Psyche ( SY-kee) is a NASA Discovery Program space mission launched on October 13, 2023, to explore the origin of planetary cores by orbiting and studying the metallic asteroid 16 Psyche beginning in 2029. NASA's Jet Propulsion Laboratory (JPL) manages the project.
The spacecraft will not land on the asteroid, but will orbit it from August 5, 2029, to October 31, 2031, spending 817 days in orbit. Psyche uses solar-powered Hall-effect thrusters for propulsion and orbital maneuvering, the first interplanetary spacecraft to use that technology. It's also the first mission to use laser optical communications beyond the Earth-Moon system.
Asteroid 16 Psyche is the heaviest known M-type asteroid, and may be an exposed iron core of a protoplanet, the remnant of a violent collision with another object that stripped off its mantle and crust. On January 4, 2017, the Psyche mission was selected for NASA's Discovery #14 mission.
