NASA’s Psyche Spacecraft to Perform Critical Gravity Assist Near Mars En Route to Metallic Asteroid

• May 9, 2026

NASA’s Psyche spacecraft is approaching a significant milestone in its interplanetary voyage to a unique metallic asteroid located within the main asteroid belt. Scheduled for May 15, 2026, the mission will undertake a close flyby of Mars, passing approximately 4,500 kilometers above the Red Planet’s surface.

Utilizing Mars for a Gravity Boost

This maneuver will serve as a gravity assist, a technique that leverages the gravitational force of a planetary body to accelerate a spacecraft without consuming additional fuel. The upcoming encounter with Mars represents the mission’s sole gravity assist event and is critical for setting Psyche on an optimal trajectory toward its primary target.

The primary goal of the Psyche mission is to explore a metal-rich asteroid, which is believed to contain valuable resources worth quintillions of dollars. By using Mars’ gravity, the spacecraft will gain necessary speed to cover the remaining distance more efficiently and reach the asteroid within its designated timeline.

Gravity assists are a common practice for missions traveling through the solar system, enabling significant savings in propulsion requirements and mission costs. For Psyche, this approach is essential given the vast distances involved and the spacecraft’s need to maintain an efficient path.

The asteroid targeted by Psyche stands out due to its unusual composition, believed to be primarily metallic, offering unique scientific insights into planetary cores and the early solar system’s formation. The data collected by the spacecraft upon arrival is expected to deepen understanding of planetary building blocks and resource potential in space.

While specific details regarding the spacecraft’s velocity increase during the flyby and subsequent mission timeline have not been disclosed, this gravity assist is widely recognized as a critical juncture in navigating Psyche closer to its long-term objectives.

As the spacecraft passes near Mars, mission controllers will monitor its trajectory and system health closely to ensure the gravity assist proceeds as planned. The success of this maneuver is essential for maintaining the mission’s schedule and maximizing the scientific return from the asteroid encounter.

The Psyche mission continues NASA’s efforts in planetary science and resource identification, aiming to extend knowledge beyond traditional rocky and icy celestial bodies. The upcoming Mars flyby marks a pivotal phase in the spacecraft’s journey toward unlocking new dimensions of space exploration.

NASA’s Psyche mission will fly within 4,500 km of Mars for a crucial gravity assist on its journey to a valuable metal-rich asteroid.
