Mars: World That Never Was
Mars once had rivers, lakes, and a thicker atmosphere, conditions closer to early Earth than the frozen desert visible today. This film asks what happened to that early, wetter Mars and whether the conditions that may have let life arise there ever actually produced it. Planetary scientists walk through the evidence from orbiters and landers: dry riverbeds, mineral deposits that only form in liquid water, and the polar ice caps that still hold frozen reserves. The film considers where any surviving life might be hiding now, whether under the ice caps, in underground aquifers, or in pockets of soil shielded from radiation and the thin, dry surface air. It weighs the case for a Mars that briefly resembled Earth against the harsher likelihood that the planet never crossed the threshold into life at all. The tone stays speculative rather than conclusive, treating the search for a second genesis as an open scientific question rather than a settled discovery.
