In memory of Professor Roger-Maurice Bonnet
The National Space Science Center of Chinese Academy of Sciences is deeply saddened by the passing of our long-time collaborator Professor Roger-Maurice Bonnet on 19 January 2026.
Professor Bonnet was a pioneering figure who laid the foundation for substantive cooperation in space science between China and the European Space Agency. In the 1990s and 2000s, he initiated the landmark collaboration between ESA's Cluster mission and China's Double Star Program, enabling the historic first six-point observations of geospace. As a key decision-maker, he made possible the first China-ESA cooperation at the mission level, paving the way for all future joint endeavors. This transformative partnership was later honored in 2010 with the IAA Laurels for Team Achievement Award.
Professor Bonnet was also instrumental in establishing the International Space Science Institute–Beijing (ISSI-BJ). As Executive Director of ISSI, he recognized the rapid growth of space science in China and valued the importance of Chinese contributions to global research, championing the creation of ISSI-BJ. His foresight has left an enduring legacy.
Furthermore, Professor Bonnet led the international review of the scientific missions under China’s Strategic Priority Program on Space Science, emphasizing scientific excellence, impact, and broad involvement. This guidance helped shape flagship missions in Strategic Priority Program on Space Science, which are equipped with world-class instruments addressing frontier scientific questions.
In recognition of his transformative role, Professor Bonnet was awarded the International Science and Technology Cooperation Award of the Chinese Academy of Sciences in 2009, as well as the China International Science and Technology Cooperation Award and the Friendship Award of Chinese Government in 2010—the nation’s highest honor for foreign experts—a fitting and profound official recognition of his contributions.
The National Space Science Center of CAS and the Chinese space science community at large will remember Professor Bonnet’s scientific spirit and his pioneering role in expanding China-Europe cooperation in space science.
