NASA's InSight satellite placed its first instrument on the surface of Mars this Wednesday (19), just weeks after landing on the planet, completing "an important task" of the mission, reports the website. from the agency.
This is a seismograph designed to detect telluric movements and meteorite impacts on the red planet. The device was installed using a shell that InSight has in its bionic arms.
"Placing the seismograph on the ground is an incredible Christmas present," said Tom Hoffman, Project Manager, Propulsion Laboratory,
In case you missed it, here's a for the history books: for the very first time, I placed a seismometer on the surface of #March ! Once everything is set up, I can start listening to marsquakes. More information: https://t.co/GYNO4txPPi pic.twitter.com/vUkedVMcTX

If you missed Here is one thing for the story books: for the first time, I put a seismograph on the surface of Mars! When everything is finished, I can start listening to the "Marshals".
"This is InSight's highest priority tool: we need to deliver it, about three-quarters of our science goals," said lead researcher Bruce. Banerdt.
This device allows scientists to learn more about the Martian subsoil by studying their movements. Each earthquake acts as a sort of "lightning" that illuminates the inner structure of the planet. By badyzing the way in which seismic waves cross the inner layers of the planet, scientists can discover the depth and composition of each of them, explain the experts.
