Mass spectrometric analysis in planetary science: Investigation of the surface and the atmosphere

Knowing the chemical, elemental, and isotopic composition of planetary objects allows the study of their origin and evolution within the context of our Solar System. Landed probes are critical to such an investigation. Instruments on a landed platform can answer a different set of scientific questions than can instruments in orbit or on Earth. Composition studies for elemental, isotopic, and chemical analysis are best performed with dedicated mass spectrometer systems. Mass spectrometers have been part of the early lunar missions, and have been successfully employed to investigate the atmospheres of Mars, Venus, Jupiter, Saturn, Titan, and in comet missions. Improved mass spectrometer systems are foreseen for many planetary missions currently in planning or implementation.  相似文献

Determination of the surface-averaged composition of the regolith of phobos by measurements of the secondary ion flux during the <Emphasis Type="Italic">Phobos-Grunt</Emphasis> mission in the MANAGA-F experiment     

G. G. Managadze  R. Z. Sagdeev  A. E. Chumikov  V. T. Cherepin  G. Z. Saralidze 《Solar System Research》2010,44(5):385-392

The onboard time-of-flight mass reflectron MANAGA-F is described which is aimed at measuring the elemental and isotopic composition of the secondary ion fluxes generated under the influence of solar wind. It is shown that by using this apparatus, the composition of the surface regolith layer averaged over a considerable area can be determined while approaching Phobos. After the landing of the spacecraft on the surface of Phobos, the measurements will be aimed at examining the local characteristics of the regolith and a new mechanism for water synthesis in the process of ion collisions. The apparatus allows for the mass of the secondary molecular ions to be detected and determined, including organic ones which arise during the bombardment of the regolith by ions of different origins. The main scientific problems to be solved using the given apparatus are considered in the paper. The working principle of the apparatus together with its analytical and technical characteristics and design particularities are presented. Information concerning the range of its applications for solving a number of challenging tasks of contemporary science is given. The MANAGA-F apparatus is shown to be the first realization of an original new-generation onboard device that has been invented, developed, and produced at the Space Research Institute of the Russian Academy of Sciences (SRI RAS).  相似文献
