TED-ED: Why is NASA sending a spacecraft to a metal world? - Linda T. Elkins-Tanton

The video discusses the asteroid 16 Psyche, a metallic body in the solar system, and NASA's mission to study it. Psyche is unique due to its nickel-iron composition, similar to Earth's core, offering a rare opportunity to study planetary formation and core composition. NASA's mission, part of the Discovery Program, aims to explore Psyche using advanced instruments to analyze its surface and magnetic field. This mission could provide insights into Earth's innermost secrets by studying an exposed metallic core in space.
