History of spaceflight of studying the moon.The program ran from 1959 to 1976 and consisted of 15 successful missions, the program achieved many first achievements and collected data on the Moon's chemical composition, gravity, temperature, and radiation. Luna 2 became the first man made object to make contact with the moons surface in September 1959. Luna 3 returned the first photographs of the far side of the moon in October 1959. The Vostok Programme the first Soviet spaceflight project to put the Soviet citizens into low Earth orbit and return them safely. The programme carried out six manned spaceflights between 1961 and 1963.
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
