NASA’s Psyche spacecraft successfully flew by Mars on May 15, coming within 2,864 miles of the planet’s surface. This maneuver used Mars’ gravity to boost the spacecraft’s speed toward its destination, the metal-rich asteroid Psyche, located in the main asteroid belt between Mars and Jupiter. The flight team confirmed the spacecraft’s correct trajectory after analyzing radio signals.
During the flyby, all of Psyche’s instruments were activated and calibrated, providing valuable data for its upcoming mission. The spacecraft captured thousands of images of Mars, including a unique perspective where Mars resembled a thin crescent moon. These observations will aid in calibrating the imaging instruments for future asteroid studies.
Psyche’s magnetometer may have detected Martian bow shock, and spectrometer teams collected data for instrument calibration by comparing it to existing Mars data. Following the flyby, Psyche will resume its solar electric propulsion system to reach the asteroid, aiming for an arrival in August 2029. The mission could give insights into the interior of rocky planets like Earth if Psyche proves to be the metallic core of an ancient planetesimal.
The Psyche mission is led by Arizona State University, with various teams collaborating on different aspects of the mission.
