Very legit Apple Vision Pro use case. NASA astronauts train underwater in a 6-million gallon pool with full-scale International Space Station (ISS) modules  and lunar surface mock-ups. Film it with Apple's Immersive Video camera, capturing 180-degree (ultra high-res 3D) footage.   Later on, astronauts and support crew can "re-enter" the training sessions with Apple Vision Pro headsets to improve techniques while prepping for future missions.
