Kosmos 9 (Russian: Космос 9 meaning Cosmos 9), also known as Zenit-2 #7, was a Soviet reconnaissance satellite launched in 1962. It was the ninth satellite to be designated under the Kosmos system, and the third successful launch of a Soviet reconnaissance satellite, following Kosmos 4 and Kosmos 7.[1]

Vostok-2 s/n T15000-06 was used to launch Kosmos 9.[2] The launch was conducted from Site 1/5 at the Baikonur Cosmodrome, and occurred at 09:39:51 GMT on 27 September 1962.[3]

Kosmos 9 was placed into a low Earth orbit with a perigee of 829 kilometres (515 mi), an apogee of 981 kilometres (610 mi), 67.6 degrees of inclination, and an orbital period of 103.1 minutes.[1] It conducted a four-day mission, before being deorbited and landing by parachute on 1 October.[4]

Kosmos 9 was a Zenit-2 satellite, a reconnaissance satellite derived from the Vostok spacecraft used for manned flights.[1] The next Zenit-2 launch was Kosmos 10.[1] Kosmos 9 carried an area survey reconnaissance payload. In addition to reconnaissance, it was also used for research into radiation in support of the Vostok programme.
