A portion of the International Space Station's Russian segment is pictured before the Progress 69 cargo craft undocked from the aft end of the Zvezda service module. Also attached to the forward end of Zvezda are the Poisk and Pirs modules. The Poisk module hosts the docked Soyuz MS-08 crew ship that brought three Expedition 55/56 crew members to the station in March of 2018. The Pirs docking compartment hosts the Progress 70 resupply ship which delivered several tons of food, fuel and supplies to the Expedition 56 crew in July of 2018.
