Synoptic observations of near surface processes of an insolated ice-dust body under space conditions: The case of KOSI 9 and 10The recent experiments of the Comet Simulation Project, KOSI 9 and KOSI 10, for the first time yielded synoptic results of physically correlated phenomena near the surface of insolated porous ice dust mixtures (90% H2O, 10% olivine, 0.1% fine dispersed carbon, sample mean density 0.40 +/- 0.001 g/cm(sup 3)) under space conditions. Correlations were observed e.g. between (1) grain size of emitted dust and dust mantle formation; (2) surface avalanches and local surface temperature; and (3) lateral variations of the surface temperature and the thickness of the dust mantle at the end of the experiment. The dynamic surface processes and the observed structural parameters of the dust mantle and the emitted mineral residues are discussed in view of real comets.
