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.
On STS-80 (November 19 to December 7, 1996), the crew aboard Space Shuttle Columbia deployed
and retrieved the Wake Shield Facility (WSF) and the Orbiting Retrievable Far and Extreme Ultraviolet
Spectrometer (ORFEUS) satellites. The free-flying WSF created a super vacuum in its wake in
which to grow thin film wafers for use in semiconductors and the electronics industry. The ORFEUS
instruments, mounted on the reusable Shuttle Pallet Satellite, studied the origin and makeup
of stars. In completing this mission he logged a record 278 earth orbits, traveled over 7 million
miles in 17 days, 15 hours, 53 minutes.
