At the Astrotech payload processing facility at Vandenberg Air Force Base in California, technicians configure the equipment for the fueling of the Glory spacecraft, seen in the background wrapped in a protective covering, with its attitude control propellant.

The Orbital Sciences Corp. Taurus XL rocket will carry NASA's Glory spacecraft into low Earth 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.
