NASA is reporting its first evidence of a marsquake.
The InSight lander recorded a gentle rumble on Mars on April 6th.
They determined the rumble was a quake from within the Red Planet. Scientist Philippe Lognonne said he was excited to finally have proof of seismic activity on Mars.
That planet is similar to the moon in that it does not have tectonic plates. Because of that, it's not as geologically active as Earth.
NASA posted the gentle rumble recording on its Twitter page.
