Kosmos 111 (Russian: Космос 111 meaning Cosmos 111), E-6S No.204,[3] was the first Soviet attempt to orbit a spacecraft around the Moon. The design was similar to the future successful Luna 10 spacecraft.[4] 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 of the Soviet Union (CPSU), held in March 1966.[5]
