Engineers and safety specialists from NASA and Space Exploration Technologies (SpaceX) met in late October to review the safety of the Dragon spacecraft and Falcon 9 rocket being developed to launch humans into low-Earth orbit later this decade.

The detailed overview of safety practices the company is implementing was a major milestone for SpaceX under a funded Space Act Agreement with NASA's Commercial Crew Program (CCP).

SpaceX is one of NASA's commercial partners working to develop a new generation of U.S. spacecraft and rockets capable of transporting humans to and from low-Earth orbit from American soil. NASA intends to use new commercial systems to fly U.S. astronauts to and from the International Space Station within the next four years.

A team of NASA engineers went to SpaceX headquarters for two days of detailed presentations and question-and-answer sessions that reviewed the company's safety practices.

"The milestone is not the end of the safety discussion, it's really the beginning," said Jon Cowart, deputy manager of the NASA Partnership Integration Team for CCP. "Because we've been doing this for so long, we all have a pretty good idea of what works and what doesn't and how safety processes can be strengthened to increase our confidence in the system."

Teams from NASA and SpaceX are working closely together to make sure the innovative technologies employed meet the rigorous requirements that come with flying crews in space.

"We greatly appreciate NASA's support and feedback throughout this process," said Garrett Reisman, commercial crew project manager at SpaceX and a former astronaut. "Together we are taking all the necessary steps to make Dragon the safest, most reliable spacecraft ever flown."

SpaceX already has flown several cargo missions to the space station using its Dragon spacecraft and Falcon 9 rocket, but those spacecraft have not yet transported astronauts. Through NASA's Commercial Crew Integrated Capability (CCiCap) initiative, the company is deep into the design process of the integrated crew-capable Falcon 9 and Dragon spacecraft.

SpaceX plans to test its launch abort system next year at Cape Canaveral Air Force Station in Florida. Two flight tests will demonstrate the ability the Dragon spacecraft abort system to lift an uncrewed spacecraft clear of a simulated emergency.

The first test will simulate an abort from the pad prior to launch in the second quarter of 2014. The second test, targeted for the third quarter of 2014, calls for the spacecraft to separate from a Falcon 9 booster in flight and parachute safely into the Atlantic Ocean. The company is building the spacecraft for the flight tests and manufacturing of the rocket is expected to begin shortly.

This safety review was the ninth milestone for SpaceX under CCiCap. The company is on track to complete all 15 of its CCiCap milestones by the third quarter of 2014. All of NASA's industry partners, including SpaceX, continue to meet their established milestones in developing commercial crew transportation capabilities.
