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.
