Nevertheless, it is known from experience that such disasters will occur, and moreover experts can assess the likely damage. The United States and other countries around the world have responded to the risk of earthquakes by committing to various civil-defense and mitigation programs, including research programs.

If, however, there are available active mitigation options, like changing the orbit of an impactor, again better information is needed: One must be able to predict with confidence the response of an impactor to specific forms of applied forces, impacts of various types and speeds, or various types of radiant energy, such as x rays. The required information goes beyond the basic physical characterization that determines the size and mass of the impactor and includes surface and subsurface compositions, internal structures, and the nature of their reactions to various inputs.

for studying people's perception of impact risks, including their mental models, and for increasing the understanding of their possible misconceptions and/or lack of knowledge, needed to develop appropriate plans and simulation exercises in preparation for a pos sible impact event.
