With more than 40 percent of their mission completed, Columbia’s seven astronauts are continuing around-the-clock science investigations in the Spacelab module, focusing on how various materials and liquids change and behave in weightlessness.
After a brief handover with their blue team counterparts just after midnight, the red team members -- Commander Jim Halsell, Pilot Susan Still, Mission Specialist Don Thomas and Payload Specialist Greg Linteris -- took over responsibility for the management of science operations aboard the Shuttle.
After completing his daily exercise period, Halsell conducted status checks and performed video documentation of some of the Microgravity Science Laboratory experiments and activities in the Spacelab. The first part of Pilot Susan Still’s day involved monitoring orbiter systems and working an in-flight maintenance procedure with the Shuttle Amateur Radio Experiment (SAREX). Following a daily lab planning session, Thomas continued experiments in the Glovebox unit and Linteris worked with the Combustion Module.
After they take a lunch break, Thomas and Linteris will continue the same science efforts with the addition of work with the Large Isothermal Furnace. Halsell and Still will continue watching over Shuttle systems, performing some air monitoring checks as well. They also will conduct some communication sessions with the SAREX unit.
A possible SAREX communication session between the crew aboard Columbia and astronaut Mike Foale aboard the Mir space station may take place just before 2 p.m. CDT at 7/00:57 MET. If it happens, the linkup between the two spacecraft will be accomplished by routing Foale through ham radio operators at the Johnson Space Center and into mission control. The Shuttle and Mir will not be passing close to one another for this communications opportunity. The conversation between Mir and Columbia will depend on Foale’s schedule.
The STS-94 Blue team, Payload Commander Janice Voss, Mission Specialist Mike Gernhardt and Payload Specialist Roger Crouch, will be awakened just after 11 a.m. CDT and will take over responsibility for science and orbiter operations shortly after 1 p.m.
The next STS-94 status report will be issued at about 6 p.m.
