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.
The geology of Mars is the scientific study of the surface, crust, and interior of the planet Mars. It emphasizes the composition, structure, history, and physical processes that shape the planet. It is analogous to the field of terrestrial geology. In planetary science, the term geology is used in its broadest sense to mean the study of the ...
Climate of Mars. Mars' cloudy sky as seen by Perseverance rover in 2023, sol 738. The climate of Mars has been a topic of scientific curiosity for centuries, in part because it is the only terrestrial planet whose surface can be easily directly observed in detail from the Earth with help from a telescope. Although Mars is smaller than the Earth ...
Mars is located 142,000,000 miles away from the Sun. Named after the Roman God of war, Mars is widely known for its blood-red color. Chinese astronomers even used to call Mars the 'fire star'.
Both sets of findings support an origin of Phobos from material ejected by an impact on Mars that reaccreted in Martian orbit, [40] similar to the prevailing theory for the origin of Earth's moon. The moons of Mars may have started with a huge collision with a protoplanet one third the mass of Mars that formed a ring around Mars.
On October 13, 1590, the German astronomer Michael Maestlin observed an occultation of Mars by Venus. [23] One of his students, Johannes Kepler, quickly became an adherent to the Copernican system. After the completion of his education, Kepler became an assistant to the Danish nobleman and astronomer, Tycho Brahe.
Emirates Mars Mission. The Emirates Mars Mission (Arabic: مشروع الإمارات لاستكشاف المريخ, romanized: mašrū' al-Imārāt l-āstikšāf al-Murīkh) is a United Arab Emirates Space Agency uncrewed space exploration mission to Mars. The Hope probe (Arabic: مسبار الأمل, Misbar Al-Amal) was launched on 20 July ...
The geological history of Mars follows the physical evolution of Mars as substantiated by observations, indirect and direct measurements, and various inference techniques. Methods dating back to 17th-century techniques developed by Nicholas Steno, including the so-called law of superposition and stratigraphy, used to estimate the geological ...
