In 1999, Mars Climate Orbiter accidentally entered Mars' atmosphere and either burnt up or left Mars' orbit on an unknown trajectory.^{[citation needed]}

There are a number of derelict spacecraft orbiting Mars whose location is not known precisely. There is a proposal to use the Optical Navigation Camera on the Mars Reconnaissance Orbiter to search for small moons, dust rings and old orbiters.^[45] 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 atmosphere and either burn up, or crash into the planet's surface.^[48]

Timeline

There have also have been proposed missions dedicated to explore the two moons of Mars, Phobos and Deimos. Many missions to Mars have also included dedicated observations of the moons, while this section is about missions focused solely on them. There have been three unsuccessful dedicated missions and many proposals. Because of the proximity of the Mars moons to Mars, any mission to them may also be considered a mission to Mars from some perspectives.

There have been at least three proposals in the United States Discovery Program, including PADME, PANDORA, and MERLIN.^[50] The ESA has also considered a sample return mission, one of the latest known as Martian Moon Sample Return or MMSR, and it may use heritage from an asteroid sample return mission.^[51]

In Japan, the Institute of Space and Astronautical Science (ISAS) is developing a sample return mission to Phobos.^[68][69] This mission is called Martian Moons eXploration (MMX)^[70] and is a flagship Strategic Large Mission.^[71] MMX will build on the expertise the Japan Aerospace Exploration Agency (JAXA) would gain through the Hayabusa2 and SLIM missions.^[72] As of December 2023, MMX is scheduled to launch in 2026.^[73]

Three missions to land on Phobos have been launched; the Phobos program in the late 1980s saw the launch of Fobos 1 and Fobos 2, while the Fobos-Grunt sample return mission was launched in 2011. None of these missions were successful: Fobos 1 failed en route to Mars, Fobos 2 failed shortly before landing, and Fobos-Grunt never left low Earth orbit.

Missions sent to the Martian system have returned data on Phobos and Deimos and missions specifically dedicated to the moons are a subset of missions Mars that often include dedicated goals to acquire data about these moons. An example of this is the imaging campaigns by Mars Express of the Mars moons.

Osiris-Rex 2 was a proposal to make OR a double mission, with the other one collecting samples from the two Mars moons.^[74] In 2012, it was stated that this mission would be both the quickest and least expensive way to get samples from the Moons.^[59]

The 'Red Rocks Project,' a part of Lockheed Martin's "Stepping Stones to Mars" program, proposed to explore Mars robotically from Deimos.^[75][76]
