A new study published in PNAS Nexus by Alessio Terzi and Francesco Nicoli offers an unprecedented analysis of over 4,400 orbital launches spanning six decades and multiple spacefaring nations. Their comprehensive dataset standardizes cost metrics to reveal a clear “experience curve” in space launch technology akin to learning curves observed in other high-tech sectors. For every doubling in cumulative payload sent into orbit, the cost per kilogram declines by approximately 21.2%, mirroring early-stage solar panel cost reductions.

This steep rate of cost reduction has profound implications for the future of space exploration and commercialization. If these trends continue, average launch costs could fall to around $1,600 per kilogram by 2030—bringing routine, economically viable access to Earth’s orbit within closer reach. The game changer in this trajectory could be SpaceX’s Starship. By leveraging full reusability and high flight cadence, Starship aims to push the cost per kilogram below the $1,000 threshold, potentially disrupting the entire launch market.

Nonetheless, realizing these reductions hinges on scaling up launch frequency significantly, something not without challenges. The study also highlights three critical factors that may slow or even reverse cost declines. The growing challenge of space debris increases risks and operational costs, complicating safe orbital access. Geopolitical fragmentation could fragment markets, with nations opting for independent launch capacities that reduce economies of scale. Additionally, heavy reliance on a single commercial western provider may introduce vulnerabilities to market disruption or policy changes.

Despite these headwinds, the trajectory toward cheaper orbital access appears robust and suggests an exciting era ahead for space-based industries. Lower launch costs could accelerate satellite deployment, space tourism, in-orbit services, and even lunar and Martian colonization efforts. This “learning curve” insight underscores the power of cumulative experience and innovation in driving down costs in one of humanity’s most complex and capital-intensive endeavors.

As launch providers refine reusable technologies and economies of scale grow, spaceflight may soon transform from an extraordinary technical feat into routine infrastructure. The era when orbiting a kilogram costs barely hundreds of dollars is on the horizon, fundamentally reshaping our relationship with space.

Drawing on the most comprehensive dataset ever assembled — covering 4,405 launches from 1960 to 2025 with over 330 rocket configurations across major spacefaring nations — the study provides a detailed analysis of cost trajectories in space launch technology. Last year, the average cost to reach low Earth orbit stood at about $3,868 per kilogram. This is projected to fall to $1,569 per kilogram by 2030, and potentially as low as $273 per kilogram by 2040.

The underlying mechanism identified is an “experience curve” effect, whereby every doubling of the cumulative payload launches corresponds to a 21.2% reduction in cost per kilogram. This rate of cost decline outpaces even the historic improvements in steamship freight during the Industrial Revolution and rapidly advancing solar photovoltaic technology. The comparison underscores the vast potential for economies of scale and technological innovation in space launch markets.

Interestingly, the research also reveals how geopolitical and economic shifts have influenced launch costs. The Cold War era saw relatively stable prices, but the fall of the Berlin Wall in 1989 marked the start of faster cost reductions. Increased involvement from commercial entities, notably SpaceX—which now accounts for roughly 80% of global annual payload to orbit—has sharply accelerated this trend, altering the space economy from a government-driven sphere into a competitive, market-based frontier.

While declining launch costs hold enormous promise, the study also cautions about risks posed by monopolistic control and rising geopolitical competition. The dominance of a single launch provider could stifle price competition and delay broader industrial growth in orbit. Nonetheless, expanded capacity is expected to nearly double from 4,900 tonnes in 2025 to over 9,100 tonnes by 2030, with projections reaching 32,000 tonnes by 2040.

The implications are vast. Lower costs could enable in-orbit factories producing advanced fiber optics and bioprinted organs, off-planet solar power stations, asteroid mining ventures, and even permanent lunar bases. This technological and economic leap positions space colonization and externalization of polluting industries as feasible ventures within the coming decades. The study concludes that the era of space launch is entering a new phase, where economics, trade, and innovation drive exponential growth and open up unprecedented opportunities for humanity beyond Earth.
