1964: Mariner 4 successfully launched from Cape Kennedy on its 324-million-mile “fly-by” trip to Mars.
Mariner 4 was the fourth in a series of spacecraft intended for planetary exploration in “fly-by” mode. It was designed to conduct closeup scientific observations of Mars and to transmit these observations to Earth. Mariner 4 performed the first successful flyby of the planet Mars, returning the first close-up pictures of the Martian surface. It captured the first images of another planet ever returned from deep space impacting the scientific community’s view of life on Mars. Mariner 4 (Jet Propulsion Lab) continued to operate properly after two years in space. It had flown 1,025,082,830 miles by this date in 1966.
