The STS-67 Astro-2 mission, March 2-18,1995, was the second flight of the Astro observatory, a unique complement of three telescopes. During this record-setting 16-day mission, the crew conducted observations around the clock to study the far ultraviolet spectra of faint astronomical objects and the polarization of ultraviolet light coming from hot stars and distant galaxies. Mission duration was 399 hours and 9 minutes.
STS-81 (January 12-22, 1997) was a ten-day mission, the fifth to dock with Russia's Space Station Mir, and the second to exchange U.S. astronauts. The mission also carried the Spacehab double module providing additional middeck locker space for secondary experiments. In five days of docked operations more than three tons of food, water, experiment equipment and samples were moved back and forth between the two spacecraft. Following 160 orbits of the Earth the STS-81 mission concluded with a landing on Kennedy Space Center's Runway 33 ending a 3.9 million mile journey. Mission duration was 244 hours, 56 minutes.

In the course of five spacewalks, the crew installed new equipment on HST. This was the first flight of Columbia since the launch of Chandra in 1999 following refurbishment. In the first two spacewalks, two new solar arrays were installed, and the two old arrays stowed on the RAC carrier. The RWA-1R reaction wheel assembly on the MULE carrier replaced the faltering RWA-1 in the telescope. The third spacewalk was the most difficult, as HST was entirely powered down while astronauts replaced its power controller unit, not designed for on-orbit replacement. On the fourth spacewalk the astronauts removed the European FOC camera, aboard HST since launch in 1990, and replaced it with the new ACS (Advanced Camera for Surveys). They also installed the CASH wire harness, part of the aft shroud cooling system. On the final spacewalk, the astronauts installed the NCS (NICMOS cooling system) cryocooler in the aft shround and the associated NCS radiator on the telescope's exterior. The NICMOS infrared camera had been idle since its original thermal control system failed. With the removal of FOC, the COSTAR device (which deployed contact lenses for the original instruments) became obsolete, since the newer instruments made the corrections to the incorrect HST mirror internally.
