Kosmos 611 ( Russian: Космос 611 meaning Cosmos 611), known before launch as DS-P1-Yu No.64, was a Soviet satellite which was launched in 1973 as part of the Dnepropetrovsk Sputnik programme. It was a 400-kilogram (880 lb) spacecraft, which was built by the Yuzhnoye Design Bureau, and was used as a radar calibration target for anti-ballistic missile tests. [1]
Launch
Kosmos 611 was successfully launched into low Earth orbit at 09:29:58 UTC on 28 November 1973. [2] The launch took place from Site 133/1 at the Plesetsk Cosmodrome, [3] and used a Kosmos-2I 63SM carrier rocket.
Orbit
Upon reaching orbit, the satellite was assigned its Kosmos designation, and received the International Designator 1973-094A. [4] The North American Aerospace Defense Command assigned it the catalogue number 06952.
Kosmos 611 was the sixty-seventh of seventy nine DS-P1-Yu satellites to be launched, [1] and the sixty-first of seventy two to successfully reach orbit. [5] It was operated in an orbit with a perigee of 264 kilometres (164 mi), an apogee of 466 kilometres (290 mi), 70.9 degrees of inclination, and an orbital period of 91.8 minutes. [6] It remained in orbit until it decayed and reentered the atmosphere on 19 June 1974. [6]
