other meanings

Baikonur (, Baiqoñyr, ; Байконур, ), formerly known as Leninsk, is a city in Kazakhstan on the northern bank of the Syr Darya river. It is currently leased and administered by the Russian Federation as an enclave until 2050. It was constructed to service the Baikonur Cosmodrome and was officially renamed Baikonur by Russian president Boris Yeltsin on December 20, 1995. During the Soviet period, it was sometimes referred to as Zvezdograd (Звездоград), Russian for Star City. The rented area is an ellipse measuring east to west by north to south, with the cosmodrome situated at the area's centre. Foreign visitors and tourists can visit the cosmodrome and city but need to obtain a specific permit from Roscosmos.

The original Baikonur (Kazakh for "wealthy brown", i. e. "fertile land with many herbs") is a mining town 320 kilometres northeast of the present location, near Dzhezkazgan in Kazakhstan's Karagandy Region. Starting with Vostok 1 in April 1961, the launch site was given this name to cause confusion and keep the location secret. (The original Baikonur's residents took advantage of the confusion by ordering and receiving many scarce materials before government officials discovered the deception.) Baikonur's railway station predates the base and retains the old name of Tyuratam. This was the original Soviet railway station (railhead) on the Moscow to Tashkent Railway that the Cosmodrome was initially named after. The fortunes of the city have varied according to those of the Soviet or Russian space program and its Baikonur Cosmodrome. Due to the city's military and scientific significance, it was closed off by Soviet authorities. It did not appear on maps available to the general public during the Soviet period prior to perestroika. The Soviet government established the Nauchno Issledovatel'skii Ispytatel'nyi Poligon N.5 (NIIIP 5), or Scientific Research Test Range N.5 by its decree of 12 February 1955. The U 2 high altitude reconnaissance plane found and photographed the Tyuratam missile test range (cosmodrome Baikonur) for the first time on 5 August 1957. The town has unique ties with space, and hence the history of the rocket building and space binds all the sights in the area and the cosmodrome. However, there are only a few exceptions: old locomotive, an Orthodox Church and a new mosque. The city administratively belongs to the Odintsovsky District of Moscow Oblast.

South of city center, near the Syr Darya River there is a large park with several sports and amusement facilities. Among these is a ferris wheel, which is no longer in use. The park is located at coordinates .
