Forbes contributor David Bressan writes that a new study co-authored by MIT researchers finds that images taken by the Perseverance rover show that Mars’ Jezero crater was once a lake. “The fine-grained clay and carbonate layers deposited in the fossil lake are capped by a diamict, a sedimentary rock consisting of a mix of large and small boulders,” writes Bressan. “Scientists think the boulders were picked up tens of miles upstream and deposited into the former lakebed by episodic flash floods, suggesting a catastrophic climate change in Mars' distant past.”
