Curiosity rover spots ancient sea of Martian polygons - Popular Science

SYDNEY, Oct. 17 (Xinhua) -- An Australian study has produced the first comprehensive classification system and map of Martian soils, offering a framework to help scientists identify potential locations for future exploration, habitation and food production. The research classifies almost 800 million locations across Mars into a hierarchy of 2,000 soil classes using orbital observations and models, presenting a global map showing where they occur, according to a statement released by Australia's University of Sydney. "Scientists have mapped Mars' geology, mineralogy and chemistry before, but our system brings together multiple properties into a single framework, helping us understand how different Martian soils relate to one another and where they're found," said Daniel Irving, a PhD student at the university, who led the research. The classification system groups Martian soils into 10 major "realms," 100 "assemblages" and 2,000 detailed "forms" based on properties including texture, mineralogy, pH and profile thickness. As a proof of concept, researchers assessed the soil classes for characteristics relevant to plant production.

A pioneering mission to study a pair of Martian moons and return a 10-gram soil sample to Earth is being prepared for launch Oct. 19 from Japan’s Tanegashima Space Center. If successful, the Martian Moons Exploration (MMX) mission will add the first samples of Martian real estate to the world’s...

Three helicopters NASA is preparing to send to Mars will be able to fly hundreds of kilometers across the planet. The data they collect should help prepare for human landings. Scientists are getting ready to select the location where the helicopters will begin their work. Their focus is on plains that may contain deposits of frozen water beneath the surface.
