From 1962 to 1973, ten planetary spacecraft were launched under the name Mariner, targeting our neighbors, the inner planets Mercury, Venus, and Mars. There were six missions, most missions launching a pair of Mariner spacecrafts a few months apart. Of the ten launched Magellan spacecrafts, seven were successful in their missions, and three were lost due to launch vehicle failures.

Mariner 2 was the world's first successful interplanetary spacecraft. Launched August 27, 1962, on an Atlas-Agena rocket, Mariner 2 passed within about 34,000 kilometers (21,000 miles) of Venus, sending back valuable new information about interplanetary space and the Venusian atmosphere. Mariner 2 recorded the temperature at Venus for the first time, revealing the planet's very hot atmosphere of about 500 degrees Celsius (900 degrees Fahrenheit). The spacecraft's solar wind experiment measured for the first time the density, velocity, composition and variation over time of the solar wind.
