For the first time since landing on Mars in November, NASA’s InSight mission has recorded and measured what scientists believe to be a “marsquake.”
Martian winds have been recorded on the surface and can be heard on the recording released by the agency.
But then, a deeper sound emerges, recorded by the lander’s seismometer that was installed on the Red Planet’s surface in December.
It’s a seismic signal that was recorded April 6, and by all indications, the InSight team believes this sound is a quake from within the planet rather than something on the surface.
The InSight Twitter account shared the recording Tuesday: “Mars, I hear you. I’ve detected some quiet but distinct shakig on #Mars. The faint rumbles appear to have come from the inside of the planet, and are still being studied by my team. Take a listen.”
The data will continue to be studied so that scientists can be sure of the signal’s origin.
