Mariner 9 orbited Mars in November 13, 1971.
Mariner 9 was a NASA space probe that became the first spacecraft to orbit another planet when it entered orbit around Mars in 1971. It mapped 85% of the Martian surface, providing valuable data and images that revolutionized our understanding of the planet.
The first satellite sent to Mars was called Mariner 4. It was launched by NASA in 1964 and successfully conducted a flyby of the planet in 1965, sending back the first close-up images of Mars' surface.
Mariner 4 (USA) was the first successful fly by mission, which was launched in 1964. Mariner 9 (USA) was the first probe to orbit another planet (Mars) when it entered into orbit around Mars on November 14, 1971. Mars 2 & 3(USSR) were the first probes to "land" on Mars - probably crashed in 1971 Viking 1 & 2 (USA) were the first probes to successfully land in 1976. See related link for more information.
Mariner 9 was launched successfully on May 30, 1971. This made it the first artificial satellite of Mars when it arrived and went into orbit.
Mariner 9 took on that spacecraft's mission of mapping 70 percent of the Martian surface in addition to its own objective of studying changes over time in the Martian atmosphere and surface.

It didn't, it flew by Venus October 19, 1967.
Mariner 9 was sent out by NASA to orbit Mars and study the planet's surface, atmosphere, and climate. It was the first spacecraft to orbit another planet and provided valuable data on Mars, including detailed images of the surface that revealed features like volcanoes and valleys.
Mariner 4 was the first ship to visit Mars.

None, since satellites don't "land", they orbit. There are 6 landers and rovers on the Martian surface, 2 of which were lost at arrival. NASA reports 3 types of Martian Exploration missions: (1) Fly-by missions: Mariner 3, Mariner 4, Mariner 6, Mariner 7 (2) Orbiter missions (the satellites): Mariner 8, Mariner 9, Viking 1, Viking 2, Mars Observer, Mars Global Surveyor, Mars Climate Orbiter, 2001 Mars Odyssey, Mars Express, Mars Reconnaissance Orbiter (3) Lander and Rover missions: Viking 1 Lander, Viking 2 Lander, Pathfinder Rover, Polar Lander (lost), Deep Space 2 (lost), Spirit Rover, Opportunity Rover, Phoenix Mars Science Laboratory Rover is scheduled to launch in 2011.
They were the Mariner 1 and Mariner 2 spacecrafts.
