List of artificial objects on Mars

The following table is a partial list of artificial objects on the surface of Mars, consisting of spacecraft which were launched from Earth. Although most are defunct after having served their purpose, the Curiosity and Perseverance rovers are active. China's Tianwen-1 spacecraft is the most recent artificial object to land safely on Mars.

The table does not include smaller objects, such as springs, fragments, parachutes and heat shields. , there are 14 missions with objects on the surface of Mars. Some of these missions contain multiple spacecraft.

Other objects

 * Each mission left debris according to its design. For example, the Schiaparelli EDM lander likely exploded on impact, creating an unknown number of fragments at one location. At another location, there may be a lower heat shield, and at another location, a parachute and upper heat shield. Another example is the counterweights ejected by MSL during its descent. In some cases, the nature and location of this additional debris has been determined and, in other cases, even the location of the main spacecraft has remained unknown. The identification of Beagle 2 after 11 years is one of the greatest breakthroughs yet, since prior to that, it could not be confirmed what had happened. Spacecraft that have not been precisely located include Mars 2, Mars 3, Mars 6, Mars Polar Lander, and the two Deep Space 2 probes.
 * Orbiters whose orbit could eventually decay and impact the surface, include: Viking 1 and Viking 2 orbiters, Mars Reconnaissance Orbiter, 2001 Mars Odyssey, Mars Express, Mars Global Surveyor, Phobos 2, Mars 2, Mars 3, and Mars 5 orbiters, and Mariner 9. (See also List of Mars orbiters)
 * The fate of Mars Climate Orbiter (1999) is unknown, but it is thought to have burnt up in the atmosphere before impacting.
 * 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.

Landing site namings and memorials
Several landing sites have been named, either the spacecraft itself or the landing site:
 * Pennants of Soviet Union on Mars 2 and Mars 3 landers (1971).
 * Thomas Mutch Memorial Station, the Viking 1 lander (1976).
 * Gerald Soffen Memorial Station, the Viking 2 lander (1976).
 * Carl Sagan Memorial Station, Mars Pathfinder (Sojourner) base (1997).
 * Challenger Memorial Station, MER-B (Opportunity) landing site area (2004).
 * Columbia Memorial Station, MER-A (Spirit) landing site area (2004).
 * Green Valley, the Phoenix lander (2008).
 * Bradbury Landing, Curiosity rover landing site (August 6, 2012). (Note: Due to the nature of the landing system, there is no actual space hardware at the touchdown location of Bradbury Landing, see Curiosity (rover))
 * InSight Landing, the InSight lander (2018)
 * Octavia E. Butler Landing, Perseverance rover and Ingenuity helicopter landing site (February 18, 2021)
 * Wright Brothers Field, the initial take-off and landing site for the Ingenuity helicopter, used for five flights (April, May, 2021)
 * Three Forks Sample Depot, backup sample Depot of Perseverance cached samples for return to Earth by NASA-ESA Mars Sample Return Mission (2022)
