Kosmos (Russian: Космос meaning Cosmos) is a series of satellites which were launched by the Soviet Union and are being launched now by Russia. The first of them was launched on March 16, 1962.

Any satellite which doesn't fit into any particular program is designated as a Kosmos satellite.^{[citation needed]} As of November 14, 2008 2,445 Kosmos satellites had been launched. The satellites have very different roles, early ones were used for scientific exploration, some of them are failed interplanetary probes. It is suspected^[who?] that most are military reconnaissance satellites and satellites for other military uses.^{[citation needed]}

Early Kosmos satellites had typic body which could be equipped with various equipment.^{[citation needed]} There were six classes, labelled Kosmos A, B, C, D, E and F^{[citation needed]} (a satellite of each class would be numbered independently of this). Later satellites had different bodies.

The designation is given only to satellites which are in Earth orbit. Typically, Soviet planetary missions were initially put into an Earth parking orbit as a launch platform with a rocket engine and attached probe, which would then be launched toward its targets with an engine burn with a duration of roughly 4 minutes. If the engine misfired or the burn was not completed, the probes which would be left in Earth orbit would be given a Kosmos designation, which allowed the Soviets to claim a more successful record for their planetary exploration programs, and also may have helped further disguise genuine military satellites of the Kosmos series.^{[citation needed]}

Some of the Kosmos satellites are the so-called RORSAT Radar-equipped Ocean Reconnaissance Satellites.

Some Kosmos satellites are equipped with nuclear reactors.

Early Kosmos satellites

Kosmos 1

Kosmos 1, also known as Sputnik 11, was launched on March 16, 1962 at 12:00:00 UTC. Orbital mass 285 kg. It was the first satellite of the Soviet Earth Satellite series^[1]. Employed radio instruments in order to study the structure of the ionosphere.

Kosmos 2

Kosmos 2, also known as Sputnik 12, was launched on April 6 1962 at 17:16:00 UTC. Orbital mass 285 kg. It was the second satellite of the Soviet Earth Satellite series^[1]. Employed radio instruments in order to study the structure of the ionosphere.

Kosmos 3

Kosmos 3, also known as Sputnik 13, was launched on April 24 1962 at 04:04:00 UTC. Orbital mass 330 kg. It belongs to the Soviet Earth Satellite series^[1]. It was used to study the upper layers of the atmosphere, Earth and the outer space. Data was relayed to Earth by a multichannel telemetry systems equipped with space-borne memory units.

Kosmos 4

Kosmos 4, also known as Sputnik 14, was launched on April 26 1962 at 10:04:00 UTC. Orbital mass 4600 kg. It was used to study the upper layers of the atmosphere, Earth and the outer space. It was developed to measure radiation before and after nuclear tests conducted during the US project Starfish^[1]. Data was relayed to Earth by a multichannel telemetry systems equipped with space-borne memory units.

Kosmos 5

Kosmos 5, also known as Sputnik 15, was launched on May 28 1962 at 03:07:00 UTC. Orbital mass 280 kg. It was used to study the upper layers of the atmosphere, Earth and the outer space. Data was relayed to Earth by a multichannel telemetry systems equipped with space-borne memory units^[1].

Kosmos 6

Kosmos 6, also known as Sputnik 16, was launched on June 30 1962 at 16:04:00 UTC from Kapustin Yar. Orbital mass 355 kg. It was a Soviet DS (Dnepropetrovsk Sputnik) type military satellite built in Ukraine for launch by Kosmos launch vehicles. It was used for military and scientific research and component proving tests^[1].

Kosmos 7

Kosmos 7, also known as Sputnik 17, was launched on July 28 1962 at 09:21:00 UTC. Orbital mass 4600 kg. It was used to study the upper layers of the atmosphere, Earth and the outer space. Data was relayed to Earth by a multichannel telemetry systems equipped with space-borne memory units. It was used to measure radiation in the space environment in order to guarantee safety during the flight of the Vostok 3 and Vostok 4 spacecrafts^[1].

Kosmos 8

Kosmos 8, also known as Sputnik 18, was launched on August 18 1962 at 05:02:00 UTC from Kapustin Yar. Orbital mass 337 kg. It was a Soviet DS (Dnepropetrovsk Sputnik) type military satellite built in Ukraine for launch by Kosmos launch vehicles. It was used for military and scientific research and component proving tests^[1].
