EXPERIENCE: From 1979 to 1982, Walz was responsible for analysis of radioactive samples from the Atomic Energy 

Detection System at the 1155th Technical Operations Squadron, McClellan Air Force Base, California. The subsequent year 

was spent in study as a Flight Test Engineer at the USAF Test Pilot School, Edwards Air Force Base, California. From January

1984 to June 1987, Walz served as a Flight Test Engineer to the F-16 Combined Test Force at Edwards Air Force Base, where 

he worked on a variety of F-16C airframe avionics and armament development programs. From July 1987 to June 1990, he 

served as a Flight Test Manager at Detachment 3, Air Force Flight Test Center.

NASA EXPERIENCE: Selected by NASA in January 1990, Walz is a veteran of four space flights, and has logged a total of

231 days in space. He was a mission specialist on STS-51 (1993), was the Orbiter flight engineer (MS-2) on STS-65 (1994), 

was a mission specialist on STS-79 (1996), and served 196 days in space as flight engineer (FE-1) on ISS Expedition-Four 

(2001-2002). Carl also served as the Director for the Advanced Capabilities Division in the Exploration Systems Mission 

Directorate at NASA Headquarters in Washington D.C. He was responsible for a broad range of activities to include Human 

Research, Technology Development, Nuclear Power and Propulsion and the Lunar Robotic Exploration Programs to support the 

Vision for Space Exploration. He retired from NASA on December 5, 2008 to pursue interests in the private sector.

SPACE FLIGHT EXPERIENCE: STS-51 Discovery (September 12-22, 1993). During the mission, the five member crew 

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. The mission was accomplished in 9 days, 22 hours, and 12 minutes.

STS-65 Columbia (July 8-23, 1994). STS-65 flew the second International Microgravity Laboratory (IML-2) spacelab module, 

and carried a crew of seven. 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.

STS-79 Atlantis (September 16-26, 1996). On STS-79 the six member crew aboard Atlantis docked with the Russian MIR

station, delivered food, water, U.S. scientific experiments and Russian equipment, and exchanged NASA long duration 

crewmembers. During the 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 10 days 3 hours and 13 minutes.

Expedition 4 (December 5, 2001 to June 19 2002). The Expedition-4 crew launched on December 5, 2001 aboard the Space 

Shuttle Endeavour, STS-108, and docked with the International Space Station on December 7, 2001. During their 196 days in 

space, the Expedition-4 crew of three (two American astronauts and one Russian cosmonaut) performed flight tests of the station

hardware, conducted internal and external maintenance tasks, robotic control tasks, and conducted numerous experiments in a 

variety of scientific disciplines. Wearing the Russian Orlan spacesuit, Walz logged 6 hours of EVA time with Commander Yury 

Onufrienko as they continued the outfitting of the Russian-supplied Docking Compartment (DC). In addition, Walz logged 5 

hours 52 minutes of EVA time in the U.S. EMU spacesuit in his second spacewalk with flight engineer Dan Bursch, preparing 

the ISS for the S0 truss, delivered by the STS-110 crew. The Expedition-4 crew also performed a Soyuz relocation from the 

FGB nadir to the DC nadir hatch to prepare for the arrival of a new Soyuz capsule. The Expedition-4 crew returned to Earth 

aboard STS-111, with Endeavour landing at Edwards Air Force Base, California, on June 19, 2002.
