The NASA crew of the Artemis II spacecraft, currently on its way to the moon, is experiencing technical issues with Microsoft Outlook. A BlueSky user watching a live broadcast of NASA’s communications between mission control and the Artemis spotted this issue. The ground-based operator suggested remote access to the Portable Computing Device (Phew), which may be caused by the issue being identified as Optimus software. The astronauts have been using Outlook since at least 1991, although reportedly they weren't using Outlook at the time.
