Carl E. Walz

Carl E. Walz (Colonel, USAF, Ret.) 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. Selected by NASA in January 1990, Walz is a veteran of four space flights, and has logged 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 as flight engineer (FE-1) on ISS Expedition-Four (2001-2002). Carl Walz and fellow astronaut Dan Bursch currently hold the U.S. space flight endurance record of 196 days in space. Currently, Walz is the Acting Director for the Advanced Capabilities Division in the Exploration Systems Mission Directorate at NASA Headquarters in Washington D.C. He is 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. His space flight experience includes 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. The 196 days in space established a U.S. space flight endurance record for Carl Walz and crew mate Dan Bursch. 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. His full bio is at

Paul Eckert, Robert Dickman and Carl Walz were the guests for this special program to discuss making the VSE a long-term reality as well as the coming AIAA Dec. 4-6 2nd Space Exploration Conference which will be held in Houston. We started the panel discussion with Bob Dickman explaining why the AIAA has this conference and its role in helping to establish the VSE as a long-term reality for the nation. Paul Eckert of Boeing was next and he went through the conference agenda with us, focusing on the commercial panel and commercial opportunities stemming from the VSE.
