Dwayne Brown Headquarters, Washington, DC July 23, 2001 (Phone: 202/358-1726) RELEASE: 01-149 ASTRONAUTS TO TESTIFY FROM SPACE TO U.S. CONGRESS Astronauts living and working aboard the International Space Station, while orbiting more than 200 miles above Earth, will become the first-ever witnesses to present live testimony before Congress during an unprecedented House Science Committee Hearing. The International Space Station is the most complex international endeavor ever undertaken. Still under construction, it is now larger and more capable than any spacecraft ever flown. The space testimonial is scheduled for Wednesday, July 25, at noon. Flight Engineers James Voss and Susan Helms, part of the second crew to live on the station, will provide a brief tour of the facilities, explain construction activities and discuss research capabilities aboard the operational outpost. Astronaut Mary Ellen Weber, a crewmember on the May 2000 space shuttle flight -- the third mission to install components and transfer supplies to the station -- and astronaut Bill Shepherd (Captain, USN), the first American resident and commander on the station, will also testify at the hearing. Weber, who holds a doctorate in physical chemistry, will explain the relevance of space-based experiments and provide personal reflections on research and scientific investigations in space. Shepherd will discuss a typical day in the life of a crewmember on the International Space Station, as well as the challenges involved in constructing, living and working in a permanently inhabited space-based facility. The hearing will be held in Room 2318 of the Rayburn House Office Building on Capitol Hill and is open to the public on a first-come, first-served basis. Testimony from the Expedition Two Crew will be carried live on NASA Television and webcast on NASA's Internet homepage. The hearing will also be taped and replayed on NASA TV.
