1. How Has ISRO’s Technical Approach Created a Unique Space Program?

1.1 ISRO’s Frugal Innovation Model Delivers Exceptional Value Despite Resource Constraints.

ISRO’s approach to space exploration stands out globally for its remarkable cost-effectiveness. When India’s Mangalyaan orbiter reached Mars in 2014, it did so at a budget of just $74 million—less than the production cost of the Hollywood space movie “Gravity.” This was the result of a deliberate philosophy I’ve seen ISRO perfect over decades.

The agency’s frugal innovation model rests on several key principles:

• Maximizing existing infrastructure rather than building new facilities for each mission
• Employing commercial off-the-shelf components when possible instead of custom-designing everything
• Maintaining smaller, more agile engineering teams with clear accountability
• Designing missions with focused scientific objectives rather than carrying multiple complex payloads

ISRO’s pragmatic “mission-in-phases” approach allows them to build capabilities incrementally. Rather than attempting technological leaps, they systematically expand their expertise through carefully planned mission sequences. This reduces risk while steadily advancing capabilities—a strategy particularly evident in their lunar program progression from Chandrayaan-1 to Chandrayaan-3.

Their technical architecture emphasizes standardization across platforms. The PSLV launch vehicle family shares numerous components, while satellite buses ↗ like the I-1K, I-2K, I-3K, I-1K4, and I-3K6 provide standardized platforms that can be adapted for various missions.

This approach delivers exceptional value while building indigenous capabilities—proving that resource constraints can drive innovation rather than limit ambition.

1.2 Strategic Launch Vehicle Evolution Demonstrates Methodical Capability Development.

ISRO’s launch vehicle program represents one of the clearest examples of India’s methodical approach to space capability development. Rather than attempting technological leaps, ISRO has followed a deliberate step-by-step evolution that prioritizes reliability, cost-effectiveness, and mission-specific functionality.

The journey began with the modest SLV-3 in the 1980s, capable of lifting just 40kg to low Earth orbit. This seemingly humble start provided crucial experience in rocket design, propulsion systems, and launch operations that formed the foundation for all future developments.

The real breakthrough came with the Polar Satellite Launch Vehicle (PSLV), which has become ISRO’s undisputed workhorse with over 50 successful missions and a reliability rate exceeding 95%. The PSLV’s versatility allows it to deploy satellites to various orbits, making it particularly attractive for international customers seeking cost-effective launch options for small to medium satellites.

The GSLV program represented ISRO’s next major challenge—developing indigenous cryogenic engine technology after US sanctions prevented technology transfer from Russia. Despite setbacks, ISRO persevered to create the CE-7.5 cryogenic engine ↗ , demonstrating the organization’s commitment to self-reliance even when facing significant obstacles.

Today’s focus on the Small Satellite Launch Vehicle (SSLV) and reusable launch technology shows ISRO’s continued pragmatism—developing capabilities that address specific market needs while maintaining its competitive advantage in cost-effective access to space.

1.3 Satellite Technology Prioritizes Practical Applications with Immediate Societal Benefits.

ISRO’s satellite program stands out globally for its unwavering focus on practical applications that deliver immediate benefits to Indian society. Unlike space agencies that prioritize prestige projects, ISRO has deliberately developed satellite platforms that address India’s unique challenges.

The agency’s Earth observation satellites exemplify this approach. The Resourcesat series ↗ provides critical data for agricultural monitoring, allowing farmers and officials to track crop health, predict yields, and manage resources more effectively. During the 2018 Kerala floods, ISRO’s Cartosat-2 imagery ↗ proved invaluable for disaster response teams, helping coordinate rescue operations and assess damage in real-time.

ISRO’s satellite design philosophy consistently demonstrates dual-purpose thinking:

• Remote sensing satellites serve both strategic defense needs and civilian applications
• Communication satellites strengthen sovereignty while connecting remote villages
• Weather monitoring systems support military operations and provide farmers with crucial forecasts

This table illustrates ISRO’s systematic capability enhancement while maintaining cost-effectiveness:

What’s particularly impressive is how ISRO has achieved these capabilities at approximately one-tenth the cost of comparable international missions. The agency’s frugal engineering approach doesn’t sacrifice reliability—it enhances it by focusing on robust, proven technologies rather than cutting-edge experiments.

This pragmatic approach has created a virtuous cycle: practical applications generate public support, which enables sustainable funding, allowing for systematic capability improvements that deliver even greater societal benefits.

