摘要：

Laboratory data and corrected estimates of cosmic ray dose are used to predict the thickness and survivability of the cosmic ray-produced, primordial comet mantle ("crust"). These results support the hypothesis that the refractory mantle produced by cosmic ray irradiation of a new comet may be able to survive a comet's entry into the inner solar system for many revolutions. Because this mantle may extend to several meters in depth, the proposed CRAF and Rosetta probes would have to be extended to reach unprocessed cometary material. © 1991.
