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.

After a night launch of Space Shuttle Atlantis, the Shuttle docked with Mir at 03:55 GMT on January 14. STS-81 transferred 2,715 kg of equipment to and from the Mir, the largest transfer of items to that date. During the docked phase, 640 kg of water, 515 kg of U.S. science equipment, 1,000 kg of Russian logistics, and 120 kg of miscellaneous material were transferred to Mir. Returned to Earth aboard Atlantis were 570 kg of U.S. science material, 405 kg of Russian logistics and 98 kg of miscellaneous material. At 02:16 GMT January 19, Atlantis separated from Mir after picking up John Blaha, who had arrived aboard STS-79 on September 19, 1996, and dropping off Jerry Linenger, who was to stay aboard Mir for over four months. The Shuttle backed off along the -RBAR (i.e. toward the Earth) to a distance of 140 m before beginning a flyaround at 02:31 GMT. Most of the flyaround was at a distance from Mir of 170 m. The first 'orbit' around Mir was complete at 03:15, and the second was completed at 04:02 GMT. Then the Orbiter fired its jets to drift away from the orbit of Mir. NASA's first Shuttle mission of 1997 came to a close with a landing at the Kennedy Space Center at 14:22 GMT on January 22 (after the first opportunity was waved off due to cloud cover at the Cape).
Trailing the Hubble Space Telescope by about 3,700 nautical miles and closing, the seven Discovery astronauts were awakened at 9:50 a.m. CST today to the sounds of Bachman-Turner Overdrive's "Taking Care of Business." The wake-up call from Mission Control began the crew's first full day in orbit. Discovery is closing on the telescope at a rate of about 340 nautical miles with each hour and a half long orbit of Earth. Additional Details: here....
Hubble Space Telescope (HST) servicing mission SM-3A, delayed repeatedly by technical problems with the shuttle fleet after the near-disastrous previous launch. Finally launched after the last possible day to avoid Y2K computer problems; one spacewalk was cancelled so that the shuttle could return by December 28. Hubble was in a 591 km x 610 km x 28.5 deg orbit at launch. After separation of the external tank ET-101 the Orbiter was in a 56 km x 587 km x 28.5 deg transfer orbit. The OMS 2 burn at 0134 UTC raised the orbit to 313 km x 582 km. The payload bay contained:
Discovery astronauts completed the two highest priority tasks of their Hubble Space Telescope servicing Wednesday with a space walk that was the second longest in history. Astronauts Steve Smith and John Grunsfeld installed six new gyroscopes and six Voltage/Temperature Improvement Kits in the telescope during their 8 hour, 15 minute spacewalk. Additional Details: here....
The Hubble Space Telescope received a new advanced computer Thursday from space-walking Discovery astronauts Mike Foale and Claude Nicollier. Their 8-hour, 10-minute space walk, the third longest in history, also saw replacement of a 550-pound fine guidance sensor. Additional Details: here....
Discovery astronauts completed their third and final space walk Friday evening, replacing a failed radio transmitter and installing a new solid state recorder. After the successful completion of those tasks, Lead Flight Director Linda Ham announced Friday evening that the STS-103 mission had met all criteria for complete success. Discovery astronauts are scheduled to release Hubble a little before 5 p.m. CST on Christmas Day. Additional Details: here....
The crew of Columbia was awakened for its first full day in space at 8:22 p.m. CST with the song "Blue Telescope" by John Hiatt. In its morning mail, the crew received news that mission managers are optimistic the full mission will go forward as planned in spite of low flow in a shuttle cooling line. Additional Details: here....
Hubble Servicing Mission 3B. STS-109 main engine cutoff came at 1130 UTC with Columbia in a 55 x 574 km x 28.5 deg transfer orbit. The OMS-2 burn at about 1207 UTC raised perigee to about 195 km. There was a problem with a freon cooling loop on the Orbiter, but it wasn't quite bad enough to affect the mission. The Hubble Space Telescope closed its aperture door on March 2 in preparation for the rendezvous. Columbia got within 100m of HST by 0852 UTC on March 3 and grappled it with the RMS at 0931 UTC. HST was berthed on the FSS in Columbia's payload bay by 1032 UTC.
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.

Spacewalkers Grunsfeld and Rick Linnehan will step out into space for the first time during this mission at about 12:30 a.m. tomorrow morning. Additional Details: here....
Rested and ready for another day of spacewalking, the crew of the space shuttle Columbia was awakened at 7:53 p.m. by the children's song "Floating in the Bathtub," by Tonya Evetts Weimer. It was played for Jim Newman who is to step out into space for the second spacewalk of this mission at about 12:30 a.m. Tuesday. Additional Details: here....
The Hubble Space Telescope received a new "heart" today during a 6 hour, 48 minute spacewalk by astronauts John Grunsfeld and Rick Linnehan. The two installed a new Power Control Unit (PCU), replacing the original unit launched with the telescope in April 1990. The PCU serves as Hubble's central power switching station by distributing electricity to all systems, scientific instruments and the Nickel Hydrogen batteries. Additional Details: here....
The crew of the space shuttle Columbia will give Hubble a way to open one of its slumbering eyes during the fifth and final scheduled spacewalk of this mission. An experimental cooling system will be installed on a camera that has been dormant since 1999 in hopes of bringing it back to life. Additional Details: here....
TThe crew of the space shuttle Columbia completed the last of its five ambitious spacewalks this morning with the successful installation of an experimental cooling system for Hubble's Near-Infrared Camera and Multi-Object Spectrometer (NICMOS). The NICMOS has been dormant since January 1999 when its original coolant ran out. Additional Details: here....
The EVA ran from 0841 to 1606 UTC. The astronauts installed the NICMOS cooling system (NCS). During preparations for EVA-3, a problem with a valve on Grunsfeld's suit caused it to leak water, and Grunsfeld switched to Newman's suit. For each of EVA-3,4,5 the appropriate size legs and arms were replaced on the same basic HUT (Hard Upper Torso)/PLSS (Primary Life Support System) combination.
After five days of successful spacewalks to rejuvenate the Hubble Space Telescope, the crew of Columbia will enjoy a Sunday off. The crew was awakened at 8:50 p.m. CST Saturday by "Fly Me to the Moon" by Frank Sinatra. The song was played for Commander Scott "Scooter" Altman. Additional Details: here....
The space shuttle Columbia landed at Kennedy Space Center early Tuesday after a 10-day, 22-hour and 10-minute mission to upgrade the Hubble Space Telescope.
