F-1 Engine Refurbishing
Propulsion engineers Tim Duquette and Don Nave remove parts from an F-1 engine -- the powerful American rocket engine that launched the Saturn V. Unlike liquid hydrogen and liquid oxygen, which must be kept at extremely cold, cryogenic temperatures, the F-1 burns refined kerosene, or rocket propellant 1 (RP-1), which operates at ambient temperatures. This could provide some advantages, such as more affordable, flexible ground operations. NASA's Marshall Space Flight Center in Huntsville, Ala., managed the development of the original F-1 engine. A team of young Marshall engineers refurbished an F-1 gas generator and are test firing it to record data with modern instrumentation.
