1993-075A
The first HST Servicing Mission was launched on 1993 Dec 2. The astronauts reported tally-ho (visual sighting of the target) at 0746 on Dec 4. The EVA-2 repress was halted at 0.8 psi for 4 minutes and depressurized again to clear KT's ears. A slow repress began at 6h45m into the EVA and by 1017 the pressure reached 4.5psi, 6h 52m into the EVA (the official EVA time was 6h36m). Cabin pressure was reached at 1022.
