NASA's robotic InSight lander for the first time detected seismic waves traveling along the Martian surface, as opposed to deeper in the body of the planet, caused by two space rocks striking Mars in September and December of last year. The reverberation of these waves along the surface gave clues about the crust, the planet's outermost layer, over a wide geographical expanse in the northern hemisphere.
