NASA执行Artemis II任务载人飞船飞行距离达406771公里创人类最远纪录
摘要:
NASA于2026年4月完成Artemis II载人绕月飞行任务,四名宇航员搭乘猎户座飞船(Orion)飞行至距地球406771公里处,刷新人类航天最远距离纪录。
该任务采用自由返回轨道设计,利用月球引力实现飞船返航,飞行高度超过此前阿波罗13号任务保持56年的纪录。飞船距月球表面最远点约6400公里,未实施月面着陆。
此次任务验证了猎户座飞船与太空发射系统(SLS)的载人深空飞行能力,为后续Artemis III月面着陆任务奠定基础,标志美国重启载人登月计划进入实施阶段。

Title: NASA Artemis II Crew Sets 252,756-Mile Human Distance Record Free-Return Trajectory
Summary:
NASA’s Artemis II mission, carrying a four-person crew, has set a new record for the farthest distance traveled by humans from Earth at 252,756 miles (406,771 km), surpassing the 56-year-old record of 248,655 miles set by Apollo 13 in 1970. The crew, all aged 40s to 50s, flew approximately 4,000 miles beyond the Moon’s far side, exceeding the altitude of previous Apollo lunar missions.
The record was achieved using a free-return trajectory, leveraging the Moon’s gravity to slingshot the Orion spacecraft back toward Earth without requiring major propulsion maneuvers. This flight profile prioritizes crew safety and enables uncrewed systems testing ahead of future lunar landings. Artemis II did not land on the Moon but validated critical systems for deep space travel.
With only five Apollo-era astronauts still alive, Artemis II marks a generational shift in lunar exploration. The mission reinvigorates sustained human presence beyond low Earth orbit and sets the stage for Artemis III, which aims to return astronauts to the lunar surface. NASA and space advocates anticipate the new distance record will be surpassed sooner than its predecessor.
Key Takeaways:
Artemis II crew reaches 252,756 miles from Earth, breaking 56-year human distance record
Free-return trajectory enables safe lunar flyby without landing, tests Orion spacecraft systems
Mission advances NASA’s goal of sustained lunar exploration and future surface landings
