UNLV Research Suggests A Wetter Mars
New UNLV research published in Nature Communications suggests Mars may have had more water than previously thought. Scientists use meteorites to judge water contents on planets like Mars, and for the study they subjected a hydrogen-rich mineral, whitlockite, to shock levels common in meteorites. The shock dehydrated the mineral into the waterless merrillite, a mineral common on the Red Planet. If the dry merrillite had once existed on Mars as the hydrated whitlockite, it could mean more water in the planet’s history.
