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
