From NASA bio here:
STS-61 was the first Hubble Space Telescope (HST) servicing and repair mission. Following a night launch from Kennedy Space Center on December 2, 1993, the Endeavour rendezvoused with and captured the HST. During this 11-day flight, the HST was restored to its full capabilities through the work of two pairs of astronauts during a record 5 spacewalks. Dr. Musgrave performed 3 of these spacewalks. After having travelled 4,433,772 miles in 163 orbits of the Earth, Endeavour returned to a night landing in Florida on December 13, 1993. Mission duration was 10 days, 19 hours, 59 minutes.
Story said it took 22 turns to get the bay doors open on the Hubble. The STS-125 team picked his brain before the mission to get information on the first servicing mission.
