American aerospace engineers

John Cornelius Houbolt (April 10, 1919 – April 15, 2014) was an aerospace engineer credited with leading the team behind the lunar orbit rendezvous (LOR) mission mode, a concept that was used to successfully land humans on the Moon and return them to Earth. This flight path was chosen for the Apollo program in July 1962. The critical decision to use LOR was viewed as vital to ensuring that man reached the Moon by the end of the decade as proposed by President John F. Kennedy. In the process, LOR saved time and billions of dollars by efficiently using the rocket and spacecraft technologies.

Abraham "Abe" Silverstein (September 15, 1908 – June 1, 2001) was an American engineer who played an important part in the United States space program. He was a longtime manager at the National Aeronautics and Space Administration (NASA) and its predecessor, the National Advisory Committee for Aeronautics (NACA). He was instrumental in the planning of the Apollo, Ranger, Mariner, Surveyor, and Voyager missions, and named the Apollo program after the Greek and Roman God.

Captain Robert C. Truax (USN) (September 3, 1917 – September 17, 2010) was an American rocket engineer in the United States Navy, and companies such as Aerojet and Truax Engineering, which he founded. Truax was a proponent of low-cost rocket engine and vehicle designs.

Henry Charles Gordon (December 23, 1925 – September 24, 1996), (Col, USAF), was an American aeronautical engineer, U.S. Air Force officer, test pilot, and astronaut in the X-20 Dyna-Soar program.

Robert J. "Bob" Parks (April 1, 1922 – June 3, 2011) was an American aerospace engineer and pioneer in the space program where he was intricately involved and/or directed for some of the most historic and important U.S. unmanned space missions. Over a 40-year tenure at the Jet Propulsion Laboratory (JPL/NASA), located in Pasadena, California, Parks’ impact was essential to helping the United States lead the world in space exploration. He served as Guidance Engineer for Explorer 1, the first successfully launched satellite by the United States. He directed the initial flyby missions to the Moon (Ranger 7, 8 and 9 Missions), the first soft landing on the Moon (Surveyor Lunar Lander), Earth's first successful mission to another planet (Mariner 2 to Venus) and initial missions to Mars, Saturn, Jupiter and Uranus.
Parks concluded his career as Deputy Director of the JPL/NASA and retired in 1987. Some of the awards he received for his work include the NASA Exceptional Service Medal (1967), the Stuart Ballantine Medal (1967), the Goddard Astronautics Award (1980) and the Caltech Distinguished Alumni Award in 1982.

Dale Dehaven Myers (January 8, 1922 – May 19, 2015) was an American aerospace engineer who was Deputy Administrator of NASA, serving between October 6, 1986, and May 13, 1989. He was born in Kansas City, Missouri, and graduated with a Bachelor of Science degree in aeronautical engineering from the University of Washington in Seattle in 1943.

Thomas Victor Jones (July 21, 1920 – January 7, 2014) was an American businessman. He served as the chairman and chief executive officer of Northrop Corporation.
