A full-scale mockup of Russia's Space Station serves as one of the several training aids for cosmonaut flights aboard the orbiting laboratory. The core module - called Mir, for world of space - was launched in February 1986 and now serves as the main living quarters for crews. The mockup is located at the Gagarin Cosmonaut Training Center in Star City, Russia. At the time this photo was taken, NASA astronauts Norman E. Thagard and Bonnie J. Dunbar were in Russia for training.
