1962-05-28 USSR Kosmos 5

Kosmos 5 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. Kosmos 5 was the penultimate MS satellite to be launched, and the last to successfully reach orbit. It was among several satellites inadvertently damaged or destroyed by the Starfish Prime high-altitude nuclear test on 9 July 1962 and subsequent radiation belt.
