Expendable Launch Vehicle Status Report
Spacecraft: Wide-field Infrared Survey Explorer (WISE)
Launch Vehicle: Delta II 7320
Launch Pad: SLC-2, Vandenberg Air Force Base, Calif.
Launch Date: Dec. 7, 2009
Launch Window: 6:10 - 6:23 a.m. PST

Testing has been conducted successfully on the Tracking & Data Relay Satellite transmitter that will be used on the rocket. It will relay vehicle data to the ground during the launch and will be evaluated for possible use on future Delta II missions from Vandenberg. Second stage propellant system qualification testing has been completed. Three days of guidance and control system checks are currently under way. The Delta II flight simulation is currently scheduled for Nov. 11. The first stage will be loaded with liquid oxygen on Nov. 12 for leak checks and associated testing.

At the Astrotech payload processing facility on north Vandenberg, work continues to load and then freeze the cryogenic hydrogen. This activity is approximately 60 percent complete and will continue for about another week. This will be used to supercool the infrared telescope during its six months of observations. There then will be one final week of spacecraft testing before work begins to prepare WISE to move to the launch pad for integration with the Delta II.

Spacecraft: Solar Dynamics Observatory (SDO)
Launch Vehicle: Atlas V-401
Launch Pad: Launch Complex 41, Cape Canaveral Air Force Station, Fla.
Launch Date: Feb. 3, 2010
Launch Window: 10:53 - 11:53 a.m. EST

Prelaunch testing is nearing completion that leads to the milestone of fueling the spacecraft in early January. As an outcome of electrical testing, the SDO test team currently is doing analysis of the spacecraft grounding system.

The Atlas rocket first-stage booster arrived by air at Cape Canaveral Air Force Station on Oct. 26. The Centaur upper stage is now scheduled to arrive in the late afternoon or early evening on Nov 16 and be offloaded the following morning on Nov. 17.
