NASA's Perseverance rover switches to science investigator in a search for signs of life

NASA's Perseverance rover has switched from photographing the Ingenuity helicopter's test flights, to searching for signs of long gone Martian life. The US space agency confirmed that the SUV-sized rover has started to test the ancient lakebed in the Jezero crater by focusing its science instruments on rocks. A camera called WATSON on the end of the rover's robotic arm has taken detailed shots of the rocks, with extra data coming from a pair of zoomable cameras. The Perseverance team tweeted: 'The time has come: I'm switching from on-scene photographer to science investigator. Did this ancient lakebed ever have life? The tools I brought will help begin the hunt.
