Scientists peer within Mars to measure layers of Pink Planet

Marsquakes recorded by NASA’s InSight mission offer the first direct evidence of key boundaries in the Martian interior, which could help planetary scientists understand how rocky planets are formed, a new study suggests.

The spacecraft landed at Elysium Planitia in November 2018 on a quest to probe the poorly understood interior of Mars. The thickness of the Red Planet crust and the depth of its core, for example, had only been estimated with models before. InSight allows researchers to check their models for the first time.
