美国航天局将Artemis II号乘员月球飞行时间推迟至至少4月,因为氦系统问题。
NASA delays Artemis II crewed moon flyby to at least April due to helium system issues.
美国航天局正在将其月球火箭滚回肯尼迪航天中心车辆组装大楼进行进一步的修理,将Artemis II号飞行任务推迟至至少4月。
NASA is rolling its moon rocket back to the Vehicle Assembly Building at Kennedy Space Center for additional repairs, delaying the Artemis II mission until at least April.
后退后继而来的是氦系统故障,中断了燃料加压和发动机净化,使最近对氢燃料泄漏的修补复杂化。
The rollback follows a helium system malfunction that disrupted fuel pressurization and engine purging, complicating recent fixes to hydrogen fuel leaks.
工程师正在调查这一问题,4月发射窗口仍有可能,但取决于修理进度。
Engineers are investigating the issue, with the April launch window still possible but dependent on repair progress.
这次飞行任务将派遣四名宇航员——三名美国人和一名加拿大人——乘乘乘月球的乘员,这是自1972年以来的第一次此类旅行。
The mission, which will send four astronauts—three Americans and one Canadian—on a crewed flyby of the moon, marks the first such trip since 1972.
机组人员仍然在休斯顿待命,由于轨道力学,每个月的发射机会有限。
The crew remains on standby in Houston, and launch opportunities are limited each month due to orbital mechanics.
