@beccadax @Trilobyter do you have any info about this that you can share?

@Lizette603_23 @beccadax not much, I didn’t have anything to do with the portable computing devices, they’re important for crew planning, schedules, email, etc, but they’re not critical for Orion vehicle function or safety. They connect to WiFi & network connections which have to tie in to the Orion uplink/downlink radio comms. From what I’ve heard that is part of what’s causing their PCD issues, it’s not the same as the earth-based internet the off-the-shelf devices & software are made for.

@Lizette603_23 @beccadax that said I’m curious why they didn’t uncover these issues before flight, but it may be the case that they tested the PCDs with the internal Orion network but not with the full path of the Deep Space Network radio comms - because you can only use the DSN when you are beyond low earth orbit (DSN uses the huge radio dish antenna ground stations) - or a good enough ground emulation of the DSN. There’s often unanticipated subtleties that get you no matter how much you test.
