The seismic data of NASA's InSight mission reveal that Mars once housed huge pockets of magma interconnected under its crust — a type of magmatism that was believed to be Earth's own. This discovery, published in Nature Astronomy, discusses the maps of Martian geology and its implications for past habitability from [...]
Mars ran Earth-like magma systems for billions of years without plate tectonics
Twenty-four kilometers beneath the surface of Mars, seismic waves from ancient marsquakes have revealed something that should not be there: a chemical boundary that marks where vast pools of molten rock once separated into layers, exactly as they do inside Earth’s active volcanic systems. Mars has no plate tectonics. It has no active volcanoes. Its crust should be a simple, undifferentiated cap on a cooling interior. Instead, it carries the reco…
