Dr. Weber has logged over 2,500 skydives since 1983. She received a silver medal in the U.S. National Skydiving Championships, 20-way freefall formation event, in both 1995 and 1991, and was in the world's largest freefall formation, a 297-way, in 1996. She is also an instrument-rated pilot.
Dr. Weber flew aboard the Space Shuttle Discovery on STS-70, which launched from the Kennedy Space Center on July 13, 1995, and returned there July 22, 1995. The five-member crew deployed the sixth NASA Tracking and Data Relay Satellite, and performed a myriad of scientific experiments. Dr. Weber's primary roles were in check out and deploy of the satellite, operation of biotechnology experiments, and as contingency spacewalk crew member, flight crew, and medical officer. During this nine-day mission, Discovery completed 142 orbits of the Earth and traveled 3.7 million miles.
Deployed TDRS 7. Payloads: Tracking and Data Relay Satellite (TDRS) G/ Inertial Upper Stage (IUS); Bioreactor Demon-stration System (BDS) B; Biological Research in Canisters (BRIC); Commercial Protein Crystal Growth (CPCG); Hand-Held, Earth-Oriented, Real-Time, Cooperative, User-Friendly, Location-Targeting and Environmental System (HER-CULES); Microcapsules in Space (MIS) B; Physiological and Anatomical Rodent Experiment (PARE)/National Institutes of Health (NIH) Rodents (R); Radiation Monitoring Experiment (RME) III; Shuttle Amateur Radio Experiment (SAREX) II; Space Tissue Loss (STL)/National Institutes of Health (NIH) Cells (C); Military Applications of Ship Tracks (MAST); Visual Function Tester (VFT) 4; Window Experiment (WINDEX).
Objective of mission STS-101 was repair, resupply and construction tasks aboard the international space station. This was the first launch with new electronic cockpit displays and other upgrades. The solid boosters separated at 10:13 GMT and the main engines cutoff at 10:19 GMT. The external tank, ET-102 then separated, with both orbiter and ET-102 in a 52 x 320 km initial orbit. At 10:54 GMT the OMS engines fired to raise perigee to 159 x 329 km x at 51.6 deg. Atlantis docked with the International Space Station's PMA-2 docking adapter on the Unity node at 04:31 GMT on May 21. At that time the ISS was in a 332 x 341 km orbit.
On May 22 mission specialists Jeff Williams and James carried out external maintenance work on the ISS.
On May 23 at 00:03 GMT the Atlantis crew opened the first hatch to PMA-2 and entered the Station. The crew replaced a set of batteries in Zarya, installed fans and ducting to improve airflow, and delivered supplies and equipment. Three hour-long orbit raising burns on May 24 and 25 by the RCS engines on Atlantis raised the station to a 372 x 380 km x 51.6 deg orbit.
The STS-101 crew left the station on May 26, closing the PMA-2 hatch at 08:08 GMT and undocking at 23:03 GMT. Atlantis performed a 180 degree flyaround of the station and departed the vicinity around 23:44 GMT.
Atlantis closed its payload bay doors around 02:30 GMT on May 29 and fired the OMS engines for deorbit at 05:12 GMT. The vehicle landed on RW15 at Kennedy Space Center at 06:20 GMT. Atlantis was to be turned around for the next ISS shuttle flight, STS-106.
Left in orbit was the renovated International Space Station, equipped with an upgraded electrical system, new fans, filters, fire extinguishers, smoke detectors and communications gear.
