NASA Invites ISRO to Join Moon Base Programme, Strengthening Indo-U.S. Space Ties

The National Aeronautics and Space Administration (NASA) has formally invited the Indian Space Research Organisation (ISRO) to join its Moon Base programme, a major step in deepening space cooperation between the United States and India. The invitation was extended during the ninth meeting of the India-U.S. Civil Space Joint Working Group (CSJWG), held recently at ISRO headquarters in Bengaluru.

According to a statement from the U.S. Embassy and Consulates in India, the invitation builds on the partnership between the two countries under the Artemis Accords. “NASA invited ISRO to join its Moon Base program, building on the two countries’ partnership under the Artemis Accords. The two sides also agreed to advance discussions for cooperation on open scientific data sharing under the Accords,” the statement said.

The Moon Base programme, as described by NASA, envisages the construction of humanity’s first outpost on another celestial body, located near the lunar South Pole. The ambitious project is planned to be executed in three phases and was announced during NASA’s “Ignition” event on March 24, 2026, where the agency unveiled a series of initiatives to advance American leadership in space.

The Bengaluru meeting, attended by ISRO Chairman V. Narayanan, U.S. Ambassador Sergio Gor, and senior officials from both countries, also advanced civil and commercial space cooperation under the U.S.-India Transforming the Relationship Utilizing Strategic Technology (TRUST) Initiative. This aligns with the February 2025 Joint Leaders’ Statement issued by Prime Minister Narendra Modi and President Donald Trump, which emphasized a shared vision for space exploration and technology collaboration.

During the discussions, both sides reviewed the successful launch of the joint NASA-ISRO Synthetic Aperture Radar (NISAR) mission last year and explored future cooperation in science and human spaceflight technology. They also reaffirmed their commitment to advancing the United Nations Committee on the Peaceful Uses of Outer Space (COPUOS) guidelines on the long-term sustainability of outer space activities and reviewed ongoing multilateral efforts to ensure the committee’s effectiveness.

ISRO’s inclusion in the Moon Base programme marks a significant milestone in India’s space journey. It reflects the growing trust and mutual interests between the two nations in exploring the lunar surface and beyond. The lunar South Pole, which is the target site for the outpost, is considered strategically important due to the presence of water ice and other resources that could support long-duration human missions.

For India, this collaboration could provide its scientists and engineers with exposure to cutting-edge space technologies and the opportunity to contribute to one of the most ambitious human spaceflight projects ever undertaken. It also strengthens the broader Indo-U.S. strategic partnership, which has expanded into multiple domains, including defence, trade, and technology.

The timing of the invitation is notable, as India has been making strides in its own space programmes, including the Chandrayaan and Gaganyaan missions. Joining the Moon Base programme could accelerate India’s capabilities in crewed spaceflight and deep-space exploration. However, details about the specific role ISRO will play in the programme, the timeline for its involvement, and the funding mechanisms have not yet been publicly disclosed.

The India-U.S. Civil Space Joint Working Group has served as a key platform for dialogue and cooperation between the two space agencies since its inception. The ninth meeting underscored the breadth and depth of the partnership, which now spans earth observation, satellite navigation, space science, and human spaceflight. The agreement to advance open scientific data sharing under the Artemis Accords is expected to further enhance transparency and collaboration in space research.

As the Moon Base programme progresses, the international community will be watching closely to see how India and the United States translate this invitation into tangible cooperation. The project not only holds scientific promise but also has significant geopolitical implications, as countries around the world compete and collaborate for influence in space. For now, the invitation stands as a testament to the enduring alliance between the world’s two largest democracies.
