Here is situated a museum of Cosmonautics and Rocket Technology. In the early 1930s this room housed a gas dynamics laboratory under the supervision of the engineer Valentin Glushko which studied rocket science. Now visitors can view reconstructions of offices and work-stations of Soviet scientists, archival photos and documents, and unique rocket designs for liquid rocket engines and thrust engines of space rockets. Here you can also find models of the first space satellites, and the lander craft “Soyuz 16” which flew in space and returned to Earth in 1974.
