{{More references|date=July 2013}} [[File:70-м антенна П-2500 (РТ-70).jpg|thumb|70-m aerial P-2500 (RT-70 radio telescope) in Yevpatoria.]] 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. They are a part of the former Soviet Deep Space Network, now operated by Russia. The Yevpatoria facility has also been used as a radar telescope in observations of space debris and asteroids.
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, Crimea, Ukraine. * 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. Never completed.
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.<ref>{{cite news|url=https://www.telegraph.co.uk/news/newstopics/howaboutthat/3166709/Messages-from-Earth-sent-to-distant-planet-by-Bebo.html|title=Messages from Earth sent to distant planet by Bebo |last=Moore |first=Matthew|date=9 October 2008 |publisher=.telegraph.co.uk|accessdate=9 October 2008| archiveurl= https://web.archive.org/web/20081011142445/http://www.telegraph.co.uk/news/newstopics/howaboutthat/3166709/Messages-from-Earth-sent-to-distant-planet-by-Bebo.html| archivedate= 11 October 2008 | url-status= live}}</ref>
