Mariner 9 (Mariner Mars '71 / Mariner-I) was a robotic spacecraft that contributed greatly to the exploration of Mars and was part of the NASA Mariner program.
In 1971, the Mariner 9 spacecraft beat the Soviet Mars 2 to the Red Planet to become the first spacecraft to orbit another planet. While in orbit, Mariner 9 mapped 85 percent of the Martian surface, an objective it inherited from the failed Mariner 8 mission, and collected valuable information about Mars' surface and atmosphere.
NASA’s Mariner 9 beat the Soviet Mars 2—which had an 11-day head start—to Mars, becoming the first spacecraft to orbit another planet. The orbiter mapped 85% of the Martian surface and sent back more than 7,000 pictures, including images of Olympus Mons, Valles Marineris, and Phobos and Deimos.
