VANDENBERG AIR FORCE BASE, Calif. -- At Space Launch Complex 576-E at Vandenberg Air Force Base in California, workers prepare NASA's Glory spacecraft, encapsulated in its protective fairing, to be lifted off of a transport. It will then be joined with the Taurus XL rocket's third stage, already delivered to a temporary processing tent near the pad. The Orbital Sciences Corp. Taurus XL rocket will carry Glory 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.
