List of Kosmos satellites (251–500)
Introduction The designation ''Kosmos'' ( meaning ''Cosmos'') is a generic name given to a large number of Soviet, and subsequently Russian, satellites, the first of which was launched in 1962.Satellites given Kosmos designations include military spacecraft, failed probes to the Moon and the planets, prototypes for crewed spacecraft, and scientific spacecraft. This is a list of satellites with Kosmos designations between 251 and 500.Designation Type Launch date (GMT) Carrier rocket Function Decay/Destruction* Remarks Kosmos 251  Zenit-4M  31 October 196809:14  Voskhod 11A57  Reconnaissance  18 November 1968  Kosmos 252  IS-A  1 November 196800:27  Tsyklon-2A 11K67  ASAT test  1 November 1968*  Intercepted and destroyed Kosmos 248 Kosmos 253  Zenit-2  13 November 196812:00  Voskhod 11A57  Reconnaissance  18 November 1968  Kosmos 254  Zenit-4  21 November 196812:10  Voskhod 11A57  Reconnaissance  29 November 1968  Kosmos 255  Zenit-2  29 November 196812:40  Voskhod 11A57  Reconnaissance  7 December 1968  Kosmos 256  Sfera  30 November 196812:00  Kosmos-3M 11K65M  Geodesy  ''in orbit''  Kosmos 257  DS-P1-Yu  3 December 196814:52  Kosmos-2I 63SM  Radar target  5 March 1969  DS-P1-Yu #17, seventeenth of seventy nine DS-P1-Yu satellites Kosmos 258  Zenit-2  10 December 196808:25  Voskhod 11A57  Reconnaissance  18 December 1968  Kosmos 259  DS-U2-I  14 December 196805:09  Kosmos-2I 63SM  Ionospheric  5 May 1969  DS-U2-I #3, third of three DS-U2-I satellites Kosmos 260  Molniya-1Yu  16 December 196809:15  Molniya-M 8K78M  Communication  9 July 1973  Kosmos 261  DS-U2-GK  19 December 196823:55  Kosmos-2I 63SM  Studied air density in the upper atmosphere and polar auroras. 12 February 1969  Kosmos 261 marked the way to the Intercosmos Program.
