Areography, also known as the geography of Mars, is a subfield of planetary science that entails the delineation and characterization of regions on Mars. [ 1 ] [ 2 ] [ 3 ] Areography is mainly focused on what is called physical geography on Earth; that is the distribution of physical features across Mars and their cartographic representations.
The Aerial Regional-scale Environmental Survey (ARES) was a proposal by NASA's Langley Research Center to build a robotic, rocket-powered airplane that would fly one mile above the surface of Mars, [1] in order to investigate the atmosphere, surface, and sub-surface of the planet.
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.
The mission was led by Project Manager Peter Theisinger of NASA's Jet Propulsion Laboratory and Principal Investigator Steven Squyres, professor of astronomy at Cornell University. Primary among the mission's scientific goals is to search for and characterize a wide range of rocks and soils that hold clues to past water activity on Mars.
Artist's conception of the process of terraforming Mars.. The terraforming of Mars or the terraformation of Mars is a hypothetical procedure that would consist of a planetary engineering project or concurrent projects aspiring to transform Mars from a planet hostile to terrestrial life to one that could sustainably host humans and other lifeforms free of protection or mediation.
It is used in planetary geology for the naming of landform features on other planets, including what could be old river valleys that were discovered on Mars, when probes were first sent to Mars. The Viking Orbiters caused a revolution in our ideas about water on Mars ; huge river valleys were found in many areas.
The following is a list of regions on Mars given the name Terra (pl. Terrae). Most cover large, rugged areas, often including outflow channels , cratering, and " chaos terrain ". They may be contrasted with the Planitia (e.g., Amazonis Planitia ) and Mare (e.g., Mare Erythraeum ), smoother regions of differing albedo .
The Mars Society Germany proposed a crewed Mars mission using several launches of a heavy-lift rocket derived from the Ariane 5. Roughly five launches would be required to send a crew of five on a 1200-day mission, with a payload of 120,000 kg (260,000 lb). Total project cost was estimated to be 10 to 15 billion euros. [110]
