On October 10th, at the press conference on the achievements of the "Hailing Plan" of the South China Sea Neutrino Telescope at Shanghai Jiao Tong University, Li Zhengdao Research Institute officially released the blueprint for the "Hailing Plan". This project will explore the construction of China's first deep-sea neutrino telescope, which will explore the extreme universe by capturing high-energy (sub TeV to PeV level) celestial neutrinos.

It is reported that the Hailing team has completed its first sea trial mission, measuring and verifying the feasibility of a candidate sea area in the South China Sea as a neutrino telescope site, and completing the conceptual design of the "Hailing" neutrino telescope. The related paper was published in Nature Astronomy on October 9th.

The project's chief scientist and scholar Li Zhengdao, Xu Donglian, introduced that the "Hailing" telescope will use the entire Earth as a shield to receive neutrinos penetrating from across the Earth. "Due to its location near the equator, the" Hailing "telescope can detect neutrinos in 360 degrees across the sky through Earth rotation, achieving dead angle observation of neutrinos in different directions, complementing the Antarctic" Ice Cube "and other neutrino telescopes in the northern hemisphere

The first phase of the "Hailing" project has been launched at the end of 2022. It is planned to build a series of 10 telescopes in selected sea areas and connect them to an island base in the South China Sea through long-distance submarine cables. It is expected to build the world's first small neutrino telescope near the equator by 2026, and the "Hailing" telescope is expected to become the most advanced neutrino telescope in the world around 2030.
