Perseverance rover finds evidence of ancient floods on Mars, researchers say

The Perseverance rover, which spent months traveling to Mars, could hardly have landed in a more interesting spot. The Jezero crater — a dry, wind-scoured patch of Martian rock where the rover touched down in February — was once a lake bed fed by an ancient river with floods so powerful they could move boulders, scientists say. Those findings, published last week in the journal Science, confirmed scientists’ suspicions that the crater contained a lake millions of years ago, and also suggests that this part of Mars had a warm, humid past with a more complicated water cycle than was known. “There were rushing rivers here,” Katie Stack Morgan, a deputy project scientist of the Mars 2020 project and an author of the paper, said of Jezero’s landscape some 3.5 …
