Discuss the significance of private participation in India's space sector post the Indian Space Policy, 2023, with reference to recent satellite missions.

The Indian Space Policy, 2023 formally opened the entire space value chain to Non-Governmental Entities (NGEs), confining ISRO to R&D, shifting operations to NSIL and making IN-SPACe the single-window authoriser [1]. Recent private missions show this shift is already delivering capability, though not without risk.

Enabling framework

• Policy demarcates roles of ISRO, IN-SPACe, NSIL and NGEs, giving private firms legal clarity to own and operate satellites [1].
• Liberalised FDI norms permit 74% automatic route in satellite manufacturing and operations, 49% in launch vehicles and spaceports, 100% in components [2].
• IN-SPACe's ₹1,000 crore Venture Capital Fund and Technology Adoption Fund address early-stage capital gaps [3].

Significance demonstrated by recent missions

• Technological: Bengaluru start-up GalaxEye's Mission Drishti — the world's first OptoSAR satellite fusing electro-optical and Synthetic Aperture Radar sensors on one platform — proved frontier innovation is possible outside ISRO [4].
• Indigenisation: at ~190 kg, India's largest privately built Earth observation satellite, developed by IIT Madras alumni engineers, deepening domestic design capacity [4].
• Economic: the space economy stands near $8.4 billion with close to 400 start-ups, projected to expand several-fold this decade [3].
• Strategic: private all-weather, night-capable imaging supplements sovereign EO assets for agriculture, disaster response and border surveillance.

Persisting concerns

• Launch dependence: Drishti flew on a SpaceX Falcon 9 from Vandenberg, reflecting limited private launch capacity at home [4].
• Resilience gaps: contact was lost after a geomagnetic solar storm damaged an onboard system, underlining the need for radiation-hardening standards and space-weather advisories [4].
• Regulatory bandwidth of IN-SPACe and absence of a comprehensive Space Activities Act leave liability questions open.

Private participation has moved from peripheral vendorship to mission ownership, making it central to India's ambition of a larger share of the global space economy. Enacting a space activities law, scaling indigenous launch options and institutionalising space-weather resilience will convert such experiments into dependable national capability.
