NASA Career
In July 1970, Griggs was employed at the Lyndon B. Johnson Space Center as a research pilot, working on various flight test and research projects in support of NASA programs. In 1974, he was assigned duties as the project pilot for the space shuttle trainer aircraft and participated in the design, development, and testing of those aircraft pending their operational deployment in 1976. He was appointed Chief of the Shuttle Training Aircraft Operations Office in January 1976 with responsibility for the operational use of the shuttle trainer, and held that position until being selected as an astronaut candidate by NASA in January 1978. In August 1979, he completed a one-year training and evaluation period and became eligible for Space Shuttle flight crew assignment.
From 1979 to 1983, Griggs was involved in several Space Shuttle engineering capacities including the development and testing of the Head-Up Display (HUD) approach and landing avionics system, development of the Manned Maneuvering Unit (MMU), and the requirements definition and verification of on-orbit rendezvous and entry flight phase software and procedures. In September 1983 he began crew training as a mission specialist for flight STS-51-D, which flew April 12–19, 1985. During the flight, Mr. Griggs conducted the first unscheduled extravehicular activity (space walk) of the space program. The space walk lasted for over three hours during which preparations for a satellite rescue attempt were completed.
At the time of his death, Griggs was in flight crew training as pilot for STS-33, a dedicated Department of Defense mission, scheduled for launch in November 1989.

Famous quotes containing the words nasa and/or career:
“If we did not have such a thing as an airplane today, we would probably create something the size of NASA to make one.”
—H. Ross Perot (b. 1930)
“What exacerbates the strain in the working class is the absence of money to pay for services they need, economic insecurity, poor daycare, and lack of dignity and boredom in each partner’s job. What exacerbates it in upper-middle class is the instability of paid help and the enormous demands of the career system in which both partners become willing believers. But the tug between traditional and egalitarian models of marriage runs from top to bottom of the class ladder.”
—Arlie Hochschild (20th century)
