April 25, 2008 George H. Diller Kennedy Space Center, Fla. 321-867-2468 george.h.diller@nasa.gov STATUS REPORT: ELV-042508 EXPENDABLE LAUNCH VEHICLE STATUS REPORT Mission: GLAST (Gamma-ray Large Area Space Telescope) Location: Astrotech payload processing facility Launch Vehicle: Delta II 7920-H Launch Pad: 17-B Launch Date: TBD (under assessment) Launch Window: 11:45 a.m. - 1:40 p.m. EDT At Pad 17-B on Cape Canaveral Air Force Station, the Delta II second stage was hoisted into position on Tuesday. Upcoming milestones include a cryogenic test of the first stage using liquid oxygen, along with an associated countdown operation. A Simulated Flight Test follows that, encompassing the flight events that occur from liftoff through spacecraft separation to exercise the onboard vehicle systems of the Delta II. Both tests will occur approximately the second week of May. Meanwhile, at the Astrotech payload processing facility, end-to-end communications testing through the Tracking and Data Relay Satellite System has been completed. Three sunshades associated with the star tracker system were installed on Wednesday, and the sun trackers associated with the solar arrays were cleaned. The closeouts of the spacecraft thermal blankets continue. A final cleaning of the overall spacecraft and black light inspection are under way today, which are the last activities for spacecraft processing until the fueling of the spacecraft. Fueling will be scheduled once a launch date has been determined.
