Since the early development of the cosmic dust research that started almost a century ago, a wide variety of the sample collection techniques has been developed. Such direct sampling of cosmic dust (or micrometeoroids, micrometeorites, interplanetary dust particles (IDP)) has enabled subsequent analyses of these extra-terrestrial micro particles at ground laboratories in great detail. In coming years, Japan will have an array of new opportunities of cosmic dust collection from space, stratosphere and Antarctica. However each collection site causes certain biases of samples in terms of physical and chemical alterations, selection effects and contamination. Here we review the cosmic dust collection from deep sea sediments, Greenland blue lakes, Antarctic ice cores, stratosphere and both near-Earth and interplanetary space, together with a brief description of the curation system of the samples being operated by NASA/JSC.
