毅力号（Perseverance）再次捕捉到火卫一（Phobos）凌日

描述

Description

美国国家航天局（NASA）的毅力号火星车（Perseverance rover）利用其Mastcam-Z相机，捕捉到了火卫一（Phobos）——两颗火卫（Martian moon）之一——在2026年8月12日（任务第1,948个火星日，即sol）经过太阳前方的剪影。

NASA’s Perseverance Mars rover used its Mastcam-Z camera to capture the silhouette of Phobos, one of the two Martian moons, as it crossed in front of the Sun on Aug. 12, 2026, the 1,948th Martian day, or sol, of the mission.

这段动画经过了色彩处理，以模拟人类在火星表面佩戴防护性日食（solar eclipse）眼镜观看此次凌（transit）时的视觉效果。

The animation has been tinted to simulate what a human would see if they were watching the transit from the Martian surface through protective solar eclipse glasses.

自2021年2月在耶泽罗撞击坑（Jezero Crater）着陆以来，毅力号已经多次捕捉到火卫一凌日。通过对比各项记录，科学家们能够完善对这颗马铃薯状卫星轨道的理解，并了解其轨道如何发生变化。预计在漫长的岁月之后，火卫一的轨道最终会将这颗卫星引向火星（Mars）表面。

Perseverance has captured several Phobos transits since its landing at Jezero Crater in February 2021. By comparing the various recordings, scientists can refine their understanding of the potato-shaped moon'’ orbit, learning how it is changing. Eons from now, Phobos’ orbit is expected to eventually send the moon toward the Red Planet’s surface.

亚利桑那州立大学负责Mastcam-Z仪器的运行，并与圣迭戈的Malin Space Science Systems合作进行相机的设计、制造、测试和操作，同时与哥本哈根大学尼尔斯·玻尔研究所合作进行校准目标的设计、制造和测试。

Arizona State University leads the operations of the Mastcam-Z instrument, working in collaboration with Malin Space Science Systems in San Diego, on the design, fabrication, testing, and operation of the cameras, and in collaboration with the Niels Bohr Institute of the University of Copenhagen on the design, fabrication, and testing of the calibration targets.

美国国家航天局（NASA）的喷气推进实验室（Jet Propulsion Laboratory）由加州理工学院为该机构管理，负责建造并管理毅力号火星车的运行。

NASA’s Jet Propulsion Laboratory, which is managed for the agency by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
