1959: la sonda soviética Luna 3 transmite las primeras fotografías del lado oculto de la Luna

The Soviet probe Luna 3 transmits the first-ever photographs of the far side of the Moon.

Luna 3, or E-2A No.1, was a Soviet spacecraft launched in 1959 as part of the Luna programme. It was the first mission to photograph the far side of the Moon and the third Soviet space probe to be sent to the neighborhood of the Moon. The historic, never-before-seen views of the far side of the Moon caused excitement and interest when they were published around the world, and a tentative Atlas of the Far Side of the Moon was created from the pictures.
