Expendable Launch Vehicle Status Report
Mission: Ice, Cloud and Land Elevation Satellite / Cosmic Hot Interstellar Spectrometer
Launch Vehicle: Boeing Delta II with Reduced Height Dual Payload Attach Fitting (RH DPAF)
Launch Pad: SLC-2W, Vandenberg Air Force Base (VAFB)
Launch Date: December 19, 2002
Launch Window: 4:45 - 5:30 p.m. PST

The two-day operation to install the two halves of the payload fairing around the payload atop the rocket begins today and is the final major activity to be performed before launch. The Flight Program Verification, the last major test, was completed on Dec. 5 and verified that the vehicle and the spacecraft are operating in an integrated manner. The ICESat/CHIPSat payload was mated to the Delta II at the launch pad on Dec. 3 and a state of health check of the two satellites was successfully performed.

The Flight Readiness Review is scheduled for Dec. 13. At this time there are no issues or concerns with the Boeing Delta II vehicle or the spacecraft.

On launch day, the gantry-like mobile service tower will be retracted from around the spacecraft at 6:30 a.m. PST. Cryogenic fueling of the rocket will begin at 3 p.m. PST. Launch is on schedule for Thursday, Dec. 19 at 4:45 p.m. PST.

Launch coverage on NASA Television begins at 3 p.m. PST.

Mission: Solar Radiation and Climate Experiment
Launch Vehicle: Pegasus XL
Launch Location: Cape Canaveral Air Force Station
Launch Date: January 25, 2003
Launch Time: 3:10 p.m. - 4:08 p.m. EST T-0: 3:14 p.m. EST

At Vandenberg Air Force Base, the mating of the launch vehicle to the L-1011 aircraft and the Combined Systems Test (CST) is scheduled to occur on Friday, Dec. 13. The ferry to Cape Canaveral using the Orbital Sciences L-1011 aircraft is scheduled for Dec. 17. Once at KSC in the Multi-purpose Payload Processing Facility (MPPF), three Flight Simulations are planned prior to launch. One involves the Pegasus launch vehicle on Dec. 22, the remaining two flight simulations on Jan. 3 and Jan. 8 involve both the Pegasus and the SORCE spacecraft.

Mating of the spacecraft to the Pegasus is currently scheduled for Jan. 6 and fairing installation activities begin on Jan. 14. On Jan. 22, the integrated vehicle will be transported to the runway at Cape Canaveral Air Force Station and mated to the L-1011 aircraft. Also on that day, Combined Systems Test #2 is scheduled. This includes the SORCE spacecraft, the Pegasus launch vehicle and the L-1011.

Meanwhile, at KSC in the MPPF, work is being performed on SORCE in anticipation of the arrival of the Pegasus. The end-to-end communications test with the Hartebeesthoek tracking station in the Republic of South Africa is scheduled for this week.

The SORCE project is managed by NASA's Goddard Space Flight Center, the spacecraft is built by the Orbital Sciences Space Systems Group, and the instruments are built by the Laboratory for Atmospheric and Space Physics (LASP).
