Its primary mission was to demonstrate an electric gyrodyne orientation system.[1] It also carried several scientific research packages as secondary payloads.[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 05:16 UTC on 24 October 1964.[3] Kosmos 49 was placed into a low Earth orbit with a perigee of {{convert|260|km}}, an apogee of {{convert|472|km}}, 48.9 degrees of inclination, and an orbital period of 91.9 minutes.[1] It decayed from orbit on 21 August 1965.[4] Kosmos 49 was the second of two DS-MG satellites to be launched, the other being Kosmos 26.[1][5] In addition to technological research, it also conducted scientific research into the Earth's magnetosphere, infrared flux and ultraviolet flux.
