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 2 devices were searching for lunar magnetic and radiation fields similar to the Van Allen radiation belt around Earth, sending information about once every minute until its last transmission which came about 55 km away from the lunar surface. Although it did prove previous measurements of the Van Allen radiation belts that were taken from Luna 1 around the Earth, it was not able to detect any type of radiation belts around the Moon. Because of claims that information received from Luna 1 was fake, as soon as the scientists of "Luna 2" started receiving transmissions they sent out the intended
