NASA的巨型月球火箭已暂停发射至少至4月，本周将返回机库进行更多维修，之后宇航员才能登上。
航天局周日表示，在天气允许的情况下，目标是周二开始这段穿越肯尼迪航天中心的四英里缓慢路程。
航天局在周日的声明中称：“为将火箭和航天器运回车辆装配大楼（VAB）而迅速开展准备工作，有可能保住4月的发射窗口，但这取决于数据结果、维修工作以及未来几天和几周的计划执行情况。”
美国国家航空航天局周四刚刚完成了一次重复燃料加注测试，以确保危险的液氢泄漏被堵住，此时又出现了另一个问题。
这一次，火箭的氦气系统发生故障，进一步推迟了半个多世纪以来宇航员首次登月之旅。
工程师们刚刚解决了氢泄漏问题，并确定了3月6日的发射日期（已经晚了一个月），此时氦气问题又出现了。流向火箭上级的氦气供应中断；氦气需要用于清洗发动机和给燃料箱加压。
“返回肯尼迪航天中心的车辆装配大楼是为了确定问题原因并予以修复，”NASA在一份声明中表示。
美国国家航空航天局表示，迅速的回滚准备工作保留了4月的发射尝试，但强调这将取决于维修工作的进展。该机构每个月只有几天时间可以将四名机组人员送往月球附近并返回。
阿尔忒弥斯二号任务旨在将四名宇航员——里德·怀斯曼（Reid Wiseman）、维克多·格洛弗（Victor Glover）、克里斯蒂娜·科赫（Christina Koch）和加拿大宇航员杰里米·汉森（Jeremy Hansen）——送往绕月球远端飞行并返回的任务，以全面测试该机构的猎户座深空舱，为2028年的阿尔忒弥斯三号月球着陆任务扫清道路。
NASA在一份声明中称，机组人员已于周六解除隔离，目前仍在休斯顿。他们将成为自美国国家航空航天局阿波罗计划（1968年至1972年间将24名宇航员送往月球）以来首批登月的人。
NASA to start slow-moving process returning moon rocket to hangar this week

Grounded until at least April,NASA’s giant moon rocketis headed back to the hangar this week for more repairsbefore astronauts climb aboard.
The space agency said Sunday it’s targeting Tuesday for the slow, four-mile trek across Kennedy Space Center, weather permitting.
“The quick work to begin preparations for rolling the rocket and spacecraft back to the VAB (Vehicle Assembly Building) potentially preserves the April launch window, pending the outcome of data findings, repair efforts, and how the schedule comes to fruition in the coming days and weeks,” the space agency said in a statement on Sunday.
NASA had barely finished arepeat fueling test Thursday, to ensure dangerous hydrogen fuel leaks were plugged, when another problem cropped up.
This time, the rocket’s helium system malfunctioned, further delaying astronauts’ first trip to the moon in more than half a century.
Engineers had just tamed the hydrogen leaks and settled on a March 6 launch date — already a month late — when the helium issue arose. The helium flow to the rocket’s upper stage was disrupted; helium is needed to purge the engines and pressurize the fuel tanks.
“Returning to the Vehicle Assembly Building at Kennedy is required to determine the cause of the issue and fix it,” NASA said in a statement.
NASA said the quick rollback preps preserve an April launch attempt, but stressed that will depend on how the repairs go. The space agency has only a handful of days any given month to launch the crew of four around the moon and back.
The Artemis II mission aims to sendfour astronauts— Reid Wiseman, Victor Glover, Christina Koch and Canadian astronaut Jeremy Hansen — on a flight around the far side of the moon and back to thoroughly test the agency’s Orion deep space capsule to help clear the way for a lunar landing mission, Artemis III, in 2028.
The crew members were released from quarantine on Saturday and remain in Houston, NASA said in a statement. They will become the first people to fly to the moon since NASA’s Apollo program that sent 24 astronauts there from 1968 through 1972.
