Commercial Crew Development (CCDev) is a human spaceflight development program that is funded by the U.S. government and administered by NASA. CCDev will result in US and international astronauts flying to the International Space Station (ISS) on privately operated crew vehicles.
Operational contracts to fly astronauts were awarded in September 2014 to SpaceX and Boeing. Test flights of Dragon 2 and CST-100 are scheduled for 2019. Pending completion of the demonstration flights, each company is contracted to supply six flights to ISS between 2019 and 2024. The first group of astronauts was announced on 3 August 2018.
Key high-level requirements for the Commercial Crew vehicles include:
- Safely deliver and return four crew members and their equipment to the International Space Station (ISS)
- Provide assured crew return in the event of an emergency
- Serve as a 24-hour safe haven in the event of an emergency
- Capable of remaining docked to the station for 210 days
Development program overview
After the retirement of STS in 2011, the US had no domestic vehicles capable of launching astronauts to space. The next major human spaceflight initiative will launch in 2021 as Artemis 2 on the Space Launch System.
In the meantime, NASA continued to send astronauts to the ISS on Soyuz spacecraft seats purchased from Russia. The price has varied over time, with the batch of seats from 2016 to 2017 costing 70.7 million per passenger per flight. The intent of CCDev is to develop safe and reliable commercial ISS crew launch capabilities to replace the Soyuz flights. CCDev follows Commercial Orbital Transportation Services (COTS), an ISS commercial cargo program. CCDec contracts are issued for fixed-price, pay-for-performance milestones.
NASA awarded development funds to five companies under CCDev 1:
- Blue Origin: $3.7M for a 'pusher' Launch Abort System (LAS) and composite pressure vessels.
- Boeing: $18M for development of the CST-100
- Paragon Space Development Corporation: $1.4M for a plug-and-play environmental control and life support system (ECLSS) Air Revitalization System (ARS) Engineering Development Unit.
- Sierra Nevada Corporation: $20M for development of the Dream Chaser
- United Launch Alliance: $6.7M for an Emergency Detection System (EDS) for human-rating Atlas V
On 18 April 2011, NASA awarded nearly $270 million to four companies for developing U.S. vehicles that could fly astronauts after the Space Shuttle fleet's retirement.
- Blue Origin: $22 million. Technologies in support of a biconic nose cone design orbital vehicle, including launch abort system liquid oxygen/liquid hydrogen engines.
- Sierra Nevada Corporation: $80 million. Dream Chaser
- SpaceX: $75 million. Dragon 2 integrated launch abort system
- Boeing: $92.3 million. Additional CST-100 development
Proposals selected without NASA funding:
- United Launch Alliance: extend development work on human-rating the Atlas V
- Alliant Techsystems (ATK) and Astrium proposed development of Liberty. NASA will share expertise and technology.
- Excalibur Almaz Inc. was developing a crewed system with modernized Soviet-era hardware intended for tourism flights to orbit. An unfunded Space Act Agreement to establish a framework to further develop EAI's spacecraft concept for low Earth orbit crew transportation.
Proposals not selected:
- Orbital Sciences proposed the Prometheus lifting-body spaceplane vehicle
- Paragon Space Development Corporation proposed additional development of the Commercial Crew Transport-Air Revitalization System.
- t/Space proposed a reusable eight-person crew or cargo transfer spacecraft
- United Space Alliance proposed to commercially fly the two remaining Space Shuttle vehicles.
Commercial Crew integrated Capability (CCiCap) was originally called CCDev 3. For this phase of the program, NASA wanted proposals to be complete, end-to-end concepts of operation, including spacecraft, launch vehicles, launch services, ground and mission operations, and recovery. In September 2011, NASA released a draft request for proposals (RFP).
The selected proposals were announced 3 August 2012:
- Sierra Nevada Corporation: $212.5 million. Dream Chaser/Atlas V
- SpaceX: $440 million. Dragon 2/Falcon 9
- Boeing: $460 million. CST-100/Atlas V
CPC phase 1
The first phase of the Certification Products Contract (CPC) involved the development of a certification plan with engineering standards, tests, and analyses.
Winners of funding of phase 1 of the CPC, announced on December 10, 2012, were:
- Sierra Nevada Corporation: $10 million
- SpaceX: $9.6 million
- Boeing: $9.9 million
CCtCap - crew flights awarded
The Commercial Crew Transportation Capability (CCtCap) is the second phase of the CPC and included the final development, testing and verifications to allow crewed demonstration flights to the ISS.  NASA issued the draft CCtCap contract's Request For Proposals (RFP) on 19 July 2013 with a response date of 15 August 2013.
On 16 September 2014, NASA announced that Boeing and SpaceX had received contracts to provide crewed launch services to the ISS. Boeing could receive up to US$4.2 billion, while SpaceX could receive up to US$2.6 billion.
As the spacecraft entered the testing and production phase, technical issues have also caused delays.
CST-100 valve issue
Crew Dragon explosion
On 20 April 2019, an issue arose during a static fire test of Crew Dragon. The accident destroyed the capsule which was planned to be used for the In-Flight Abort Test (IFAT). SpaceX confirmed that the capsule exploded. NASA has stated that the explosion will delay the planned IFAT and crewed orbital test.
NASA has ordered twelve operational missions to deliver astronauts to the International Space Station, six with each supplier. Astronaut selections for the first four missions were announced on August 2, 2018.

For the fiscal year (FY) 2011 budget, US$500 million was requested for the CCDev program, but Congress granted only $270 million. For the FY 2012 budget, $850 million was requested and $406 million approved. For the FY 2013 budget, 830 million was requested and $488 million approved. For the FY 2014 budget, $821 million was requested and $696 million approved. In FY 2015, $848 million was requested and $805 million, or 95%, was approved.
The funding of all commercial crew contractors for each phase of the CCP program is as follows—CCtCap values are maxima and include post-development operational flights.[quantify]
