On May 10, 2010 the Progress M-04M unmanned supply spacecraft was undocked from the International space station at 11:15 UTC.
The vehicle has been attached to the docking port on the Zvezda module since February 3, 2010.
After separation, the Progress will continue flying autonomously for about 1.5 months. Prior to the Progress deorbiting, a series of geophysical experiments is to be carried out.
In a couple of days, the Soyuz TMA-17 manned spacecraft is to be redocked from the Zarya module to the Zvezda docking port vacated by the Progress.
