Duffy, resides in Hingham, Massachusetts. His father, Mr. Daniel E. Duffy, is deceased. Her parents, Mr. & Mrs. John J. Helms, reside in Ft. Myers, Florida.

EDUCATION:
Graduated from Rockland High School, Rockland, Massachusetts, in 1971; received a bachelor of science degree in mathematics from the United States Air Force (USAF) Academy in 1975, and a master of science degree in systems management from the University of Southern California in 1981.

ORGANIZATIONS:
Member of the United States Air Force Academy Association of Graduates, the Air Force Association, and the Association of Space Explorers.

SPECIAL HONORS:
Distinguished Graduate of USAF Undergraduate Pilot Training where he was awarded the UPT Flying Training Award. Distinguished Graduate of USAF Test Pilot School Class 82B. Awarded the Defense Meritorious Service Medal, Defense Superior Service Medal, Air Force Meritorious Service Medal, the Air Force Commendation Medal, and NASA Space Flight Medals.

EXPERIENCE:
Duffy graduated from the USAF Academy in 1975. He completed Undergraduate Pilot Training at Columbus Air Force Base, Mississippi, in 1976, and was selected to fly the F-15. He was stationed at Langley Air Force Base, Virginia, until 1979. At the end of 1979 he transferred to Kadena Air Base, Okinawa, Japan. He flew F-15's there until 1982 when he was selected to attend the U.S. Air Force Test Pilot School. Following graduation, he served as the Director of F-15 Tests at Eglin Air Force Base, Florida.

He has logged over 4,000 hours of flight time in more than 25 different aircraft.

NASA EXPERIENCE:
Selected by NASA in June 1985, Duffy became an astronaut in July 1986. Since then, he has participated in the development and testing of computer software to be used on Shuttle flights, served as Technical Assistant to the Director of Flight Crew Operations, developed displays and flight crew procedures used during the ascent phase, served as spacecraft communicator (CAPCOM) in Mission Control during numerous Space Shuttle missions, and also worked on Space Station issues. A veteran of three space flights, he has logged over 667 hours in space. Duffy was the pilot on STS-45 (March 24 to April 2, 1992), the first of the ATLAS series of missions to address the atmosphere and its interaction with the Sun. He also was the pilot on STS-57 (June 21 to July 1, 1993). Mission highlights included retrieval of the European Retrievable Carrier with the Shuttle's robotic arm, a spacewalk by two crew members, and an assortment of experiments in the first flight of the Spacehab middeck augmentation module. Most recently, Duffy commanded a six-man crew aboard Endeavour on STS-72 (January 11-20, 1996). During the 9-day flight the crew aboard Endeavour retrieved the Space Flyer Unit (launched from Japan 10-months earlier), deployed and retrieved the OAST-Flyer, and conducted two spacewalks to demonstrate and evaluate techniques to be used in the assembly of the International Space Station.

Col. Duffy currently serves as Assistant Director (Technical), Johnson Space Center. In this role he assists the Center Director in the direction and management of JSC's resources, functions, and programs and projects assigned to the Center.

Period: 92.28 min. ISS Logistics flight. 100th shuttle flight. Launch delayed from October 6. STS-92 brought the Z-1 Truss (mounted on a Spacelab pallet), Control Moment Gyros, Pressurised Mating Adapter-3 (PMA-3) and two DDCU (Heat pipes) to the International Space Station.

    The RSRM-76 solid rocket boosters separated at 23:19 GMT and main engine cut-off (MECO) came at 23:25 GMT. External tank ET-104 separated into a 74 x 323 km x 51.6 deg orbit. At apogee at 00:01 GMT on Oct 12, Discovery's OMS engines fired to raise perigee to a 158 x 322 km x 51.6 deg orbit; ET-104 re-entered over the Pacific around 00:30 GMT. At Oct 12 on 03:01 GMT the NC1 burn raised the orbit to 180 x 349 km; NC3 on Oct 12 to 311 x 375 km; and the TI burn at 14:09 GMT on Oct 13 to 375 x 381 km x 51.6 deg. Discovery's rendezvous with the International Space Station came at 15:39 GMT on Oct 13, with docking at 17:45 GMT. The spaceship docked with PMA-2, the docking port on the +Y port of the Space Station's Unity module. Hatch was open to PMA-2 at 20:30 GMT the same day.

