The cover page shows absorption images of four Bose‐Einstein condensates generated consecutively during the nine seconds of free fall in a single launch of the catapult located at the bottom of the Bremen Drop Tower. The condensates were observed at different times (25, 50, 75 and 100 ms), illustrating the expansion of the wave‐packet. This experiment was performed using in a miniaturized ultra‐cold atom trap by the QUANTUS collaboration supported by the German Space Agency DLR. The graphics was designed by Jan Rudolph and Holger Ahlers from the group of Prof. Ernst Maria Rasel (Leibniz Universität Hannover).
