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]
[8] [9] Mariner 9 Orbiter: Mars 30 May 1971 14 November 1971 entered orbit: 169 days (5 mo, 16 d) Mariner 9 was the first spacecraft to orbit another planet. It remained active until 27 October 1972.

Launch of Mariner 1 in 1962. The Mariner program was conducted by the American space agency NASA to explore other planets.Between 1962 and late 1973, NASA's Jet Propulsion Laboratory (JPL) designed and built 10 robotic interplanetary probes named Mariner to explore the inner Solar System – visiting the planets Venus, Mars and Mercury for the first time, and returning to Venus and Mars for ...
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]

In derelict orbit around Mars, expected to decay no sooner than 2022 [14] First spacecraft to orbit another planet First Mars orbiter Mars 2 orbiter USSR 27 November 1971 [15] Mission terminated 22 August 1972; spacecraft in derelict orbit First Soviet spacecraft to orbit Mars Mars 3 ...
As of 2016, there were believed to be eight derelict spacecraft in orbit around Mars (barring unforeseen event). [46] The Viking 1 orbiter was not expected to decay until at least 2019. [ 47 ] Mariner 9 , which entered Mars orbit in 1971, was expected to remain in orbit until approximately 2022, when it was projected to enter the Martian ...
Mariner 9, which entered Mars orbit in 1971, is expected to remain in orbit until approximately 2022, when the spacecraft is projected to enter the Martian atmosphere and either burn up or crash into the planet's surface. [13]
