Soviet Deep Space Network
{{Short description|Network of space communication facilities}}
The Soviet Deep Space Network (or Russian Deep Space Network) is a network of large antennas and communication facilities that support interplanetary spacecraft missions, and radio and radar astronomy observations for the exploration of the Solar System and the universe during Soviet times. It was built to support the space missions of the Soviet Union. Similar networks are run by the USA, China, Europe, Japan, and India.
As of present, the Deep Space Network is maintained by Russia.{{cite news |title=Uzbekistan, Russia to sign Suffa observatory completion plan |url=https://tashkenttimes.uz/science/3038-uzbekistan-russia-to-sign-suffa-observatory-completion-road-map |access-date=24 November 2019 |work=Tashkent Times |date=16 October 2018}}
History
The first Soviet space communications network had 13 stations and was designed to track Earth orbiting satellites, not deep space probes.Don P. Mitchel. [http://www.mentallandscape.com/V_Telemetry.htm Soviet Telemetry Systems. Deep-Space Communication Centers.]
Interplanetary missions require larger antennas, more powerful transmitters, and more sensitive receivers, and an effort was started in 1959 to support the planned 1960 launch of the Venera series of missions to Venus and the Mars program of spacecraft to Mars. The selected design consisted of eight 16-meter dishes placed on two hulls of diesel submarines,{{cite book |title=Soviet Robots in the Solar System: Mission Technologies and Discoveries

These trusses were mounted on bearings from battleship gun turrets. Three such antennas were built: the two North stations for receiving, and the south station a few kilometers away for transmitting.
In 1978, these antennas were augmented by the 70-meter antennas at Yevpatoria and Ussuriisk. Construction on a third antenna at Suffa, Uzbekistan was halted with the collapse of the Soviet Union. As of 16 October 2018, the Director of the radio observatory, Gennady Shanin, announced that a two-year "roadmap" for completing construction had been agreed to by Russia and Uzbekistan.
On June 24, 2024 Ukraine launched at least four missiles at the Yevpatoria facility in Crimea, currently occupied by Russia. Damage to the site and current status is unknown.{{Cite web |last=Axe |first=David |title=The USSR Made A Space Radio Complex Out Of An Old Battleship. 65 Years Later, Ukraine Is Trying To Blow It Up. |url=https://www.forbes.com/sites/davidaxe/2024/06/24/the-ussr-made-a-space-radio-complex-out-of-an-old-battleship-65-years-later-ukraine-is-trying-to-blow-it-up/ |access-date=2024-06-26 |website=Forbes |language=en}}
