Mars meteorite collisions happen too often. The two distant collisions they identified from the data were the two largest collisions ever detected by scientists, even after decades of observations from orbit. Previously, new impacts on Mars were spotted using before-and-after images taken by cameras in orbit around the planet. To determine exactly when and where collisions occurred on Mars, Daubar and a team of researchers analyzed InSight’s seismic signals, then compared that seismic data to images taken by NASA’s Mars Reconnaissance Orbiter. This dual approach — using seismic data and orbital images — allowed them to confirm that the seismic signals were caused by collisions and cross-check their findings for accuracy.
