New research shows that Mars did not dry up all at once
LOS ALAMOS, N.M., April 8, 2021 While attention has been focused on the Perseverance rover that landed on Mars last month, its predecessor Curiosity continues to explore the base of Mount Sharp on the red planet and is still making discoveries. Research published today in the journal Geology shows that Mars had drier and wetter eras before drying up completely about 3 billion years ago.
“A primary goal of the Curiosity mission was to study the transition between the habitable environment of the past, to the dry and cold climate that Mars has now. These rock layers recorded that change in great detail,” said Roger Wiens, a coauthor on the paper and scientist at Los Alamos National Laboratory, where he is on the ChemCam team. ChemCam is the rock-vaporizing laser that sits on the mast of the Curiosity rover and analyzes the chemical composition of martian rocks.
