Atlas V & Delta IV Get New Launch Dates

The stalled launch of an Atlas V rocket is being rescheduled for early next Monday and a Delta IV rocket also has a new launch date: Dec. 2.

The 19-story Atlas and its payload -- an Intelsat commercial communications satellite -- now is slated to blast off from Launch Complex 41 at Cape Canaveral Air Force Station at 12:50 a.m. Monday. The launch window will extend until 2:20 a.m.

The launch had been slated for last Saturday, but a signal relayer failed to operate properly during launch countdown. The Atlas V was rolled back to its assembly building, and the faulty Ordnance Remote Control Assembly was replaced. The assemblies are used to route commands to small explosives used to separate the rocket's stages and deploy its satellite cargo.

A launch readiness review is scheduled for Friday and the United Launch Alliance rocket is to be returned to the launch pad on Saturday.

The Delta IV rocket and its payload -- a military communications satellite -- now are scheduled to blast off from Launch Complex 37 at 7:21 p.m. Dec. 2. The launch window that day will extend until 8:41 p.m. The mission had been set for Nov. 19 but the satellite payload had to be returned to a processing facility in south Titusville so critical batteries could be recharged.
