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 ". [21] [22] 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.
Geology of Mars. Generalised geological map of Mars [1] Mars as seen by the Hubble Space Telescope. 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.
On October 13, 1590, the German astronomer Michael Maestlin observed an occultation of Mars by Venus. [24] One of his students, Johannes Kepler, quickly became an adherent to the Copernican system.

It only takes up about 15% of the Earth's volume. It would take about six Mars-sized planets to fill up the entire volume of Earth. Mars' size difference also affects the force on its surface. If ...

Mars-1 was the first spacecraft launched to Mars in 1962, but communication was lost while en route to Mars. With Mars-2 and Mars-3 in 1971–1972, information was obtained on the nature of the surface rocks and altitude profiles of the surface density of the soil, its thermal conductivity, and thermal anomalies detected on the surface of Mars.
Spirit, also known as MER-A ( Mars Exploration Rover – A) or MER-2, is a Mars robotic rover, active from 2004 to 2010. [3] Spirit was operational on Mars for 2208 sols or 3.3 Martian years (2269 days; 6 years, 77 days ). It was one of two rovers of NASA 's Mars Exploration Rover Mission managed by the Jet Propulsion Laboratory (JPL).
The Mars Reconnaissance Orbiter (MRO) is a multipurpose spacecraft designed to conduct reconnaissance and exploration of Mars from orbit. The US$720 million spacecraft was built by Lockheed Martin under the supervision of the Jet Propulsion Laboratory, launched August 12, 2005, and entered Mars orbit on March 10, 2006.
