A technician works in the Astrotech payload processing facility at Vandenberg Air Force Base in California before the pieces that will make up the payload fairing for the Glory mission are moved to the East High Bay. The payload fairing will protect the Glory spacecraft from aerodynamic pressures and heating during the first part of its climb into orbit. 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
