On April 6, NASA’s InSight lander sensed its first confirmed marsquake, a phenomenon scientists suspected, but couldn’t confirm, occurred on the neighboring planet. Measuring the Martian equivalent of earthquakes, seismic waves traveling through the interior of the planet, was among the lander’s key science goals.

„We’ve been waiting months for our first marsquake,“ Philippe Lognonné, the principal investigator for the seismometer instrument, said in a statement released by the French space agency, which runs the instrument with the national research center. „It’s so exciting to finally have proof that Mars is still seismically active.“
