STS-67 Endeavour (March 2–18, 1995) was the second flight of the ASTRO observatory, a unique complement of three telescopes.
During this 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-86 Atlantis (September 25 to October 6, 1997) was the seventh mission to rendezvous and dock with the Russian Space Station Mir.
Highlights included the exchange of U.S. crew members Mike Foale and David Wolf, a spacewalk by Scott Parazynski and Vladimir Titov to retrieve four experiments first deployed on Mir during the STS-76 docking mission, the transfer to Mir of 10,400 pounds of science and logistics, and the return of experiment hardware and results to Earth.
Mission duration was 169 orbits in 259 hours and 21 minutes.

STS-91 Discovery (June 2–12, 1998) was the 9th and final Shuttle-Mir docking mission and marked the conclusion of the joint U.S./Russian Phase I Program.
Mission duration was 235 hours, 54 minutes.

STS-114 Discovery (July 26 – August 9, 2005) was the first "Return to Flight" mission following the Space Shuttle Columbia disaster.
Highlights included the first in-flight repair to the orbiter during a spacewalk.
 Mission duration was 333 hours, 33 minutes.
