The history of Mars observation is about the recorded history of observation of the planet Mars.

In addition, since most Earth-based amateur telescopes are not powerful enough to resolve the topographic surface features of Mars, amateur astronomers still use many of the old feature-names to orient themselves and record their observations. Mars albedo features after the 1958 official list of names, but before the 1972 observations of Mariner 9.
This is a partial list of named channel structures on Mars claimed as outflow channels in the literature, largely following The Surface of Mars by Carr. The channels tend to cluster in certain regions on the Martian surface, often associated with volcanic provinces, and the list reflects this.
A mineral grain from a meteorite preserved evidence that water was present on Mars 4.45 billion years ago, and it may have created hot springs habitable for life. ‘Black Beauty’ was found on ...
Planetary nomenclature, like terrestrial nomenclature, is a system of uniquely identifying features on the surface of a planet or natural satellite so that the features can be easily located, described, and discussed. [1]
An example of an additional object from a spacecraft landing is the metal shroud ejected by the Viking 2 lander, as seen in this 1977 view of Mars. The shroud covered the surface sampler instrument and could be seen in images taken by the lander while it was active on the surface. [11]
