Kosmos 1

Kosmos 1 ( meaning Cosmos 1), also known as DS-2 No.1 and occasionally in the West as Sputnik 11 was a technology demonstration and ionospheric research satellite launched by the Soviet Union in 1962. It was the first satellite to be designated under the Kosmos system, and the first spacecraft launched as part of the Dnepropetrovsk Sputnik programme to successfully reach orbit. Its primary missions were to measure the performance of its carrier rocket, and to conduct research into the ionosphere.

The Kosmos-1 (GRAU Index: 65S3, also known as Cosmos-1) was a Soviet carrier rocket, derived from the R-14 missile, which was used to orbit satellites in 1964 and 1965. It served as an interim, and was quickly replaced by the Kosmos-3. Eight were flown, and all launches occurred from Site 41/15 at the Baikonur Cosmodrome.