Key Takeaways

2. How Is ISRO Transitioning to a Mixed Ecosystem Model?

2.1 Organizational Restructuring Creates Clear Separation Between Research and Commercial Activities.

ISRO’s organizational architecture is undergoing its most significant transformation since the agency’s founding in 1969. The restructuring creates three distinct pillars with clear mandates, replacing the previous monolithic structure where ISRO handled everything from research to commercialization.

The new ecosystem ↗ now features:

• ISRO: Focuses on core R&D, technology development, and complex scientific missions
• NewSpace India Limited (NSIL): Operates as the commercial arm handling technology transfer and routine space services
• IN-SPACe: Serves as the regulatory body overseeing private sector participation
• Department of Space: Shall oversee the distribution of responsibilities outlined in this policy

This separation addresses what had become a fundamental conflict of interest. Previously, ISRO simultaneously developed technologies, commercialized them, and regulated the sector—creating inefficiencies and limiting private sector growth.

As K. Sivan, former ISRO Chairman, pointed out ↗ , the space-based economy is expected to “explode” in the coming years, in India as well as abroad, setting up NSIL and IN-SPACe amid that scenario is a majorly significant and much needed step.

The restructuring has tangible benefits:

The transformation hasn’t been without friction. Some veteran ISRO scientists ↗ initially viewed the changes with skepticism, concerned about fragmenting the organization’s unified culture. However, the restructuring is already showing results ↗ in 2021 with over 100 space startups now active in India compared to fewer than 10 in 2019.

For researchers and scientists within ISRO, this means more focused work environments with clearer objectives. For India’s space program as a whole, it represents a maturation that mirrors successful models seen in other spacefaring nations.

2.2 Developing Regulatory Frameworks Will Enable Further Private Sector Participation.

India’s space regulatory environment is undergoing a significant transformation, with the pending Space Activities Bill ↗ representing the cornerstone of this evolution. This legislation aims to create a comprehensive legal framework that shifts from ISRO’s historically restrictive approach to an enabling regulatory environment for commercial space activities.

The current regulatory landscape presents several challenges:

• Absence of clear licensing procedures for private launch vehicles
• Undefined liability frameworks for commercial space operations
• Lack of clarity on intellectual property rights for space-based innovations
• Regulatory ambiguity regarding spectrum allocation for private satellite operators

“The regulatory gaps aren’t just administrative hurdles—they’re strategic challenges that directly impact India’s competitiveness in the global space economy,” notes a recent NITI Aayog assessment.

The proposed regulatory framework aims to address these issues while balancing multiple priorities:

ISRO and IN-SPACe are working collaboratively to develop these frameworks, with significant input from industry stakeholders. The process includes benchmarking against successful models from other spacefaring nations while adapting to India’s unique context.

A particularly challenging aspect involves aligning with international treaties while advocating for developing nations’ interests in global space governance. India’s position on space resource utilization and debris mitigation reflects this balancing act, as it works to ensure equitable access while supporting commercial development.

For private investors, these regulatory developments signal India’s commitment to creating a predictable environment for space ventures, though the pace of implementation remains a concern for many industry participants.

2.3 Business Model Evolution Addresses Strategic Contradictions in Organizational Focus.

ISRO has been navigating a fundamental business contradiction for years. On one hand, it serves as India’s national space agency with responsibilities for strategic missions, scientific research, and societal applications. On the other, it competes in the global commercial launch and satellite markets where agility and cost-effectiveness are paramount.

This dual mandate creates organizational tensions that ISRO is addressing through structural separation. The creation of NewSpace India Limited (NSIL) in 2019 ↗ represents the most visible manifestation of this strategy. NSIL now handles commercial activities while ISRO focuses on R&D, technology development, and national priority missions.

The business model evolution addresses three key contradictions:

• Innovation vs. Oversight - Commercial space requires rapid iteration and risk-taking, while government programs demand rigorous oversight and accountability
• Cost leadership vs. Technology leadership - Maintaining ISRO’s renowned cost advantage while investing in cutting-edge capabilities
• National priorities vs. Global competitiveness - Balancing domestic needs against international market opportunities

This separation allows for differentiated approaches to funding, risk management, and operational tempo:

The transition isn’t without challenges. Resource allocation decisions, intellectual property management, and cultural differences between the government and commercial entities create ongoing friction. However, the structural separation provides a framework for resolving these tensions rather than allowing them to paralyze the organization.

ISRO’s phased investment strategy now allows it to maintain cost leadership in established capabilities while selectively investing in advanced technologies through targeted R&D programs and strategic partnerships with private sector entities.
