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.

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