Comet Nucleus Sample Return Missionave been accomplished in NASA and ESA, the objective of which was to conduct an assessment of candidate mission concepts and to define key design, operations and technology requirements. These studies have by now provided a technical baseline to sufficient extent to generate performance, schedule pl

Furthermore, the lack of detailed analytical methods such as spectrometry or chromatography did not allow a detection of chemical changes induced by irradiation. Anyhow, destruction of ice samples by micro-explosions or larger outburst

The purpose of this paper is to review some work made in our laboratory in the last 5 years (with a quotation to the results obtained in other laboratories), by describing irradiated materials, used techniques and astrophysical application

The Structure and Dynamics of Amorphous Water Ice and Trapping of Gases in Itstream of water vapor, from a reservoir of throughly degassed triple-distilled water, was directed at the plate, through a capillary tubing with a diffuser on its tip. An ice layer, consisting of 10. – 10. water molecules was deposited on the plate during ∼ 45 min. A stream of gas (Ar, CO, N., CH.,

Initial Comet Simulation Experiments at DFVLRoduced new impulses to simulation and modelling of the nucleus and its behaviour in the solar radiation field. Since 1969 several attempts of laboratory simulation had been made, first by Russian groups in Leningrad and Dushanbe (Kajmakov and Sharkov, 1972; Dobrovolsky and Kajmakov, 1977; Dobrovolsk

An earlier, similar report (Donn, 1985) included material covered at this meeting in sessions on ices and on carbon type matter. The attempt was to include all relevant processes for silicates not contained in the reviews of optical phenomena and grain irradiation. Many of the phenomena disc

In addition, metallic components are important because they carry the charge inside dense clouds regulating the ion-molecule chemistry in these regions. Despite these facts and active research which is presently lasting since over 50 years,
