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 {{convert|258|km}}, an apogee of {{convert|537|km}}, 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] See also
