In a new study, planetary researchers used global and high-resolution orbital imaging to discover a fresh, 21.5-m (71-foot) impact crater that appeared at the same time as one of the marsquakes detected by NASA’s InSight lander; this means the seismometer detected a meteoroid strike rather than geological activity within the planet. In an associated study, they scanned through a large amount of orbital image data and identified 123 impact craters that formed between December 2018 and December 2022, 49 of which might also have been recorded by the NASA InSight lander’s seismometer.
