 Military service
Hart entered on active duty with the United States Air Force Reserve in June 1969. He completed undergraduate pilot training at Moody Air Force Base, Georgia, in December 1970, and from then until 1973, flew F-106 interceptors for the Air Defense Command at Tyndall Air Force Base, Florida, at Loring Air Force Base, Maine, and at Dover Air Force Base, Delaware. In 1973, he joined the New Jersey Air National Guard and continued flying with the Guard until 1985, retiring as Lt. Colonel in 1990. He has logged 3,000 hours flying time, with 2,400 hours in jets.
 NASA experience
Mr. Hart was selected as an astronaut candidate by NASA in January 1978. In August 1979, he completed a 1-year training and evaluation period, making him eligible for flight assignment on future Space Shuttle crews. Hart was also member of the support crews for STS-1, STS-2, STS-3, and STS-7. He was Ascent and Orbit CAPCOM with the Mission Control Team for those flights. He flew as a mission specialist on STS-41-C (April 6-April 13, 1984) and has logged a total of 168 hours in space.
 Civilian Experience
From 1968 to 1978, Hart was employed as a member of the Technical Staff of Bell Telephone Laboratories. His principal duties included electrical and mechanical design responsibilities for a variety of electronic power equipment used in the Bell System. He has received 2 patents.
After leaving NASA, he was the Director of Engineering and Operations for AT&T's satellite network. He is currently a member of the Engineering faculty at Lehigh University.
 STS 41-C
STS 41-C Challenger was launched from Kennedy Space Center, Florida, on April 6, 1984. The crew included Captain Robert Crippen (spacecraft commander), Mr. F. R. (Dick) Scobee (pilot), and fellow mission specialist, Dr. George D. Nelson and Dr. James van Hoften. During this mission, the crew successfully deployed the Long Duration Exposure Facility (LDEF); retrieved the ailing Solar Maximum Satellite, repaired it on board Challenger, and replaced it in orbit using the robot arm called the Remote Manipulator System (RMS). The mission also included flight testing of Manned Maneuvering Units (MMUs) in two extravehicular activities (EVAs); operation of the Cinema 360 and IMAX Camera Systems, as well as a Bee Hive Honeycomb Structures student experiment. Mission duration was 7 days before landing at Edwards Air Force Base, California, on April 13, 1984.
