| - Mars is the fourth planet from the Sun in the Sol System. The planet is named after Mars, the Roman god of war; it is also referred to as the New World, the Red Planet, and the 4th Rock. Home to millions of species, including humans, Mars is the second planet ever to support human civilization after achieving human rated habitability in 2081, after 50 years of terraforming. Mars is a relatively dry planet with only half of its surface covered in Water. Mars is a terrestrial planet with an atmosphere conditioned to be as thick as Earth’s, having surface features reminiscent both of the impact craters of the Moon and the volcanoes, valleys, deserts and polar ice caps of Earth. The first humans began exploring Mars in the early 2020s after decades of robotic exploration; the first research colonies sprang up on the surface by the middle of the decade; and in 2030 humans began the decades long process of terraforming Mars into a habitable world. Since then, humans have significantly altered the atmosphere and other abiotic conditions on the planet, enabling the proliferation of organisms as well as the formation of the ozone layer which, together with Mars’s restored magnetic field, blocks harmful radiation, permitting macroscale life on the surface. The physical properties of the planet Mars, as well as its geological history and orbit, allowed life to persist naturally during a brief period roughly 3 billion years ago, prior to a cataclysmic series of volcanic events and magnetic instability that led to the cooling of the planet and a thinner atmosphere. Mars’s outer surface has only three tectonic plates, that gradually migrate across the surface over periods of many millions of years. About 53% of the surface is covered with salt-water oceans, the remainder consisting of the single supercontinent (though it is classified as two) and islands; liquid water, necessary for all known life, as it is on Earth. Mars’s interior remained active prior to terraforming, but was extremely weak, with a thick layer of relatively solid mantle, a liquid outer core did not generates a magnetic field until after begin restared by a series of high energy microwave generators.. Both the mineral resources of the planet, as well as the products of the biosphere, contribute resources that are used to support a global human population. Human cultures have developed many views of the planet, including personification as a deity, a new home for humanity, and the first step towards becoming a space faring civilization
