KENNEDY SPACE CENTER, FLA. - Workers in KSC's Vertical Processing Facility make final prelaunch prepartions to various payload elements that are part of the second Hubble Space Telescope (HST) servicing mission, STS-82. Liftoff is targeted Feb. 11 aboard Discovery with a crew of seven.

STS072-393-008 (17 Jan. 1996) --- Astronaut Leroy Chiao gives a thumbs up signal, marking the success of his second extravehicular activity (EVA) in three days. Chiao was joined by astronaut Winston E. Scott on this EVA.

STS072-722-041 (17 Jan. 1996) --- Astronaut Winston E. Scott traverses the portside of the Space Shuttle Endeavour's cargo bay during the second of two Extravehicular Activities (EVA) to demonstrate space station assembly techniques. A 30mm lens on a 70mm handheld camera gives a "fish-eye" effect to the scene. Both the Japanese Space Flyer Unit (SFU) and the Office of Aeronautics and Space Technology (OAST) Flyer satellite are in their stowed positions. TV cameras on the Remote Manipulator System (RMS) provided live coverage of the activity.

KENNEDY SPACE CENTER, FLA. - At the KSC Launch Pad 39A, two members of the payload closeout crew check equipment as the doors are just about ready to be closed. The Payload inside the bay of Discovery, the orbiter for the STS-82 mission, is ready for the launch of the second Hubble Space Telescope service mission. The payload consists of the Near Infrared Camera and Multi-Object Spectrometer (NICMOS) that will be installed, Fine Guidance Sensor #1 (FGS-1), and the Space Telescope Imaging Spectrograph (STIS) to be installed. The STS-82 will launch with a crew of seven at 3:54 a.m. EST, Feb. 11, 1997. The launch window is 65 minutes in duration. The Mission Commander for STS-82 is Ken Bowersox. The purpose of the mission is to upgrade the scientific capabilities, service or replace aging components on the Telescope and provide a reboost to the optimum altitude.

KENNEDY SPACE CENTER, FLA. - Workers in the Payload Changeout Room (PCR) at Launch Pad 39A are preparing to close the payload doors for flight on the Space Shuttle Atlantis, targeted for liftoff on Mission STS-79 around Sept. 12. The SPACEHAB Double Module located in the aft area of the payload bay is filled with supplies and other items slated for transfer to the Russian Space Station Mir. STS-79 marks the second flight of a SPACEHAB in support of the Shuttle-Mir dockings, and the first flight of the double-module configuration. The SPACEHAB is connected by tunnel to the Orbiter Docking System (ODS), with the Androgynous Peripheral Docking System (APDS) clearly visible on top of the ODS. The APDS provides the docking interface for the linkup with Mir, while the ODS provides a passageway from the orbiter to the Russian space station and the SPACEHAB.

KENNEDY SPACE CENTER, FLA. - The launch tower on Launch Complex 17-A, Cape Canaveral Air Force Station, clears the Boeing Delta II rocket and its Mars Exploration Rover (MER-A) payload in preparation for a second attempt at launch. The first attempt on June 8, 2003, was scrubbed due to bad weather in the vicinity. MER-A is the first of two rovers being launched to Mars. When the two rovers arrive at Mars in 2004, they will bounce to airbag-cushioned landings at sites offering a balance of favorable conditions for safe landings and interesting science. The rovers see sharper images, can explore farther and examine rocks better than anything that has ever landed on Mars. The designated site for MER-A mission is Gusev Crater, which appears to have been a crater lake. The second rover, MER-B, is scheduled to launch June 25.
