Luna 3:
Luna 3's goal was to take the first photographs of the far side of the Moon, a region never seen by human eyes. It also carried micrometeroid and cosmic ray detectors.

Although the spacecraft suffered heating and communication problems, it took 29 photographs of the far side of the moon with wide angle and telephoto lenses. The spacecraft developed the film and then beamed the images back to Earth, providing humanity with its first fuzzy look at the dark side of the Moon.

Seventeen of Luna 3's 29 images were usable. Luna 3's images covered 70 percent of surface of the lunar far side. They were used to create the first rudimentary atlas. The images prompted scientists to revise their theories of lunar evolution.
