  1. United Launch Alliance Commercial Crew Overview George Sowers 13 February 2013

  2. ULA Launch History (Through 2012) Sixty-Six Launches, 100% Mission Success

  3. TDRSS-K Jan 30, 2013 LDCM Feb 11, 2013 36 Atlas V Launches, 107th Consecutive Atlas Success

  4. Commercial Crew • Commercial Crew Integrated Capability (CCiCap) Development and Launch of the Boeing CST-100 and Sierra Nevada Dream Chaser on Atlas V-4X2 • POP through May 2014 • ULA Effort Includes • Human Spaceflight Certification • Emergency Detection System • Dual Engine Centaur • Common Avionics • LC-41 Modifications • Crew Access Tower & Arm • Elevator & Stairway • Slide Wires • Initial Launch Capability • Uncrewed Mission in August 2016 • Crewed Mission in December 2016

  5. Human Spaceflight Certification CCiCap Base Phase includes Integrated HSF Certification Effort Atlas V compliance with NASA CTS-1100 and spacecraft requirements Integrate Crew Safety baseline Integrate Loss of Crew/Mission PRA Integrate Hazard Analyses Leverage NASA Atlas V Certification Atlas V certified to NASA Risk Category 3 (highest certification level) Atlas V nuclear safety launch approval Human Spaceflight Certification is a combination of technical/operations requirements satisfaction, flight history MRO/Atlas 401 Aug 2005 Pluto/Atlas 551 Jan 2006 Mars Science Lab Nov 2011 NASA can leverage the body of evidence already available for Atlas V HSF Certification

  6. Emergency Detection System (EDS) • Critical element for system level human rating • Prototype developed during CCDev1 • Design matured in CCDev2 • Design to be completed under CCiCAP • Fault tolerant computer • Existing redundant instrumentation • Measurements list chosen to provide complete fault coverage, but minimize false aborts Monitor Launch Vehicle Detect Safety Critical Anomalies Safe the Launch Vehicle Initiate the Abort Command

  7. LC-41 Launch Site Accommodations Crew Access Tower (CAT) Generic SV Rotating Crew Access Arm (CAA) Slide Wire System Launch Exhaust Duct (LED) N Pad Equipment Building (PEB) Autocoupler Building (ACB)

  8. Summary • Atlas’s unparalleled record of mission success provides foundation for crewed missions • NASA Cat 3 and nuclear certification • On track to develop human spaceflight unique accommodations for 2016 ILC • Human Spaceflight Certification • Emergency Detection System • Launch Site Accommodations
