er. It underwent tests after being rebooted earlier and it looks like everything is working fine,“ a spokeswoman said by telephone from Mission Control at Korolyov outside Moscow. The computer, which controls the station‘s alignment, failed on Saturday, leaving Mir adrift in orbit but in no immediate danger. Attempts to restart the troublesome computer on Sunday were unsuccessful. It was replaced with a spare one which failed to reboot properly on Sunday night. Now the cosmonauts will try to re-establish alignment with the help of electrically powered gyroscopic devices and Mir‘s engines. Normal alignment has to be restored for the U.S. space shuttle‘s last visit to the Russian station to go ahead as planned. NASA‘s flight rules require Mir to have a working control system before the space shuttle can safely dock. The shuttle is due to pick up Andrew Thomas, the last of seven U.S. astronauts to serve on Mir. Mission managers were to meet on Monday to decide whether to proceed with the shuttle launch, scheduled for about 2210 GMT on Tuesday.
