Evpatoria Observatory, Radio telescope in Yevpatoria, Crimea

The Yevpatoria RT-70 is a planetary radar and radio telescope at the Center for Deep Space Communications near Yevpatoria, Crimea. Its 70-meter parabolic dish, designated P-2500 for its 2,500-square-meter area, sits on a white steel support structure above a low round building. The dish's underside shows a lattice of metal ribs and a small rectangular panel near its center.

Construction of the RT-70 antenna at Yevpatoria began in 1973 and was completed in 1978, with the complex commissioned in 1980. It was developed by the Space Instrument Engineering Research Institute as the Kvant-D complex with the P-2500 antenna, primarily for the Mars program. It has supported deep-space missions since 1978, including Venera 11 and 12 and the Vega program.

The telescope is one of only two in the world able to transmit messages to extraterrestrial civilizations. It sent the Cosmic Call in 1999 and 2003, the Teen Age Message in 2001, and A Message from Earth in 2008. The asteroid 6489 Golevka is named after the first letters of Goldstone, Evpatoria and Kashima, the three observatories that radar-studied it.

The telescope stands at the Center for Deep Space Communications near Molochno, in the Yevpatoria area of Crimea. It is a working scientific and military-linked facility, not a museum, so there is no public visitor access or tour route; the dish is seen from outside the perimeter. The 70-meter bowl is best viewed from a distance on the approach road.

The observatory appears on a Russian 100-ruble banknote issued in 2015, featuring its distinctive antenna structure. This honor reflects the site's importance in Russian scientific achievement.
