ISRO–ESA Extend Space Partnership to 2032, Expand Into Human Exploration

India and Europe have widened their long-standing partnership in space, with the Indian Space Research Organisation and the European Space Agency extending their cooperation framework until 8 January 2032 and bringing human spaceflight, robotic exploration and space weather into its formal scope.

ISRO Chairman Dr V. Narayanan and ESA Director General Josef Aschbacher formalised the extension through an exchange of letters in Paris on 10 September 2026, on the sidelines of the International Space Summit. ESA announced the expanded arrangement on 21 September.

The agreement builds on decades of cooperation between ISRO and ESA while adapting the relationship to India’s rapidly expanding ambitions in human spaceflight, space stations, lunar exploration and deep-space science.

ISRO–ESA Partnership Extended to 2032

The latest agreement extends the existing ISRO–ESA cooperation framework by another five years, taking it to January 2032.

More importantly, the two agencies have broadened the areas covered by the arrangement. Existing cooperation in Earth observation, satellite navigation, space science and mission operations will continue, while human space exploration, robotic exploration and space weather have now been explicitly incorporated.

The renewed framework also recognises the growing importance of the sustainable use of outer space as increasing numbers of government and commercial spacecraft enter Earth orbit.

For India, the expanded agreement comes as ISRO moves beyond its traditional strengths in launch vehicles, satellites and planetary missions towards sustained human activity in orbit and more ambitious exploration beyond Earth.

Human Spaceflight Becomes a Major Area of Cooperation

Human space exploration is one of the most significant additions to the relationship.

ISRO is preparing for the Gaganyaan programme, which is intended to establish India’s independent capability to send Indian astronauts into low-Earth orbit aboard an Indian launch vehicle and crew spacecraft.

ESA already has extensive experience supporting human missions through its participation in the International Space Station programme, astronaut training, life-support research, mission operations and development of human-rated spacecraft systems.

The expanded cooperation creates a framework through which the two agencies can examine areas where this European experience can complement India’s developing human-spaceflight infrastructure.

ESA Already Supporting Gaganyaan

Cooperation on Gaganyaan has already moved beyond discussions.

ISRO and ESA signed an agreement in December 2024 covering ground tracking support for India’s human-spaceflight missions. Under the arrangement, ESA’s ground-station network can provide tracking and communications support for Gaganyaan, helping maintain data and communication links with the orbital module during critical portions of its flight.

Reliable ground communication is particularly important for human missions because spacecraft telemetry, trajectory information, system health data and communications with astronauts must be maintained as continuously as possible.

International ground-station cooperation allows mission controllers to maintain contact as a spacecraft passes beyond the coverage of individual Indian tracking stations.

Cooperation Could Extend to Bharatiya Antariksh Station

The two agencies took another major step in May 2025, when they signed a Joint Statement of Intent covering cooperation in human space exploration.

That framework identified potential cooperation in astronaut training, analogue missions, parabolic-flight activities and scientific research. It also included discussions concerning rendezvous and docking interoperability, an important capability for future space-station operations.

Of particular long-term interest is India’s planned Bharatiya Antariksh Station, or BAS. ISRO intends to establish an Indian orbital station during the next decade, creating a permanent national platform for microgravity research, technology demonstrations and human spaceflight.

The ISRO–ESA framework has opened the possibility of future European astronaut participation in missions associated with India’s space station. Such flights have not yet been formally approved and would require separate mission-specific agreements, but their inclusion in bilateral discussions illustrates how far the relationship has progressed beyond conventional satellite cooperation.

Robotic Exploration Added to Partnership

Robotic exploration is another important addition to the renewed framework.

India has established substantial planetary exploration experience through missions including Chandrayaan and the Mars Orbiter Mission, while ESA operates a wide range of scientific spacecraft exploring the Moon, Mars, the Sun and other destinations.

Future cooperation could involve scientific instruments, mission data, ground support, technology development or complementary exploration activities.

The earlier ISRO–ESA human exploration framework also identified opportunities connected with lunar robotic science, creating a pathway for deeper scientific collaboration as both India and Europe expand their activities around the Moon.

No specific new joint lunar mission has been announced under the September 2026 agreement. Individual projects would require separate technical and financial arrangements between the agencies.

Space Weather Becomes a Formal Cooperation Area

Space weather has also been added to the partnership.

Solar flares, coronal mass ejections and other solar phenomena can disturb Earth’s magnetic environment and affect satellites, navigation signals, radio communications and electrical infrastructure.

India has strengthened its ability to study the Sun through Aditya-L1, positioned around the Sun–Earth L1 region to conduct continuous observations of the solar atmosphere and related phenomena.

ESA similarly operates extensive solar and space-weather research programmes. Closer cooperation can allow scientists to combine observations and improve understanding of conditions that can affect spacecraft and technological infrastructure around Earth.

Earth Observation and Navigation Cooperation Continues

The expanded agreement does not replace the more established areas of ISRO–ESA cooperation.

Earth observation remains a major component of the relationship. Both agencies operate extensive satellite programmes monitoring climate, oceans, land, vegetation, atmospheric conditions and natural hazards.

Satellite navigation is another continuing area of cooperation, particularly as India develops and expands NavIC while Europe operates the Galileo global navigation satellite system.

Scientific missions and mission operations will similarly remain within the bilateral framework, allowing the agencies to continue sharing expertise and infrastructure where mutually beneficial.

Sustainable Use of Space Gains Importance

The renewed framework also reflects increasing international concern over the long-term sustainability of space activities.

Earth orbit is becoming more congested as governments and commercial operators deploy larger numbers of satellites. At the same time, thousands of pieces of orbital debris create collision risks for operational spacecraft.

India is developing indigenous Space Situational Awareness capabilities through ISRO’s NETRA programme, while ESA operates extensive European programmes for space surveillance, debris monitoring and space safety.

Greater cooperation in this field could complement both agencies’ efforts to protect spacecraft and improve understanding of the orbital environment.

From Satellite Cooperation to Human Exploration

The significance of the 2026 agreement lies in how the ISRO–ESA relationship is changing.

Earlier cooperation was centred largely on scientific missions, satellite applications, Earth observation and operational support. The addition of human exploration, robotics and space weather moves the partnership into areas that will become increasingly important as India’s space programme enters its next phase.

Gaganyaan will establish the foundation for Indian human spaceflight. The Bharatiya Antariksh Station is intended to extend that capability towards sustained operations in low-Earth orbit, while India’s lunar programme is progressing towards increasingly complex robotic and eventually human exploration objectives.

Europe brings decades of experience in international human-spaceflight operations, sophisticated scientific spacecraft, astronaut training and deep-space exploration.

By extending their framework to 2032, ISRO and ESA have created a longer-term institutional structure through which those complementary capabilities can be developed into specific programmes.
