A Call to (Considered) Action

Abstract: The purpose of this paper is to call upon the Congress of the United States to initiate, via the National Research Council or other appropriate body, a formal analysis of the circumstances presented by the close encounter between the Earth and asteroid 2004MN4 in April 2029, and the potential for a subsequent collision with Earth in 2036. Informal analysis indicates that the accuracy of our knowledge of the asteroid's trajectory using optical and radar tracking is likely to be inadequate to make a timely deflection decision in the improbable event that one should be needed. Should this claim prove to be correct after formal analysis serious consideration should be given to placing a radio transponder on 2004MN4, perhaps as one of several scientific objectives. This mission should be launched in the near future in order to provide adequately accurate trajectory information about the asteroid by 2014, the approximate date by which a deflection mission decision, if required, would have to be made.
