It turned out that Mars was not as quiet as first thought. Instead, there is intense seismic activity on the red planet, which rumbles and groans.
The planet is experiencing dynamic shocks far below its surface, and molten lava may be spilling just beneath the Martian crust right now. If true, it will alter our knowledge of Martian geodynamics that we have accumulated over the years and imply that volcanic activity on the red planet is not only feasible but ongoing, and is occurring more frequently than anticipated.
What does this noise mean, however? How will it alter the way we view Martian geology? Finally, and most significantly, how will this revolutionary finding affect our efforts to find past and contemporary Martian life?
