Because of claims that information received from "Luna 1" was fake, the Russian scientists sent a telex to astronomer Bernard Lovell at Jodrell Bank Observatory at the University of Manchester. Having received the intended time of impact, and the transmission and trajectory details, it was Bernard Lovell who confirmed the mission's success to outside observers. However, the American media were still skeptical of the data until Lovell was able to prove that the radio signal was coming from "Luna 2" by showing the Doppler shift from its transmissions.
