This is the largest meteorite impact ever detected on a planet. NASA presented it on Thursday, October 27, during a highly anticipated press conference.
This is a major advance in the exploration of Mars, which is materialized by two discoveries. On the one hand, this enormous crater, formed by the fall of a meteorite, on December 24th. The collision caused chunks of ice buried in the ground to erupt all around the crater. The impact was detected by the French seismograph onboard NASA’s InSight module.
In orbit, the American probe, Reconnaissance, then located and photographed the crater. The ground module, the probe in orbit, also have areas of seismic activity, which upset what we thought we knew about Mars. This new discovery indicates that Mars is a living planet.
