Kosmos 26 (Russian: Космос 26 meaning Cosmos 26), also known as DS-MG No.1 was a scientific satellite which was launched by the Soviet Union in 1964. This mission studied the Earth's magnetic field and, along with Kosmos 49, represented the USSR contribution to the International Quiet Solar Year World Magnetic Survey. The corresponding American measurements were performed by the satellites OGO 2 and OGO 4.
Kosmos 26 was placed into a low Earth orbit with a perigee of 266 kilometres (165 mi), an apogee of 387 kilometres (240 mi), 49.0° of inclination, and an orbital period of 91.0 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.
