The InSight probe, which arrived to Mars last month, successfully set up an excessive seismometer on Martian surface, a key instrument for continuing its scientific mission, NASA announced on Thursday.
This device, worth ten million euros and designed by the French CNES agency, listens to listen to the vibrations of the interior of the red planet and reveals more about the history of its formation.
"The development of a seismometer is just as important as the landing of InSight on Mars," said Bruce Banerdt, mission scientist at NASA.
"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.
The instrument, called SEIS (Seismic Internal Structure Experiment, Seismic Experiment for the Internal Structure), exhibits the smallest soil vibration, mainly caused by waves of meteor shock and earthquakes.
These waves will allow the creation of the first three-dimensional map of the interior of Mars, which will enable us to better understand the formation of the so-called. "The Red Planets" billions of years ago.
"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, arrived on Mars on November 26th.
