November 18 – What a day! After a stand-by of 24 hours, due to uncertain weather conditions, the Castor and the Janus left the French coast headed to the KM3NeT/ORCA site. Ahead is one week of hard work to enlarge the deep-sea neutrino telescope.
Onboard the Castor are seven new detection units, carrying in total 126 optical modules, and one autonomous acoustic beacon. The Janus is instead equipped with a Remotely Operated Vehicle (ROV), which will be maneuvered from the ship to perform the deep-sea action: inspection of the submarine structures and connections of the new detection units to the already installed submarine network.
As we write this post, the two ships are at the site and the operation is being started.
