Kosmos 26 (Russian: Космос 26 meaning Cosmos 26), also known as DS-MG No.1 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. It also carried a magnetospheric research package as a secondary payload.
Kosmos 26 was placed into a low Earth orbit with a perigee of 268 kilometres (167 mi), an apogee of 376 kilometres (234 mi), 48.9 degrees of inclination, and an orbital period of 91 minutes. It decayed from orbit on 28 September 1964. Kosmos 26 was the first of two DS-MG satellites to be launched, the other being Kosmos 49.
