Mars is the fourth planet from the Sun.The surface of Mars is orange-red because it is covered in iron(III) oxide dust, giving it the nickname "the Red Planet". [22] [23] Mars is among the brightest objects in Earth's sky, and its high-contrast albedo features have made it a common subject for telescope viewing.
They proposed dividing the history of Mars into three eras: the Phyllocian, Theiikian and Siderikan. [17] [18] The Phyllocian (named after phyllosilicate or clay minerals that characterize the era) lasted from the formation of the planet until around the Early Noachian (about 4.0 Gya).
The human exploration of Mars has been an aspiration since the earliest days of modern rocketry; Robert H. Goddard credits the idea of reaching Mars as his own inspiration to study the physics and engineering of space flight. [144] Proposals for human exploration of Mars have been made throughout the history of space exploration. Currently ...
The Pre-Noachian period is a geological system and early time period on Mars marked by intense meteoroid and asteroid impacts, volcanic and tectonic activity, and the potential presence of surface or subsurface water. [1] The era holds significant importance in Mars' history as it witnessed the planet's formation and the shaping of its ...

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).
The following outline is provided as an overview of and topical guide to Mars: Mars – fourth planet from the Sun and the second-smallest planet in the Solar System , after Mercury . Named after the Roman god of war , it is often referred to as the " Red Planet " [ 1 ] [ 2 ] because the iron oxide prevalent on its surface gives it a reddish ...
However, early in its history Mars may have had conditions more conducive to retaining liquid water at the surface. Mars without a dust storm in June 2001 (on left) and with a global dust storm in July 2001 (on right), as seen by Mars Global Surveyor. Early Mars had a carbon dioxide atmosphere similar in thickness to present-day Earth (1000 hPa ...
