NASA’s InSight lander recorded a magnitude 4 marsquake final Dec. 24, however scientists discovered solely later the reason for that quake: a meteoroid strike estimated to be one of many greatest seen on Mars since NASA started exploring the cosmos. What’s extra, the meteoroid excavated boulder-size chunks of ice buried nearer to the Martian equator than ever discovered earlier than — a discovery with implications for NASA’s future plans to ship astronauts to the Pink Planet.
