TL;DR
NASA’s Psyche spacecraft performed a planned flyby of Mars on May 15, using the planet’s gravity to increase speed and refine its course toward asteroid 16 Psyche. The maneuver is part of a six-year mission to study a metal-rich asteroid believed to be part of a planetary core.
NASA’s Psyche spacecraft successfully completed a planned flyby of Mars on May 15, using the planet’s gravity to increase its velocity and adjust its trajectory toward asteroid 16 Psyche. This maneuver is a critical step in its six-year journey to explore a metallic asteroid that could provide insights into planetary core formation.
During the flyby, Psyche passed within approximately 2,800 miles of Mars at a speed of about 12,300 mph, gaining a significant velocity boost from the planet’s gravitational pull. The spacecraft’s closest approach occurred around 3:30 PM Eastern Time, and it flew closer than Mars’s moons Phobos and Deimos, which orbit at distances of 3,700 miles and 12,470 miles respectively. The maneuver was pre-planned to optimize fuel efficiency, leveraging the spacecraft’s solar-electric ion thrusters that use xenon gas.
NASA’s team reports that Psyche’s cameras captured images of the planet during the flyby, which will be transmitted back via NASA’s Deep Space Network over the coming days and weeks. These images are expected to offer valuable visual data of Mars at a unique vantage point, as well as help refine the spacecraft’s trajectory for its upcoming mission phases.
Launched in late 2023, Psyche is now approximately 14,450 miles from Mars and traveling at a speed of about 10,710 mph after the gravity assist. The spacecraft is headed toward asteroid 16 Psyche, which it is expected to reach by July 2029. Once there, it will spend two years orbiting the asteroid to study its surface, map its features, and analyze its composition, which scientists believe could be part of an ancient planetary core.
Why It Matters
This gravity assist is a pivotal moment in Psyche’s mission, enabling it to conserve fuel and reach its target more efficiently. Studying 16 Psyche could unlock clues about the early formation of planets and the Earth’s core, offering a rare glimpse into planetary evolution and the violent history of the solar system. The mission’s findings may influence our understanding of planetary geology and the processes that shaped terrestrial planets.

Background
NASA’s Psyche mission was announced in 2017 and launched in late 2023, with a planned arrival at the asteroid in July 2029. The mission aims to explore the metallic asteroid, which is the largest known of its kind, believed to be a remnant of a planetary core formed during the early solar system. The use of gravity assists from planets like Mars is a standard technique to extend mission lifespans and improve trajectory precision in deep space exploration. Previous missions have used similar maneuvers to reach distant targets efficiently.
“The Mars flyby was a planned maneuver that will help Psyche reach its destination more efficiently and with greater precision. We are excited to see the first images from this encounter.”

What Remains Unclear
While the flyby was successfully executed, it is still unclear how the trajectory adjustments will precisely influence Psyche’s approach and data collection capabilities. The quality of the images captured during the flyby and their scientific value remain to be confirmed once received. Additionally, the overall impact of the maneuver on mission timelines and operations will become clearer as subsequent phases progress.

What’s Next
NASA will analyze the images taken during the Mars flyby and continue to track Psyche’s trajectory. The spacecraft will now focus on its cruise phase, with trajectory corrections if needed, leading up to its arrival at asteroid 16 Psyche in July 2029. Preparations for surface mapping, surface composition analysis, and detailed imaging will follow upon arrival.
