The FSS will berth, secure and furnish power to Hubble and also contains the soft capture mechanism to be attached to the telescope. Upon completion of STS-125, the Hubble will provide even deeper and more detailed views of the Universe. The STS-125 mission will be the final space shuttle mission to the Hubble Space Telescope.

KENNEDY SPACE CENTER, FLA. - Workers in KSC's Vertical Processing Facility make final adjustments to the Flight Support System (FSS) for STS-82, the second Hubble Space Telescope servicing mission. The FSS is reusable flight hardware that provides the mechanical, structural and electrical interfaces between HST, the space support equipment and the orbiter for payload retrieval and on-orbit servicing. Liftoff aboard Discovery is targeted Feb. 11 with a crew of seven.

KENNEDY SPACE CENTER, FLORIDA STS-82 PREPARATIONS VIEW --- In the Kennedy Space Center (KSC) Vertical Processing Facility (VPF), the STS-82 crew members familiarize themselves with some of the hardware they will be handling on the second servicing mission to the Hubble Space Telescope (HST). Looking over the Flight Support System (FSS) Berthing and Positioning System (BAPS) ring are astronauts Joseph R. Tanner (far left), Mark C. Lee (third left) and Gregory J. Harbaugh (fourth left); along with several HST processing team members. Tanner, Lee and Harbaugh, along with Steven L. Smith, will perform spacewalks required for servicing of the HST.
