Mars’ climate is a tale of two planets. Evidence suggests a warm and wet early Mars. A thicker atmosphere, likely rich in carbon dioxide, trapped heat and allowed liquid water to flow, carving river valleys and potentially vast oceans. This era may have been fueled by volcanic eruptions or a stronger sun.
Over billions of years, Mars lost its magnetic field, leaving it vulnerable to solar wind stripping away the atmosphere. The planet turned frigid and dry, with remaining water locked as ice caps or underground. The thin atmosphere now allows dramatic temperature swings and dust storms.
The sculpted surface reflects this history. Cratered plains hint at heavy bombardment early on. Dried-up riverbeds and lakebeds are ghostly reminders of a watery past. Volcanic giants like Olympus Mons tower over the landscape, a testament to past activity that may have influenced Mars’ climate.
