Spacecraft: Wide-field Infrared Survey Explorer (WISE)
Launch Vehicle: Delta II 7320
Launch Pad:  SLC-2, Vandenberg Air Force Base, Calif.
Launch Date:  no earlier than Dec. 9, 2009 
Launch Window: 6:10 - 6:23 a.m. PST 

The launch of WISE aboard the Delta II is being rescheduled by 
approximately two days. A launch date of Dec. 9 currently is under 
review. This additional time will allow sufficient time for a review 
of flight data from a Delta IV to be launched from Cape Canaveral Air 
Force Station planned early in the first week of December. 

The Delta II flight simulation was conducted successfully on Nov. 11. 
The first stage was loaded with liquid oxygen on Nov. 12 for leak 
checks and associated launch vehicle testing. There were no issues or 
concerns with the Delta II rocket. 

At the Astrotech payload processing facility on north Vandenberg, work 
is complete to load and then freeze the cryogenic hydrogen. This 
hydrogen will be used to supercool the infrared telescope during its 
six months of observations. There is one final week of spacecraft 
testing which is under way. Work will then begin to prepare WISE to 
move to the launch pad on or about Nov. 20 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 

At the Astotech Space Operations Center, deployment testing of the SDO 
high gain antennas and solar arrays is complete. On Nov. 18, they 
will be stowed for flight.

The Atlas rocket first-stage booster arrived by air at Cape Canaveral 
Air Force Station on Oct. 26. The Centaur upper stage is scheduled to 
arrive and be offloaded Wednesday morning.
