Delta 2 launch of GPS satellite delayed [Note: Sent by PM to yours truly. Hey, I do pretend to have a day job <<VBG>>] Can't believe the infobot missed this one! From the Florida/Space Today website, updated 5/10/99: UPCOMING LAUNCH SCHEDULE No new date set: Air Force Delta 2 (7925) with the NAVSTAR Global Positioning System 2R-3 spacecraft from pad 17A at Cape Canaveral Air Station, Fla. Launch Time TBD. (Launch delayed from May 15 while damage inspections are made to the satellite after rain leaked into the pad). Tentatively first or second week of June: Boeing Delta 2 (7320) with NASA's Far Ultraviolet Spectroscopic Explorer (FUSE) spacecraft from pad 17A at Cape Canaveral Air Station, Fla., during a launch window of 11:36 a.m. to 12:48 p.m. EDT (1536-1648 GMT). (Launch will occur no sooner than 21 days after Delta/GPS clears pad 17A, possible date of June 11; pad 17B liftoff not possible since engineering study not performed of launching with 3 solid rocket motors given special pad exhaust system, so mission must go from pad 17A). June 24: Boeing Delta 2 (7420) on third Globalstar mission (4 comsats) from pad 17B at Cape Canaveral Air Station, Fla., during a launch window of 6:04 to 6:06 a.m. EDT (1004-1006 GMT). ----- Updated May 10, 1999 Delta 2 launch of GPS satellite delayed 45th Space Wing News Release CAPE CANAVERAL AIR STATION, Fla. - The U.S. Air Force Delta 2 launch that had been scheduled for as early as May 15 from here has been postponed to no earlier than May 23 due to rainwater intrusion into the Global Positioning System (GPS) satellite mated to the rocket. The moisture got into the satellite on Saturday, May 8 during a heavy thunderstorm at Cape Canaveral. The extent of the water damage to the satellite is unknown at this time. The Air Force plans to remove the satellite from the Delta 2 booster for evaluation. It's too soon to know if the moisture damaged the satellite. An assessment will be made once the spacecraft is moved back to the processing facility. At the time of the mishap, the satellite was perched on top of the Delta 2 rocket and was shrouded in a protective "clean room" which is part of the mobile service tower at Space Launch Complex 17A. Technicians were conducting routine tests of the satellite, but had to evacuate the pad due to lightning in the area Saturday afternoon. When given the clearance to return to the pad, technicians -- a mix of Air Force and contractor personnel -- discovered that rainwater had leaked into the clean room. Moisture was found on the satellite. The Air Force has convened an Operations Review Board to examine the circumstances of this mishap. More information will be provided as it becomes available.
