This Week in Space 73: Heavy Metal in Space
Not all asteroids are created equal, and 16 Psyche, one of the largest, is extremely dense in metals, making it unique. Is the 140-mile giant the leftover core of a failed planet, or a more recent gravitational accretion of metal-rich bodies? Will it help us to understand how metallic cores—like Earth's—form and function? NASA's sending a spacecraft, also called Pysche, to find out. The mission is led by Dr. Lindy Elkins-Tanton, who joins Rod and bestselling author Daniel Suarez to explain what makes Psyche—both the asteroid and the mission—so fascinating.
