阿耳忒弥斯2号宇航员飞越地月中点：目前距月球更近Artemis II Astronauts Pass Halfway Point to Moon, Sending Earth Photos

美国国家航空航天局（NASA）于2026年4月4日宣布，执行阿耳忒弥斯2号（Artemis II）任务的四名宇航员已成功飞越地球与月球之间的中点。目前，猎户座（Orion）飞船距离月球的距离已经短于其距离地球的距离，这标志着自1972年阿波罗17号任务结束以来，人类首次在深空航行中如此接近月球。休斯顿任务控制中心在周五晚间（协调世界时周六凌晨）与宇航员进行了通话，正式告知他们这一具有里程碑意义的时刻。此次任务不仅是对飞船性能的严苛测试，更是人类重返月球表面并最终前往火星的关键一步。 在飞向月球的过程中，宇航员们不仅要应对复杂的导航任务，还必须处理突发的设备故障。据NASA透露，宇航员在飞行途中成功修复了一个发生故障的厕所系统，确保了舱内生活的正常运行。与此同时，他们还利用先进的摄影设备捕捉到了地球在深空中逐渐缩小的壮观景象，并将其传回地面。这些照片展示了被旋转云层覆盖的蓝色海洋，引发了全球观众的广泛关注。尽管任务进展顺利，但宇航员们在与地面的交流中提到，由于长时间处于深空环境，他们已经开始对地球上的日期和时间感感到模糊。

NASA announced on April 4, 2026, that the four astronauts aboard the Artemis II mission have successfully passed the halfway point between Earth and the moon. The Orion spacecraft is now officially closer to the lunar surface than to Earth, marking the first time humans have ventured this far into deep space since the conclusion of the Apollo 17 mission in 1972. Mission Control in Houston held a scheduled call with the crew at approximately 11 p.m. Friday night (4 a.m. UTC Saturday) to inform them of this significant milestone. This mission serves as a critical test of the capsule's life-support and navigation systems, representing a foundational step in NASA's broader strategy to return humans to the lunar surface and eventually reach Mars. During their transit to the moon, the crew has balanced complex navigational duties with essential maintenance, including the successful repair of a malfunctioning onboard toilet. NASA reported that the astronauts managed to fix the waste management system while continuing their trajectory, ensuring the mission's operational integrity. Simultaneously, the crew captured and transmitted stunning high-resolution photographs of Earth as it receded into the distance. These images, showing the globe's vast oceans topped by swirling cloud formations, have captivated audiences worldwide. Despite the technical successes, the astronauts noted during communications with Earth that they have begun to lose track of the specific date and time back home due to the unique environment of deep-space travel.
