Maintaining Hubble Space Telescope performance through in-orbit servicing
The HST system design is described as well as the in-orbit servicing program. In order to verify the feasibility and the design of the HST servicing features, a design verification program, which included 1-g tests and 0-g underwater simulations, was carried out. The major elements of the space support equipment, including the flight support system, the orbital replacement unit carrier, and the solar array carrier, are addressed in detail.
