Former NASA astronaut Steven R. Nagel, who served as a mission specialist on his first space shuttle flight, pilot on his second and commanded his final two, died Aug. 21 after a long illness.
According to a release from NASA, he was 67 years old.
After his last shuttle flight, Nagel became deputy director for operations development in the Reliability and Quality Assurance Office at NASA'sJohnson Space Center in Houston. He subsequently served as a research pilot, chief of aviation safety and deputy chief of JSC's Aircraft Operations Division.
"It will always be my honor to know Steve," said Brian Kelly, director of Flight Operations. "He blessed our lives in many ways. His humor, positive approach to life, and constant smile is something we will all cherish. His service to our great nation and NASA is inspirational."
Nagel was born Oct, 27, 1946, in Canton, Ill.
Nagel received his commission in 1969 through the Air Force Reserve Officer Training Corps program at the University of Illinois. He completed pilot training at Laredo Air Force Base, Texas, in February 1970, and then F-100 training at Luke Air Force Base, Arizona. From October 1970 to July 1971, Nagel flew F-100s with the 68th Tactical Fighter Squadron at England Air Force Base, Louisiana.
Nagel served for a year as a T-28 instructor for the Laotian Air Force at Udorn, Thailand. He became A-7D instructor pilot and flight examiner at England Air Force Base, Louisiana. in October 1972. He attended the USAF Test Pilot School at Edwards Air Force Base, California, from February to December 1975.
In January 1976, he was assigned to the 6512th Test Squadron at Edwards. As a test pilot, he worked on various projects, including the F-4 and A-7D. He logged more than 12,600 hours flying time, including 9,640 hours in jet aircraft.
Nagel became a NASA astronaut in August 1979. Assignments included backup T-38 chase pilot for STS-1; support crew and backup entry spacecraft communicator for STS-2; and support crew and primary entry CAPCOM for STS-3.
He first flew in space as a mission specialist on Discovery's STS- 51G, launched June 17, 1985. During the flight, the crew deployed three communications satellites, for Mexico, the Arab League and AT&T's Telstar. They used Discovery's arm to deploy and 17 hours later retrieve the Spartan x-ray astronomy satellite.
Nagel flew as pilot on Challenger for STS-61A, the West German D- 1 Spacelab mission, launched Oct. 30, 1985. More than 75 scientific experiments were completed in physiological sciences, materials processing, biology and navigation during the 7-day, 44-minute mission.
Nagel commanded STS-37 on his third flight, launched on Atlantis April 5, 1991. During the almost six-day mission, the crew deployed the Gamma Ray Observatory (GRO) to explore gamma ray sources throughout the universe. The flight included two spacewalks by Mission Specialists Jerry L. Ross and Jerome Apt. One was the first successful unscheduled spacewalk, to free a stuck antenna on GRO.
Nagel was commander of STS-55, the German D-2 Spacelab mission on Columbia launched April 26, 1993. The 10-day flight carried 89 experiments in materials processing, life sciences, robotics, technology, astronomy and Earth mapping.
Nagel logged a total of 723 hours in space.
Nagel retired from the Air Force as a colonel Feb. 28, 1995, and formally left the Astronaut Office the next day to join the Safety, Reliability, and Quality Assurance Office at Johnson Space Center.
