Psyche uses Mars as a gravity boost on its way to a metal-rich asteroid

TL;DR Summary
NASA's Psyche spacecraft flew by Mars on May 15, 2026 to perform a gravity assist, gaining speed and reshaping its path toward the metal-rich asteroid 16 Psyche. The flyby occurred about 2,800 miles from Mars at roughly 12,333 mph and saves propellant by using the planet's gravity, helping the mission stay on track to reach 16 Psyche in July 2029, while continuing to rely on solar-electric propulsion for gradual thrust.
