Ellison Shoji Onizuka (鬼塚 承次 Onizuka Shōji, June 24, 1946 – January 28, 1986) was an American astronaut from Kealakekua, Hawaii, who successfully flew into space with the Space Shuttle Discovery on STS-51-C. He died in the destruction of the Space Shuttle Challenger, on which he was serving as Mission Specialist for mission STS-51-L. He was the first Asian American and the first person of Japanese ancestry to reach space.
Born June 24, 1946, Onizuka was the oldest son and second-youngest child of the late Masamitsu and Mitsue Onizuka. He was a Buddhist. He had two older sisters, Shirley and Norma, and a younger brother, Claude, who became the family spokesman after the Challenger disaster. Growing up, Ellison was an active participant in FFA, 4-H, and the Boy Scouts of America, where he reached the level of Eagle Scout.
Onizuka graduated from Konawaena High School in 1964. He received a Bachelor of Science degree in Aerospace Engineering in June 1969, and a Master of Science degree in that field in December of the same year, from the University of Colorado at Boulder. He participated in U.S. Air Force ROTC during his time there and is an alumnus of Triangle Fraternity.
Onizuka married Lorna Leiko Yoshida on June 7, 1969, while completing his studies at the University of Colorado. They had two daughters, Janelle Onizuka-Gillilan (b. 1969) and Darien Lei Shizue Onizuka-Morgan (b. 1975).
Air Force career
On January 15, 1970, Onizuka entered active duty with the United States Air Force, where he served as a flight test engineer and as a test pilot. At the Sacramento Air Logistics Center at McClellan Air Force Base. He worked in test flight programs and systems security engineering for the F-84, F-100, F-105, F-111, EC-121T, T-33, T-39, T-28, and A-1.
From August 1974 to July 1975, Onizuka attended the U.S. Air Force Test Pilot School. In July 1975, he was assigned to the Flight Test Center at Edwards Air Force Base in California. He became a squadron flight test engineer at the USAF Test Pilot School, and later worked as a manager for engineering support in the training resources division. His duties there consisted of course instruction and management of the airship fleet (A-7, A-37, T-38, F-4, T-33, and NKC-135) being used for the Test Pilot School and Flight Test Center. While at the school, he registered more than 1,700 flight hours.
Onizuka was selected for the astronaut program in January 1978, and completed one year of evaluation and training in August 1979. Later, he worked in the experimentation team, Orbiter test team, and launch support crew at Kennedy Space Center for the STS-1 and STS-2. At NASA, he worked on the Shuttle Avionics Integration Laboratory (SAIL) test and revision software team.
Onizuka's first space mission took place on January 24, 1985, with the launch of mission STS 51-C on Space Shuttle Discovery, the first space shuttle mission for the Department of Defense. He was accompanied by Commander Ken Mattingly, Pilot Loren Shriver, fellow Mission Specialist James Buchli, and Payload Specialist Gary E. Payton. During the mission, he was responsible for the activities of the primary payloads, which included the unfolding of the Inertial Upper Stage (IUS) surface. After 48 orbits around the Earth, Discovery landed at Kennedy Space Center on January 27, 1985. He had completed a total of 74 hours in space.
Onizuka was assigned to the mission STS 51-L on the Space Shuttle Challenger that took off from Kennedy Space Center at 11:38:00 EST (16:38:00 UTC) on January 28, 1986. The other Challenger crew members were commander Dick Scobee, pilot Michael J. Smith, mission specialists Ronald McNair, Judith Resnik, and payload specialists Gregory Jarvis and Christa McAuliffe. It was destroyed when a flame jet leaking from a solid rocket booster ruptured the liquid hydrogen fuel tank 73 seconds after launch. All seven crew members were killed.
Following the Challenger disaster, examination of the recovered vehicle cockpit revealed that three of the crew members Personal Egress Air Packs were activated: those of Onizuka, mission specialist Judith Resnik, and pilot Michael Smith. The location of Smith's activation switch, on the back side of his seat, means that either Resnik or Onizuka could have activated it for him. This is the only evidence available from the disaster that shows Onizuka and Resnik were alive after the cockpit separated from the vehicle. However, if the cabin had lost pressure, the packs alone would not have sustained the crew during the two-minute descent.
Onizuka was buried at the National Memorial Cemetery of the Pacific in Honolulu, Hawaii. At the time of his death, he held the rank of lieutenant colonel. Posthumously, he was promoted to the rank of colonel.
Memberships and distinctions
Onizuka belonged to the following organizations: Society of Flight Test Engineers, the Air Force Association, the American Institute of Aeronautics and Astronautics, Tau Beta Pi, Sigma Tau, Arnold Air Society, and Triangle Fraternity.
Among his distinctions are the Air Force Commendation Medal, Air Force Meritorious Service Medal, Air Force Outstanding Unit Award, Air Force Organizational Excellence Award, and National Defense Service Medal. He was posthumously awarded the Congressional Space Medal of Honor.
Onizuka Air Force Station in Sunnyvale, California, Onizuka Village family housing on Hickam Air Force Base and the Ellison S. Onizuka Space Center at Kona International Airport in the Kona district of Hawaiʻi island where he was born and raised, are dedicated to him.
Little Tokyo in Los Angeles, California also has a street named after him, as does the street surrounding Whitcomb Elementary school in Clear Lake City, Houston, Texas, where his daughters attended. It also named its library the Onizuka Memorial Library. (At the time of the Challenger disaster, his older daughter, Janelle, attended Clear Lake High School. His younger daughter, Darien Lei, was at Whitcomb.) In addition, Onizuka Street in Little Tokyo has a scale replica of the Challenger as a memorial, and a permanent memorial to Onizuka is located in the lobby of the Hompa Hongwanji Buddhist Temple. 
The Onizuka Center for International Astronomy, named in Onizuka's honor, is the mid-level support and visitor complex for the Mauna Kea Observatories in Hawaii. It includes a Visitor Information Station as well as dining, lodging, office, and maintenance facilities for observatory staff and astronomers. A plaque of his face is mounted on a boulder by the entrance to the Visitor Information Station. Triangle Fraternity has the Ellison Onizuka Young Alumnus Award in tribute to him.
The Engineering Center at the University of Colorado at Boulder has a conference room named after him.
