India's Space Program Faces a Costly Reality Check

India's space program has long been lauded for its frugal engineering prowess, with historic missions like Chandrayaan showcasing the country's ability to deliver budget-friendly space exploration. However, a recent study has turned the spotlight on India's space program, revealing a stark contrast between its overall mission economy and the high per-kilogram cost of launching payloads to Low Earth Orbit.

The study, conducted by researchers from the University of Cambridge and Politecnico di Torino, analyzed over 6,740 rocket launches spanning from 1960 to 2025. According to the findings, India's estimated cost of delivering a kilogram of payload to Low Earth Orbit stood at $13,302 in 2025. This figure places India at the higher end of the spectrum compared to other major spacefaring nations and well above the global average of $3,868 per kilogram.

The researchers attribute the higher unit cost to structural and operational factors, including payload capacity dynamics and launch frequency. Historically, the Indian Space Research Organisation (ISRO) has relied heavily on smaller workhorse launch vehicles, which are exceptionally reliable but distribute fixed infrastructure and operational costs across smaller payload masses, naturally elevating the cost-per-kilogram calculation.

Furthermore, the study highlights the concept of the "experience curve," where production and launch costs decline exponentially with cumulative repetitions. While nations like the United States have scaled up flight cadences significantly over the last decade, driven in part by commercial heavy-hitters like SpaceX, India's overall launch frequency has not yet reached the scale required to aggressively drive down unit costs through cumulative repetition.

The findings of the study provide critical data points for emerging commercial entities like IN-SPACe and NewSpace India Limited (NSIL), emphasizing the need to scale up launch cadences and expand payload capacities to enhance long-term competitiveness in the global commercial space market. As access to space transitions into a core pillar of national security and modern commercial infrastructure, India's space program must adapt to remain competitive in a rapidly evolving global space economy.

The study's implications are far-reaching, with potential implications for India's space program and its future in the global space market. As the country continues to push the boundaries of space exploration, it will be crucial to address the structural and operational factors contributing to its high per-kilogram cost. By doing so, India can ensure its continued competitiveness in the global space market and remain a major player in the rapidly evolving space economy.

A Costly Reality Check

India's space program has long been lauded for its frugal engineering prowess, but a recent study has turned the spotlight on its high per-kilogram cost of launching payloads to Low Earth Orbit.

The Experience Curve

The study highlights the concept of the experience curve, where production and launch costs decline exponentially with cumulative repetitions. While nations like the United States have scaled up flight cadences significantly over the last decade, India's overall launch frequency has not yet reached the scale required to aggressively drive down unit costs through cumulative repetition.

Launch Frequency and Unit Costs

The study shows a clear relationship between launch frequency and unit costs, with India's data points at the lower end of the spectrum. This highlights the need for India to scale up its launch frequency and expand its payload capacities to enhance long-term competitiveness in the global commercial space market.

Emerging Commercial Entities

The findings of the study provide critical data points for emerging commercial entities like IN-SPACe and NewSpace India Limited (NSIL), emphasizing the need to scale up launch cadences and expand payload capacities to enhance long-term competitiveness in the global commercial space market.
