NASA's Psyche spacecraft has completed a close flyby of Mars, using the planet's gravity to adjust its trajectory toward the metal-rich asteroid Psyche. The mission captured thousands of images of the Martian surface, including detailed views of wind streaks, craters, and the south polar cap. The spacecraft is now continuing its journey and is scheduled to arrive at its asteroid target in August 2029.
Facts First
- Psyche performed a gravity-assist flyby of Mars on May 15, 2026, coming within 2,864 miles of the surface.
- The maneuver provided a significant speed boost of about 1,000 miles per hour and shifted the spacecraft's orbital plane.
- The spacecraft captured detailed images of Mars, including views of the Syrtis Major region, Huygens crater, and the south polar cap.
- Instruments were powered up for calibration during the approach, gathering data to prepare for the asteroid encounter.
- The mission is on course for the main asteroid belt, with arrival at asteroid Psyche scheduled for August 2029.
What Happened
On May 15, 2026, NASA's Psyche spacecraft successfully completed a close flyby of Mars. The spacecraft came within 2,864 miles (4,609 kilometers) of the planet's surface, utilizing a gravity assist to increase its speed and adjust its orbital plane. Don Han, Psyche's navigation lead at NASA's Jet Propulsion Laboratory (JPL), confirmed the maneuver provided a boost of about 1,000 miles per hour and shifted the spacecraft's orbital plane by approximately 1 degree relative to the Sun. During the approach, the spacecraft's instruments, including imagers, magnetometers, and a gamma-ray and neutron spectrometer, were powered up for calibration. The mission captured thousands of images of Mars, processed into both natural-color and enhanced-color views.
Why this Matters to You
This successful maneuver demonstrates the precision of interplanetary navigation, a technology that enables more efficient exploration of our solar system. The detailed images and data collected during the flyby contribute to our understanding of Mars, a planet that is a key target for future robotic and human exploration. The calibration of Psyche's instruments using a well-studied world like Mars increases the likelihood of high-quality scientific returns when the spacecraft reaches its primary target, the asteroid Psyche, which could provide unique insights into the building blocks of planets.
What's Next
The Psyche spacecraft will now resume its journey using its solar-electric propulsion system to travel to the main asteroid belt between Mars and Jupiter. Calibration imaging of Mars will continue for the remainder of the month as the spacecraft recedes. The mission is scheduled to arrive at the metal-rich asteroid Psyche in August 2029, where it will insert into orbit. Upon arrival, the spacecraft will map the asteroid through a series of circular orbits at varying altitudes to study this object, which is thought to be the partial core of a planetesimal.
