NASA listens how Mars's "heart" vibrates to discover the secrets of its origins – 12/20/2018



The InSight probe, which develops a historical mission on Mars, successfully implemented the martian surface a hypersensitive French seismometer, an important instrument for continuing its scientific mission, NASA announced this Thursday.

This unit, worth tens of thousands of millions and designed by the French agency CNES, serves listen to the vibrations in the interior of the red planet and discover more about the story of their formation.

"Use of the seismometer is as important as the landing of InSight on Mars", the researcher declared responsible for the mission at NASA, Bruce Banerdt.

"It's the most important tool in InSight: we need it to achieve at least, three quarters of our scientific goals"he added.

The probe deposited the seismometer with its robot arm, about 1.64 meters in front of it, according to the US space carrier.

The instrument, called SEIS (seismic experiment for internal structure, seismic experiment for internal structure) you will hear the earth's smallest vibrations, mainly due to meteorochok waves and earthquakes.

These waves will allow for tracking the first three-dimensional map of Mars's interior, which will enable us to better understand the formation of billions of years ago by the so-called "red planet".

"Having this seismometer on earth is like having a phone near the ear"explained French geophysicist Philippe Lognonné, researcher at the Institute de Physique du Globe in Paris and father of this precious instrument.

The InSight probe, valued at $ 993 million, arrived in March on November 26th.
