[Satellite TODAY 11-22-10] United Launch Alliance (ULA) is set to launch a classified U.S. National Reconnaissance Office satellite on a Delta 4 Heavy rocket this evening from Cape Canaveral Air Force Station, ULA announced Nov. 19.
    The mobile service tower at Launch Complex 37 rolled back this morning, revealing the 23-story United Launch Alliance vehicle. The launch, the fourth by a Delta 4 Heavy, was delayed for a day due to a faulty ordnance line.
    The weather forecast remains 90 percent favorable today and throughout the weekend, should more attempts be needed, ULA said.
