NASA NEO Deflection Application: Current Capabilities and Limitations

  • Nahum Melamed
Part of the Space and Society book series (SPSO)


The NEO deflection simulator demonstrates what capability is needed for deflection of fictitious but realistic hazardous Near-Earth Objects (NEOs) by high-energy kinetic impactors. Focus is placed on requirements for launch systems, payloads, guidance, software, resources and long-term sustainability. Mission timeline is addressed in terms of what we can do in a month, six months, or a few years, and gaps in our ability to respond are identified. Finally, the chapter proposes how to close the gaps and quantify the resulting technical and monetary benefits.
