What Happened to NASA Commercial Crew Program?
The NASA Commercial Crew Program (CCP) was established in 2011 to foster the development of privately operated spacecraft for transporting astronauts to and from the International Space Station (ISS), ending U.S. reliance on Russian Soyuz vehicles. While SpaceX's Crew Dragon has successfully conducted numerous operational missions since 2020, Boeing's Starliner program has faced significant delays and technical challenges, including a critical crew flight test in 2024 that resulted in astronauts returning on a different spacecraft. As of August 2026, SpaceX continues regular crew rotations, while Boeing is preparing for an uncrewed Starliner test flight to address persistent issues, with its future role in crew transport being re-evaluated.
Quick Answer
The NASA Commercial Crew Program is an ongoing initiative that partners with private companies to provide crew transportation to the International Space Station. SpaceX's Crew Dragon has been highly successful, regularly ferrying astronauts since 2020 and completing its 12th operational mission in February 2026. In contrast, Boeing's Starliner has experienced substantial delays and technical setbacks, including a problematic crew flight test in June 2024 that led to its astronauts returning on a SpaceX vehicle in March 2025. As of August 2026, Starliner is slated for an uncrewed cargo test flight no earlier than April 2026 to resolve propulsion issues, with its contract modified and its long-term role in low-Earth orbit being re-evaluated.

Boeing Starliner Orbital Flight Test 2 (OFT-2) Success
Boeing's second uncrewed Starliner test flight (OFT-2) successfully docked with the ISS, completing key objectives after the previous failure and moving the program closer to crewed flight.
Boeing Starliner Crew Flight Test (CFT) Launches with Issues
Boeing launched its first crewed Starliner mission (CFT) with NASA astronauts Butch Wilmore and Suni Williams. However, the spacecraft experienced multiple helium leaks and thruster failures on approach to the ISS.
Starliner CFT Returns Uncrewed
After weeks of analysis regarding Starliner's propulsion issues, NASA decided to return the capsule to Earth uncrewed. Astronauts Wilmore and Williams remained on the ISS.
Wilmore and Williams Return on SpaceX Crew Dragon
NASA astronauts Butch Wilmore and Suni Williams, who had been stranded on the ISS since the Starliner CFT, returned to Earth aboard a SpaceX Crew Dragon, ending their 286-day stay.
SpaceX Crew-11 Launches
SpaceX launched its 11th operational Commercial Crew Program mission, Crew-11, carrying four astronauts to the International Space Station.
NASA and Boeing Modify Starliner Contract, Next Flight Uncrewed
NASA and Boeing modified their Commercial Crew contract, reducing guaranteed Starliner missions from six to four. The next Starliner flight was announced to be uncrewed, targeting April 2026.
SpaceX Crew-11 Returns Early Due to Medical Issue
SpaceX Crew-11 returned to Earth earlier than planned due to a medical situation involving astronaut Michael Fincke, who experienced a temporary inability to speak.
Starliner CFT Classified as Type A Mishap
NASA released an investigation report classifying the Boeing Starliner Crew Flight Test as a Type A mishap, the agency's most severe failure category, citing multiple deficiencies.
SpaceX Crew-12 Launches
SpaceX launched its 12th operational Commercial Crew Program mission, Crew-12, carrying four astronauts to the International Space Station, where they are currently serving.
Boeing Starliner-1 (Uncrewed Cargo) Targeted Launch
Boeing's next Starliner mission, Starliner-1, is targeted for no earlier than April 2026. This uncrewed flight will deliver cargo to the ISS and validate system upgrades following the CFT issues, serving as a test for certification.
Boeing Starliner's Evolving Role in LEO
Despite past setbacks, Boeing's Starliner is now positioned to play a greater role in the U.S. government's plans for Low Earth Orbit into the 2030s, as its future is being re-evaluated amidst questions about SpaceX's long-term strategy.

🔍Deep Dive Analysis
The NASA Commercial Crew Program (CCP) emerged in 2011 following the retirement of the Space Shuttle, aiming to restore independent U.S. human spaceflight capability and end reliance on Russian Soyuz spacecraft for ISS crew transport. The program shifted NASA's approach from government-developed vehicles to commercially operated services, fostering competition and innovation within the private aerospace industry.
NASA awarded Commercial Crew Transportation Capability (CCtCap) contracts in September 2014 to both SpaceX (up to $2.6 billion) for its Crew Dragon and Boeing (up to $4.2 billion) for its CST-100 Starliner, with expectations for both to be operational by 2017. SpaceX quickly advanced, conducting its uncrewed Demo-1 flight in March 2019 and the historic crewed Demo-2 flight in May 2020, marking the return of human spaceflight from U.S. soil. Since then, Crew Dragon has become the workhorse of ISS crew rotations, reliably transporting astronauts for NASA and commercial customers.
Boeing's Starliner program, however, encountered significant and persistent challenges. Its first uncrewed Orbital Flight Test (OFT-1) in December 2019 failed to reach the ISS due to software errors. While OFT-2 in May 2022 successfully docked with the ISS, the subsequent Crew Flight Test (CFT) in June 2024 proved to be a major setback. During CFT, Starliner experienced multiple helium leaks and thruster failures upon approach to the ISS, forcing astronauts Butch Wilmore and Suni Williams to remain aboard the station for an extended period. NASA ultimately decided to return the Starliner capsule uncrewed in September 2024, with Wilmore and Williams returning to Earth via a SpaceX Crew Dragon in March 2025.
In February 2026, NASA officially classified the Starliner CFT as a Type A mishap, its most severe failure category, citing hardware failures, qualification deficiencies, and leadership errors at both NASA and Boeing. Following this, in late 2025, NASA and Boeing modified their contract, reducing the number of guaranteed Starliner missions from six to four, with two optional flights. As of August 2026, Boeing is preparing for an uncrewed Starliner-1 mission, targeted for no earlier than April 2026, which will deliver cargo and validate system upgrades to address the propulsion issues. Despite its troubled past, there is an indication that Starliner could play a greater role in U.S. government plans for Low Earth Orbit into the 2030s, as questions arise regarding SpaceX's long-term plans. Meanwhile, SpaceX continues its operational cadence, with Crew-11 returning in January 2026 and Crew-12 launching in February 2026 and currently ongoing.
