New UArizona research finds that the target asteroid of NASA’s Psyche mission may not be as metallic or dense as previously predicted.

The widely studied metallic asteroid known as 16 Psyche was long thought to be the exposed iron core of a small planet that failed to form during the earliest days of the solar system. But new University of Arizona-led research suggests that the asteroid might not be as metallic or dense as once thought, and hints at a much different origin story.
Scientists are interested in 16 Psyche because if its presumed origins are true, it would provide an opportunity to study an exposed planetary core up close. NASA is scheduled to launch its Psyche mission in 2022 and arrive at the asteroid in 2026.
TUCSON, Ariz. (University of Arizona PR) — It’s 5 o’clock somewhere. And while here on Earth, “happy hour” is commonly associated with winding down and the optional cold beverage, that’s when things get going on Bennu, the destination asteroid of the University of Arizona-led OSIRIS-REx NASA mission.
NICE, France (ESA PR) — Queen guitarist and astrophysicist Brian May has teamed up with asteroid researchers to investigate striking similarities and a puzzling difference between separate bodies explored by space probes. The research team ran a supercomputer-based ‘fight club’ involving simulated large asteroid collisions to probe the objects’ likely origins. Their work is reported in Nature Communications.
