Selected by NASA in January 1990, Walz is a veteran of three space flights, and has logged over 833 hours (34.5 days) in space. He served as a mission specialist on STS-51 (September 12-22, 1993), was the Orbiter flight engineer (MS-2) on STS-65 (July 8-23, 1994), and was a mission specialist on STS-79 (September 16-26, 1996).
On STS-51, the crew of five aboard Space Shuttle Discovery deployed the U.S. Advanced Communications Technology Satellite (ACTS), and the Shuttle Pallet Satellite (SPAS) with NASA and German scientific experiments aboard. Walz also participated in a 7-hour space walk (EVA) to evaluate tools for the Hubble Space Telescope servicing mission. Following 158 orbits of the Earth, the mission concluded with the first night landing at the Kennedy Space Center. Mission duration was 9 days, 22 hours, and 12 minutes.
On STS-65, the crew of seven aboard Space Shuttle Columbia flew the second International Microgravity Laboratory (IML-2) spacelab module. During the 15-day flight the crew conducted more than 80 experiments focusing on materials and life sciences research in microgravity. The mission completed 236 orbits of the Earth, traveling 6.1 million miles, setting a new flight duration record for the Shuttle program.
Most recently, on STS-79, the six member crew aboard the Shuttle Atlantis docked with the Russian MIR station, delivered food, water, U.S. scientific experiments and Russian equipment, and exchanged NASA long duration crewmembers - bringing John Blaha to Mir and returning Shannon Lucid to Earth. During this mission, the Atlantis/Mir complex set a record for docked mass in space. STS-79 was the first flight of the double Spacehab module, and landed at KSC after a highly successful flight of 10 days 3 hours and 13 minutes.

STS-108 cargo bay payload was dominated by the Raffaello (MPLM-2) logistics module with 4 RSP and 8 RSR resupply racks. Also in the cargo bay were the MACH-1 and LMC experiment trusses flown under the Goddard small payloads program. MACH-1 was an MPESS-type Hitchhiker bridge carrying the CAPL-3 capillary thermal control experiment on top. On its forward side was the Starshine-2 launch canister, the CAPL-3 avionics plate, the Hitchhiker avionics plate, and the SEM-15 canister. On the aft side was the G-761 canister containing experiments from Argentina, the PSRD synchrotron detector (a prototype for the AMS antimatter experiment which will fly on Station later), and the COLLIDE-2 and SEM-11 canisters. The SEM (Space Experiment Modules) are collections of high school experiments. LMC, the Lightweight MPESS Carrier carried four canisters with materials science and technology experiments: SEM-12, G-785, G-064 and G-730. In addition, an adapter beam on the starboard sidewall carried G-221 and G-775, with materials science and biology experiments.
Raffaello was transferred back to the Shuttle payload bay on December 14. Endeavour undocked from the Station at 17:28 UTC on December 15 and made a half loop around the station before making a small separation burn at 1822 UTC. The Starshine-2 reflector satellite was ejected from the MACH-1 bridge in Endeavour's payload bay at 1502 UTC on December 16. Endeavour landed on runway 15 at Kennedy Space Center at 1755 UTC on December 17. The Expedition 3 crew of Culbertson, Dezhurov and Tyurin returned to Earth aboard Endeavour, leaving the Expedition 4 crew of Onufrienko, Bursch and Walz in charge of the Station.
