(04/19/1999) --- At Launch Pad 36A, Cape Canaveral Air Station, a Centaur upper stage is moved into place above the lower stage Lockheed Martin Atlas IIA rocket. The Lockheed Martin-manufactured Centaur IIA is powered by two Pratt & Whitney turbopump-fed engines, producing a total thrust of 41,600 pounds. The rocket is scheduled to launch the NASA GOES-L satellite on May 15, at the opening of a launch window which extends from 2:23 to 4:41 a.m. EDT. Once in orbit, the satellite will become GOES-11, joining GOES-8, GOES-9 and GOES-10 in space. The fourth of a new advanced series of geostationary weather satellites for the National Oceanic and Atmospheric Administration (NOAA), GOES-L is a three-axis inertially stabilized spacecraft that will provide pictures and perform atmospheric sounding at the same time. Once launched, the satellite will undergo checkout and then provide backup capabilities for the existing, aging operational satellites
