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.Mariner 9 was launched toward Mars on May 30, 1971, [2] [3] from LC-36B at Cape Canaveral Air Force Station, Florida, and reached the planet on November 14 of the same year, [2] [3] becoming the first spacecraft to orbit another planet ...
Viking 1 orbiter, likely to be in orbit as of 2019. [9] Mariner 9 was expected to remain in orbit until approximately 2022, when the spacecraft was projected to enter the Martian atmosphere and either burn up or crash into the planet's surface. [10] Mars Global Surveyor is predicted to orbit until 2046 (50 years after insertion). [11]
Mariner 10: Venus 3 November 1973 5 February 1974 95 days (3 months, 3 days) Mariner 10 flew by Venus at a minimum distance of 5768 km. It was the first use of a gravity assist by an interplanetary spacecraft. [92] Mercury 29 March 1974 147 days (4 months, 27 days) Mariner 10 flew by Mercury at a minimum distance of 704 km. 21 September 1974 ...
Sisterships Mariner 3 and Mariner 4 were Mars flyby missions. [18] Mariner 3 was launched on November 5, 1964, but the shroud encasing the spacecraft atop its rocket failed to open properly and Mariner 3 did not get to Mars. [1] Mariner 4, launched on November 28, 1964, was the first successful flyby of the planet Mars and gave the first ...
The first artificial satellite to orbit another planet — the U.S. probe Mariner 9 — entered areocentric orbit on 13 November 1971. [1] Within a month, Mariner 9 was joined in orbit by two Soviet orbiters: Mars 2 (27 November 1971) and Mars 3 (2 December 1971). [2]

Mariner 9 imaging revealed the first direct evidence of water in the form of river beds, canyons (including the Valles Marineris, a system of canyons over about 4,020 kilometres (2,500 mi) long), evidence of water erosion and deposition, weather fronts, fogs, and more. [1] The findings from the Mariner 9 missions underpinned the later Viking ...
