阿尔忒弥斯二号宇航员正按计划于周一绕月背面飞行，周六期间他们的猎户座乘员舱内整体情况平静，而地面工程师正努力解决一处马桶故障。
当地时间周五夜间，阿尔忒弥斯二号指挥官里德·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·汉森在此次历史性登月航程中达成了一项重要里程碑。
“‘阿尔忒弥斯号’，这里是休斯顿，我们有一些消息要告知你们，”任务控制中心的航天器通讯官杰基·马哈菲说道，“截至30秒前，你们距离月球已经比距离我们地球更近了。”

“哇哦，杰基，感谢告知我们这个消息，”科赫回应道，“我们所有人都不约而同地露出了喜悦的神情。很难想象这一刻，但我们可以从仪表上看到，我们距离月球还有11.8万海里。所以没错，大家可以算一算。”

她表示，机组人员正透过猎户座的对接舱窗口欣赏月球景观。
“这景色美不胜收，”科赫说道，“我们正越来越多地看到月球背面，能身处此地真的太激动了。”

自周三发射以来，机组人员的太空马桶就一直存在间歇性故障，他们偶尔会被要求改用可折叠应急尿袋（CCU）——一种用于收集尿液、之后可排入太空的袋子。
周六早些时候，机组人员准备就寝时，飞行控制人员无法按计划将马桶储存的尿液排放到太空中，可能是因为通风管结冰了。机组人员再次被指示使用应急尿袋，直到问题解决。
当日晚些时候，机组人员起床后，飞行控制人员调整了猎户座航天器的朝向，让阳光照射到废水通风管，希望融化任何结冰的物质。这一操作被称为“烘烤解冻”。
另一台太阳能翼摄像头对准了猎户座航天器，此前航天器已调整位置，让废水通风管喷嘴直接暴露在阳光下。目标是将其加热到足够温度，以融化疑似堵塞马桶尿液收集箱排放管路的冰体。 美国国家航空航天局（NASA）
“我们已经提高了喷嘴和管路本身的加热器温度，我们希望如果问题确实出在通风管结冰……那么这次操作将让我们有机会确认是否能够解决问题，”任务控制中心向机组人员无线电通报。
“我们会开启摄像头，届时将能拍下相关画面。受此影响，我们重新规划了夜间任务，你们的时间安排会略有变动。我们正推进部分任务，还有一些任务可能因为这次操作不得不从上午延后。”
资深宇航员唐·佩蒂特在X平台的社交媒体帖子中表示，应急尿袋“本质上是一个开放式容器（可重复使用、可密封、可排放），利用毛细力控制尿液与空气的界面，就像我的太空杯冲泡咖啡那样”，他指的是自己为微重力环境下喝咖啡设计的杯子。

“当你身处地月空间且马桶故障时，”他继续说道，“你需要备用方案，而应急尿袋可以替代大约25磅重的纸尿裤。”
除此之外，猎户座航天器表现良好。在分析显示航天器仍处于近乎完美的轨道后，原计划的轨道修正点火操作连续第二天被取消。
周六晚些时候，怀斯曼和格洛弗计划手动驾驶猎户座航天器，以帮助工程师更好地了解航天器在飞行中的表现，并为未来的阿尔忒弥斯宇航员提供实操反馈。
预计全体四名机组人员将在当日晚些时候花时间复盘周一绕月背面时拍摄月球表面的视频和相机测绘计划。预计于美国东部时间晚上7点03分在距月球约4100英里的高度抵达月球背面近地点。
月球已被低轨道卫星详细观测过，但阿尔忒弥斯二号机组将拥有独一无二的机会，直接观测人类从未亲眼见过的月球背面地貌。

Moon-bound Artemis II crew copes with toilet issue in otherwise smooth flight
April 4, 2026 / 3:56 PM EDT / CBS News
The Artemis II astronauts, on track for a flight around the dark side of the moon Monday, faced a relatively quiet day aboard their Orion crew capsule Saturday while engineers on the ground worked to solve a toilet issue.
Overnight, Artemis II commander Reid Wiseman, Victor Glover, Christina Koch and Canadian astronaut Jeremy Hansen reached a milestone of sorts on their historic voyage to the moon.
“And Integrity, (this is) Houston, we have some news to share with you,” called spacecraft communicator Jackie Mahafey in mission control. “As of 30 seconds ago, you are now closer to the moon than you are to us on Earth.”
A camera on the end of an Orion solar wing shows the spacecraft and its target — the moon — suspended in black of deep space. NASA
“Wow, Jackie, thank you for sharing that with us,” replied Koch. “We all kind of had a collective, I guess, expression of joy at that. It’s hard to imagine, but we can see here on our (instrumentation) that we are at 118,000 nautical miles (from the moon). So yeah, you can do the math.”
The astronauts looked back toward Earth Friday and captured this stunning shot of the home planet as a thin crescent. NASA
She said the crew was enjoying views of the moon through Orion’s docking hatch window.
“It is a beautiful sight,” Koch said. “We’re seeing more and more of the far side, and it’s just a thrill to be here.”

The crew has had intermittent problems with their space toilet since launch on Wednesday, occasionally being told to avoid its use in favor of collapsible contingency urinals, or CCUs, bags used for urine collection that can be emptied to space later.
Early Saturday, as the crew was preparing for bed, flight controllers were unable to dump the toilet’s stored urine overboard as needed, possibly because of a frozen vent line. The astronauts were told, once again, to use their CCUs until the problem was resolved.
Later in the day, after crew wakeup, flight controllers re-oriented the Orion capsule to allow sunlight to warm up the waste water vent line in hopes of thawing any frozen material. The procedure was referred to as a “bake out.”
Another solar wing camera was aimed at the Orion spacecraft after the ship was maneuvered to put a waste water vent nozzle in direct sunlight. The goal was to warm it up enough to thaw out suspected ice in a waste line preventing flight controllers from emptying a urine collection tank used by the capsule’s toilet. NASA
“We have increased the heater temperatures on the nozzle and the lines themselves, and we’re hoping that if the problem is the freezing of the vent lines … then this will give us a chance to see if we’re able to solve that,” mission control radioed the crew.
“We’ll have the cameras on it and we’ll be able to take pictures of that. Due to all of this, we’ve replanned overnight, your timeline is going to be a little bit in flux. We’re working on pulling some things forward. Some things might have to move off of the morning because of this maneuver.”
Veteran astronaut Don Pettit said in a social media post on X that a CCU is “essentially an open container (reusable, sealable and drainable) that controls the urine-air interface using capillary forces like my Space Cup does coffee,” he said, referring to a cup he designed for drinking coffee in weightlessness.

“When you are in cislunar space with a broken toilet,” he continued, “you need contingencies, and the CCU replaces the need for about 25 pounds of diapers.”
Otherwise, Orion was performing well. For the second day in a row, a planned trajectory correction thruster firing was called off after analysis showed the spacecraft was still on a near-perfect trajectory.
Later Saturday, Wiseman and Glover planned to take a turn at manually piloting the Orion capsule to help engineers better understand how the spacecraft performs in flight and to provide hands-on feedback for future Artemis astronauts.
All four crew members were expected to spend time late in the day reviewing their plans for video and camera mapping of the lunar surface when they pass behind the moon on Monday. Close approach on the far side, at an altitude of about 4,100 miles, is expected at 7:03 p.m. EDT.
The moon has been observed in great detail by satellites at lower altitudes, but the Artemis II crew will have a unique chance to observe features on the lunar far side that no human has ever directly experienced.
