Currently, several basic concepts for NEO (near-Earth object) hazard mitigation are under discussion. One promising deflection system is the solar concentrator concept, which focuses solar radiation onto the surface of a NEO to evaporate surface material and thus to generate a continuous thrust. If the orbit of the NEO is well known in advance (lead-time of several years) then the operation of a solar concentrator system (100 m to 1 km diameter) for the duration of several months could deflect NEOs of even 1 km in diameter from a collision course with Earth. Although construction and operation would be complex, such a system could be developed using current technology. An overview of this system, a brief conceptual analysis and an example for orbit alteration are presented and discussed.
