In Bldg. 1610 at Vandenberg Air Force Base in California, workers place another lower segment of a transportation canister around the NOAA-N Prime spacecraft. NOAA-N Prime is the latest polar-orbiting operational environmental weather satellite developed by NASA for the National Oceanic and Atmospheric Administration. The satellite is scheduled to launch Feb. 4 aboard a Delta II rocket from Vandenberg Air Force Base. Photo credit: NASA/ Daniel Liberotti, VAFB
