Historical Perspectives,pments from the early zodiacal light observations to the late spaceprobe experiments, which directly explore the properties of the solar system dust grains. Secondly and not to forget the human side, we look at the personal aspects of the dust researchers, their organization on the scientific intern

Optical and Thermal Properties of Interplanetary Dust, extremely low optical thickness, is indeed visible through the faint and evanescent glow of the zodiacal light. Two types of physical processes playa role in the emission of light by the interplanetary dust cloud: the scattering of solar light by dust particles, prevailing in the visible domain, an

Discoveries from Observations and Modeling of the 1998/99 Leonids,are encounter with fresh comet ejecta that can be precisely dated to the 1899 return of the parent comet. Earth’s atmosphere acted as a giant detector for measuring composition and morphology of large mm-cm sized grains during what was in effect a comet mission to 55P /Tempel-Tuttle. The high meteor

In Situ Measurements of Cosmic Dust,in interplanetary space. Pioneers 8 through 11, Helios, Galileo and Ulysses spaceprobes measured interplanetary dust from 0.3 to 18 AU distance from the Sun. The Earth satellites HEOS, Hiten, as well as other spacecraft, determined the flux of micrometeoroids at 1 AU. The size distribution from a fe

Instrumentation,hapter reviews the methods of detection and discusses their strengths and limitations. Detailed descriptions are given for those detectors which have significantly advanced the state of the art of interplanetary dust research. Also reviewed are laboratory facilities required for the calibration of t
