Period: 90.00 min. OV-102 Columbia was launched on a microgravity science mission. Spartan 201 was released a day late on November 21. However the satellite did not start its automatic orientation maneuver because the crew failed to send it the correct commands prior to release.

    Spartan was recaptured by hand, during a spacewalk by Takao Doi and Winston Scott on November 25. Tests of space station tools went well, but the free-flying Sprint camera subsatellite was not deployed due to lack of time.

    NASA decided not to redeploy Spartan on this mission. During an EVA on Dec 3, Doi and Scott carried out more tests of the Space Station crane. They also deployed the AERCam/Sprint 'football' remote-controlled camera for a free flight in the payload bay.

    Columbia landed on December 5, with a deorbit burn at 11:21 GMT. Touchdown was at 12:20 GMT at Kennedy Space Center.

Flight: ISS EO-16; ISS EO-16-2; ISS EO-16-3; STS-122; STS-123. Upon wakeup, FE--2 Eyharts performed the last sampling of his first session with the NASA/JSC experiment NUTRITION w/Repository, collecting a final urine sample for storage in the MELFI (Minus-Eighty Laboratory Freezer for ISS).

    The sampling kit was then stowed away. Leo's next NUTRITION/Repository activity will be his Flight Day 30 (FD30) session. (The current NUTRITION project is the most comprehensive in-flight study done by NASA to date of human physiologic changes during long-duration space flight. It includes measures of bone metabolism, oxidative damage, nutritional assessments, and hormonal changes, expanding the previous Clinical Nutritional Assessment profile (MR016L) testing in three ways: Addition of in-flight blood & urine collection (made possible by MELFI), normative markers of nutritional assessment, and a return session plus 30-day (R+30) session to allow evaluation of post-flight nutrition and implications for rehabilitation.)

Flight: ISS EO-16; ISS EO-16-1; ISS EO-16-2; ISS EO-16-3; STS-122; STS-123. For the purpose of testing the main TORU (Teleoperator Control System) receiver on Progress M-63/28P, FE-1 Malenchenko and CDR Whitson worked with ground specialists via VHF on DO3 (Daily Orbit 3) in the standard vehicle-to-vehicle TORU checkout between the Service Module (SM) and the docked Progress 28P.

    Progress thrusters (DPO) were inhibited and not involved. (Crew activities focused on TORU activation, inputting commands via the RUO Rotational Hand Controller and close-out ops. TORU lets an SM-based crewmember perform the approach and docking of automated Progress vehicles in case of failure of the automated KURS system. Receiving a video image of the approaching ISS, as seen from a Progress-mounted docking television camera ('Klest'), on a color monitor ('Simvol-Ts', i.e. 'symbol center') which also displays an overlay of rendezvous data from the onboard digital computer, the crewmember steers the Progress to mechanical contact by means of two hand controllers, one for rotation (RUO), the other for translation (RUD), on adjustable armrests. The controller-generated commands are transmitted from the SM's TORU control panel to the Progress via VHF radio. In addition to the Simvol-Ts color monitor, range, range rate (approach velocity) and relative angular position data are displayed on the 'Klest-M' video monitor (VKU) which starts picking up signals from Progress when it is still approximately 7 km away. TORU is monitored in real time from TsUP over Russian ground sites (RGS) and via Ku-band from Houston, but its control cannot be taken over from the ground.) Additional Details: here....

Endeavour's main task was delivery of the Canadian Dextre robotic manipulator (fitted to the end of the Canadarm-2 robotic arm already installed on the station) and the Japanese Kibo ELM-PS Experiment Logistics Module - Pressurized. It also brought astronaut Reisman to the station, replacing Eyharts on the long-duration crew. The orbiter was placed in an initial 58 km x 220 km orbit at main engine shutdown, adjusted by the OMS-2 firing 38 minutes later to a 220 km x 233 km chase orbit. On 13 March the shuttle docked with the PMA-2 port of the International Space Station at 03:49 GMT. Mission accomplished, Endeavour undocked at 00:25 GMT on March 25, completed the customary ISS flyaround at 01:36 GMT, deorbited at 23:33 GMT the next day, and landed at 00:39 GMT at Kennedy Space Center.

    More good news!

    SPDM Dextre was checked out and is working nominally with both arms. (The waist-up-only robot from Canada arrived in space in nine separate pieces that are being assembled in the current spacewalks. Each of the two arms has seven joints; in addition, SPDM (Special Purpose Dexterous Manipulator) Dextre can pivot at the 'waist'. Its grippers (hands) have built-in socket wrenches, cameras & lights. Only one arm is movable at a time, to keep the robot stable and avoid a two-arm collision. Dextre can be attached to MT (Mobile Transporter) to translate along the stations rail tracks, or alternately to the SSRMS (Space Station Remote Manipulator System) to swing to places where the railcart can't go.

    Three more major mission steps were accomplished:

    SPDM (Special Purpose Dexterous Manipulator) 'Dextre', with repositioned arms, was successfully stowed on the U.S. Lab PDGF (Power & Data Grapple Fixture) (and is looking very cool);
    SLP (Spacelab Pallet) was returned to the Shuttle PLB (Payload Bay) for re-berthing; and
    SSRMS (Space Station Remote Manipulator System) was 'walked off' the Node-2 PDGF onto MT/MBS (Mobile Transporter/Mobile Base System) PDGF-3 and maneuvered into position for today's MT translation from Worksite 6 (WS6) to WS4.
    (During commanding of the SPDM's body ('waist') roll joint to stowage mode, it rotated in the opposite direction than expected, due to a sign mistake (polarity inversion, i.e., a plus-sign instead of a minus-sign) in the DMCS (Dexterous Manipulator Control Software) configuration file. Flight Controllers worked around this in real time, and the crew was able to maneuver the SPDM LEE (Latching End Effector) onto the LAB PDGF without further ado. Work is underway at CSA/MDA to write a corrective software patch.) Additional Details: here....

    EVA-4 was completed successfully by Bob Behnken & Mike Foreman in 6h 24m, accomplishing most of its objectives.
    During the spacewalk, Behnken (EV1) & Foreman (EV2) -

    Demonstrated an on-orbit heat shield repair technique using the T-RAD (Tile Repair Ablator Dispenser) to demonstrate an Orbiter tile repair DTO (Development Test Objective) in space. (The spacewalkers tested STA-54, a pink putty-like material consisting of two compounds that are mixed together in a pressure-driven applicator gun just before they exit the nozzle. With Foreman working the applicator, the test was completed nominally, and the test samples were stowed in the TSA (Tool Stowage Assembly in the Orbiter PLB (Payload Bay) for return and analysis; results looked good);
    Removed RPCM (Remote Power Controller Module) S02B-D on the S0 truss and replaced it with a new unit. (Since the RPCM controls CMG-2 (Control Moment Gyroscope #2), circuitry had to be powered down and the CMG-2 removed from the steering law beforehand. After the successful R&R, the spacewalkers attempted several times to reconfigure the Z1 patch panel, a pre-requisite for powering the new RPCM, but were unable to do so due to tough-to-reach connectors which could not be unmated. The patch panel reconfiguration currently remains incomplete, but there are no impacts to current operations);
