NASA has announced that its InSight lander detected what’s probably an earthquake on the planet Mars. What was nicknamed marsquake is a small earthquake that on Earth would be recorded with a magnitude of 2-2.5 and it’s only thanks to an instrument called SEIS designed for that purpose that it was detected on Mars on April 6, 2019. We’re at the beginning of Martian seismology therefore the data will be studied to confirm that it was indeed an earthquake and if that’s the case it will be the first one.
