One of the main primary conclusions of the Deep Impact mission is that Comet Tempel 1 is composed primarily as dust, at least down to tens of meters.<br /><br />Suppose we needed to deflect a different comet, one which appears to be identical to Tempel 1, to prevent a terrestrial encounter.<br /><br />Given Deep Impacts's conclusion, what is the optimal deflection method?<br /><br />What would be the effectiveness of nuking the comet?<br /><br />Can the dust be used as fuel in a mass-driver thruster? What would that look like?
