Baikonur, built in Kazakhstan in the 1950s, was first leased by Russia from Kazakhstan under an agreement signed in 1994 after the collapse of the Soviet Union. Russian officials have repeatedly said Russia will continue to use the Baikonur launch site until at least 2050.
Alexander Mezentsev, the mayor of Baikonur, told a news conference that Russia launched a total of 21 carrier rockets from the site in 2007.
At present, the two countries are working to build a space complex at Baikonur, Baiterek, to launch Angara carrier rockets capable of delivering 26 metric tons of payload into low-Earth orbits. The project is being implemented on a parity basis and enjoys tax, customs and other privileges.
Kazakhstan and Russia have reportedly each allocated $223 million for the construction of the Baiterek launch site under a 2004 agreement.
"We have prepared the documentation and developed technical requirements [for the project], and all that's left is to start construction," Mezentsev said without revealing any specific details.
