JSC2005-E-22364 (14 June 2005) --- Astronaut John L. Phillips, Expedition 11 NASA ISS science officer and flight engineer, testifies via video screen before the House Subcommittee on Space and Aeronautics chaired by Rep. Ken Calvert (R-Calif.), as he orbited Earth onboard the International Space Station (ISS) at a speed of five miles a second. Phillips was approximately 220 statute miles above Earth, but his radio transmissions were routed to a Tracking and Data Relay Satellite (TDRS) in geostationary orbit at an altitude of about 22,300 miles.
