Kosmos 391 (Russian: Космос 391 meaning Cosmos 391), also known as DS-P1-I No.11 was a satellite which was used as a radar target for anti-ballistic missile tests. It was launched by the Soviet Union in 1971 as part of the Dnepropetrovsk Sputnik programme.[1]

Launch

It was launched aboard a Kosmos-2I 63SM rocket,[2] from Site 133/1 at Plesetsk. The launch occurred at 12:00:00 UTC on 14 January 1971.[3]

Orbit

Kosmos 391 was placed into a low Earth orbit with a perigee of 267 kilometres (166 mi), an apogee of 803 kilometres (499 mi), 70.9 degrees of inclination, and an orbital period of 95.3 minutes.[1] It decayed from orbit on 21 February 1971.[4]

Kosmos 391 was the tenth of nineteen DS-P1-I satellites to be launched.[1] Of these, all reached orbit successfully except the seventh.[5]
