Perseverance Mission Highlights CRISM’s Continued Contributions to Martian Science By Michael Buckley On ancient Mars, water carved channels and transported sediments to form fans and deltas within lake basins. Examination of spectral data acquired from orbit shows that some of these sediments have minerals that indicate chemical alteration by water. In the Jezero crater delta, above, sediments contain clays and carbonates.
