We're living in a golden age of reusable rockets, with companies like SpaceX launching missions into space almost daily. Yet, counterintuitively, NASA is spending more on launches now than it did 30 years ago. A forthcoming study in the journal Acta Astronautica sheds light on this puzzling trend.

In today's launch landscape, SpaceX has become a dominant force, routinely sending batches of Starlink satellites into orbit, while also taking on a hefty share of NASA's missions. While one might expect that the increase in supply should lead to falling prices, the reality is far more complicated.

The Demand Dilemma

Despite the routine nature of space launches, demand is at an all-time high. SpaceX is not only catering to NASA but also to the US military, which has ramped up its space missions significantly. NASA's missions form only a small fraction of the busy launch schedule filled with commercial satellites and other SpaceX projects, primarily Starlink and its military counterpart, Starshield.

Cost vs. Expenditures

According to financial analyses by NASA's own strategic investments analyst, Moon Kim, costs for NASA's launch services have risen. Over the years 1996 to 2024, adjusting for inflation, NASA's launch service costs have increased by an average of nearly 3% annually. Alarmingly, the introduction of SpaceX as a launch service provider has not shifted this cost trend.

Before SpaceX, NASA relied primarily on United Launch Alliance (ULA) for heavy satellite launches, but following the debut of SpaceX’s Falcon 9 in 2016, hopes were high that costs would decline sharply. After all, reusability—wherein the first stage of a rocket can be recovered and reused—was touted as a game changer. SpaceX has made it possible to recover 70% of launch costs through its reusability model.

The Price Tag Chronicles

However, in recent years, SpaceX has gradually increased prices for Falcon 9 launches—from $62 million to $70 million—indicating a significant markup despite their cost-saving innovations. This raises questions about the supposed efficiencies expected from privatization that were supposed to lead to lower consumer prices.

Kim's analysis points out that while privatization was anticipated to enhance competition and drive down costs, this hasn't materialized as expected. In fact, government entities like NASA often pay more than commercial customers for launch services, ensuring they receive priority on launch schedules and additional oversight.

A Comparison Through Time and Value

Examining historical launch contracts offers insight into these rising costs. For example, launching the Mars Odyssey in 2001 would equate to about $96 million today. In stark contrast, missions like the OSIRIS-REx asteroid mission in 2016 were launched on Atlas V rockets at a staggering cost of $252 million, showcasing a clear upward trend in launch costs post-ULA's formation.

Even SpaceX's launches have seen increased price ranges. NASA continues to book Falcon 9 launches for upcoming missions at average prices near or even higher than the market rates they were paying 20 years ago.

Future Implications and a Competitive Landscape

Though NASA is indeed paying SpaceX less than it would have under ULA contracts a decade ago, the dramatic cost increases pose ongoing challenges. As competition in the launch market remains limited, NASA has looked on as ULA's Atlas V nears retirement while newer rockets from ULA and Blue Origin get set to enter the fray.

The future of launch costs will likely emerge once these new players establish themselves. While NASA's launch costs hover around $103 million for upcoming missions, we will have to wait and see if competition truly drives prices down.

In the end, despite the hype surrounding reusable rockets and soaring launch frequencies, NASA's ever-growing expenditures serve as a stark reminder that navigating space is no cheap endeavor.
