The Progress 47 successfully completed the dockingtest on its second try, after a first attempt on July 23 was prematurely aborted due to a technical glitch.
The scheduled trip comes just a little over four months after the project successfully completed a dockingtest by the unmanned private spacecraft with the International Space Station.
Before leaving the space station, the Progress 47 spacecraft conducted a test of an upgraded docking system that Russia intends to use on future unmanned Progress and manned Soyuz vehicles.
