On 13–16 November, representatives of the National Centre for Nuclear Research (NCBJ) held a series of intensive and fruitful meetings with partners from China and Europe. The talks focused on the progress of work on the POLAR-2 instrument and further strengthening international cooperation in the field of space research and high-energy physics. It was a time full of inspiring discussions and plans that bring the project closer to implementation.

On 13 November, another working meeting of the POLAR-2 collaboration was held, attended by representatives of NCBJ, the Institute of High Energy Physics of the Chinese Academy of Sciences (IHEP) and the University of Geneva. The participants discussed the latest results of work on the instrument's subsystems, including laboratory tests and preparations for the integration of POLAR-2.
Dominik Rybka, MSc, project coordinator at NCBJ, presented the team's progress, highlighting the development of key electronic and structural components. The meeting agenda also included discussions on the planned launch of the instrument into Earth orbit in 2028 – an important milestone for the entire mission.

On 15 November, a meeting was held between representatives of the management of NCBJ, IHEP and European project partners: the University of Geneva and the University of Tübingen. The meeting was of a strategic nature and focused on strengthening cooperation and the exchange of experiences between the centres.
Prof. Jun Cao, Director of IHEP, presented the main directions of the institute's development, while Prof. Agnieszka Pollo, Deputy Director for Science at NCBJ, presented NCBJ's research priorities, including projects related to space instrumentation. The partners also discussed the current status of work on POLAR-2 and the prospects for expanding joint activities.

On 16 November, a delegation from NCBJ visited the Centre for Space Technology and Engineering (CSU) of the Chinese Academy of Sciences. During the visit, the infrastructure used to test instruments for the Chinese Space Station, including the Ground Analog System of CSS, was presented. The participants also learned about the functioning of the Payload Operation and Application Centre, responsible for operations and communication with the station.
The presentation part featured the profile of projects implemented at the CSU, and Prof. Agnieszka Pollo presented the key competences of the National Centre for Nuclear Research (NCBJ) in the field of radiation detection and high-energy physics. The talks focused on potential joint initiatives — from low-orbit missions to ambitious projects related to the exploration of the Moon.

The series of November meetings confirmed the dynamic development of cooperation between NCBJ, Chinese and European partners. The commitment of all parties strengthens the position of the POLAR-2 project on the international space research scene and paves the way for new, exciting joint ventures.
