555 at Vandenberg Air Force Base in California, ssembly is underway for the Taurus XL rocket that will launch NASA's Orbiting Carbon Observatory, or OCO, spacecraft. Lined up left to right are the Stage 1 and Stage 2 motors, the boattail, the avionics shelf and the Stage 3 motor. The graphite/epoxy boattail structure provides the transition from the smaller diameter of the Stage 2 motor to the larger diameter of the avionics skirt. The avionics skirt, also a graphite/epoxy structure, supports the avionics shelf and carries the primary structural loads from the fairing and payload cone. The aluminum avionics shelf supports the third stage avionics. The OCO is a new Earth-orbiting mission sponsored by NASA's Earth System Science Pathfinder Program. The launch of OCO is targeted for January. Photo credit: NASA/Randy Beaudoin, VAFB KSC-08pd3866

VANDENBERG AIR FORCE BASE, Calif. -- The Stage 1, 2 and 3 motors of the Taurus XL rocket are being prepared for transfer to Space Launch Complex 576-E at Vandenberg Air Force Base in California. The Taurus is the launch vehicle for NASA's Orbiting Carbon Observatory, or OCO, which is a new Earth-orbiting mission sponsored by NASA's Earth System Science Pathfinder Program. The observatory is scheduled to launch Feb. 23 from Vandenberg. The spacecraft will collect precise global measurements of carbon dioxide (CO2) in the Earth's atmosphere. Scientists will analyze OCO data to improve our understanding of the natural processes and human activities that regulate the abundance and distribution of this important greenhouse gas. This improved understanding will enable more reliable forecasts of future changes in the abundance and distribution of CO2 in the atmosphere and the effect that these changes may have on the Earth's climate.

VANDENBERG AIR FORCE BASE, Calif. -- On Launch Complex 576-E at Vandenberg Air Force Base in California, NASA's Orbiting Carbon Observatory, or OCO, atop Orbital Sciences' Taurus XL rocket has been erected for launch. Around the spacecraft's fairing, at top, is the non-flight environmental shield that will be removed before launch. OCO is scheduled for launch the Taurus rocket Feb. 24 from Vandenberg. The spacecraft will collect precise global measurements of carbon dioxide (CO2) in the Earth's atmosphere. Scientists will analyze OCO data to improve our understanding of the natural processes and human activities that regulate the abundance and distribution of this important greenhouse gas.

VANDENBERG AIR FORCE BASE, Calif. – In Orbital Sciences Corp. Building 1555 at Vandenberg Air Force Base in California, Orbital Sciences technicians continue to work on cabling on the aft end of the Taurus XL rocket's first stage motor. To the left is the interstage associated with the first stage. The Orbital Sciences Taurus XL rocket, targeted to lift off Feb. 23, 2011, from Vandenberg's Space Launch Complex 576-E, will take NASA's Glory satellite into low Earth orbit. Once in orbit, Glory will collect data on the properties of aerosols and black carbon. It also will help scientists understand how the sun's irradiance affects Earth's climate.

VANDENBERG AIR FORCE BASE, Calif. -- Inside the Astrotech processing facility at Vandenberg Air Force Base in California, technicians remove the shipping container surrounding NASA's Glory spacecraft. Next, technicians will take off Glory's protective covering before it is encapsulated in a protective payload fairing for flight. In early February, Glory is scheduled to be transported Space Launch Complex 576-E where it will be joined with the Taurus XL rocket, which is manufactured by Orbital Sciences Corp. Once Glory reaches orbit, it will collect data on the properties of aerosols and black carbon. It also will help scientists understand how the sun's irradiance affects Earth's climate. Launch is scheduled for 5:09 a.m. EST Feb. 23. For information, visit www.nasa.gov/glory. Photo credit: NASA/Ed Henry, VAFB KSC-2011-1115
