How NASA’s COTS program reshaped space funding and gave SpaceX the runway to become what it is today.
In light of the SpaceX IPO this Friday, I was compelled to trace how the company got here. The story is not only about technological milestones or the leadership of Elon Musk. It is also about a fundamental transformation in how the United States funds space exploration.
The U.S. space program became increasingly promoted during the Cold War following the Soviet Union’s launch of Sputnik 1, the world’s first artificial Earth satellite. In response, NASA was created in 1958. The Apollo program became NASA’s first crowning achievement, reaching a point when the agency received 4.4% of total federal spending, the highest percentage in its history. Today, NASA receives approximately 0.5%.
As the threat posed by the Soviet Union diminished, space exploration became less of a national priority. The failures and tragedies of the Challenger and Columbia disasters also led the government to reevaluate the Space Shuttle program and explore more efficient approaches to accessing space.
By the early 2000s, two schools of thought had emerged around how to close the space-access gap.
- The first called for a return to a centralized, government-led program with ambitions comparable to those of the Apollo era. This approach was represented by the Constellation program, which envisioned a rocket similar in size to the Saturn V, a lunar lander, and a vehicle capable of transporting crew and cargo to the International Space Station. Its broader objective was to return humans to the Moon, establish a sustained lunar presence, and use it as a stepping stone to Mars.
- The second approach sought to create a larger role for the private sector. This philosophy was advanced through initiatives such as the Commercial Space Launch Amendments Act of 2004 and President George W. Bush’s Aldridge Commission. One of the commission’s recommendations was for NASA to purchase services from private companies rather than own and operate every component of the space program itself.
This approach initially focused on the narrower objective of resupplying the International Space Station. In 2005, NASA requested $500 million for a new program called Commercial Orbital Transportation Services, or COTS. The program put the commercial-space thesis to the test by challenging private companies to develop the capabilities and services needed to reach space, while potentially opening entirely new markets.
Before COTS, NASA primarily contracted through a set of rules known as the Federal Acquisition Regulation, or FAR. Under this system, the government often funded technology development on a “cost-plus” basis, covering a contractor’s expenses and providing an additional profit margin.
This cost-covering model insulated private companies from much of the financial risk, but it also limited the potential upside. Boeing, Lockheed, and Northrop participated in these programs for decades. Smaller and earlier-stage companies, however, often found the FAR process difficult to manage.
NASA maintained extensive oversight of design, development, and manufacturing, requiring significant government documentation and supervision. Companies also had little incentive to control costs because their margins were largely guaranteed.
COTS changed several core features of this model:
- It used fixed-price agreements rather than reimbursing costs plus a guaranteed margin. This placed more financial risk on the companies but gave them a stronger incentive to operate efficiently.
- NASA provided insight rather than direct oversight. Giving companies greater control over their own operations allowed them to develop and scale technologies through their own methods.
- Companies were permitted to retain the intellectual property rights to the technologies they developed, introducing a more business-oriented approach to government space funding.
In 2006, one of the first COTS agreements was awarded to SpaceX. Elon Musk’s company went on to achieve several major milestones with the help of approximately $400 million in early NASA funding.
- In 2010, SpaceX launched the Falcon 9 and demonstrated its ability to deliver spacecraft and cargo into orbit.
- In 2012, the Dragon capsule became the first commercial spacecraft to reach and dock with the International Space Station, fulfilling a central objective of SpaceX’s COTS agreement.
- In 2015, SpaceX successfully landed the first stage of an orbital-class rocket. This achievement laid the foundation for partially reusable launch systems and helped dramatically reduce the cost of reaching space.
In its early days, SpaceX was losing rockets and rapidly burning through cash. Although the company had raised roughly $450 million in private capital, the nearly $400 million it received through COTS arrived at a crucial moment and represented half of the company’s costs. The company may have taken a very different path without COTS, and the program accelerated SpaceX’s progress and became one of the most consequential government investments in the history of commercial spaceflight.
