The Superfluid Helium On-Orbit Transfer (SHOOT) Flight Demonstration was designed to demonstrate the technology for resupplying space helium dewars on orbit. Secondarily SHOOT developed a number of components useful to other satellites using superfluid helium. SHOOT was launched on the Space Shuttle Endeavour as part of mission STS-57 on June 21, 1993. On orbit operations were conducted in three stages: pump down of the superfluid and electronics checkout, initial ground controlled helium transfers, and an astronaut controlled transfer. An overview of the SHOOT mission is given. A summary of experiences with a number of flight components developed specifically for SHOOT is presented. Questions that were answered by the flight are discussed.
