Paper Abstract

It has been seven years since we presented evidence for liquid water on comets and the wet comet theory that comets melt and undergo an irreversible phase change on their rst passage through the inner solar system, and since then there have been three more comet ybys and analysis on returned cometary material. We review the wet comet model and discuss the new data, showing that the model not only has been further vindicated, but explains several more independent observations. Not only do comets show evidence of some melting, they show evidence of complete melting.
