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-Glob of the Luna 25 lander in 2017. As of August 2018, Luna 25 is planned to be launched in 2021, Luna 26 in 2022, Luna 27 in 2023, Luna 28 in 2024, and Lunas 29, 30, 31 in 2026. The Luna-Glob programme is a continuation of the Soviet Union Luna programme that sent at least twenty-four orbiters and landers between 1959 and 1976 to the Moon, of which fifteen were successful. The last mission was Luna 24, launched on 9 August 1976. Initially, the first Luna-Glob mission was planned as orbiter with ground penetrating sensors. Four Japanese-built penetrators inherited from
