NASA's Psyche spacecraft performed a gravity-assist maneuver around Mars on Friday, May 15, 2026 [1], to shift its trajectory toward a rare-metal asteroid.

This slingshot maneuver is critical for the mission's success because it allows the spacecraft to reach its destination more efficiently. By utilizing the gravitational pull of Mars, NASA can adjust the probe's path more quickly and cheaply than using onboard fuel alone.

The target of the mission is the asteroid Psyche, located in the main asteroid belt. Unlike most asteroids, which are composed of rock or ice, Psyche is believed to be primarily metallic. Scientists hope that studying this unique body will provide a direct look at the kind of material that forms the cores of terrestrial planets.

"The crucial manoeuvre scheduled for Friday will use the gravity of Mars to shift Psyche onto the right path, a faster and cheaper method NASA scientists say could help unlock clues about the birth of Earth," NASA scientists said [1].

The flyby serves a dual purpose by providing an opportunity to gather additional data during the transit. This information may help researchers better understand the early processes that shaped the solar system, and the specific conditions that led to the formation of Earth.

"NASA's Psyche spacecraft will slingshot past Mars on Friday, on its way toward a rare metal‑rich asteroid," the NASA press office said [2].

The spacecraft will continue its journey through the asteroid belt after departing the vicinity of Mars. The mission represents a significant step in planetary science, as it targets a celestial body that is fundamentally different from the rocky asteroids previously studied in detail.

“The spacecraft used a gravity-assist maneuver on Friday to adjust its trajectory toward a rare asteroid.”

The use of a gravity-assist maneuver highlights the logistical constraints of deep-space exploration, where planetary alignment and physics are leveraged to save time and propellant. By targeting a metal-rich asteroid, NASA is attempting to sample a 'planetary core' that is otherwise inaccessible on Earth, potentially rewriting the timeline of how terrestrial planets consolidate their metallic centers.
