NASA Studying 4 Landing Site Options for 2016 Mars Mission - Authint Mail

NASA is weighing candidate landing sites for its next mission to the surface of Mars, a three-legged probe that will study the Red Planet's core in 2016. The space agency has four potential landing sites in mind for the new InSight Mars lander. The spacecraft is slated to launch in March 2016 and land on the Red Planet six months later. "We picked four sites that look safest," geologist Matt Golombek of NASA's Jet Propulsion Laboratory in Pasadena, Calif., said in a statement. "They have mostly smooth terrain, few rocks and very little slope." NASA's InSight mission is a $425 million expedition to determine if the core of Mars is liquid or solid, and why the planet's crust appears to lack tectonic plates like those found on Earth. The probe's name is short for Interior Exploration Using Seismic Investigations, Geodesy and Heat Transport. Golombek is leading NASA's site-selection process for the Mars InSight mission. Each of the four potential InSight landing sites is near one another in an area of the equatorial region of Mars called Elysium Planitia. On a NASA-issued map, the InSight landing site candidates appear to be clustered in a zone north of Gale Crater  where the huge Curiosity rover landed in 2012  and to the northwest of Gusev Crater, where the smaller Spirit rover landed in 2004. NASA will now use its powerful Mars Reconnaissance Orbiter in orbit around the Red Planet to further study the potential landing sites and eventually make a final decision. "This mission's science goals are not related to any specific location on Mars because we're studying the planet as a whole, down to its core," the mission's principal investigator, Bruce Banerdt of JPL, said in a statement. "Mission safety and survival are what drive our criteria for a landing site." The Elysium Planitia region of Mars was chosen because it promises the best chances of success for InSight's mission to probe the interior of Mars, NASA officials said. InSight is equipped with a heat-flow probe, which it will hammer into the surface of Mars to a depth of between 9 and 15 feet (2.7 to 4.5 meters). But the probe can only hammer into Martian dirt and broken-up surface material, not hard bedrock. InSight also carries a seismometer and radio to conduct experiments. Scientists hope the mission will help them better understand how rocky planets form. "For this mission, we needed to look below the surface to evaluate candidate landing sites," Golombek said. InSight also needs a landing site near the Mars equator to ensure there will be enough sunlight for its solar arrays throughout the Martian year. The landing site must be covered with an atmosphere thick enough to support via Science - Google News http://news.google.com/news/url?sa=t&fd=R&usg=AFQjCNGpx1N0gR1NyfDgbVXneS3oSAfsgQ&url=http://www.authintmail.com/news/science/nasa-studying-4-landing-site-options-2016-mars-mission
