Baikonur Cosmodrome has a small museum, next to two small cottages, once residences of the rocket engineer Sergei Korolev and the first cosmonaut, Yuri Gagarin. Both cottages are part of the museum complex and have been preserved. The museum is home to a collection of space artifacts. A restored test artifact from the Soviet Buran programme sits next to the museum entrance. The vehicle that flew a single orbital test mission in 1988 was destroyed in a hangar collapse in 2002; For a complete list of Buran artifacts, see Buran (spacecraft).
