Expendable Launch Vehicle Status Report
Mission: High Energy Solar Spectroscopic Imager
Launch Vehicle: Orbital Sciences Pegasus XL
Launch Location: Cape Canaveral Air Force Station
Launch Date: Feb. 5, 2002
Launch Window: 3:21 - 5:21 p.m. EST (T-0: 3:26 p.m.)

On January 28 at a follow-up Flight Readiness Review, NASA and Orbital Sciences cleared the Pegasus XL launch vehicle for flight. Approximately twenty days of data analysis and reviews were conducted of hardware commonality between the Pegasus XL booster and the National Missile Defense BV-3 booster that failed during launch at Vandenberg Air Force Base (VAFB) in December. The launch of Pegasus/HESSI is now firmly scheduled for Feb. 5 at 3:26 p.m.

At VAFB, mating of the Pegasus to the L-1011 occurred yesterday, Jan. 29, and the ferry flight to KSC will occur on Feb. 1. The touchdown at the Skid Strip on Cape Canaveral Air Force Station is anticipated to occur in the late afternoon. A launch countdown dress rehearsal with the launch team will then be held on Saturday, Feb. 2. A Combined Systems Test (CST), an integrated test for the L-1011 and the Pegasus, will be held on Sunday, Feb. 3.

The Orbital Sciences L-1011 aircraft carrying the 3-stage Pegasus booster is scheduled to depart for launch at 2:28 p.m. on Tuesday, Feb. 5.

Mission: Tracking and Data Relay Satellite-I
Launch Vehicle: Lockheed Martin Atlas IIA (AC-143)
Launch Pad: Launch Complex 36-A, Cape Canaveral Air Force Station
Launch Date: March 8, 2002
Launch Window: 5:39 - 6:19 p.m. EST

The TDRS-I spacecraft is anticipated to arrive aboard a C-17 air cargo plane at the Shuttle Landing Facility on Saturday morning. The satellite is being shipped from the Boeing Satellite Systems plant in El Segundo, Calif. It will be taken to the SAEF-2 spacecraft processing facility at KSC for three weeks of final checkout, fueling and encapsulation into the Atlas payload fairing.

At Pad A on Space Launch Complex 36, no significant Atlas vehicle processing activity is scheduled this week and the vehicle is awaiting the arrival of the spacecraft on or about Feb. 25.

Mission: Earth Observing System Aqua Observatory
Launch Vehicle: Delta II 7920-10L
Launch Pad: Space Launch Complex 2, Vandenberg Air Force Base
Launch Date: No earlier than April 2002

Aqua spacecraft testing is continuing at the TRW plant in Redondo Beach, Calif. The spacecraft is currently planned to be shipped to Vandenberg Air Force Base on Feb. 22.

The erection of the Boeing Delta II launch vehicle on the pad at Space Launch Complex 2 is planned to begin on or about Feb. 21. The Boeing review to assess readiness of the vehicle and the launch pad for that activity is scheduled for Feb. 19 in Huntington Beach, Calif.
