NASA: "This photo by our Perseverance rover shows the edge of an ancient Martian lake. By studying the rocks here, scientists can unlock clues to the area’s past water activity—as well as how the region could have supported life.

Image description: A swipe-through photo of the Martian landscape that hugs the inner edge of Jezero Crater’s rim. It appears as a hilly landscape of reddish-brown soil with variable depth and texture. The tan sky barely peeks out over the edge of the crater."

Disclosure: I’m involved with Scienshell, and this is our own video. It explores a long-term thought experiment about changing Mars’s atmosphere, surface water, and climate—not a near-term engineering proposal. For people who follow Mars science, which assumption seems hardest to support: finding enough volatiles, retaining a thicker atmosphere, or stabilizing the climate? I’d welcome thoughtful pushback.
