Psyche is a NASA interplanetary mission to visit the main belt asteroid of the same name, 16 Psyche. Spacecraft will take 4 years and one Mars flyby to reach the asteroid, which is of particular interest due to being comprised mostly of iron and nickel. Psyche is theorized to be a remnant of an early planet's core, and may offer insights into how solar system formed and evolved. The mission is led by Arizona State University, with NASA JPL being responsible for mission management and operations.
