}} Gagarin's Start〔"As Suffredini spoke, a Soyuz TMA-5 spacecraft was being hoisted onto Russia's Baikonur launch pad, named "Gagarin's Start" after the first man in space. ", http://www.chinadaily.com.cn/english/doc/2004-10/13/content_381791.htm , China Daily, 2004-10-13 on Soyuz TMA-5 launch〕 ((ロシア語:Гагаринский старт), ''Gagarinskij start'') is a launch site at Baikonur Cosmodrome in Kazakhstan, used for the Soviet space program and now managed by the Russian Federal Space Agency. The launchpad for the world's first human spaceflight made by Yuri Gagarin on Vostok 1 in 1961, the site was referred to as Site No.1 (, ''Ploshchadka No. 1'') as the first one of its kind. It is also sometimes referred to as ''NIIP-5 LC1'', ''Baikonur LC1'' or ''GIK-5 LC1''. On 17 March 1954 the Council of Ministers ordered several ministries to select a site for a proving ground to test the R-7 rocket by 1 January 1955. A special reconnaissance commission considered several possible geographic regions and selected Tyuratam in the Kazakh SSR. This selection was approved on 12 February 1955 by the Council of Ministers, with a completion of construction targeted for 1958.〔(Origin of the test range in Tyuratam ) at Russianspaceweb.com〕 Work on the construction of Site No.1 began on 20 July 1955 by military engineers. Day and night more than 60 powerful trucks worked at the site; of earth were excavated and removed per day, with the total volume estimated to be . During winter explosives were widely utilized. By the end of October 1956 all primary building and installation of infrastructure for R-7 tests was completed. The Installation and Testing Building (, ''Montazhno-ispytatel'nyj korpus'') named "Site No.2" was built and a special railway completed from there to Site No.1 where the launch pad for the rocket was located.〔 (Creation and Launch of the First Earth's Satellite ) by V.Poroshkov〕 By April 1957 all remaining work was completed and the site was ready for launches. First intended for the R-7 ballistic missile program, the first ICBM was launched from Site No.1 on 21 August 1957. On 4 October 1957 the pad was used to launch the world's first artificial satellite, Sputnik 1. Manned spaceflights launched from the site include Yuri Gagarin's flight, Valentina Tereshkova's flight, and numerous other human spaceflight missions, including all Soviet and Russian manned spaceflights to Mir. The pad was also used to launch Luna program spacecraft, Mars probe program spacecraft, Venera program spacecraft, many Cosmos satellites and others.〔(Baikonur LC1 )〕 From 1957 through 1966 the site hosted ready-to-launch strategic nuclear ICBMs in addition to spacecraft launches;〔 by the 2000s there were more than 400 launches from the site.〔(Gagarin's pad )〕 The 500th launch from this site was of Soyuz_TMA-18M on 2nd September 2015. ==Gallery== File:Soyuz TMA-16 Lifts Off.jpg|Soyuz TMA-16 launches from the Gagarin's Start on September 30, 2009, on its way to the International Space Station.
