LOS ANGELES, June 6 — NASA’s Psyche spacecraft has used Mars as a gravitational slingshot to gain speed without burning extra fuel, a significant milestone in its journey to the metal-rich asteroid 16 Psyche in the main asteroid belt. The spacecraft flew about 4,609 kilometers above Mars on May 15, picking up roughly 1,600 kilometers per hour and slightly adjusting its orbit toward its destination, with arrival planned for 2029.
This maneuver not only saved fuel but also gave scientists a rare crescent view of Mars, with sunlight scattering through high-altitude dust, and served as a full rehearsal in which Psyche switched on its science instruments, tested cameras and collected calibration data. The flyby provided a glimpse of the planet’s atmosphere that is not often seen.
The spacecraft’s instruments were tested, ensuring that everything is working as expected for the main event.
Asteroid 16 Psyche is believed by scientists to be the exposed metallic core of an early failed planet, meaning that the mission could let scientists study something similar to the deep iron core of Earth, a place that no spacecraft can ever reach directly. The fact that the spacecraft was able to use Mars as a gravitational slingshot is a testament to the ingenuity and precision of the mission.
As the spacecraft continues on its journey to asteroid 16 Psyche, it will provide scientists with new information and insights into the formation and composition of this asteroid. With the Mars flyby now behind it, the Psyche spacecraft is one step closer to its destination, and scientists are eagerly awaiting the discoveries that it will make when it arrives at asteroid 16 Psyche in 2029. As we look to the future, it will be exciting to watch the progress of this mission and the new insights it will provide into the mysteries of our solar system.
