SCARBOROUGH, Maine (AP) — John C. Houbolt, an engineer whose contributions to the U.S. space program were vital to NASA's successful moon landing in 1969, has died. He was 95.
Houbolt's family confirmed his death Tuesday at a Maine nursing home of complications from Parkinson's disease.
As NASA describes on its website, while under pressure during the U.S.-Soviet space race, Houbolt was the catalyst in securing U.S. commitment to the science and engineering theory that eventually carried the Apollo crew to the moon and back safely.
His efforts in the early 1960s are largely credited with convincing NASA to focus on the launch of a module carrying a crew from lunar orbit, rather than a rocket from earth or a space craft while orbiting the planet.
