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
