*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
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.
