A recent study, based on climate models and geological data from space missions, posits that Mars had extended periods with temperate and humid conditions. Evidence of ancient rivers and lakes points to the stable presence of liquid water on the surface, reinforcing the idea of a climate more similar to that of primitive Earth before the planet lost its dense atmosphere.
Climate modeling and geology: the keys to reconstructing primitive Mars 🔍
The research combines 3D climate simulations with observations from orbiters and rovers on mineral composition and terrain formations. The models incorporate a dense CO2 atmosphere, ancient topography, and greater orbital obliquity. This allows simulating hydrological cycles that explain the observed valley networks and sedimentary deposits, indicating that water flowed persistently, not just in isolated events.
A Mars with beaches? Too bad they forgot to maintain the atmosphere 😅
So it turns out Mars may have had its own lakes and perhaps even a sea. A perfect spot for a second home, if we ignore the lack of oxygen and radiation. It's as if the planet did all the hard work of creating a potentially habitable environment and then, due to a cosmic oversight, let its atmosphere escape into space. A clear case of poor planetary management. Now we're left with photos of dry riverbeds and the bill for sending rovers to check it out.
