Summary
Proton 1 launched on a Soviet Space Program UR-500 from 81/23 (81L), Baikonur Cosmodrome, Republic of Kazakhstan on July 16, 1965. It was Soviet Space Program's 133rd launch, 25th this year and humanity's 455th orbital launch attempt. It was the 1st UR-500 flight. The payload was bound for low Earth orbit (LEO). The tracked orbit of Proton, one of 4 catalogued objects, from July 23, 1965, was 182 × 608 km inclined 63.5°. 4 objects from this launch are catalogued, one of them a payload.
