The Russian Progress 51 cargo spacecraft, now filled with trash, separated from the aft-end port of the Zvezda service module of the International Space Station on June 11, 2013. 

The Progress 51 will orbit Earth for a few days while controllers in Moscow perform engineering tests.

Then, the cargo craft will re-enter the atmosphere over the Pacific Ocean, and burn up.
