Soyuz docking issue during ISS arrival
When the manned Soyuz rendezvoused and docked with ISS yesterday, there was a problem with the automatic docking system, requiring the astronauts to take over and manually dock the spacecraft.
Initial reports suggested the failure was with the radar system having a conflict with the communications systems on the berthed Cygnus capsule. The link above instead claims the failure was caused by a malfunction in one of the Soyuz attitude thrusters. The former would be annoying but less of a concern than the latter. A thruster malfunction is somewhat rare, and would be another indication of the serious quality control problems in the Russian aerospace industry.
