The formation of planetesimals from preplanetary dust involves a variety of physical processes, such as dust transport, dust collisions, adhesion, or aerodynamics of non-spherical dust grains. Recent progress in theoretical and experimental work has brought us closer to a detailed understanding of the various stages that lead from micrometer-sized dust to kilometer-sized planetesimals. Based on the latest results from the laboratory and from modeling, an overview of the "hard facts" of preplanetary dust aggregation will be given. An outlook on future experimental research from the laboratory to the International Space Station ISS will also be presented. |
