science π₯ Mars's South is way hotter inside than the North
An international team of scientists published new findings in Nature about Mars's internal heat distribution. They analyzed archival data from NASA's Mars Global Surveyor, Mars Odyssey, and Mars Reconnaissance Orbiter. Researchers found the southern hemisphere has an interior temperature 200-400Β°C hotter than the northern hemisphere. This suggests the thicker southern highlands might be insulated from cooling over billions of years. Future gravity data will help reveal the planet's 3D interior structure. πͺ
