Science & Technology · 14 August 2026 · Based on The Hindu (original report)

2-minute summary

During the ninth meeting of the India-U.S. Civil Space Joint Working Group (CSJWG) held in Bengaluru, the National Aeronautics and Space Administration (NASA) officially invited the Indian Space Research Organisation (ISRO) to collaborate on its ambitious Moon Base programme. The programme aims to establish humanity's first permanent outpost on a celestial body near the lunar South Pole across three planned phases. This partnership builds upon India's signing of the Artemis Accords and discussions around open scientific data sharing. The meeting also reviewed ongoing bilateral cooperation following the launch of the joint NASA-ISRO Synthetic Aperture Radar (NISAR) mission, future human spaceflight collaborations, and civil-commercial space initiatives under the TRUST (Transforming the Relationship Utilizing Strategic Technology) Initiative. Both nations reaffirmed their commitment to the United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS) guidelines on the long-term sustainability of outer space activities.

Why it's in the news

NASA has formally invited ISRO to join its Lunar Moon Base programme near the lunar South Pole. The invitation was extended during the 9th India-U.S. Civil Space Joint Working Group meeting in Bengaluru.

Background and context

India and the United States have steadily expanded their space partnership over recent decades, transitioning from basic scientific exchanges to complex joint ventures. Key milestones include the joint NASA-ISRO Synthetic Aperture Radar (NISAR) mission and India's accession to the Artemis Accords in 2023, a non-binding multilateral framework governing peaceful civil space exploration. With India's historic Chandrayaan-3 mission achieving the first soft landing near the lunar South Pole, ISRO demonstrated unique technological capability in lunar exploration. NASA's Moon Base programme, tied to its broader Artemis ecosystem, seeks to establish a sustained human and robotic presence on the Moon to serve as a stepping stone for future planetary exploration.

International organisations

• United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS) — Global body responsible for governing the exploration and use of space for the benefit of all humanity; both nations reaffirmed compliance with its Guidelines for the Long-term Sustainability of Outer Space Activities.
• National Aeronautics and Space Administration (NASA) — U.S. space agency leading the Moon Base programme and collaborating with ISRO on joint missions like NISAR and lunar exploration.

Previous UPSC questions on this theme

• Mains GS-3 2023 — What is the main task of India's third moon mission which could not be achieved in its earlier mission? List the countries that have achieved this task. Introduce the subsystems in the spacecraft launched and explain the role of the 'Virtual Launch Control Centre' at the Vikram Sarabhai Space Centre which contributed to the successful launch from Sriharikota.

Mains practice: Critically examine how growing India-U.S. space collaboration enhances India's strategic, scientific, and commercial interests in the emerging lunar economy.

The formal invitation by NASA for ISRO to join the Lunar Moon Base programme marks a major leap in India-U.S. space cooperation, reflecting India's growing stature in space exploration following the success of Chandrayaan-3.

• **Scientific & Technological Advancement**: Deep collaboration enables ISRO to share advanced R&D in life-support systems, lunar resource extraction (in-situ resource utilization), and deep-space habitats. Open scientific data sharing under the Artemis Accords will enrich India's planetary science research.

• **Strategic Alignment & Space Governance**: Engaging directly in base-building near the lunar South Pole consolidates India's position as a premier space power. It ensures India has an active voice in shaping norms, outer space safety standards, and space resource management under UN COPUOS guidelines.

• **Commercial and Industrial Synergies**: Bilateral mechanisms like the TRUST (Transforming the Relationship Utilizing Strategic Technology) Initiative create lucrative avenues for India's emerging private space sector (NewSpace India, IN-SPACe) to integrate into global supply chains for space hardware, robotics, and communications.

• **Cost Sharing and Risk Mitigation**: Complex deep-space missions require enormous capital outlays. Co-developing lunar infrastructure distributes high operational costs and technical risks across partner agencies.

**Conclusion**: Joining international lunar habitat initiatives provides India with a dual advantage—cementing its geopolitical partnership with the U.S. while accelerating its own domestic capabilities for long-duration human spaceflight and deep-space exploration.

Prelims practice questions

Q1. Consider the following statements regarding the Artemis Accords: 1. They are a set of non-binding principles grounded in the Outer Space Treaty of 1967. 2. India is a signatory to the Artemis Accords. 3. The Accords are legally binding treaties managed directly by the UN Security Council. Which of the statements given above is/are correct?

1. 1 and 2 only
2. 2 and 3 only
3. 1 only
4. 1, 2 and 3

Answer: A. Statements 1 and 2 are correct. The Artemis Accords are non-binding bilateral/multilateral principles grounded in the 1967 Outer Space Treaty. India joined the Accords in 2023. Statement 3 is incorrect because they are not managed by the UN Security Council, nor are they legally binding treaties.

Q2. The NISAR (NASA-ISRO Synthetic Aperture Radar) satellite mission is primarily designed to:

1. Track deep space solar storms and coronal mass ejections
2. Establish a human base on the Moon's South Pole
3. Observe and measure changes in Earth's ecosystems, ice-mass surfaces, and natural hazard processes
4. Search for deep underground water aquifers on Mars

Answer: C. NISAR is a joint Earth-observing mission by NASA and ISRO utilizing dual-frequency Synthetic Aperture Radar (L-band and S-band) to track changes in Earth's ecosystems, surface deformation, ice sheets, and natural hazards.

Q3. Which United Nations body is dedicated to reviewing international cooperation in outer space and developing guidelines for the long-term sustainability of space activities?

1. International Telecommunication Union (ITU)
2. UN Committee on the Peaceful Uses of Outer Space (UN COPUOS)
3. UN Conference on Disarmament (UNCD)
4. UN Office for Disaster Risk Reduction (UNDRR)

Answer: B. The United Nations Committee on the Peaceful Uses of Outer Space (UN COPUOS) was set up by the UN General Assembly to govern the exploration and use of space for peace, security, and development.
