The Soviet Union created the Baikonur Cosmodrome in 1955 to serve as a test site for intercontinental ballistic missiles. A few years later it became the world's first spaceport with the launch of the historic Sputnik 1 and Vostok 1 missions. The sprawling cosmodrome was a mainstay of the Soviet space program.
After the breakup of the Soviet Union, Russia leased the spaceport from the government of Kazakhstan and currently has an agreement to use the facilities through the year 2050. Russia pays an annual lease fee of about $100 million. Neither country is particularly happy with the relationship; the Kazakh government feels like it is under-compensated, and the Russian government would like it to be in its own country, which is why it has moved in recent years to build a new launch site for most of its rockets in the Far East of Russia, at Vostochny.
Despite some of this uneasiness, however, the two governments have been working together on future space projects. For example, the main Russian space corporation, Roscosmos, has been developing a new medium-lift rocket that it anticipates launching from Baikonur. This is the Soyuz-5 vehicle, a three-stage rocket powered by RD-171 engines that will burn kerosene fuel. Russia is counting on this vehicle to replace its aging Proton-M rocket and be more cost-competitive with commercial rockets such as SpaceX's Falcon 9 booster.
Russia plans to launch the Soyuz-5 rocket from the "Baiterek" launch pad at Baikonur and intended to initiate preliminary construction work on the site in 2022. But those plans now face significant uncertainty.
Arresting assets
Earlier this month, a Kazakh news site, KZ24, reported that the Republic of Kazakhstan had seized the property of TsENKI, the Center for Utilization of Ground-based Space Infrastructure, in Kazakhstan. This firm, which is a subsidiary of Roscosmos, is responsible for launch pads and ground support equipment for the Russian space corporation. According to the report, which was translated for Ars by Rob Mitchell, TsENKI is barred from removing any assets or materials from Kazakhstan.
