In 2003 NASA commissioned a Science Definition Team (SDT) (Stokes, et al., 2003) to study the threats posed by Near-Earth Objects (NEOs), recommend efficient methods for detecting NEOs down to 140 meters in diameter, and suggest conceptual mitigation techniques. In this same time frame, Congress set the goal of cataloguing 90% of all NEOs down to 140 meters diameter by 2020. The SDT concluded that the infrared passband from ~5 to ~11 microns is the best for finding NEOs; that an aperture of 50doi:10.1063/1.3326270 fatcat:3nywnloez5ayloa6ydn2hqwbsm
