The European Space Agency and the Indian Space Research Organisation signed an exchange of letters extending their long-standing Cooperative Agreement for a further five years, to 8 January 2032, ESA said in a news item published on 21 September 2026. The signature took place in Paris on 10 September 2026, on the margins of the International Space Summit.

The agreement, in force since January 2002, provides the framework for cooperation across a broad range of space activities. The two agencies have previously worked together on Earth observation, satellite navigation, space science and mission operations support. The updated agreement adds space weather and human and robotic exploration to its existing areas of cooperation and recognises the growing importance of the sustainability of outer space activities.

ESA Director General Josef Aschbacher said international cooperation remains essential as space activities expand beyond Earth orbit, describing a partnership spanning more than two decades. ISRO Chairman V. Narayanan said the renewal reflects the two agencies' shared ambition to pursue innovation and scientific progress.
