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 کاملGalileo in-situ dust measurements in Jupiter’s gossamer rings
Galileo was the first artificial satellite to orbit Jupiter. During its late orbital mission the spacecraft made two passages through the giant planet’s gossamer ring system. The impact-ionization dust detector on board successfully recorded dust impacts during both ring passages and provided the first in-situ measurements from a dusty planetary ring. During the first passage – on 5 November 20...
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 کاملExplosion 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 ...
