3 mars 1959 - Pioneer 4 Reaches the Moon
Description:
Pioneer 4 becomes the first American spacecraft to escape from the Earth's gravity. It was the first successful mission since 1958. The pressure felt by the US to succeed with a lunar mission was enormous, especially since American mission failures were entirely public while the Soviet failures were kept a secret.Ajouté au bande de temps:
