Probing the presently tenuous link between comets and the origin of life.

A unique set of millimeter-wave experiments for future cometary space missions is discussed. These experiments could yield answers to many basic questions about the presently undetermined nature of cometary nuclei and inner comae. This same set of experiments, designed to do fundamental cometary research, could simultaneously provide information on whether the accepted biological requirements necessary for the development of life are met in comets.
