Luna 2 2" itself. Once "Luna 2" was split from its upper stage it started transmitting information back to Earth using three different transmitters. These transmitters provided precise information on its course, allowing scientists to calculate that "Luna 2" would hit its mark on the Moon around 00:05 on September 14 (Moscow Time). In order to be able to provide a visual from Earth on September 13, the spacecraft released a vapor cloud that would expand to diameter that would be seen by observatories in Alma Ata, Byurakan, Abastumani, Tbilisi, and Stalinabad. This vapor cloud also acted as an experiment to see
Luna 11 kilometers. During the mission, the TV camera failed to return usable images because the spacecraft lost proper orientation to face the lunar surface when a foreign object was lodged in the nozzle of one of the attitude-control thrusters. The other instruments functioned without fault before the mission formally ended on 1 October 1966 after the power supply had been depleted. Luna 11 Luna 11 (E-6LF series) was an unmanned space mission of the Soviet Union's Luna program. It was also called Lunik 11. "Luna 11" was launched towards the Moon from an earth-orbiting platform and entered lunar orbit on 27
