Q&A with Steve Skladanek, president of Lockheed Martin Commercial Launch Services

The U.S. Air Force’s ninth Global Positioning System (GPS) 2F satellite, GPS 2F-9, is encapsulated in the Delta 4 rocket’s four-meter-diameter nose cone at a processing facility and then moved to the launch pad at Complex 37 for mating to its booster inside the mobile service tower.

The step-by-step stacking of United Launch Alliance’s final Delta 2 rocket was completed in June at Vandenberg Air Force Base in California for liftoff Sept. 15 with an Earth science satellite for NASA.

The next launch of United Launch Alliance’s Atlas 5 rocket with the U.S. Air Force’s fifth Advanced Extremely High Frequency communications satellite, previously scheduled for Thursday, has been delayed to no earlier than July 12 to replace a failed battery on the vehicle.
