Solar System's Largest Canyon Still Tectonically Active
Original: The Largest Canyon in the Solar System is Still Tectonically Active
New reporting highlights that Valles Marineris, the vast canyon system on Mars, shows signs of ongoing tectonic activity. Stretching thousands of kilometers and dwarfing Earth's Grand Canyon, the chasm appears far from geologically dead. The finding adds to growing evidence that Mars retains internal dynamics, challenging assumptions that the planet's geological activity ended billions of years ago.
Why now: New research suggesting Mars is still geologically active contradicts the long-held view that the planet is dead inside.
