Kosmos 51 (Russian: Космос 51 meaning Cosmos 51), also known as DS-MT No.3 was a technology demonstration satellite which was launched by the Soviet Union in 1964 as part of the Dnepropetrovsk Sputnik programme. Its primary mission was to demonstrate an electric gyrodyne orientation system.[1] It also carried a scientific research package as a secondary payload, which was used to study cosmic rays and the luminosity of space.[1]

It was launched aboard a Kosmos-2I 63S1 rocket[2] from Site 86/1 at Kapustin Yar. The launch occurred at 23:02 UTC on 9 December 1964.[3]

Kosmos 51 was placed into a low Earth orbit with a perigee of 258 kilometres (160 mi), an apogee of 537 kilometres (334 mi), 48.8 degrees of inclination, and an orbital period of 92.6 minutes.[1] It decayed from orbit on 14 November 1965.[4] Kosmos 51 was the last of three DS-MT satellites to be launched. The first was lost in a launch failure in June 1963, and the second was launched as Kosmos 31 in June 1964.[1][5]
