Launch mass is 113881.9 (112563 in retrospective data). Sep mass of ET is 109965.3 kg. 3 EMUs carried. TCS. One HST-PFR in 13P and one on the FSS.
EVAs were carried out through the axial (longitudinal) hatch on the EAL. On the first EVA, the astronauts replaced HST's 6 gyros, the crucial mission task. Next, they fought with the valve covers on the NICMOS vents; they had planned to open the valves by hand and with a power ratchet tool, but in the end they had to go and get a pistol grip tool to remove the covers. The vents open, any remaining N2 will be vented by the time the new neon cooling system is installed on SM-3B. One of the old gyros wouldn't fit properly in the COPE at first, but eventually the crew managed to shove it in. The third task on EVA 1 was installation of Voltage Improvement Kits intended to prolong the life of the spacecraft's batteries. The walk was extended to allow the crew to install all six kits.
EVA-2 saw the installation of an Intel-486 based computer in the spacecraft.
During prep for EVA-3, Grunsfeld's suit had a problem, so he wore Foale's suit instead. On EVA-3, two bays were covered with the new outer blanket layers. There wasn't time to cover four more bays, so that was left for SM-3B.
