Boeing has delayed the launch of a Delta III rocket to assess any potential implications from the U.S. Air Force launch of a Titan IV rocket last Friday.
The Delta III had been scheduled to make a launch attempt from Cape
Canaveral Air Station, Fla., on Sunday, but Boeing officials delayed the launch until at least Tuesday, May 4. The launch window for the Orion 3 satellite built by Hughes Space and Communications opens at 8:56 p.m. and closes at 10:04 p.m. EDT.
Loral Space & Communications will own and operate the satellite, which will expand the Loral satellite service fleet by providing telecommunications for the entire Asia-Pacific region.
Boeing Aims For May 4
Cape Canaveral April 27, 1999 – Pending range availability, Boeing will attempt to launch a Delta III rocket carrying the Orion 3 satellite Tuesday, May 4.
If another launch, planned for Friday, April 30, goes as scheduled, the Delta team could launch as early as Sunday, May 2. The last Delta III launch attempt ended in an on-pad abort, when ground-support software did not send the main-engine ignition command to the
vehicle.
The situation occurred when a computerized vehicle-systems check, run every tenth of a second, interrupted the ignition command due to a software error. The main engine ignition command was never issued and the launch was automatically aborted.
The launch team replicated the problem and is testing the revised software. The launch windows for May 2 – 4 are 8:57 to 10:05, 8:56 to 10:05 and 8:56 to 10:04 p.m. EDT respectively.
The Orion 3 satellite, built by Hughes Space and Communications, will be owned and operated by Loral Space & Communications. The spacecraft will expand the C-band and Ku-band coverage area of Loral's satellite service fleet to include the entire Asia-Pacific region including Korea, China, Japan, Australia, India, Southeast Asia, Oceania and Hawaii.
