Mir Status 19 October 1997

NASA 6 Status Date: Sunday, October 19, 1997// MD 75/24

Mir Station System/Subsystem Activities

The Progress vestibule was successfully depressurized today. The station was commanded to free drift at DMT 11:37 this morning, and the crew then removed the Progress clamps and closed the Kvant-1 hatch. The depress was started at 13:05, and by the end of the comm pass the pressure had dropped to 37 mm. The valve was closed and the station returned to solar inertial attitude control at 13:41.

In further preparations for the IVA, the crew disconnected the cables for the Omega angular rate sensor in Kristall, and ORT-1 was enabled as the primary sensor, with ORT-2 in hot standby mode. They also disconnected the cables for the Kvant-2 Elektron, which receives power from Kristall. They shut down the Kvant-1 Elektron without purging after the 13:00 comm pass.

Power Down of OPM and CHAPAT


Dave reported yesterday that he used a pH strip from the Water kit and measured the liquid in the BTR. He said it registered 5.5 which is the same as other condensate measured in the station.

Experiment Operations -- Physical Fitness Assessment: Dave reported that the HRM procedures are needlessly complicated and iterative.

Earth Obs: Dave reported that he has been receiving the list of available sites and has had time to accomplish some observations.


David reported that he is not fatigued prior to the IVA tomorrow, iIim at 100%, and ready to go.i
