Mission: Phoenix
Location: Launch Pad 17-A
Launch Vehicle: Delta II 7925
Launch Date: Aug. 3, 2007
Launch Time: 5:35:21 a.m. EDT

Phoenix was transported to Pad 17-A at Cape Canaveral Air Force Station for mating to the Delta II on Monday, July 23.

The flight program verification test was conducted successfully on Wednesday, July 25. This is an electrical test that confirms the Delta II and Phoenix are working together as an integrated system.

Technicians are installing the Delta II payload fairing around the Phoenix spacecraft Friday.

The Delta II second stage is scheduled to be loaded with its complement of storable propellants on July 31.

The mobile service tower, or gantry, is scheduled to be retracted from around the Delta II at 8:30 p.m. on Thursday, Aug. 2, for launch the next morning.

Mission: Dawn
Location: Astrotech payload processing facility
Launch Pad: 17-B
Launch Vehicle: Delta II 7925-H
Launch Timeframe: Sept. 7 – Oct. 15

A firm date for launch is still being determined based on the launch window for the science of the mission, the availability of the Eastern Range and the necessary tracking, data and telemetry support. The launch of Dawn is currently expected to occur no later than Sept. 26; however, a launch date as early as Sept. 7 is being preserved in planning schedules.

Dawn was removed from the launch vehicle on Sunday, July 22. The spacecraft was returned to the Astrotech payload processing facility near Kennedy Space Center at 7:30 a.m. that day. No processing activities are currently scheduled.
