Advances in NASA Imaging Changed How World Sees Mars

Sixty years ago, NASA’s Mariner 4 captured groundbreaking views of the Red Planet, leading to a steady stream of advances in the cameras used to study other worlds. In 1965, NASA’s Mariner 4 mission brought Mars into American living rooms, where TV sets showed fuzzy black-and-white images of a cratered landscape. The spacecraft took 21 […]

A Miniature Mariner-C

A model of the Mariner-C spacecraft seems to float in the darkness of space in this photo from a June 1964 Conference on New Technology at NASA’s Glenn Research Center in Cleveland. Mariner-C and Mariner-D were identical spacecraft designed by NASA’s Jet Propulsion Laboratory to fly by Mars and photograph the Martian surface. Mariner-C was […]
