Kosmos 440 (Russian: Космос 440 meaning Cosmos 440), also known as DS-P1-I #10 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]
It was launched aboard a Kosmos-2I 63SM rocket,[2] from Site 133/1 at Plesetsk. The launch occurred at 10:30:00 GMT on 24 September 1971.[3]
Kosmos 440 was placed into a low Earth orbit with a perigee of 272 kilometres (169 mi), an apogee of 788 kilometres (490 mi), 70.9 degrees of inclination, and an orbital period of 95.2 minutes.[1] It decayed from orbit on 29 October 1972.[4]
Kosmos 440 was the eleventh of nineteen DS-P1-I satellites to be launched.[1] Of these, all reached orbit successfully except the seventh.[5]
