The mated Pegasus and spacecraft will be transported by trailer back out to the hot pad, located next to the runway, just days before the launch. Final launch preparations and testing will be performed at the hot pad from a van parked next to the area. To reunite the L-1011 and the Pegasus, the entire L-1011 aircraft is lifted by hydraulic jacks and then gently lowered onto the Pegasus and secured.

The Pegasus was transported by trailer into the High Bay area in the Multi-Payload Processing Facility (MPPF) for integration after arriving at KSC.

LASP Activity –
December has been an intense month at LASP for the Mission Operations team as they fine-tune the activity plans for launch and the first 30 days following launch. After initial spacecraft checkout and verification, the instruments will be activated one at a time. The sequence considerations include general contamination, solar exposure, and the SOLSTICE high voltage usage and stellar calibration needs. The goal is to make the activation process as efficient as possible, with instrument safety a priority. A 2-day dry run test for instrument commissioning is scheduled for early January. The plan allows the instruments to begin collecting test data immediately after they are activated through windows in the instrument doors. After a brief out-gassing period to reduce self-contamination, the doors will be opened and true data will be collected for the next 5 years.

In mid January the Orbital personnel who have worked on the SORCE software, hardware, and mission development will visit Boulder for a final Mission Operations rehearsal. This rehearsal will focus on the first 36 hours of spacecraft operations after launch. Orbital personnel will participate in SORCE Mission Operation activities until after the launch when the spacecraft is stable, and when the instruments and the spacecraft are performing as expected.

The SORCE web page – – is changing weekly. The latest launch information is updated on-line. New items are being added including animations, photos, interviews, and interactive activities. After launch, the data collection and science will be prominent features of the site. If you have any comments or suggestions, please contact the SORCE web developer, Ann Windnagel (

For those who do not have access to the web for the latest launch information, a special SORCE phone line has been activated. By calling (303) 735-3132 you can hear a recorded message regarding the status of the SORCE launch and any breaking news.

In preparation for launch, several SORCE public relations pieces are completed. The SORCE brochure is available by e-mailing with your mailing address. LASP is preparing for the launch with new instrument photos for the lobby, and a large 10’ wide by 7.5’ tall SORCE display for outside the Mission Operations Center. The moveable display will feature the spacecraft, instruments, and a science overview of the SORCE mission and goals.

Greg Kopp, TIM instrument scientist, participated in the Colorado Science Convention in Denver in late November. In cooperation with the CU Science Discovery program, Greg presented a talk on the SORCE mission to K-12 science educators from Colorado and surrounding states. The goal was to educate teachers on the SORCE mission and
