A Russian cargo ship carrying a back-up computer and other crucial supplies docked with the Mir space station Wednesday -- one day later than planned.
The Progress M-36 docked a few minutes ahead of schedule. It will take the crew about an hour to make sure the seal is tight between the cargo ship and Mir before opening the hatch.
The docking was delayed because an old garbage-filled supply ship that occupied the docking port failed to detach on command Monday. The crew of the space station neglected to properly unhook one of 16 latches holding the ship to the port. After the latch was released, the old cargo ship disengaged smoothly.
The Progress M-36, which was launched Sunday and had been waiting in orbit for the docking, is carrying two tons of equipment and supplies.
The space shuttle Atlantis, which left Mir last week, delivered a replacement computer and other important equipment, including sealant for holes caused when a cargo ship slammed into Mir's Spektr module during a practice docking in June.
