The unmanned spacecraft Mariner 4 passes over Mars at an altitude of6,000 feet and sends back to Earth the first close-up images of the redplanet.
Launched in November 1964, Mariner 4 carried a television camera and sixother science instruments to study Mars and interplanetary space withinthe solar system. Reaching Mars on July 14, 1965, the spacecraft begansending back television images of the planet just after midnight on July15. The pictures–nearly 22 in all–revealed a vast, barren wasteland ofcraters and rust-colored sand, dismissing 19th-century suspicions thatan advanced civilization might exist on the planet. The canals thatAmerican astronomer Percival Lowell spied with his telescope in 1890proved to be an optical illusion, but ancient natural waterways of somekind did seem to be evident in some regions of the planet.
Once past Mars, Mariner 4 journeyed on to the far side of the sun beforereturning to the vicinity of Earth in 1967. Nearly out of power by then,communication with the spacecraft was terminated in December 1967.
