The launch of this tanker has been delayed for 4 or 5 days due to serious
problems aboard the MIR-space station.
MIR: Insufficient power supply to one of the Modules caused a malfunction
in the attitude control system of the complex. The huge gyroscopes (called
gyrodynes) stopped, and the TsVM-1 (Main Computer) and the SUD (control of
movements) switched themselves off.
Now the complex is in the so called ‚”free drift”. The BUPO, the analogue
back-up system, needed to achieve the necessary stable attitude for the
activation of the digital attitude control system, does not function at
this point. TsUP will do all what is possible to activate all systems today.
Telemetry: Today (18.01) during the pass of the MIR-station in orbit 85308, I
could monitor the telemetry transmitters on 638.085.7 and 637.829.0 mc
between 10.28.29 and 10.30.10UTC. The signals were very weak. I did not hear
the telemetry transmissions in the 166 and 165 mc bands.
Consequencies: The Russians have to do all what is possible to cope with this
problem. In my opinion a manned maintenance mission inevitable. This crew
will have to take care for a thorough overhaul of all crucial systems. I
would not be surprised if we get an official announcement about such a
mission today or tomorrow.
