An uncrewed Roscosmos Progress 85 spacecraft arrived at the International Space Station’s aft port of the Zvezda service module at 11:45 p.m. EDT. The spacecraft launched on a Soyuz rocket at 9:08 p.m. EDT on Tuesday, August 22 (6:08 a.m. Baikonur time on August 23) from the Baikonur Cosmodrome in Kazakhstan.
Progress is delivering almost three tons of food, fuel, and supplies to the International Space Station for the Expedition 69 crew.
The spacecraft will remain at the orbiting laboratory for approximately six months, then undock for a destructive but safe re-entry into Earth’s atmosphere to dispose of trash loaded by the crew.
Roscosmos Progress spacecraft are a series of uncrewed cargo spacecraft developed by the Soviet Union (and later operated by its successor state, Russia) to supply the space station programs with which the country was involved. They were specifically designed to deliver supplies to the Salyut and later the Mir space stations, and now serve the International Space Station.
These spacecraft have played a crucial role in supporting long-duration human spaceflight by ensuring that space stations remain stocked with the necessary supplies and fuel.
