From the Ted Talk by Linda T. Elkins-Tanton: Why is NASA sending a spacecraft to a metal world?

Unscramble the Blue Letters


To do that, NASA’s robotic orbiter will be equipped with an aarry of advanced instruments. A spectrometer will analyze the gmmaa rays and neutrons produced when Psyche is scrtuk by cosmic rays. Each eemlnet in the periodic table releases gamma rays of specific wavelengths, so these measurements will tell us what elements are found on the surface. A mteemogtenar will measure Psyche’s magnetic field, allowing us to learn more about how Earth’s magnetic fleid is generated at its core. And of course, an imager will give us a closer look at the surface than ever before.

Visiting a whole new kind of world is exciting enough on its own. But the mission to Psyche gives us a unique cacnhe to decvisor our own planet’s innermost secrets in an orbit far, far away.
