Tech 24 - "Sanctuary on the moon" wants to send a message to extra-terrestrials (and to our descendants) “Draw inspiration from past projects with present tools, while preparing the archeology of the future.” This is how engineer Benoit Faiveley describes his “San sanctuary on the Moon” project, consisting of engraving a large part of current human knowledge on 24 sapphire discs. They will fly to the moon in 2027 aboard NASA's Artemis mission.
