RT-70

There are three radio telescopes designated RT-70, all in countries that were once part of the former Soviet Union, all with similar specifications: 70m dishes and an operating range of 5–300 GHz. The Yevpatoria telescope has also been used as a radar telescope in observations of space debris and asteroids.

70-m aerial P-2500 (RT-70 radio telescope) in Yevpatoria.

With their 70m antenna diameter, they are among the largest radio telescopes in the world.

They are:

• the Yevpatoria RT-70 radio telescope at the former soviet Center for Deep Space Communications or West Center for Deep Space Communications, Yevpatoria (Since the 2014 Crimean crisis, the status of Crimea, and thus of the city of Yevpatoria which is located on Crimea, is under dispute between Russia and Ukraine; Ukraine and the majority of the international community considers Crimea and Yevpatoria an integral part of Ukraine, while Russia, on the other hand, considers Crimea and Yevpatoria an integral part of Russia).[1]
• the Galenki RT-70 radio telescope at the East Center for Deep Space Communications, Galenki (Ussuriysk), Russia
• the Suffa RT-70 radio telescope at the Suffa Radio Observatory on the Suffa plateau, Uzbekistan

In 2008, RT-70 was used to beam 501 messages at the exoplanet Gliese 581c, in hopes of making contact with extraterrestrial intelligence. The messages should arrive in 2029.[2]
