The InSight probe, which arrived to Mars last month, successfully deployed the Martian surface oversensitive seismometer of French production, a key instrument for continuing its scientific mission, NASA announced on Thursday.

This device, worth tens of millions of euros and designed by the French CNES agency, serves Listen to the vibrations of the interior of the red planet and discover more about the history of its formation.

"Seismometer schedule is just as important as the landing of InSight on Mars"said a scientist responsible for the NASA mission, Bruce Banerdt.

"This is the most important instrument of InSight: we need to achieve at least three quarters of our scientific goals," he added.

The probe has deposited a seismometer with a robotic arm, about 1.44 meters ahead of it, according to the US space agency.

"After a long day, I did it: I put my seismometer on the surface of Mars! With SIX I will be able to hear vibrations and help discover the heart attack of Mars", published a Twitter probe bill.

The instrument, called SEIS (Seismic Experiment for Internal Structure, Seismic Experiment for Internal Structure) you hear the smallest vibration of the ground, which is mainly caused by waves of meteor shock and earthquakes.

These waves will allow the drawing of the first three-dimensional map of the interior of Mars, which is will enable a better understanding of the formation, billions of years ago, so-called. "Red Planets".

"Having this seismometer on the ground is like having a phone near your ear," explains French geophysicist Philippe Lognonne, a researcher at the de Phisikue du Globe Institute in Paris, and father of this precious instrument.

The InSight probe, worth 993 million dollars, He arrived on Mars on November 26th.
