Russian Docking System Tested Aboard the ISS.

A Russian ISS Progress 62 cargo ship automatically undocked from the International Space Station July 1, moved to a distance of about 600 feet away from the complex, then re-approached and re-docked a short time later under the manual control of Expedition 48 cosmonauts Alexey Ovchinin and Oleg Skripochka of Roscosmos. The cosmonauts were testing an upgraded backup rendezvous system of the spacecraft, which cosmonauts can use to take over the manual control of an approaching unpiloted craft for docking in the unlikely event a problem.
