In 2006, NASA selected SpaceX as one of two companies (alongside Rocketplane Kistler, later replaced by Orbital Sciences) to receive Commercial Orbital Transportation Services funding, aimed at demonstrating private cargo delivery to the International Space Station.[1][2] Rather than NASA specifying a design and paying for its development regardless of outcome, COTS paid fixed amounts tied to specific technical milestones — engine tests, demonstration flights, and berthing with the station — with SpaceX retaining intellectual property rights to the resulting Falcon 9 rocket and Dragon spacecraft.[1][2]
01
At a Glance
SpaceX's relationship with NASA has been central to the company's survival and growth since 2006, when it won a Commercial Orbital Transportation Services (COTS) award to help develop cargo delivery capability to the International Space Station. Unlike traditional cost-plus defense contracts, NASA's COTS and subsequent Commercial Resupply Services (CRS) and Commercial Crew Program (CCP) contracts were structured around fixed prices and technical milestones, an approach that let a young company access public funding and NASA engineering expertise while retaining ownership of the hardware it developed. The partnership scaled from cargo runs in 2012 to crewed astronaut flights in 2020, transforming SpaceX into NASA's primary means of reaching the space station.

03
Commercial Resupply Services (CRS)
Following successful COTS demonstration flights, including Dragon's first berthing with the space station in 2012, NASA awarded SpaceX a Commercial Resupply Services contract in December 2008 worth about $1.6 billion for at least twelve cargo missions — funding secured at a moment when both SpaceX and Tesla were near financial collapse.[3][4] The CRS contracts (CRS-1 and a later CRS-2 follow-on) have since funded dozens of operational cargo flights, becoming a reliable long-term revenue base for SpaceX during the years it was investing heavily in reusability and Starship development.[4][5]
04
Commercial Crew Program (CCP)
NASA extended the same public-private, milestone-based model to astronaut transport through its Commercial Crew Program, awarding SpaceX a contract in 2014 (alongside Boeing) to develop a crew-rated version of Dragon.[5][6] After a multi-year certification process including uncrewed and in-flight abort tests, SpaceX's Crew Dragon carried NASA astronauts Doug Hurley and Bob Behnken to the space station in May 2020 on the Demo-2 mission, restoring the United States' ability to launch its own astronauts for the first time since the Space Shuttle's retirement in 2011.[5][6] SpaceX has since flown numerous operational Crew Dragon rotations to the station under the program.[6]
05
Why the Model Mattered
Analysts and NASA officials have credited the COTS/CRS/CCP approach with substantially lowering the cost of reaching orbit compared with traditional government-owned, cost-plus-contracted vehicles, while also creating a commercial launch industry that now serves customers well beyond NASA.[2][6] The model has since been extended to other programs, including NASA's Human Landing System contract for Starship's lunar variant, continuing the pattern of NASA funding and expertise combined with SpaceX's private capital and engineering execution.[6]

Frequently Asked Questions
What was NASA's COTS program?
+
Commercial Orbital Transportation Services was a NASA program starting in 2006 that paid fixed, milestone-based awards to private companies, including SpaceX, to develop cargo delivery capability to the International Space Station, letting companies retain ownership of the resulting hardware.
How much was SpaceX's first NASA cargo contract worth?
+
SpaceX's December 2008 Commercial Resupply Services contract was worth about $1.6 billion for at least twelve cargo missions, funding awarded at a moment when the company was financially struggling.
When did SpaceX first fly NASA astronauts?
+
In May 2020, on the Demo-2 mission, when Crew Dragon carried NASA astronauts Doug Hurley and Bob Behnken to the space station under the Commercial Crew Program.
How is a NASA COTS-style contract different from a traditional government contract?
+
Traditional cost-plus contracts pay a contractor's costs plus a fee regardless of outcome; COTS-style contracts pay fixed amounts only when specific technical milestones are met, with the company owning the resulting technology.
Has the NASA-SpaceX contract model been used elsewhere?
+
Yes. NASA extended the same public-private model to its Human Landing System program, awarding SpaceX a contract to develop a lunar version of Starship for the Artemis program.
