Experiment cells inside the rocket payload. a) Schematic of the REXUS 12 rocket with the position of the SPACE module marked by a red asterisk. b) CAD drawing of the SPACE payload including the vacuum chamber (1) and the camera (2) observing the interior of the chamber through a mirror (3). c) Schematic view of the glass experiment cells (5) installed on the shaking mechanism (6). The gears of the shaking mechanism activated by a motor induced the circular motion of the cells indicated on the figure by blue arrows. The circle indicates the limits of the vacuum chamber viewport. d) Photograph of the SPACE experiment cells inside the vacuum chamber and seen through the view port. The types of dust inserted into each cell were ~120 μm-sized monodisperse in the larger cell (I) and ~330 μm-sized poly- and monodisperse in each of the smaller cells (II and III, resp.).
