The history of Mars observation is about the recorded history of observation of the planet Mars. Some of the early records of Mars' observation date back to the era of the ancient Egyptian astronomers in the 2nd millennium BCE. Chinese records about the motions of Mars appeared before the founding of the Zhou dynasty (1045 BCE).
Mars is the only presently known example of a desert planet, a rocky planet with a surface akin to that of Earth's hot deserts. The red-orange appearance of the Martian surface is caused by rust. [41] It can look like butterscotch; [42] other common surface colors include golden, brown, tan, and greenish, depending on the minerals present. [42]
In 2006, researchers using data from the OMEGA Visible and Infrared Mineralogical Mapping Spectrometer on board the Mars Express orbiter proposed an alternative Martian timescale based on the predominant type of mineral alteration that occurred on Mars due to different styles of chemical weathering in the planet's past. They proposed dividing ...
At least two-thirds of Mars' surface is more than 3.5 billion years old, and it could have been habitable 4.48 billion years ago, 500 million years before the earliest known Earth lifeforms; [4] Mars may thus hold the best record of the prebiotic conditions leading to life, even if life does not or has never existed there.

Mars 1962A was a Mars flyby mission, launched on October 24, 1962, and Mars 1962B an intended first Mars lander mission, launched in late December of the same year (1962). Both failed from either breaking up as they were going into Earth orbit or having the upper stage explode in orbit during the burn to put the spacecraft into trans-Mars ...
NASA’s Langley Research Center recently provided a glimpse of what living on the Red Planet could look like.
The estimated volume of an ocean on Mars ranges from 3 meters to about 2 kilometers GEL (Global equivalent layer). This implies that a large amount of water was available on Mars. [40] In 2018, a team of scientists proposed that Martian oceans appeared very early, before or along with the growth of Tharsis. Because of this the depth of the ...
The mystery of Mars's interior has been revealed thanks to marsquakes. Using data compiled by NASA's InSight mission that has detected hundreds of marsquakes since landing on the red planet in ...
