  1. David Gump, CEO Asteroid InitiativeIdea Synthesis Workshop Sept. 30, 2013

  2. Keck Method: Multiple Risks For any given magnitude, NEO mass could vary by 200:1 Even radar establishes only the volume, not the mass Scouting missions can retire most ofthe mass uncertainty

  3. Bigger NEAs are Easier Easier to detect now, and in old imagery Easier to get sufficient photons for light curves and spectrographic analysis Easier for spacecraft to find during closing maneuvers: brighter & better defined orbits Easier to land on – larger NEAs spin slower

  4. NEAs 100m+ are the Threat Are they rubble pilesor monoliths? Are they rubble pilesor monoliths?

  5. Decision Principles Design the program before designing a specific mission Demo a method that’s generally useful, not limited to rare situations

  6. NEW NEO Initiative Lowest Possible Cost to all Highest Possible Return For All Modeled upon COTS Commercial Orbital Transportation Services ILDD Innovative Lunar Demonstrations Data Fixed Price and below-cost to insure private investment Milestones NASA buys what it needs, and industryfunds additional capabilities to serve commercial markets Resulting systems sustained by commercial demand

  7. Approach: Gather boulders and regolith up to an ARV’s capacity ARV size is independent of asteroid size Smaller ARVs reduce early mission costs Collection process can be selective Sand (easy to process) Specific boulders (varied colors)

  8. Scouting Missions Low-cost precursor missions can deliver samples soon to “beyond Moon” location • Collective sample mass easily can fill Orion’s 100 kg limit Samples from multiple NEAs provide richer data thana single Keck rock would

  9. Scout

  10. You Have Your Plans

  11. We Have Our Plans

  12. Path to Mutual Success Commission several precursors for rendezvous and sample return missions Issue BAA for ARM Ideas Based on Gathering Material from Any Size NEAand Industry-Based Missions With ARV size unhitched from NEA size, seek for least cost combinations (Launch vehicle, solar array, propulsion unit, etc.)
