阿尔忒弥斯二世任务是NASA半个世纪以来首次载人登月任务,其发射倒计时于周二顺利推进,工程师和技术人员正在为这枚巨型太空发射系统火箭以及猎户座乘员舱的加注燃料和周三晚间发射做准备。
在将非必要人员撤离“爆炸危险区域”并确认火箭与地面系统就绪后,工程师计划于美国东部时间周三早上7点34分左右开始,向这枚322英尺高的太空发射系统火箭的两个级段加注近76万加仑超冷液态氧和氢燃料。

燃料加注过程预计耗时约五个半小时,工程师们对此持乐观态度,认为2月份彩排倒计时期间出现泄漏的快速断开接头本次将不会再发生泄漏。
阿尔忒弥斯II号指挥官里德·怀斯曼、维克多·格洛弗、克里斯蒂娜·科赫以及加拿大宇航员杰里米·汉森当天进行了放松、复盘飞行计划以及听取倒计时进度更新等发射前一日的相关工作。
他们将于周三在燃料加注开始约两小时后被叫醒。用过早餐并参加天气简报会后,他们将穿上亮橙色抗压服,前往39B发射台,在6点24分进入为期两小时的发射窗口期间完成登舱就位。
气象预报员持续预测整个发射窗口内有80%的概率出现适宜发射的天气,但同时警告称,下午可能出现的云层堆积和局地阵雨可能会导致短暂延误,以便让云层或降雨离开发射区域。
NASA高级倒计时测试主任、曾参与航天飞机任务的杰夫·斯波丁表示,在发射控制中心工作的工程师和技术人员“对此感到兴奋并已准备就绪,这是我们自上世纪70年代以来重返月球征程的第一章”。
他说,进入倒计时最后一天时,工程师们没有遇到任何重大技术问题。

The countdown to launch of the Artemis II mission, NASA’s first piloted moonshot in half a century, proceeded smoothly Tuesday as engineers and technicians prepared the agency’s giant Space Launch System rocket and Orion crew capsule for fueling and blastoff Wednesday evening.
After clearing nonessential personnel from the “blast danger area” and verifying rocket and ground system readiness, engineers planned to begin pumping nearly 760,000 gallons of super-cold liquid oxygen and hydrogen fuel into the 322-foot-tall SLS rocket’s two stages starting around 7:34 a.m. ET Wednesday.

The fueling process will take about five and a half hours to complete, and engineers are optimistic a repaired quick-disconnect fitting that leaked during a dress rehearsal countdown in February will prove leak-free this time around.
Artemis II commander Reid Wiseman, Victor Glover, Christina Koch and Canadian astronaut Jeremy Hansen spent the day relaxing, reviewing their flight plans and getting updates on the countdown, among other day-before-launch tasks.
They will be awakened Wednesday about two hours after the start of fueling. After breakfast and a weather briefing, they’ll don their bright orange pressure suits and head for pad 39B to strap in for launch at 6:24 p.m., the opening of a two-hour window.
Forecasters continue to predict an 80% chance of favorable weather throughout the window, but warn that possible afternoon cloud buildups and isolated showers could prompt brief delays to allow time for clouds or rain to move out of the launch area.
Jeff Spaulding, NASA’s senior countdown test director and a space shuttle veteran, said engineers and technicians working in the launch control center “are excited and ready to go on this, this first chapter on our way back to the moon since the 1970s.”
He said engineers were not working any significant technical problems going into the final day of the countdown.
