SpaceX Transitions to Third Commercial Crew Phase with NASA
WASHINGTON -- Space Exploration Technologies (SpaceX) has completed its first three performance milestones for NASA's Commercial Crew Integrated Capability (CCiCap) initiative, which is intended to lead to the availability of commercial human spaceflight services for government and commercial customers.
During the company's first milestone, a technical baseline review, NASA and SpaceX reviewed the Dragon spacecraft and Falcon 9 rocket for crew transportation to low-Earth orbit and discussed future plans for ground operations for crewed flights. The second milestone included a review of the company's plan to achieve the CCiCap milestones established during SpaceX's $440 million Space Act Agreement. SpaceX also presented the company's financial resources to support its co-investment in CCiCap.
At the company's headquarters in Hawthorne, Calif., on Oct. 29, SpaceX presented techniques it will use to design, build and test its integrated system during the third milestone, called an integrated systems requirements review. The company also provided NASA with the initial plans it would use for managing ground operations, launch, ascent, in-orbit operations, re-entry and landing should they begin transporting crews.
"These initial milestones are just the beginning of a very exciting endeavor with SpaceX." said Ed Mango, NASA's Commercial Crew Program manager. "We expect to see significant progress from our three CCiCap partners in a fairly short amount of time."
SpaceX also has completed its Space Act Agreement with NASA for the Commercial Crew Development Round 2 (CCDev2) initiative, the development phase that preceded CCiCap. During CCDev2, the company designed, developed and tested components of a launch abort system. A large hypergolic engine named SuperDraco would propel the Dragon spacecraft away from its rocket to save the crew from a disastrous event during launch or ascent. SpaceX also built a rocket engine test stand for developing an abort system. Engineers from NASA and SpaceX analyzed the trajectories, loads and dynamics the spacecraft would experience as it separates from a failing rocket.
"Our NASA team brought years of experience to the table and shared with SpaceX what components, systems, techniques and processes have worked for the agency's human space transportation systems in the past and why they've worked," said Jon Cowart, NASA's SpaceX partner manager during CCDev2. "This sharing of experience benefitted both NASA and the company, and is creating a more dependable system at an accelerated pace."
SpaceX is one of three U.S. companies NASA is working with during CCiCap to set the stage for a crewed orbital demonstration mission around the middle of the decade. SpaceX already is executing a contract with NASA for 12 cargo resupply missions to the International Space Station.
"The Dragon spacecraft has successfully delivered cargo to the space station twice this year, and SpaceX is well under way toward upgrading Dragon to transport astronauts as well," said SpaceX President Gwynne Shotwell.
Future development and certification initiatives eventually will lead to the availability of human spaceflight services for NASA to send its astronauts to the International Space Station, where critical research is taking place daily.

NASA EXPLORES THE EARLY UNIVERSE
FROM: NASA
NASA's Fermi Explores the Early Universe
This animation tracks several gamma rays through space and time, from their emission in the jet of a distant blazar to their arrival in Fermi's Large Area Telescope (LAT). During their journey, the number of randomly moving ultraviolet and optical photons (blue) increases as more and more stars are born in the universe. Eventually, one of the gamma rays encounters a photon of starlight and the gamma ray transforms into an electron and a positron. The remaining gamma-ray photons arrive at Fermi, interact with tungsten plates in the LAT, and produce the electrons and positrons whose paths through the detector allows astronomers to backtrack the gamma rays to their source.
