Abstract
Earth impactors (EIs) pose a significant threat. Upon EI detection, a response mission is required. The proposed architecture is suitable for responding to 75% of EIs. For rapid response, the reconnaissance and the tactical nuclear intervener craft are launched in close succession. The extended response timeframe allows collected data analysis before launching an intervener craft to slowly shift the EI's orbit. A small spacecraft equipped with a radio science package, visual camera, multi-spectral imager, LIDAR and, optionally, a radar tomography sensor will be used for reconnaissance. Sensor tasking and control will be autonomous based on controller-supplied objectives.
