Key Challenges in India’s Space Sector

Limited Budget Allocation

• Despite ISRO’s achievements, India’s space sector operates on a relatively small budget compared to global counterparts, limiting deep-space missions and technological advancements.
• The majority of funding still comes from the government, restricting private sector innovation and commercialization.
• ISRO’s 2024-25 budget is Rs 13,042.75 crore ($1.95 billion), whereas NASA operates with a significantly larger budget of $25 billion.
• India’s space economy accounts for only 2% of the global space market, highlighting the need for increased investment.

Slow Development of Reusable and Cost-Effective Launch Technologies

• While ISRO has made progress with Reusable Launch Vehicle (RLV) experiments, it lags behind private players like SpaceX (Falcon 9) and Blue Origin (New Shepard) in operational reusable rockets.
• High launch costs limit India’s ability to compete in the global commercial satellite launch market, which demands low-cost, high-frequency, and reusable launch systems.
• Accelerating the development of fully reusable rockets is essential for maintaining global competitiveness.

Rising Space Debris and Orbital Congestion

• The increase in satellite launches has led to growing space debris, posing risks to operational satellites and future missions.
• India lacks an independent space traffic management system, making it dependent on international agencies for debris tracking.
• With thousands of satellites planned for Low Earth Orbit (LEO) mega constellations, risks of collisions and orbital congestion are expected to rise, necessitating urgent regulatory and technological solutions.
• In 2023, 3,143 objects from 212 launches and on-orbit breakups were added to the space object population, underscoring the escalating debris threat.

Delayed Implementation of Space Policy and Regulatory Frameworks

• The New Space Policy 2023 was a significant step in opening the sector to private players, but implementation delays and bureaucratic hurdles have slowed its impact.
• IN-SPACe (Indian National Space Promotion and Authorization Center), responsible for regulating and facilitating private sector participation, is still refining its framework, creating uncertainty for startups and investors.
• A comprehensive legal framework covering space activities, satellite licensing, and liability is necessary to attract global investments.
• India has over 150 space startups, but most face funding challenges, regulatory roadblocks, and limited global market access.

Cybersecurity Threats and Space Asset Protection

• With growing reliance on satellites for communication, defense, and navigation, cyber threats targeting space assets pose serious national security risks.
• India lacks a dedicated Space Cybersecurity Command to counter satellite hacking, GPS spoofing, and space-based cyber espionage.
• ISRO currently does not have an autonomous cybersecurity division, making its satellites potential targets for hostile cyber intrusions.

Climate Change Impact on Space Infrastructure

• Extreme weather conditions, rising temperatures, and increasing humidity pose threats to ISRO’s launch sites and ground stations.
• Coastal launch sites like Sriharikota (SHAR) and Thumba are vulnerable to cyclones and sea-level rise, which could disrupt launch schedules and infrastructure stability.
• Implementing climate adaptation strategies, including reinforced launch complexes and alternative inland launch sites, is essential to mitigate risks.

Growing Competition from Emerging Space Powers

• India faces rising competition from China, UAE, and South Korea, which are making rapid advancements in lunar exploration, deep-space missions, and private sector-led space initiatives.
• China’s Chang’e program aims for lunar colonization by 2035, while the UAE’s Mars and Moon missions are attracting global collaborations.
• To maintain leadership, India must expedite Chandrayaan-4, Venus missions, and interplanetary exploration projects.

Delays in Strategic Military Space Capabilities

• India has been slow in developing dedicated military space assets, lagging behind China’s Space Force and its advanced weaponized satellite capabilities.
• While India possesses anti-satellite (ASAT) technology, it lacks dedicated space-based missile defense and electronic warfare satellites.
• Establishing an integrated space command and a dedicated defense satellite constellation is crucial for national security.
• China operates over 300 military satellites, whereas India has far fewer for defense and surveillance purposes.

By addressing these challenges, India can strengthen its space sector, enhance global competitiveness, and safeguard its long-term strategic interests in space exploration and defense.
