On September 21 the Russian “Progress M-67” unmanned supply spacecraft successfully undocked from the International Space Station.

Progress M-67, the last Russian cargo spacecraft with an analogue control system, arrived at the orbital station on July 29, bringing 2.5 tons of supplies to the ISS, including fuel, water and various equipment.

The spacecraft will now be used as an orbital laboratory to conduct a series of geophysical experiments under the Plasma-Progress program before reentering the Earth's atmosphere on September 27 and plunging into a "spaceship cemetery" in the southern Pacific.

Progress-series freighters have been the backbone of the Russian space cargo fleet for decades. In addition to their main mission as cargo spacecraft, they are used to adjust the ISS orbit and conduct scientific experiments.
