2 In Measurement of Interplanetary Dust 2.3 Particle Collection Experiments and Their Interpretation
Part of the Lecture Notes in Physics book series (LNP, volume 48)


Cosmic dust fragmentation in near-earth space is strongly suggested by the high fluxes (≈102/m2s) of submicron particles observed in the upper atmospheric collection experiments, the lower fluxes (≈10-1/m2s) observed in near-earth space by the lower ensitivity detection experiments and the much lower fluxes ( ≈10−4/m2s) observed in the deepspace experiments. Various possible fragmentation mechanisms are discussed.
