NASA's Psyche Probe Nears Mars for Gravity Boost

NASA's Psyche probe is approaching Mars for a critical gravity assist that will set it on course toward its ultimate destination: a rare, metal-rich asteroid also named Psyche. According to multiple reports, the spacecraft is expected to pass within 2,800 miles of Mars at approximately 12,333 miles per hour on Friday.

The gravity boost from Mars will help conserve the probe's xenon gas propellant and adjust its trajectory toward the asteroid belt between Mars and Jupiter. The Psyche mission was launched in October 2023 and is scheduled to reach the metal-rich asteroid by August 2029, where it will spend 26 months studying the celestial object.

The asteroid Psyche is believed to be the remnant core of an ancient protoplanet. According to NASA, this mission aims to gain a better understanding of how Earth and other rocky planets formed around molten metal cores. The spacecraft's instruments will measure the asteroid's gravity, magnetic properties, and composition during its two-year study.

During the Mars flyby, Psyche's science instruments will be activated for practice and calibration. Special cameras designed to capture images in different wavelengths of light will photograph Mars as it appears crescent-shaped on approach and nearly full once it is behind the spacecraft. The data collected from this encounter will help fine-tune the probe's instruments before its arrival at the asteroid Psyche.
