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.
In ancient Roman religion and mythology, Mars (Latin: Mārs, pronounced [maːrs]) [ 4 ] is the god of war and also an agricultural guardian, a combination characteristic of early Rome. [ 5 ] He is the son of Jupiter and Juno, and was pre-eminent among the Roman army's military gods. Most of his festivals were held in March, the month named for ...
The Mars 1M programs (sometimes dubbed Marsnik in Western media) was the first Soviet uncrewed spacecraft interplanetary exploration program, which consisted of two flyby probes launched towards Mars in October 1960, Mars 1960A and Mars 1960B (also known as Korabl 4 and Korabl 5 respectively).
Life on Mars. The possibility of life on Mars is a subject of interest in astrobiology due to the planet 's proximity and similarities to Earth. To date, no conclusive evidence of past or present life has been found on Mars. Cumulative evidence suggests that during the ancient Noachian time period, the surface environment of Mars had liquid ...
Perseverance, nicknamed Percy, [ 2 ] is a car -sized Mars rover designed to explore the Jezero crater on Mars as part of NASA 's Mars 2020 mission. It was manufactured by the Jet Propulsion Laboratory and launched on July 30, 2020, at 11:50 UTC. [ 3 ] Confirmation that the rover successfully landed on Mars was received on February 18, 2021, at ...
Mars has an orbit with a semimajor axis of 1.524 astronomical units (228 million km) (12.673 light minutes), and an eccentricity of 0.0934. [1][2] The planet orbits the Sun in 687 days [3] and travels 9.55 AU in doing so, [4] making the average orbital speed 24 km/s. The eccentricity is greater than that of every other planet except Mercury ...
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.
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.
