Congress has mandated that NASA detect and track 90 percent of NEOs that are 1 kilometer in diameter or larger. These objects represent a great potential hazard to life on Earth and could cause global destruction. NASA is close to accomplishing this goal. Congress has more recently mandated that by 2020 NASA should detect and track 90 percent of NEOs that are 140 meters in diameter or larger, a category of objects that is generally recognized to represent a very significant threat to life on Earth if they strike in or near urban areas. Achieving this goal may require the building of one or more additional observatories, possibly including a space-based observatory. Congress directed NASA to ask the National Research Council to review NASA's near-Earth object programs. This interim report addresses some of the issues associated with the survey and detection of NEOs. The final report will contain findings and recommendations for survey and detection, characterization, and mitigation of near-Earth objects based on an integrated assessment of the problem.Near-Earth objectsAsteroidsHazard mitigationNear-Earth objects.Asteroids.Hazard mitigation.523.5National Research Council (U.S.).Committee to Review Near-Earth Object Surveys and Hazard Mitigation Strategies.National Research Council (U.S.).Space Studies Board.National Research Council (U.S.).Aeronautics and Space Engineering Board.National Research Council (U.S.).Division on Engineering and Physical Sciences.United States.National Aeronautics and Space Administration.MiAaPQMiAaPQMiAaPQBOOK9910963965803321Near-earth object surveys and hazard mitigation strategies4474165UNINA
