| 内容記述 | The present investigation is concerned with research related to the design of a method for capturing effectively particulate matter and volatiles from the tail of a comet for the purpose of chemical analysis. It is envisaged to conduct a space mission with a means of propulsion which would make it possible to maneuver the space probe into the coma of the comet. The collecting medium has to be chemically inert and easily distinguishable from the particles being collected. It is proposed to employ a film of solid xenon at a temperature of 65 K as the collecting medium. Sublimation of this film and the resultant pressure will be used to concentrate the particles on a small area suitable for analysis. Attention is given to the laboratory apparatus, the experimental work, the experimental results, and the cryogenic requirements for a space mission. |
