On 22 September 2017, after a two-day long sea operation, the first detection unit of the ORCA neutrino telescope came online. This marks an important milestone of the scientific and technological endeavour of the international KM3NeT Collaboration.
On 28 January 2016, scientists of the KM3NeT Collaboration have publicly announced KM3NeT 2.0, their ambition for the immediate future to further exploit the clear waters of the deep Mediterranean Sea for the detection of cosmic and atmospheric neutrinos. The published Letter of Intent details the science performance as well as the technical design of the KM3NeT 2.0 infrastructure.
