Progress is a Russian expendable cargo spacecraft. Originally developed for the Soviet space program and derived from the crewed Soyuz spacecraft, Progress has been instrumental in maintaining long-duration space missions by providing consumables like food, water, and air, as well as maintenance equipment. Since its maiden flight in 1978, Progress has supported various space stations, including Salyut 6, Salyut 7, and Mir, and remains a key resupply vehicle for the International Space Station (ISS).
