List of artificial objects on Mars

From Wikipedia, the free encyclopedia

The following table is a partial list of artificial objects on the surface of Mars. Most are defunct after having served their purpose, but the Spirit rover and the Opportunity rover are still operational. The list does not include smaller objects such as parachutes, heatshields, and the landers of the MER rovers.

[edit] Notes

¹ Spacecraft reached Martian surface, but contact was not established after landing.

² Spacecraft reached Martian surface, but transmissions stopped after 25 seconds.

³ Spacecraft is assumed to have hit Mars while attempting to enter orbit and parts of the spaceship may have reached the surface of Mars.

⁴ Active rover as of January 2007.
