Mars' Core Reveals a Rocky Road, Not Millionaire's Shortbread
New Insights into the Interior of Mars A groundbreaking study has provided a detailed look at the inner structure of Mars, revealing a complex and chaotic composition that defies previous assumptions. Scientists have likened this internal structure to a Rocky Road candy, with various layers and fragments intermingled rather than neatly stacked. Previously, it was believed that the planet's crust, mantle, and core were arranged in a uniform manner, similar to the layers of a Millionaire’s Shortbread. However, data from NASA's InSight mission has challenged this view, showing that the Martian mantle is far more disorganized. Researchers from Imperial College London have found that the interior contains large rock fragments, up to 2.5 miles (4km) wide, scattered throughout like marshmallows and biscuit pieces in a Rocky Road. These ancient fragments are described as "geological fossils" from Mars' violent early history. The planet formed about 4.5 billion years ag...
