In Situ Measurements of Interstellar Dust
We present the mass distribution of interstellar grains measured in situ by the Galileo and Ulysses spaceprobes as cumulative flux. The derived in situ mass distribution per logarithmic size interval is compared to the distribution determined by fitting extinction measurements. Large grains measured in situ contribute significantly to the overall mass of dust in the local interstellar cloud. Th...
متن کاملDevelopment of a Dust Particle Analyzer for In- situ and Simultaneous Measurements of Size and Charge Distributions of Martian Dust
In this report we present our progress of the NRA 02-OSS-01 project on the development of a prototype Dust Particle Analyzer (DPA) and its performance under simulated Martian atmospheric conditions. Both theoretical analysis assuming the predicted environmental conditions of Mars and experimental data on the development of the DPA show that the instrument has an excellent potential for its appl...
متن کاملrole of cultural iran in promotion of multilaieralism in central asia and caucasus
cultural iran is a scope that is more extended than the political territories of iran as a political unit. this concept means that cultural geography(mehdi moghanlo-1383-1) of iran is greater than its political geography which, according to history, has a long history extending west-east from kandahar to the euphrates and north-south from the persian gulf to the caucasus including transoxiana a...
15 صفحه اولExplosion dust particle size measurements.
In situ measurements of the sizes and concentrations of dust particles generated by the detonation of high explosives in clay soil near Leesville, La., sandy clay soil near Huntsville, Ala., and sandy soils near Orogrande, N.M. are reported. Measurements were generally made within 1 m of the surface (in one case 10 m) at distances ranging from 10 to approximately 50 m from the detonation point ...
متن کاملIn Situ Sampling of Relative Dust Devil Particle Loads and Their Vertical Grain Size Distributions.
During a field campaign in the Sahara Desert in southern Morocco, spring 2012, we sampled the vertical grain size distribution of two active dust devils that exhibited different dimensions and intensities. With these in situ samples of grains in the vortices, it was possible to derive detailed vertical grain size distributions and measurements of the lifted relative particle load. Measurements ...
