EXPERIENCE:
Walheim was commissioned as a second lieutenant in the Air Force in May 1984. In April of 1985 he was assigned to Cavalier Air Force Station in Cavalier, North Dakota, where he worked as a missile warning operations crew commander. In October 1986, he was reassigned to the Johnson Space Center, Houston, Texas, where he worked as a mechanical systems flight controller and was the lead operations engineer for the Space Shuttle landing gear, brakes, and emergency runway barrier. Walheim was transferred to Headquarters Air Force Space Command in Colorado Springs, Colorado, in August 1989 where he was manager of a program upgrading missile warning radars. He was selected for USAF Test Pilot School in 1991, and attended the course at Edwards AFB California in 1992. Following his graduation, he was assigned to the F-16 Combined Test Force at Edwards where he was a project manager, and then commander of the avionics and armament flight.

Walheim Spaceflight Log

  • 8 April 2002 Flight: STS-110. Flight Up: STS-110. Flight Back: STS-110. Flight Time: 10.82 days.

Walheim Chronology

8 April 2002 - STS-110. Assignment: Prime Crew. Flight: STS-110. Launch delayed from March 22, April 4. Space Shuttle Atlantis entered an orbit of approximately 59 x 229 km x 51.6 deg at 2052 UTC, and separated from the External Tank, ET-114. ET-114 reached apogee around 2122 UTC and reentered over the Pacific about 2150 UTC at the end of its first orbit. Atlantis fired its OMS engines at apogee to raise its perigee to 155 km. Further orbit changes will lead to a rendezvous with the Space Station on Station mission 8A. STS-110 carried the S0 truss segment to the Station. The truss was the first segment of the main backbone of the Station which was to grow to carry the large solar panel wings and radiators. Cargo manifest:

  • Bay 1-2: Orbiter Docking System - 1800 kg + 3 EMU spacesuits - 360 kg
  • Bay 4-13: S0 Truss - 12623 kg. The S0 truss, built by Boeing/Huntington Beach, was 13.4 m long and 4.6 m in diameter. The main truss had a hexagonal cross section. One face carried fluid, power and data cables, while another face carried the rails for the Mobile Transporter. The S0 contained avionics, GPS antennae, and a radiation dose monitor. The S0 would be attached to the LCA (Lab Cradle Assembly) which was attached to the top of the Destiny lab module in 2001. Attached to S0 were:
    • 4 x MTS (Module to Truss Structure) struts. These were used to connect it to the Destiny module
    • Airlock Spur. This was a 4.2 m beam that hinged out to connect to the Quest module and had handrails for spacewalkers
    • Mobile Transporter (MT). This was made by TRW Astro Aerospace in Carpinteria and was an 885 kg, 2.7 m long truck which moved on the S0 rails to transfer heavy cargo along the truss.
  • Sill: RMS arm - 410 kg
  • Total: 15193 kg
