SpaceX and NASA are looking to land a ship at one of these 4 places on Mars

As part of their effort to kick-start the eventual colonization of Mars, SpaceX is sending an unmanned Dragon spacecraft to Mars. Initially, that mission was set for 2018, but is now re-scheduled for 2020. Now, SpaceX says they're working with NASA to select a suitable landing site for their first Dragon mission to Mars.At a presentation in Texas on March 18th, Paul Wooster of SpaceX said that they have been working with scientists at NASA's Jet Propulsion Laboratory (JPL) to identify candidate landing sites on the surface of Mars. In order to aid colonization, the sites need to be:near the equator, for solar powernear large quantities of ice, for waterat low elevation, for better thermal conditionsBut finding a site that meets those conditions is difficult.According to SpaceNews, the study done with NASA initially recognized 4 regions in Mars' northern hemisphere, all within 40 degrees of the equator. They are Deuteronilus Mensae, Phlegra Montes, Utopia Planitia, and Arcadia Planitia.SEE ALSO:Everybody's flying to the moonDeuteronilus MensaeDeuteronilus Mensae (DM) is located between older, cratered highlands and low plains. DM shows evidence of glacial activity in its surface features. In fact, there are still glaciers there, which makes it a desirable source of ice.Phlegra MontesPhlegra Montes (PM) is a system of mountains on the Martian surface, over 1300 km across. Its a complex system of basins, hills, and ridges. They are likely tectonic in origin, rather than volcanic, and the region probably contains large quantities of water ice, perhaps 20 meters below the surface.Utopia PlanitiaUtopia Planitia (UP) is the region where the Viking 2 lander set down in 1976. At 3300 km in diameter, UP is the largest impact basin in the Solar System. In 2016, NASA found a huge deposit of underground ice there. The water is estimated to be the same volume as Lake Superior.See the rest of the story at Business Insider
