NASA’s Psyche spacecraft used Mars as a gravitational slingshot during a precision flyby in May 2026, gaining velocity toward the metal-rich asteroid Psyche after launching on a solar electric propulsion trajectory years earlier.
Mission controllers at Jet Propulsion Laboratory adjusted navigation using Mars’s gravity to shorten travel time and refine approach angles for the main belt target believed composed largely of iron and nickel. The flyby provided engineering tests of instruments and telecommunications at interplanetary distances.
Psyche aims to explore a planetary core-like body that may reveal clues about early solar system formation and planetary differentiation processes. Scientists hypothesize the asteroid is exposed core material from a failed protoplanet collision.
The Mars assist maneuver conserved fuel aboard the solar-powered probe, which uses ion thrusters for gradual acceleration. Images captured during flyby will support public outreach and calibrate camera systems before arrival at Psyche in later mission phases.
NASA highlighted the event alongside other robotic exploration milestones during a week when China launched crewed missions and commercial lunar landers continued development. Independent astronomers tracked the spacecraft trajectory via Doppler data shared in navigation blogs.
Psyche remains on schedule according to mission managers barring unexpected technical anomalies.
Mission engineers said telemetry from the Mars flyby will guide final trajectory corrections before Psyche reaches its asteroid destination in the outer main belt later this decade.
