NASA's Psyche spacecraft flew close to Mars and used its gravity to gain speed. This helped the spacecraft change direction and head towards a mysterious metal asteroid called Psyche.

Mars gave NASA's Psyche spacecraft a boost of 1,000 miles per hour and changed its path by about 1 degree relative to the Sun. The spacecraft is now on course to reach the asteroid Psyche in summer 2029.

The flyby also allowed scientists to test Psyche's scientific instruments before it reaches the asteroid. During the days leading up to the flyby, engineers powered up the spacecraft's cameras, magnetometers, and gamma-ray and neutron spectrometer.

As Psyche approached Mars, the planet appeared as a narrow crescent because of the angle between the spacecraft, Mars, and the Sun. Images taken by the spacecraft's camera showed the crescent stretching farther around the planet than expected. Scientists say sunlight scattering through Mars' dusty atmosphere likely caused the effect.

The spacecraft rapidly photographed the Martian surface as it crossed from the night side of the planet into daylight. This dataset provides unique opportunities for scientists to calibrate and characterize the performance of the cameras, as well as test the early versions of their image processing tools being developed for use at the asteroid Psyche.

Why It Matters

Understanding how spacecraft navigate through space is crucial for future missions to explore our solar system. This technology can also be applied to improve communication systems on Earth.
