美国航天局将Artemis II乘员月球飞行时间推迟到4月, NASA delays Artemis II crewed moon flyby to April due to helium leak in rocket’s upper stage, requiring repairs.

美国航天局的Artemis II飞行任务是50多年来首次乘员飞行的月球飞行,由于在空间发射系统火箭的末级中新发现的氦流问题,该飞行任务被推迟至4月。 NASA’s Artemis II mission, the first crewed lunar flyby in over 50 years, is delayed into April due to a newly discovered helium flow issue in the Space Launch System rocket’s upper stage. 这个问题与先前的氢泄漏无关,扰乱了发动机净化和燃料罐加压,需要修复肯尼迪航天中心车辆组装大楼。 The problem, unrelated to prior hydrogen leaks, disrupts engine purging and fuel tank pressurization, requiring repairs in the Vehicle Assembly Building at Kennedy Space Center. 这枚322英尺长的火箭很可能被推回原地工作,将发射推到3月窗口之外。 The 322-foot rocket is likely to be rolled back for work, pushing the launch beyond the March window. 四名宇航员仍在隔离区,美国航天局强调安全和彻底测试。 The four astronauts remain in quarantine, and NASA emphasized safety and thorough testing. 拖延是在一系列技术挫折之后发生的,包括2022年未孵化的阿耳特弥斯一号试验中出现的问题。 The delay follows a series of technical setbacks, including issues from the 2022 uncrewed Artemis I test.
