New findings on the chemical composition of hydrated soil at regional scales. Previous observations of soil observed along crater slopes on Mars showed a significant amount of perchlorate salts, which tend to be associated with brines with a moderate pH level...

Some dusty parts of Mars get as cold at night year-round as the planet’s poles do in winter, even regions near the equator in summer, according to new NASA findings based on Mars Reconnaissance Orbiter observations. The surface in these regions becomes so frigid overnight that an extremely thin layer of CO2 frost appears to form. The frost then vaporizes in the morning...
Read MoreSome of the wind-sculpted sand ripples on Mars are a type not seen on Earth, and their relationship to the thin Martian atmosphere today provides new clues about the atmosphere’s history. The determination that these mid-size ripples are a distinct type resulted from observations by NASA’s Curiosity Mars rover. 6 months ago, Curiosity made the first up-close study of active sand dunes anywhere other than Earth, at”Bagnold Dunes” on the NW flank of Mount Sharp.
“Earth and Mars both have big sand dunes and small sand ripples, but on Mars, there’s something in between that w...
Read MoreFuture Martian explorers might not need to leave the Earth to prepare themselves for life on the Red Planet. The Mars Society have built an analogue research site in Utah, USA, which simulates the conditions on our neighbouring planet. Practicing the methods needed to collect biological samples while wearing spacesuits, a team of Canadian scientists have studied the diverse local flora...
