Mineral jarosite found on Mars

g Stars - What is the potential habitability of the nearby star system Gl 117? See article.
g Abodes - The presence of the mineral jarosite on Mars means that liquid water had to exist at some point in the planet's past. Scientists have developed a new method for determining the age of jarosite and the conditions under which it formed. Now, scientists might be able to use jarosite samples to define when and where water flowed on Mars. See article.
g Cosmicus - In August 2012, a new Mars rover will be delivered to Gale Crater, where it will search for signs that Mars was once habitable for life. See article.
