How does a disposable cargo ship sustain the space station?
The uncrewed Roscosmos spacecraft docked with the space-facing port of the station’s Poisk module at 9:44 a.m. EDT, carrying about three tons of food, fuel and supplies for Expedition 75 [6]. It launched aboard a Soyuz rocket from Baikonur Cosmodrome on September 16 and is scheduled to remain attached for about five months [6].
Why it matters
Progress vehicles serve two functions in the station’s logistics chain: they deliver consumables and later remove trash through planned destructive atmospheric re-entry, unlike SpaceX’s reusable Dragon cargo capsule [6][7].
Key insights
- The spacecraft’s trip from launch to docking lasted about three days [6][7].
- Progress 96 will be loaded with waste before it departs the station and burns up in Earth’s atmosphere [6][7].
- Progress, HTV-X and Cygnus cargo vehicles are designed for destructive disposal, while Dragon is the current cargo fleet’s reusable freighter [7].
