Leninsk test site got its name after the town of Leninsk, which was renamed Baikonur by former Russian President Boris Yeltsin in the mid-1990s. Baikonur Cosmodrome is the world's largest and oldest working space facility.[2] Apart from dozens of launch pads, it includes five tracking control centers, nine tracking stations, and a 1,500km rocket test range.[1] Russia has rented the facility from Kazakhstan since 1993.[2]
