Luna 5 failures, the soft landing attempt failed, and "Luna 5" impacted the Moon. The place of impact was firstly announced as (coast of Mare Nubium), but later it was estimated as (near crater Copernicus). It was the second Soviet spacecraft to reach the surface of the Moon, following "Luna 2" in 1959. An observatory noted a plume produced by the impact, which was visible for ten minutes. Luna 5 Luna 5, or E-6 No.10, was an unmanned Soviet spacecraft intended to land on the Moon as part of the Luna programme. It was intended to become the first spacecraft to achieve
Luna 2 time of impact, and the transmission and trajectory details. Even though Soviet scientists gave all this information, the Americans were still skeptical until Bernard Lovell was able to prove that the radio signal was coming from "Luna 2" by showing the Doppler shift from its transmissions. After this no one seemed to question the veracity of the Soviets. "Luna 2" showed time variations in the electron flux and energy spectrum in the Van Allen radiation belt. The spacecraft also carried Soviet pennants. Two of them, located in the spacecraft, were sphere-shaped, with the surface covered by identical pentagonal elements. In
