An unmanned module docked with the Mir space station today, bringing the cosmonauts a "space motorcycle" that will allow them to work outside the station in greater safety and comfort.
Problems with a guidance system had prevented the 40-ton Kvant 2 module from docking as scheduled on Saturday. The Tass dispatch announcing today's docking did not say how that difficulty had been overcome.
The "space motorcycle" looks like a floating armchair and was designed for use in repairing satellites and rescuing cosmonauts in distress.
Cosmonauts Alexander S. Viktorenko, 42, and Alexander A. Serebrov, 45, the latest Mir crew, have been aboard the space station for three months.
