A newly completed analysis of Perseverance’s first images from Mars finds that the landing site, Jezero Crater, was really a lake that was fed by a river, with sedimentary layers, flash floods, and strewn boulders. Plus, Central African biomass burning, Arctic permafrost melting, and we look at jewelry that celebrates upcoming missions.
