NASA的Psyche航天器于2026年5月15日成功完成火星掠过，距离火星表面2,864英里（4,609公里）1。此次掠过利用火星的引力对航天器进行加速并调整轨道，为2029年夏季与金属富集小行星Psyche的相遇做准备1。
在掠过期间，航天器上的多套科学仪器进行了成功测试1。成像仪拍摄了火星及其卫星火卫一和火卫二的观测数据1，中子谱仪成功检测到来自火星的中子信号1，磁强计也在这次飞行中完成了测试1。
NASA's Psyche spacecraft executed a successful flyby of Mars on May 15, 2026, passing within 2,864 miles (4,609 kilometers) of the planet's surface 1. The maneuver leveraged Mars's gravity to accelerate the spacecraft and adjust its trajectory for the mission's primary objective: an encounter with the metal-rich asteroid Psyche scheduled for summer 2029 1.
During the close approach, the spacecraft's suite of scientific instruments performed successfully 1. The imaging system, magnetometer, and gamma-ray neutron spectrometer all collected data, with the neutron spectrometer detecting particles from Mars's atmosphere and the imaging system capturing views of the planet's two moons, Phobos and Deimos 1.
The Psyche mission launched in 2023 1. The successful Mars flyby marks a critical milestone in the spacecraft's journey toward the asteroid Psyche.
