Commercial Crew Program Milestones

CCDev1

2010NASA kicks off Commercial Crew Development Round 1 (CCDev1) by funding Sierra Nevada $20 million, Boeing $18 million, United Launch Alliance (ULA) $6.7 million, Blue Origin $3.7 million and Paragon Space Development Corp $1.4 million under cost-share Space Act Agreements. Credit: Boeing

CCDev2

2011CCDev2 cost-share agreements awarded to Boeing $92.3 million, Sierra Nevada $80 million, SpaceX $75 million and Blue Origin $22 million. NASA also signs unfunded Space Act Agreements with ULA and Excalibur Almaz and later adds $25.6 million to Sierra Nevada and $20.6 million to Boeing via optional contract milestones.

Certification Products Contracts

2012NASA whittles down the competition to provide crew flight services to three companies. Boeing gets $460 million, SpaceX $440 million and Sierra Nevada $212.5 million to support development of integrated systems under round three of the program. SpaceX and Boeing each are awarded another $20 million and Sierra Nevada an extra $15 million when NASA exercises options for additional milestones. The companies also receive about $10 million each under Certification Products Contracts to develop data products to implement the agency's flight safety and performance requirements. Credit: NASA

Transportation Capability Contracts

2014Boeing and SpaceX are selected for Commercial Crew Transportation Capability contracts, worth up to $4.2 billion and $2.6 billion, respectively, that cover two flight tests and up to six operational missions per company. Credit: NASA

Crew Cadre

August 2015NASA selects four astronauts, called the Crew Cadre, who embed themselves at both SpaceX and Boeing during vehicle final designs. After three years, Bob Behnken and Doug Hurley are assigned to the crewed flight test of Dragon, while Sunita Williams and Eric Boe are assigned to Starliner missions. Credit: NASA

Four More Astronauts

Static Test Fire On Falcon 9

April 2020SpaceX conducts a static test fire of the Falcon 9 rocket being prepared for the Demo-2 crewed flight test. The mission, scheduled for launch on May 27, will be the first U.S. human orbital flight since the end of the shuttle program in July 2011. Credit: SpaceX
