Ok, we'll keep this thread going for attempt 2 tomorrow. I'll reset it as the live thread for the Saturday night attempt during the day.

Delta IV GPS IIF SV-1 Mission Tentatively Rescheduled for May 22

Cape Canaveral AFS, Fla. (May 21, 2010) - The launch attempt of the United Launch Alliance Delta IV with the Air Force’s Global Positioning System IIF SV-1 satellite (GPS IIF SV-1) was scrubbed tonight and has been tentatively rescheduled for May 22. During the final minutes of the launch countdown, the telemetry signal between the Global Positioning System satellite and the satellite ground support equipment was lost. This issue could not be resolved in time to launch during tonight’s 18 minute launch window.

The Delta IV rocket and GPS IIF SV-1 satellite are safe and secure at this time. The launch is tentatively rescheduled for Saturday, May 22, with a launch window of 11:21 – 11:39 p.m. EDT.

Delayed again, to Sunday:

Delta IV GPS IIF SV-1 Mission Rescheduled for May 23

Cape Canaveral AFS, Fla. (May 22, 2010) - The launch attempt of the United Launch Alliance Delta IV with the Air Force’s Global Positioning System IIF SV-1 satellite (GPS IIF SV-1) is rescheduled for Sunday, May 23. Mission managers expect the telemetry signal issue between the Global Positioning System satellite and the satellite ground support equipment that caused the scrub of Friday’s launch attempt to be resolved in time for a launch attempt Sunday.

The Delta IV rocket and GPS IIF SV-1 satellite are safe and secure at this time. Sunday’s launch window is 11:17-11:35 p.m. EDT. The weather forecast calls for a 70 percent chance of acceptable weather during the launch window.

So... a problem in telemetry betwen the satellite and the ground. If the problem is a hardware issue on the satellite itself, how serious might that be in terms of delays? How long would it take to get the spacecraft off the LV, back to the clean room and removed from the PLF?

More often than not these problems end up being on the "ground" side. A spacecraft problem would probably cause a much longer delay.
