Cosmonaut Alexey Ovchinin of Expedition 60 trains on the tele-robotically operated rendezvous unit (TORU) two days before the arrival of the Progress 73 (73P) cargo ship. The 73P docked July 31 to the International Space Station's Zvezda service module just three hours and 19 minutes after launching from the Baikonur Cosmodrome in Kazakhstan. The TORU can be used to take over manual docking operations of an approaching Russian spaceship in the unlikely event of an emergency.
