阿尔忒弥斯二号：克里斯蒂娜·科赫的PCD失败
在阿尔忒弥斯2号任务的早期，克里斯蒂娜·科赫的个人计算设备（PCD，实质上是一个Surface平板电脑）完全无法开机，休斯顿让她尝试多次进行硬重置（同时按住电源键和音量加键），后来又让她取出SD卡再试一次，甚至在某个时刻将最后的努力称为“绝望一击”。
这些努力最终未能成功，这一设备故障导致四名宇航员在整个任务剩余时间内只能共享三台正常工作的PCD进行所有工作。他们设法让这种配置运作，尽管并不容易。PCD是他们直接跟踪工作、记录工作、执行检查清单、查找程序等的工具。在特别的月球飞越期间，他们在拍摄各种月球目标时表示，必须在轮换窗口值班时更换SD卡。其中两人保留了自己的PCD，另外两人共享一台。休斯顿最初要求他们在共享SD卡时使用带有自己姓名首字母的独立目录来跟踪工作。
显然，他们能够让事情运作起来，但这个问题也使他们的操作后勤变得复杂，令人感到有趣的是，这一点竟然没有被报道。如果你查找与阿尔忒弥斯2号任务相关的技术故障或设备故障的信息，几乎都是关于Outlook和厕所的内容，完全没有提到PCD的彻底故障。我找不到任何关于此的报道，甚至连一篇博客文章都没有。

Early in the Artemis 2 Mission, Christina Koch's PCD (personal computing device, essentially a Surface tablet) completely failed to power on, and Houston had her attempt to perform a hard reset (hold down the power button, and the volume up button) several times, later having her remove the SD card and try again, at one point referring to last ditch efforts to get it running as a "hail-mary."<p>These efforts were ultimately unsuccessful, and this equipment failure led to the crew having to share three working PCDs between the four of them for all of their work for the entire remaining duration of the mission. They were able to make this configuration work, albeit not without complications. Their PCDs were their direct means of tracking their jobs, documenting their work, running checklists, looking up procedures, etc. During the lunar fly-by in particular, while they were doing photography of their various lunar targets, they said that they had to swap out SD cards as they rotated between window duty every so often. Two of them kept their own PCD, and the other two shared one. Houston originally asked that they try to use separate directories with their initials to track their work in case they were sharing SDs.<p>It's obvious that they were able to make things work, but this issue also complicated their operational logistics, and it's funny that it wasn't reported on at all. If you look up anything related to technical glitches or equipment failures on the Artemis II mission, it's all about Outlook and the toilet. Nothing about the complete failure of the PCD. No reports on this, not even a single blog post I can find.
