Listen to the first marsquake ever recorded: NASA’s InSight lander detects likely tremor on the red planet in what could finally be ‘proof that Mars is still seismically active’

A robot stationed on the red planet has, for the first time, detected what’s thought to be a ‘marsquake.’

NASA’s InSight lander has been listening for faint rumbles beneath the surface since December, when it placed its seismometer down to begin the groundbreaking mission.

In what scientists have hailed an ‘exciting’ milestone, the InSight team says the lander measured and recorded a seismic signal on April 6, its 128th Martian day, using its Seismic Experiment for Interior Structure (SEIS) instrument.

While other disturbances have been recorded, previous signals are thought to have been caused by activity above the surface, such as wind.

The suspected marsquake, however, dubbed the Martian sol 128 event, appears to have originated from within the depths.

InSight’s efforts build upon work laid by the Apollo astronauts on the moon during the late 1960s and 70s, which first revealed clues on lunar seismic activity and the interior of the moon.
