Origins & Early Life

Mariner 10 was an American robotic space probe launched by NASA on 3 November 1973, to fly by the planets Mercury and Venus. It was the first spacecraft to visit Mercury and the first to perform a flyby of multiple planets. Mariner 10 was launched approximately two years after Mariner 9 and was the last spacecraft in the Mariner program.

Career & Major Achievements

(Mariner 11 and Mariner 12 were allocated to the Voyager program and redesignated Voyager 1 and Voyager 2.) The mission objectives were to measure Mercury's environment, atmosphere, surface, and body characteristics and to make similar investigations of Venus. Secondary objectives were to perform experiments in the interplanetary medium and to obtain experience with a dual-planet gravity assist mission. Mariner 10's science team was led by Bruce C. Murray at the Jet Propulsion Laboratory.

Enduring Legacy & Impact

Mariner 10 was the first mission to use a gravity assist from one planet (in this case, Venus) to reach another planet. It used Venus to bend its flight path and bring its perihelion down to the level of Mercury's orbit.
