Huge chunks of ancient cosmic objects may be stuck inside Mars
Instead of neat, layered structures resembling a smooth slice of Millionaire’s Shortbread, Mars’ mantle is more like a rocky road brownie — chunky, uneven, and filled with ancient debris from its violent beginnings.
NASA InSight Uncovers Ancient Protoplanet Remnants in Mars’ Mantle
New data from NASA’s retired InSight lander is rewriting our understanding of Mars’ violent early history, revealing that the Red Planet may harbor massive remnants of ancient cosmic collisions deep within its mantle. Researchers analyzing seismic readings from the mission have identified dense anomalies buried hundreds of miles beneath the Martian surface, suggesting these could be chunks of protoplanets—embryonic worlds that smashed into Mars …
The finding was reported on Thursday, August 28, in a study published by Science magazine The rocky material that impacted Mars is scattered into gigantic pieces along the mantle of the planet, offering clues about the interior of Mars and its ancient past. What appear to be fragments of the aftermath of the massive impacts on Mars that occurred 4.5 billion years ago have been detected in the depths of the planet. The discovery was made thanks t…
