His technical assignments in the Astronaut Office have included flight software verification in the Shuttle Avionics Integration Laboratory (SAIL), participation in the development of retrieval techniques for the Tethered Satellite System (TSS), Remote Manipulator System (RMS), and International Space Station (ISS) robotics support. From the Spring of 1996 to the end of 1998, he was Head of the Astronaut Office Robotics Branch. During 1988 he attended the Empire Test Pilot School in Boscombe Down, England, from where he graduated as a test pilot in December 1988.
Claude holds a commission as captain in the Swiss Air Force and, during leave periods in Switzerland, maintains proficiency in the Northrop F-5E aircraft. He has logged 5,400 hours flying time--including 3,800 hours in jet aircraft.
A veteran of three space flights, Claude has logged more than 828 hours in space. He flew on STS-46 in 1992, STS-61 in 1993, and STS-75 in 1996. Claude is assigned to STS-104, the third Hubble Space Telescope (HST) servicing mission. In order to install new instruments and to upgrade systems to enhance the scientific capabilities of the orbiting HST, a record six spacewalks are scheduled during the mission. Launch is targeted in early 2000.
STS-61 Endeavour was the first Hubble Space Telescope (HST) servicing and repair mission. STS-61 launched at night from the Kennedy Space Center, Florida, on December 2, 1993. During the 11-day flight, the HST was captured and restored to full capacity through a record five space walks by four astronauts. After having traveled 4,433,772 miles in 163 orbits of the Earth in 259 hours, 59 minutes.
STS-75 Columbia (February 22 to March 9, 1996) was a 15-day flight, with principal payloads being the reflight of the Tethered Satellite System (TSS) and the third flight of the United States Microgravity Payload (USMP-3). The TSS successfully demonstrated the ability of tethers to produce electricity. The TSS experiment produced a wealth of new information on the electrodynamics of tethers and plasma physics before the tether broke at 19.7 km, just shy of the 20.7 km goal. The crew also worked around the clock performing combustion experiments and research related to USMP-3 microgravity investigations used to improve production of medicines, metal alloys, and semiconductors. The mission was completed in 252 orbits covering 6.5 million miles in 377 hours and 40 minutes.
