Two image frames recorded during the SPACE experiment. a) At the very beginning of the experimental run, when all the dust aggregates were free-flying. b) During a slow shaking phase of the experiment (see Fig. 2). In slow shaking phases, the preferential accumulation of aggregates in the cells’ left upper corner due to microgravity disturbances (see C.1 for details) is visible. The flight direction of the rocket (i.e. direction of gas drag) and the outward radial direction (i.e. direction of centrifugal force) are indicated.
