DS-U2-MT (Kosmos 461) [Yuzhnoye]

The DS-U2-MT satellite was a Soviet scientific satellite launched as part of the Dnepropetrovsk Sputnik program. It investigated micrometeoroids and conducted gamma ray astronomy.

This satellite measured low-energy and high-energy component intensity variations of charged-particle flows, studied radiation intensity and spectral composition over a wide range, from X-ray to hard gamma radiation, and studied radiation variations and a correlation with the activity of principal meteor showers.

The satellite was launched on a Kosmos-3M from the Plesetsk cosmodrome.

Kosmos 461 reached an orbit with a perigee of 486 km, an apogee of 508 km and an inclination of 69.2. It completed operations on 14 December 1972, and decayed from orbit and reentered the atmosphere on 21 February 1979.
