NASA's "InSight" probe probably recorded Marsh's "tremor" for the first time

Los Angeles (APA / AP) – NASA's "InSight" probe, installed on Mars since November, probably picked up the first sounds of an earthquake on the red planet. The weak audio signal was recorded on April 6, and therefore the 128th day of the robot on the planet, announced Tuesday the US Space Agency (local time).

The jolts picked up by the seismic probe instrument seem to be coming from inside Mars rather than wind forces on its surface, he said. Scientists are always busy exploring the exact cause of the signal, according to NASA.

However, the experts have already mentioned a milestone confirming the seismic activity of Mars. "Until now, we've collected background noise, but this event marks the official start of a new field of research: earthquake science on Mars!" Said Bruce Banerdt, InSight expert. "We have been waiting for a signal of this type for months," said Philippe Lognonne, Earthquake Specialist at the French Institute of Physics of the Globe of Paris (IPGP). "It's so exciting to finally have proof that Mars is still seismically active."

With many scientific instruments, "InSight" will spend at least two years exploring the interior of Mars and learning more about its structure and dynamics beneath its surface. "InSight" is a 360 kg robot that does not roll but stays in the same place. In December, two sensors from the probe, according to NASA, would have captured wind noise on the red planet. The "InSight" mission costs around 650 million euros.
