List of artificial objects on Mars

From The Book of THoTH (Leaves of Wisdom)

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 MER-A Spirit rover and the MER-B Opportunity rover are still operational. The list does not include smaller objects such as parachutes or heatshields.

Notes

¹ Spacecraft reached Martian surface, but contact was not established after landing. (note that Beagle2 may have been found on Mars). [1]

² Spacecraft reached Martian surface, but transmissions stopped after 20 seconds.

³ Spacecraft is assumed to have hit the Martian atmosphere while attempting to enter orbit and fragments may have reached the surface of Mars.
