Three landmark orbital missions left Earth from the Baikonur cosmodrome, across a span of 62 years.

Sputnik, the first artificial satellite, lifted off from the site on 4 October 1957.[^3] Four weeks later, an R-7 rocket carried the dog Laika into orbit from the same launch region.[^2] On 13 July 2019, the Mikhail Pavlinsky ART-XC X-ray telescope launched from Baikonur aboard a Proton rocket.[^1]

No additional launches from the site are confirmed in the filed records.