    STS-92 Cargo Manifest

    • Bay 1-2: Orbiter Docking System + 3 EMU spacesuits
    • Bay 5 Port: Adapter Beam with DDCU-HP control unit
    • Bay 5 Starboard: Adapter Beam with DDCU-HP control unit
    • Bay 7-8: Spacelab Pallet MD003 with PMA-3
    • Bay 10-12: ISS Z1 first segment of the space station truss
    • Bay 13 Adapter Beam with IMAX Cargo Bay Camera
    • Sill: Canadarm RMS 301

    Total payload bay cargo: ca. 14,800 kg

    The Z1 first segment of the space station truss was built by Boeing/Canoga Park and was 3.5 x 4.5 meters in size. It was attached to the +Z port on Unity. Z1 carried the control moment gyros, the S-band antenna, and the Ku-band antenna.

    PMA-3, built by Boeing/Huntington Beach, was docked to the -Z port opposite Z1. PMA-3 was installed on a Spacelab pallet for launch.

    On October 14 at 16:15 GMT the Z1 segment was unberthed from the payload bay and at around 18:20 GMT it was docked to the zenith port on the Unity module.

    On October 15 at 14:20 GMT the ODS airlock was depressurised, beginning a spacewalk by Bill McArthur and Leroy Chiao. Official NASA EVA duration (battery power to repress) was 6 hours 28 minutes.

    The second spacewalk was on October 16, with Jeff Wisoff and Mike Lopez-Alegria. The suits went to battery power at 14:15 GMT and Wisoff left the airlock at 14:21 GMT. Repressurisation began at 21:22 GMT for a duration of 7 hours 07minutes.

    Leroy Chiao and Bill McArthur began the third STS-92 EVA at 15:30 GMT on October 17, completing their work at 22:18 GMT for a total time of 6 hours 48 minutes.

    After the spacewalk, Discovery completed the second of the three station reboosts scheduled for STS-92. They fired reaction control system jets in a series of pulses of 1.4 seconds each, over a 30-minute period, gently raising the station's orbit by about 3.1 km.

    The last of four successful spacewalks began on 18 October at 16:00 GMT and ended at 22:56 GMT, lasting 6 hours and 56 minutes. Jeff Wisoff and Mike Lopez-Alegria each jetted slowly through space above Discovery's cargo bay.

    After the space walk, Discovery completed the third and final reboost of the space station.

    On 19 October the astronauts worked within the ISS. They completed connections for the newly installed Z1 external framework structure and transferred equipment and supplies for the Expedition One first resident crew of the Station. The crew also tested the four 290-kg gyroscopes in the truss, called Control Moment Gyros, which will be used to orient the ISS as it orbits the Earth. They will ultimately assume attitude control of the ISS following the arrival of the U.S. Laboratory Destiny. The tests and the transfer of supplies into the Russian Zarya Module took longer than expected. As a result, the crew's final departure from the Station's Unity module was delayed. Melroy and Wisoff took samples from surfaces in Zarya to study the module's environment. They then unclogged the solid waste disposal system in the Shuttle's toilet, which was restored to full operation after a brief interruption in service.

    Discovery undocked from the ISS at 16:08 GMT on 20 October. The final separation burn was executed about 45 minutes after undocking. The crew had added 9 tonnes to the station's mass, bringing it to about 72 tonnes. The return to earth, planned for 22 October, was delayed repeatedly due to high winds at the Kennedy landing site. The landing was finally made at Edwards Air Force Base, California, on October 24, at 22:00 GMT.
