NASA is about to begin building its latest spacecraft. Called “Psyche” it will explore a 140 miles/226 kilometers-wide asteroid called “16 Psyche.” Today it’s passed a major milestone.
Why is NASA going to ‘16 Psyche?’
Located in the Solar System’s main asteroid belt between Mars and Jupiter, metal-rich 16 Psyche is thought to be the exposed metallic iron, nickel and gold core of a protoplanet. Most asteroids are rocky or icy.
