Aeolis Palus December 9, 2013, NASA reported that, based on evidence from "Curiosity" studying Aeolis Palus, Gale Crater contained an ancient freshwater lake which could have been a hospitable environment for microbial life. On December 16, 2014, NASA reported detecting, based on measurements by the "Curiosity" rover, an unusual increase, then decrease, in the amounts of methane in the atmosphere of the planet Mars; in addition, organic chemicals were detected in powder drilled from a rock by the "Curiosity" rover. Also, based on deuterium to hydrogen ratio studies, much of the water at Gale Crater on Mars was found to have been
NASA Human Exploration Rover Challenge NASA Human Exploration Rover Challenge The NASA Human Exploration Rover Challenge, prior to 2014 referred to as the Great Moonbuggy Race, is an annual competition for high school and college students to design, build, and race human-powered, collapsible vehicles over simulated lunar/Martian terrain. NASA sponsors the competition, first held in 1994, and, since 1996, the U.S. Space & Rocket Center hosts. Students created vehicles dubbed "moonbuggies" to face challenges similar to those engineers at NASA's Marshall Space Flight Center addressed in preparation for Apollo 15. On that mission, on July 31, 1971, the first Lunar Roving Vehicle extended the range
