The Indian Space Research Organisation (ISRO) and the European Space Agency (ESA) have renewed their longstanding partnership, extending their cooperation agreement for another five years through January 8, 2032. The updated framework also introduces new areas of collaboration, including human and robotic space exploration, space weather and the sustainable use of outer space.
The agreement was formalized through an exchange of letters signed in Paris on September 10, 2026, on the sidelines of the International Space Summit. ISRO Chairman Dr. V. Narayanan and ESA Director General Josef Aschbacher represented the two agencies during the renewal process.
The expanded partnership reflects the growing ambitions of India and Europe in space science, advanced technology and exploration beyond Earth orbit. It also provides a framework for both organizations to identify additional opportunities for joint research, mission development and technological advancement.
ESA said its cooperation agreement with ISRO originally came into force in January 2002. Over more than two decades, the agencies have collaborated across several fields, including Earth observation, satellite navigation, space science and mission operations support.
Josef Aschbacher emphasized that international partnerships are increasingly important as space activities expand and new possibilities emerge in exploration, sustainability and advanced technologies. He described the relationship between ESA and ISRO as a trusted partnership that could deliver further benefits to citizens and economies in both regions.
Dr. Narayanan similarly highlighted the practical value of cooperation between the two space agencies. He said the partnership has generated meaningful benefits for India and Europe while demonstrating how international collaboration can advance scientific and technological progress.
The revised agreement also recognizes the importance of protecting the long-term sustainability of activities in outer space. As more nations and organizations expand their presence in orbit, responsible space operations are becoming an increasingly important area for cooperation.
The renewed framework builds on earlier efforts to strengthen collaboration in human space exploration. In May 2025, ISRO and ESA signed a Joint Statement of Intent focused on human spaceflight, including potential cooperation involving low Earth orbit and future lunar exploration.
ESA officials had also expressed interest in exploring collaboration with India on human spaceflight, lunar missions and Venus exploration during discussions with the Indian delegation at the International Space Summit.
The latest agreement reinforces the commitment of both agencies to pursue scientific discovery, technological innovation and new exploration opportunities through sustained international cooperation.
