After receiving his commission at the University of Colorado through the four year ROTC program, Onizuka entered on active duty with the United States Air Force as a distinguished military graduate in Janurary 1970. As an aerospace flight test engineer with the Sacramento Air Logistics Center at McClellan Air Force Base, California, he participated in flight test programs and systems safety engineering for the F-84, F-100, F-105, F-lll, EC-121T, T-33, T-39, T-28, and A-l aircraft. He attended the USAF Test Pilot School from August 1974 to July 1975, receiving formal academic and flying instruction in performance, stability and control, and systems flight testing of aircraft. In July 1975 he was assigned to the Air Force Flight Test Center at Edwards Air Force Base, California, serving on the USAF Test Pilot School staff initially as squadron flight test engineer and later as chief of the engineering support section in the training resources branch. His duties involved instruction of USAF Test Pilot School curriculum courses and management of all flight test modifications to general support fleet aircraft (A-7, A-37, T-38, F-4, T-33, and NKC-135) used by the test pilot school and the flight test center. He logged more than 1,700 hours flying time.

Selected as an astronaut candidate by NASA in January 1978, he completed a one year training and evaluation period in August 1979. He subsequently worked on orbiter test and checkout teams and launch support crews at the Kennedy Space Center for STS-l and STS-2. He worked on software test and checkout crew at the Shuttle Avionics and Integration Laboratory (SAIL), and has supported numerous other technical assignments ranging from astronaut crew equipment/orbiter crew compartment coordinator to systems and payload development.

He first flew as a mission specialist on STS 51-C, the first Space Shuttle Department of Defense mission, which launched from Kennedy Space Center, Florida, on January 24, 1985. He was accompanied by Captain Thomas K. Mattingly (spacecraft commander), Colonel Loren J. Shriver (pilot), fellow mission specialist, Colonel James F. Buchli, and Lieutenant Colonel Gary E. Payton (DOD payload specialist). During the mission, Onizuka was responsible for the primary payload activities, which included the deployment of a modified Inertial Upper Stage (IUS). STS 51-C Discovery completed 48 orbits of the Earth before landing at Kennedy Space Center, Florida, on January 27, 1985. With the completion of this flight he logged a total of 74 hours in space.

Lieutenant Colonel Onizuka was a mission 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 spacecraft commander Mr. F. R. Scobee, the pilot, Commander M. J. Smith (USN), fellow mission specialist, Dr. R. E. McNair and Dr. J. A. Resnik, as well as two civilian payload specialist, Mr. G. B. Jarvis and Mrs. S. C. McAuliffe. The STS 51-L crew died on January 28, 1986, after Challenger exploded 1 minute 13 seconds after launch.
