ISS Servicing for NASA ISS Servicing for NASA Presentation Transcript

  • ISS Servicing for NASA Lawrence Williams March 10, 2010 © SpaceX
  • SpaceX Overview
    • Founded in mid-2002 with the singular goal of providing highly reliable, low cost space transportation for both cargo and crew
    • Over 800 employees and growing
    • 550,000 sq ft (51,000 sq m) of offices, manufacturing and production in Hawthorne, California
    • 300 acre (121 hectares) state-of-the-art Propulsion and Structural Test Facility in central Texas
    • Launch sites at Kwajalein and Cape Canaveral
    • Developing launch site at Vandenberg

  • 2009—The Year in Review DragonEye LIDAR system during its recent flight aboard Space Shuttle Endeavour Liftoff of the Falcon 1 RazakSAT Successful Qualification of Falcon 9 Stage 1 and 2 Building Our Future on Demonstrated Success
  • Falcon 9 Capabilities
    • Inaugural flight from Cape Canaveral in early 2010
    • Lowest mission price in this vehicle class
      • Greater than a factor of 5 cost reduction compared to our domestic competitors
    • Two-stage EELV-class launch vehicle
      • Designed to meet NASA man-rated safety margins and failure tolerances
      • Engine-out reliability
    • 1st Stage powered by 9 Merlin engines
      • Over 4.9 MN (1.1 million lbf) thrust in vacuum
    • 2nd Stage powered by Merlin Vacuum engine
      • 42.7 kN (96,000 lbf) thrust in vacuum
    • Diameter 3.6 m (12 ft); Length 55 m (180 ft)
    • Payload capability (Block 2)
      • 5.2 m (17 ft) fairing
      • 10,500 kg to LEO

  • Dragon Spacecraft Nosecone Jettisoned after stage separation. Capsule – fully recoverable Contains pressurized cargo, experiments or crew, hatches, thrusters & propellant, parachutes and heat shield. Trunk – not recoverable Contains unpressurized cargo and small deployable satellites. Supports solar panels, thermal radiator. Jettisoned before reentry. Passive Common Berthing Mechanism (PCBM) Pressurized Section Heat Shield Trunk (Unpressurized) Service Section (Unpressurized) Total Payload Capacity: 6,000 kg to LEO Capsule Down-mass Capability: 2500 kg
  • Dragon Spacecraft Applications
    • Commercial Orbital Transportation Services
    • SpaceX receives $278M over 3.5 years
    • Demonstrates cargo services to and from the ISS
    • Commercial Resupply Services
    • SpaceX awarded $1.6B for 12 cargo missions, 2010 – 2015
    • Minimum of 20,000 kg delivered
    • Option for additional missions
    • Free-flying recoverable platform for microgravity research & technology demo
    • Regular, frequent, commercial access to space
    • First mission in early 2011
    NASA’s “COTS” Program NASA’s “CRS” Program SpaceX’s “DragonLab” Program
  • Future Manned Capability
  • Government Investment in Innovation
    • Initial government investment coupled with private funds have created entire new industries:
      • Internet -> E-commerce (i.e. Amazon, Google)
      • Aviation -> Passenger airlines (i.e. Southwest), delivery services (i.e. FedEx)
      • Satellites -> Entertainment (i.e. Direct TV), GPS Systems (i.e. Garmin)
    • Initial government investment in commercial human space transportation will similarly create/revolutionize new industries:
      • Medical
      • Materials
      • Tourism
      • Energy
