Mars' Valles Marineris shows seismic activity, hinting at internal dynamics

Analysis of a Marsquake recorded five years ago by NASA's InSight lander reveals seismic waves originating from beneath Valles Marineris, the solar system's largest canyon. This suggests ongoing geological activity within Mars, challenging the notion that the planet is geologically dead. The finding has implications for understanding Martian interior structure and evolution.
