Kosmos 5 ({{langx|ru|Космос 5}} meaning Cosmos 5), also known as 2MS #2 and occasionally in the West as Sputnik 15 was a scientific research and technology demonstration satellite launched by the Soviet Union in 1962. It was the fifth satellite to be designated under the Kosmos system, and the third spacecraft to be launched as part of the MS programme, after Kosmos 2 and Kosmos 3. Its primary missions were to develop systems for future satellites, and to record data about artificial radiation around the Earth.{{cite web|url=http://www.astronautix.com/craft/2ms.htm|title=2MS|last=Wade|first=Mark|publisher=Encyclopedia Astronautica|accessdate=2009-05-23|url-status=dead |archiveurl=https://web.archive.org/web/20081007132505/http://astronautix.com/craft/2ms.htm|archivedate=2008-10-07}}
Spacecraft
Kosmos 5 was a 2MS satellite, the second of two to be launched, following the first which was launched as Kosmos 3 on 24 April 1962. The 2MS was the second of two types of MS satellite to be launched, following the first 1MS spacecraft which had been launched as Kosmos 2. Kosmos 5 was the penultimate MS satellite to be launched, and the last to successfully reach orbit. The last launch attempt, of a 1MS satellite, occurred on 25 October 1962, and failed to reach orbit.{{cite web|url=http://www.astronautix.com/project/ms.htm|archive-url=https://web.archive.org/web/20020309043707/http://www.astronautix.com/project/ms.htm|url-status=dead|archive-date=9 March 2002|title=MS |last=Wade|first=Mark|publisher=Encyclopedia Astronautica|accessdate=2009-05-23}} It had a mass of 280 kg.{{Cite web|url=https://nssdc.gsfc.nasa.gov/nmc/spacecraft/display.action?id=1962-020A|title=Cosmos 5: Display 1962-020A|date=27 February 2020|website=nssdc.gsfc.nasa.gov|publisher=NASA|access-date=23 April 2020}} {{PD-notice}}

Kosmos 5 was among several satellites inadvertently damaged or destroyed by the Starfish Prime high-altitude nuclear test on 9 July 1962 and subsequent radiation belt.
