Kosmos 7 (Russian: Космос 7 meaning Cosmos 7), also known as Zenit-2 #4 and occasionally in the West as Sputnik 17 was a Soviet reconnaissance satellite launched in 1962. It was the seventh satellite to be designated under the Kosmos system, and the second successful launch of a Soviet reconnaissance satellite.[1] It also marked the first successful launch of a Vostok-2, on the second attempt. The first Vostok-2 launch, also carrying a Zenit-2 satellite, suffered an engine failure seconds after launch, fell back to earth and exploded within 300 metres of the launch pad.
Vostok-2 s/n T15000-07 was used to launch Kosmos 7.[2] The launch was conducted from Site 1/5 at the Baikonur Cosmodrome, and occurred at 09:18:31 GMT on 28 July 1962.[3]
Kosmos 7 was placed into a low Earth orbit with a perigee of 197 kilometres (122 mi), an apogee of 356 kilometres (221 mi), 64.9 degrees of inclination, and an orbital period of 90 minutes.[1] It conducted a four day mission, before being deorbited and landing by parachute on 1 August.[4]
Kosmos 7 was a Zenit-2 satellite, a reconnaissance satellite derived from the Vostok spacecraft used for manned flights.[1] It was the second Zenit-2 to reach orbit, the first being Kosmos 4. The next Zenit-2 launch was Kosmos 9.[1] Kosmos 7 carried an area survey reconnaissance payload. In addition to reconnaissance, it was also used for research into radiation.
