Space Race participant Soviet Union
Legacy
After the end of the Cold War in 1991, the assets of the USSR's space program passed mainly to Russia. Since then, the United States and Russia have cooperated in space with the Shuttle-Mir Program, and the International Space Station (ISS).
The Russians continue to use their R-7 rocket family as their orbital workhorse to launch the Soyuz crewed spacecraft and its  Progress derivative uncrewed cargo craft as shuttles to the ISS. After the 2011 retirement of the Space Shuttle, American crews were dependent on the R-7–Soyuz to reach the ISS, until the 2020 first flight of the US Crew Dragon Commercial Crew Development vehicle.
