NASA has invited the Indian Space Research Organisation (ISRO) to participate in its Moon Base programme, adding a lunar dimension to the growing India-US space partnership. The invitation followed the ninth India-US Civil Space Joint Working Group meeting, hosted at ISRO headquarters in Bengaluru on August 5 and 6, 2026.
The talks covered civil and commercial space cooperation, science, human spaceflight and long-term exploration. India and the US also reviewed work under the Artemis Accords and the NISAR mission. An invitation does not mean India has formally accepted a Moon Base role. Further technical discussions will decide whether ISRO joins and what contribution it could make. That decision could shape India’s place in future lunar exploration.
Key Highlights
- NASA invited ISRO to join its Moon Base programme after the Bengaluru civil-space talks.
- The ninth joint working group meeting was held on August 5-6 at ISRO headquarters.
- Both sides discussed science, human spaceflight, commercial activity and Artemis Accords cooperation.
- NISAR and Axiom-4 have already created working-level experience between NASA and ISRO.
What Did NASA Offer ISRO At The Bengaluru Talks?
The Bengaluru meeting brought senior officials from both countries together as their space relationship moves beyond individual missions. ISRO Chairman V Narayanan and US Ambassador to India Sergio Gor addressed the opening session, with officials from ISRO, NASA and the US government joining the wider discussions.
The central development was NASA’s invitation for ISRO to join the Moon Base programme. NASA describes it as a long-term effort to establish an enduring human presence near the lunar South Pole, supported by transport, power, communications, mobility, habitation, robotics and science systems.
NASA’s Moon Base programme page says international collaboration will feature from early demonstrations through longer-term surface operations. The invitation therefore opens a route for talks about actual mission capabilities, although no Indian role has yet been announced.
Why Is The Moon Base Invitation A Bigger Step Than The Artemis Accords?
India joined the Artemis Accords in June 2023, becoming the 27th signatory at the time. The Accords set non-binding principles for peaceful and transparent exploration, including interoperability, emergency assistance, scientific data and the deconfliction of space activities.
The Moon Base invitation moves the conversation from shared principles towards possible operational participation. NASA is planning its base around the lunar South Pole and is seeking technologies for infrastructure, power, navigation, transport, mobility, habitation, autonomy and lunar science. Its June 2026 demonstration programme called for integrated systems that can progress towards flight or lunar-surface testing.
The project is already moving into missions. On June 30, NASA selected Astrobotic, Firefly Aerospace and Intuitive Machines for four Moon deliveries planned for late 2028, with awards totalling nearly $600 million.
For India, the timing is notable. Chandrayaan-3 demonstrated a soft landing in the Moon’s south polar region in 2023, while ISRO is expanding its human-spaceflight capability. A future Moon Base role could connect India’s lunar experience with technologies for astronauts, surface systems and longer-duration exploration.
How NISAR And Axiom-4 Built The Path To Deeper Cooperation
NASA and ISRO spent more than a decade developing NISAR, their first joint satellite mission. ISRO launched the 2,392 kg spacecraft aboard GSLV-F16 on July 30, 2025. It uses NASA’s L-band radar and ISRO’s S-band radar to observe changes in land, ice, water and vegetation. NASA says NISAR is now in its science phase.
Human spaceflight added another layer. ISRO astronaut Shubhanshu Shukla flew to the International Space Station as pilot of Axiom Mission 4 in June 2025. ISRO said the 18-day mission covered about 12 million kilometres and roughly 282 orbits, while Shukla completed seven Indian microgravity experiments. The experience was intended to support India’s human-spaceflight programme.
Commercial cooperation is growing too. A US-India Space Business Forum in Bengaluru in February 2026 brought together more than 200 government and industry participants, with 23 executives from 14 US space companies joining the trade mission. The bilateral agenda now extends from government missions to private launch, satellite, data and technology businesses.
What Happens Next For India-US Space Cooperation?
The immediate question is what participation NASA has offered and which areas interest ISRO. A Moon Base partnership could include science instruments, robotic systems, communications, navigation, mobility or surface technologies. Neither side has announced a specific package, funding arrangement or mission date.
The Bengaluru discussions also reaffirmed cooperation through the UN Committee on the Peaceful Uses of Outer Space and reviewed commercial-space opportunities. The next India-US space development may therefore come from the Moon, Earth observation, human spaceflight, space safety or private-sector partnerships.
For programme details, NASA’s official Moon Base material remains the clearest public guide to the capabilities being assembled and the openings for international collaboration.
