Most of his festivals were held in March, the month named for him Latin Martius , and in October, the months which traditionally began and ended the season for both military campaigning and farming. Under the influence of Greek culture , Mars was identified with the Greek god Ares , [7] whose myths were reinterpreted in Roman literature and art under the name of Mars. The character and dignity of Mars differs in fundamental ways from that of his Greek counterpart, who is often treated with contempt and revulsion in Greek literature. Augustus shifted the focus of Mars' cult to within the pomerium Rome's ritual boundary , and built a temple to Mars Ultor as a key religious feature of his new forum. Unlike Ares, who was viewed primarily as a destructive and destabilizing force, Mars represented military power as a way to secure peace , and was a father pater of the Roman people. His love affair with Venus symbolically reconciled two different traditions of Rome's founding; Venus was the divine mother of the hero Aeneas , celebrated as the Trojan refugee who "founded" Rome several generations before Romulus laid out the city walls.

Mars is the fourth planet from the Sun. It has the biggest volcano in the Solar System, Olympus Mons. Phobos takes 8 hours to orbit mars. Mars on average is C. Mars was named after the God of War. The high amounts of iron in its soil causes a red-orange color, which is why it is known as "the red planet". In Roman mythology, Mars was the god of war taken from Greek mythology, Ares, the god of war it is thought that the planet received this god's name because of its red color. All investigations of Mars, either with telescopes or with exploration craft came to the same result: Mars is a Barren wasteland, marked by craters, vast dune fields littered with rock outcroppings, and perhaps the largest known volcanoes in the solar system. At the moment the presence of life on mars is unknown though growing evidence suggests a lack of, at the least in present times. Today life cannot exist on the surface because that Mars does not have a protective magnetic field to protect against: solar radiation, asteroids, and other stellar particles, this would hinder lifeforms on mars. And the atmosphere is too thin to allow for permanent bodies of liquid water. Liquid water on Mars cannot exist permanently, as the atmospheric pressure on mars is too low to keep liquid, and exposed ice from evaporating. However liquid water had been observed on mars on occasion, usually evaporating not long after leaking from the martian surface. Mars does, however, have two permanent ice caps; composed of frozen Co2 and water ice on both poles.

From Wiktionary, the free dictionary. Aerocapture at Mars for human missions was studied in the 20th century.

The idea of sending humans to Mars has been the subject of aerospace engineering and scientific studies since the late s as part of the broader exploration of Mars. Currently, only robotic landers and rovers have been on Mars. The farthest humans have been beyond Earth is the Moon , under the Apollo program. Conceptual proposals for missions that would involve human explorers started in the early s, with planned missions typically being stated as taking place between 10 and 30 years from the time they are drafted. The plans for these crews have varied—from scientific expeditions, in which a small group between two and eight astronauts would visit Mars for a period of a few weeks or more, to a continuous presence e. Meanwhile, the uncrewed exploration of Mars has been a goal of national space programs for decades, and was first achieved in with the Mariner 4 flyby.

Mars — the fourth planet from the Sun — is a dusty, cold, desert world with a very thin atmosphere. This dynamic planet has seasons, polar ice caps, extinct volcanoes, canyons and weather. If Earth were the size of a dime, Mars would be about as big as an aspirin tablet. Mars orbits our Sun, a star. Mars is the fourth planet from the Sun at an average distance of about million km million miles or 1. One day on Mars takes a little over 24 hours. Mars makes a complete orbit around the Sun a year in Martian time in Earth days. Mars is a rocky planet. Its solid surface has been altered by volcanoes, impacts, winds, crustal movement and chemical reactions.
