... As the National Research Council's (NRC's) Committee to Review Near-Earth Object Surveys and Hazard Mitigation Strategies noted in its August 2009 interim report (NRC, 2009)

... However, unlike ground-based telescopes, space options carry a modest launch risk and a more limited lifetime: ground-based telescopes have far longer useful lifetimes and could be employed for con tinued NEO surveys and for new science projects. (Ground-based telescopes generally have an annual operating cost that is approximately 10 percent of their design and construction costs.)

... In addition to spacecraft reconnaissance missions as needed, the committee concluded that vigorous, groundbased characterization at modest cost is important for the NEO task. Modest funding could support optical obser vations of already-known and newly discovered asteroids and comets to obtain some types of information on this broad range of objects, such as their reflectivity as a function of color, to help infer their surface properties and mineralogy, and their rotation properties.

... Goldstone is one of the three deep-space communications facilities of the Deep Space Network, and its overall funding includes additional equipment for space communications. MITIGATION "Mitigation" refers to all means of defending Earth and its inhabitants from the effects of an impending impact by an NEO.

... This research program does not include mitigation space experiments or tests that are treated elsewhere in this report. NATIONAL AND INTERNATIONAL COOPERATION Responding effectively to hazards posed by NEOs requires the joint efforts of diverse institutions and indi viduals, with organization playing a key role.

... In addition, the committee was impressed with the European Space Agency's early development of the Don Quijote spacecraft mission, which would consist of an observing spacecraft and a kinetic impactor. This mission, though not funded, would have value for testing a mitigation technique and could still be an opportunity for international cooperation in this area.
