EXPERIENCE: Following graduation from Georgia Tech in 1982, Scott worked as an associate scientist for the Lockheed-Georgia Company, Marietta, Georgia, where he performed background studies and analyses for experiments related to aerospace technology to validate advanced scientific concepts. In 1983, he graduated from Undergraduate Pilot Training at Williams Air Force Base, Arizona. From 1984 to 1987, he flew as a T-38 instructor pilot and performed research and development for the Human Resources Laboratory at Williams Air Force Base. The following two years were spent as an operational F-15 Eagle Fighter Pilot in the 22nd Tactical Fighter Squadron stationed at Bitburg Air Base in Germany. In 1990, Scott attended the United States Air Force Test Pilot School at Edwards Air Force Base, California, and was subsequently assigned as a test pilot flying A-7s and T-38s for the 6512th Test Squadron at Edwards. Additionally, from 1985 to 1989, Scott served as an adjunct professor at Embry Riddle University where he conducted graduate level courses in aircraft design, aircraft propulsion and rocket propulsion. In 1991, as a professor for California State University, Fresno, he conducted graduate level courses in mechanical engineering including advanced stability and control. Scott has logged more than 4,000 hours in over 50 different aircraft.

NASA EXPERIENCE: Selected as a pilot by NASA in March 1992, Scott reported to the Johnson Space Center in August 1992 . He successfully completed a year of initial training and assignments since then include: working technical issues for the Astronaut Office Operations Development Branch; support crew at the Kennedy Space Center for Shuttle launches and landings. A veteran of two space flights, he has logged over 617 hours in space. He served as pilot on STS-75 in 1996 and STS 82 in 1997. Horowitz is assigned to STS-101, the third Shuttle assembly mission for the International Space Station. Launch is scheduled for early 2000.

SPACE FLIGHT EXPERIENCE: STS-75 launched February 22, 1996 and landed back at the Kennedy Space Center on March 9, 1996. Principal payloads on STS-75 were the reflight of 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 flight was completed in 252 orbits covering 6.5 million miles in 377 hours and 40 minutes.

STS-82, the second Hubble Space Telescope (HST) maintenance mission, launched at night on February 11 and returned to a night landing at Kennedy Space Center on February 21, 1997. During the flight, the crew retrieved and secured the HST in Discovery's payload bay. In five space walks, two teams installed two new spectrometers and eight replacement instruments, as well as replacing insulation patches over three compartments containing key data processing, electronics and scientific instrument telemetry packages. Following completion of upgrades and repairs, HST was redeployed and boosted to a higher orbit. The flight was completed in 149 orbits covering 3.8 million miles in 9 days, 23 hours, 37 minutes.
