阿尔忒弥斯二号：克里斯蒂娜·科赫的 PCD 故障
1 分•作者: robgibbons•4 个月前
在“阿尔忒弥斯2号”任务的早期，克里斯蒂娜·科赫的PCD（个人计算设备，本质上是一台Surface平板电脑）完全无法开机。休斯顿指挥中心让她尝试了几次硬重启（同时按住电源键和音量增大键），后来又让她取下SD卡再试一次，甚至一度将最后尝试让其运行的努力称为“绝望一搏”。
这些努力最终都失败了，这次设备故障导致机组人员在整个任务剩余期间不得不四个人共用三台可用的PCD。尽管并非一帆风顺，他们还是设法让这种配置运作起来。他们的PCD是直接用来跟踪工作、记录工作、运行检查清单、查找操作程序等的工具。特别是在月球飞掠期间，当他们拍摄各种月球目标时，他们说不得不轮流更换SD卡，因为他们轮流负责窗口观察。其中两人保留了自己的PCD，另外两人共用一台。休斯顿指挥中心最初要求他们尝试使用带有自己首字母的独立目录来跟踪工作，以防他们共用SD卡。
很明显，他们设法解决了问题，但这个问题也使他们的操作后勤变得复杂，而且有趣的是，这件事根本没有被报道。如果你搜索任何与“阿尔忒弥斯2号”任务相关的技术故障或设备故障，所有内容都集中在Outlook和厕所上。完全没有关于PCD完全故障的报道。没有任何相关报告，甚至连一篇博文都找不到。

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.
