NASA’s Psyche spacecraft recently made a close approach to Mars, capturing stunning images while using the planet’s gravity to increase its speed toward a distant asteroid. This maneuver, which took place on May 15, involved the spacecraft flying about 2,900 miles from Mars’ surface. By employing a gravity assist, Psyche’s speed increased by approximately 1,000 mph, allowing it to adjust its trajectory towards the asteroid 16 Psyche.
During this flyby, mission controllers seized the opportunity to photograph Mars from interesting angles. The images showcase details of the planet’s polar ice caps, intricate surface features shaped by wind, and various crater formations. NASA scientists noted that this close encounter helped them test and calibrate their scientific instruments in preparation for the asteroid mission.
Psyche was launched in October 2023 and is on a journey of 2.2 billion miles to reach its namesake asteroid, located in the outer asteroid belt. Scientists believe this asteroid may represent an exposed metallic core of a former planetary body. Understanding its composition could provide insight into the formation of rocky planets like Earth and their iron cores.
The spacecraft is set to arrive at 16 Psyche in summer 2029. Once there, it will spend several years mapping the asteroid’s structure and composition. If it is confirmed to be a fragment of a planetary core, this mission could open a unique view into the deep interiors of terrestrial worlds.
