What's Happening?
NASA's InSight mission has provided new insights into Mars' geological history by revealing debris from ancient impacts scattered within the planet's mantle. The InSight lander, equipped with a seismometer, recorded 1,319 marsquakes before its power depletion in 2022. These seismic activities have allowed scientists to study Mars' interior, including its crust, mantle, and core. The debris, consisting of lumps up to 2.5 miles across, offers a preserved geologic record due to Mars' lack of tectonic activity, which prevents the churning of its interior.

Why It's Important?
The findings from the InSight mission are crucial for understanding Mars' geological history and its differences from Earth. The preservation of impact debris in Mars' mantle provides a unique opportunity to study planetary formation and evolution without the interference of tectonic activity. This research enhances our knowledge of planetary science and could inform future exploration missions. The data gathered by InSight contributes to the broader understanding of seismic activity on Mars, aiding in the development of models for planetary interiors.
