[en] Possible space experiments for observing the geometric, spectroscopic, and photometric behavior of comets are described. These experiments are proposed beacause an interpretation of cometary data may yield essential data on the formation and evolution of the solar system and the nature of interplanetary space. The various ways of obtaining significant planetary data are examined. These include the use of: (1) far ultraviolet observations by orbiting astronomical observatories; (2) artificial gaseous comets formed by high-altitude release of gases such as NH[SUB]3[/SUB]; (3) orbiting artificial cometary nuclei such as blocks of CO[SUB]2[/SUB] or NH[SUB]3[/SUB] ice, perhaps with an addition of meteoric material; and (4) fly-by p probes of a comet such as Encke's periodic comet. The significance of the data that would be obtained by each of these methods is predicted.
