Historians presume this spacecraft was to be a lunar orbiter.


None. The spacecraft achieved Earth orbit, but the rocket that was to send it to the Moon failed to fire. The spacecraft re-entered Earth's atmosphere two days after launch.

In Depth

In early 1966, the Soviets began hastily putting together an interim lunar orbiter program, the Ye-6S, partly to upstage the American Lunar Orbiter project and partly to commemorate the 23rd Congress of the Communist Party held in March 1966.

Engineers quickly designed a set of two rudimentary probes using the old Ye-6 (lander) buses for these missions. The first of them was prepared in less than a month but failed to leave Earth orbit.

During Earth-orbit operations, the Blok L upper stage lost roll control and failed to fire to send the probe towards the Moon. The official Soviet media named the stranded satellite Kosmos 111; it re-entered Earth's atmosphere two days after launch.


Launch Vehicle: Molniya-M
