Berthing latches on the FSS

S103-E-5170 (21 December 1999) --- This closeup electronic still camera's view shows the lower portion of the Hubble Space Telescope (HST) as the giant observatory is berthed in Discovery's cargo bay. The gold-shielded apparatus at the bottom of the frame is the flight support system (FSS), a turntable device similar to a "Lazy Susan" because of its ability to rotate and tilt to assist the upcoming servicing tasks. The image was recorded at 19:49:22 GMT, Dec. 21, 1999 but was not
able to be downlinked by the astronauts until late on the following day.
