*Russian Navigation Computers in Stable Condition*

The Russian computers aboard the International Space Station are back in near normal, stable operation. Two of three channels of each computer are operating. A third channel is believed to be functioning well, but currently in standby.

The Mission Control Center in Moscow has restarted all Russian systems except the Elektron oxygen generation system, which has been powered but not yet started.

Flight controllers are planning to test Russian thrusters on Monday as they maneuver the station and Space Shuttle Atlantis to a water dump attitude.

The Russian navigation computers provide one method of backup attitude control and orbital altitude adjustments. The station’s control moment gyroscopes are the complex’s primary attitude control system. The shuttle’s propulsion system also provides a backup attitude control system for the complex.
