美国航天局将阿耳特弥斯II号火箭送回去修理,将乘员月球任务推迟至至少4月。
NASA rolls back Artemis II rocket for repairs, delaying crewed moon mission to at least April.
美国航天局已将Artemis II号月球火箭从Pad 39B号发射场移至车辆组装大楼,以便在氦加压系统故障后进行修理,将乘员月球飞行任务推迟至至少4月。
NASA has moved the Artemis II moon rocket from Launch Pad 39B to the Vehicle Assembly Building for repairs following a helium pressurization system failure, delaying the crewed lunar fly-around mission until at least April.
这枚322英尺长的火箭在发射台上已停留一个月,在加注燃料测试后上级加压出现问题,不得不通过一辆历史悠久的履带运输器慢速返回4英里。
The 322-foot rocket, which had been on the pad for a month, had problems repressurizing its upper stage following a fueling test, necessitating a slow 4-mile return via a historic crawler-transporter.
工程师将检查和修理这一系统,其中包括在火箭自毁装置中更换电池。
Engineers will inspect and repair the system, which includes replacing batteries in the rocket's self-destruct mechanism.
这是在此前由于氢气泄漏导致的延迟之后发生的,将航天员Reid Wiseman、Victor Glover、Christina Koch和Jeremy Hansen的发射推到其原定目标之外。
This comes after previous delays due to hydrogen leaks, pushing the launch of astronauts Reid Wiseman, Victor Glover, Christina Koch, and Jeremy Hansen beyond their original targets.
推回使在受控制的环境中进行修理成为可能,发射窗口受轨道力学限制。
The rollback allows for repairs in a controlled environment, with launch windows limited by orbital mechanics.
