Evidence of ancient lake sediments at the base of Mars' Jezero Crater offer new hope for finding traces of life in samples collected by NASA's Perseverance rover.
Perseverance touched down on Feb. 18, 2021 inside the Red Planet's 28-mile-wide (45 kilometers) Jezero Crater, which is believed to have once hosted a large lake and river delta. The rover has been scouring the crater in search of signs of past life and collecting and caching dozens of samples along the way for a possible future return to Earth.
