View of the Hubble Space Telescope HST docked on the Flight Support System FSS located in the aft end of the Discovery's payload bay PLB. The HST is turned so that the -V3 plane is facing the orbiters crew compartment. Visible in this view are the three fixed-head star tracker FHST and the Wide Field/Planetary Camera WF/PC. Also visible are the lower parts of the HST solar arrays. An Earth limb forms part of the background. Reflections from the aft flight deck windows are also present.
