Kosmos 111 (Russian: Космос 111 meaning Cosmos 111) (E-6S series) was the first Soviet attempt to orbit a spacecraft around the Moon. The design was probably similar to the later successful Luna 10 spacecraft.[1] Kosmos 111 was produced in less than a month, one of two spacecraft developed from the E-6 lander bus in a crash program to upstage America's Lunar Orbiter series and to commemorate the 23rd Congress of the Communist Party (held March 1966).[2].

Launched on March 1, 1966 at 11:03:49 UTC via Molniya 8K78M rocket from 31/6 (COSPAR_ID: 1966-017A, SATCAT: 2093)([3], the mission was a failure. The Blok-L upper stage lost roll control and failed to send the spacecraft on a lunar trajectory. It re-entered the Earth's atmosphere two days later. The craft weighed 14,240lbs and was not immediately acknowledged to be a Luna-series vehicle after its destruction.[1]
