Kosmos 149 (Russian: Космос 149 meaning Cosmos 149), also known as DS-MO No.1 was a technology demonstration satellite which was launched by the Soviet Union in 1967 as part of the Dnepropetrovsk Sputnik programme. Its primary mission was to demonstrate orientation control by means of an aerodynamic skirt stabiliser. It also carried an optical research payload for the Soviet Armed Forces and had a mass of 375 kilograms (827 lb).
Kosmos 149 was placed into a low Earth orbit with a perigee of 243 kilometres (151 mi), an apogee of 285 kilometres (177 mi), an inclination of 48.4°, and an orbital period of 89.76 minutes. It decayed from orbit on 7 April 1967. Kosmos 149 was the first of two DS-MO satellites to be launched. It was succeeded by Kosmos 320, which was launched in January 1970.
