Early Life
Gregory Bruce Jarvis was born in Detroit, Michigan, on August 24, 1944. Growing up, he was heavily involved with a variety of sports and was also a classical guitarist. His father, Greg Jarvis, and mother, Lucille Ladd, divorced when he was in college at the State University of New York. He studied electrical engineering and received his bachelor's degree in 1967. He then pursued a Master's degree in Electrical Engineering at Northeastern. After graduation, he served in the Air Force for four years, attaining the rank of captain.

Work at Hughes Aircraft
In 1973, Jarvis joined Hughes Aircraft Company, where he worked as an engineer on various satellite programs. Over the next few years, he served as an engineer for the MARISAT Program, which consisted of a set of maritime communications satellites. He then went on to work on communications systems for military use before joining the Advanced Program Laboratory to work on the LEASAT systems. The technology provided synchronous communications for a variety of applications. In 1984, Jarvis, along with 600 other Hughes engineers, applied to become payload specialists for NASA flights.

Work With NASA
Gregory Jarvis was accepted for training by NASA in 1984. He was listed as a payload specialist, a category including people trained by commercial or research institutions to do specific space shuttle flights. His main interest was the effect of weightlessness on fluids. Jarvis was put on flight status and slated to go into space in 1985. However, his place was taken by Jake Garn, a U.S. senator who wanted to fly into space. Another senator, Bill Nelson, stepped in and also wanted to fly, so Jarvis' flight was postponed until 1986.
Jarvis was assigned as a payload specialist on STS-51L aboard the Challenger shuttle. It would be the 25th shuttle mission carried out by NASA and included the first teacher in space, Christa McAuliffe. Jarvis was tasked to study fluids in space, in particular, the effects on liquid-fueled rockets, as part of a fluid dynamics experiment. His specific duties were to test the reaction of satellite propellants to shuttle maneuvers.
For 51L, Challenger carried a tracking and data relay satellite (TDRS), as well as the Spartan Halley shuttle-pointed tool for astronomy. Jarvis and the others would be responsible for their deployment, while colleague Christa McAuliffe would teach lessons from space and attend to a set of student experiments carried into space aboard the shuttle. Although not specifically in the mission plan, astronaut Ronald McNair had brought along his saxophone and had planned to play a short concert from space.

The Challenger Disaster
The space shuttle Challenger was destroyed in an explosion 73 seconds after launch on January 28, 1986. In addition to Gregory Jarvis, crew members Christa McAuliffe, Ron McNair, Ellison Onizuka, Judith A. Resnik, Dick Scobee, and Michael J. Smith were killed in the disaster. After Jarvis' remains were recovered, he was cremated and scattered at sea by his widow, Marcia Jarboe Jarvis.

Personal Life
Gregory Jarvis married Marcia Jarboe in 1968 after they had met in college. They were active in sports, particularly long-distance cycling. They had no children. Marcia worked as a dental assistant.

Honors and Awards
Gregory Jarvis was awarded the Congressional Space Medal of Honor posthumously. There is an engineering building at the State University of New York, Buffalo, named for him, as well as a dam in New York state.
Jarvis, along with other crew members, was the subject of a film called "Beyond the Stars" and a documentary called "For All Mankind," dedicated to the sacrifice made by the Challenger crew.

Biographical Data
GREGORY B. JARVIS (MR.)
PAYLOAD SPECIALIST (DECEASED)
PERSONAL DATA: Born August 24, 1944, in Detroit, Michigan. He is survived by his wife, Marcia. Greg Jarvis was an avid squash player and bicycle rider. He also enjoyed cross country skiing, backpacking, racquet ball, and white water river rafting. For relaxation, he played the classical guitar.

AWARDS: Posthumously awarded the Congressional Space Medal of Honor.
EDUCATION: Graduated from Mohawk Central High School, Mohawk, New York, 1962; received a bachelor of science degree in electrical engineering, State University of New York at Buffalo, 1967; a masters degree in electrical engineering, Northeastern University, Boston, Massachusetts, 1969. Mr. Jarvis also completed all of the course work for a masters degree in management science, West Coast
University, Los Angeles, California.

EXPERIENCE: While pursuing his masters degree at Northeastern, Mr. Jarvis worked at Raytheon in Bedford Massachusetts, where he was involved in circuit design on the SAM-D missile. In July 1969, he entered active duty in the Air Force and was assigned to the Space Division in El Segundo, California. As a Communications Payload Engineer, in the Satellite Communications Program Office, he worked on advanced tactical communications satellites. He was involved in the concept formulation, source selection, and early design phase of the FLTSATCOM
communications payload. After being honorably discharged from the Air Force in 1973, with the rank of Captain, he joined Hughes Aircraft Companys Space and Communications group, where he worked as a Communications Subsystem Engineer on the MARISAT Program. In 1975, he became the MARISAT F-3 Spacecraft Test and Integration Manager. In 1976, the MARISAT F-3 was placed in geosynchronous orbit. Jarvis became a member of the Systems Applications Laboratory in 1976, and was involved in the concept definition for advanced UHF and SHF communications for the strategic forces. Joining the Advanced Program Laboratory in 1978, he began working on the concept formulation and subsequent proposal for the SYNCON IV/LEASAT Program. In 1979, he became the Power/Thermal/Harness Subsystem Engineer on the LEASAT Program. In 1981, he became the Spacecraft Bus System Engineering and in 1982, the Assistant Spacecraft System Engineering Manager. He was the Test and Integration Manager for the F-1, F-2, and F-3 spacecraft and the cradle in 1983, where he worked until the shipment of the F-1 spacecraft and cradle to Cape Kennedy for integration into the Orbiter. Both the F-1 and F-2 LEASAT spacecraft have successfully achieved their geosynchronous positions. Mr. Jarvis worked on advanced satellite designs in the Systems Application Laboratory. He was selected as a payload specialist candidate in July 1984.
NASA EXPERIENCE: Mr. Jarvis was a payload specialist on STS 51-L which was launched from the Kennedy Space Center, Florida, at 11:38:00 EST on January 28, 1986. The crew on board the Orbiter Challenger included the spacecraft commander, Mr. F.R. Scobee, the pilot, Commander M.J. Smith (USN), mission specialists, Dr. R.E. McNair, Lieutenant Colonel E.S. Onizuka (USAF), and Dr. J. A. Resnik, and fellow civilian payload specialist, Mrs. S. C. McAuliffe. The STS 51-L crew died on January 28, 1986 when Challenger exploded after launch.
