Mars is basically a time capsule! Scientists just found evidence that giant chunks of ancient space debris—left over from epic collisions 4.5 billion years ago—are buried deep in the Martian mantle. Thanks to NASA’s InSight lander and its marsquake recordings, we now know Mars’ insides are studded with these cosmic leftovers. Unlike Earth, Mars doesn’t have tectonic plates to erase its past, so these fragments are still chilling down there. Wild, right? #Science #Mars #SpaceDiscovery
