关键测试遇燃料泄漏,美载人绕月任务再推迟一个月
Huan Qiu Wang Zi Xun· 2026-02-04 23:04
Core Viewpoint - The "Artemis 2" manned lunar mission by NASA has been delayed again due to a hydrogen leak detected during a wet dress rehearsal of the Space Launch System (SLS) rocket, pushing the launch date from February 8 to March [1][3]. Group 1: Mission Details - The "Artemis 2" mission is crucial as it aims to send astronauts to the Moon using the SLS rocket and the Orion spacecraft [5]. - The mission is expected to set a new record for the farthest distance from Earth achieved by humans, while also laying the groundwork for the subsequent "Artemis 3" mission [5]. Group 2: Technical Issues - During the wet dress rehearsal, over 700,000 gallons of cryogenic fuel were injected into the SLS rocket, but a hydrogen leak was detected, leading to the suspension of fueling operations [3][4]. - The leak was identified in the cavity between the umbilical plate and the rocket, causing the fueling process to be interrupted multiple times [4]. - The repair of the hydrogen leak is complex, requiring testing under the same conditions as the launch day, which can only be conducted at the launch pad [4]. Group 3: Future Plans - NASA plans to conduct another wet dress rehearsal to address the hydrogen leak and complete the remaining objectives that were not achieved in the first rehearsal [5]. - Potential new launch windows are set for March 6, 7, 8, 9, and 11, contingent on the resolution of the current issues [5].
