A seismometer built by the Institut de Physique du Globe de Paris and the space optics specialists Sodern has recorded a monster quake on Mars, the largest ever measured on the red planet.
The instrument, called Seismic Experiment for Interior Structure, which is part of NASA's InSight mission on Mars, recorded the 4.7 magnitude quake at a distance of 2250 km from its epicentre. The latest 'Marsquake' beat the mission's previous record of a 4.2 which was measured in August 2021.
