Kosmos 31 (Russian: Космос 31 meaning Cosmos 31), also known as DS-MT No.2 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.[1]

It was launched aboard a Kosmos-2I 63S1 rocket[2] from pad 2 of the Mayak Launch Complex at Kapustin Yar. The launch occurred at 06:00 UTC on 6 June 1964.[3]

Kosmos 31 was placed into a low Earth orbit with a perigee of 221 kilometres (137 mi), an apogee of 485 kilometres (301 mi), 48.9 degrees of inclination, and an orbital period of 91.7 minutes.[1] It decayed from orbit on 20 October 1964.[4] Kosmos 31 was the second of three DS-MT satellites to be launched. The first was lost in a launch failure in June 1963, and the third was Kosmos 51, which was launched in December 1964.[1][5]
