High Precision Astrometry in Asteroid Mitigation - the NEOShield Perspective

Status Report From: arXiv.org e-Print archive
Posted: Sunday, November 24, 2013

Among the currently known Near Earth Objects (NEOs), roughly 1400 are classified as being potentially hazardous asteroids. The recent Chelyabinsk event has shown that these objects can pose a real threat to mankind. We illustrate that high precision asteroid astrometry plays a vital role in determining potential impact risks, selecting targets for deflection demonstration missions and evaluating mitigation mission success. After a brief introduction to the NEOShield project, an international effort initiated by the European Commission to investigate aspects of NEO mitigation in a comprehensive fashion, we discuss current astrometric performances, requirements and possible issues with NEO risk assessment and deflection demonstration missions.
