Progress

Progress is a Soviet and later Russian uncrewed cargo spacecraft used to resupply space stations in orbit, derived from the crewed Soyuz spacecraft design but modified to carry fuel, supplies and equipment instead of a crew. First flown in 1978 to resupply the Salyut 6 space station, the Progress series has since supplied the Mir space station and the International Space Station, burning up in the atmosphere at the end of each mission along with a station accumulated waste. Roscosmos has continued launching new Progress vehicles to the International Space Station as its primary uncrewed Russian resupply vehicle.
