%X a Photograph of the TEMPUS facility on board the parabolic flight airplane. b Photographs of the samples before and after the processing in the parabolic flight 2017 are shown. The deformation of the sample after the flight is due to the contact of the sample with the sample holder at the end of the parabola. c Temperature-time profile of processing in the electromagnetic levitator on board a parabolic flight (red). The control voltage of the rf-heater (blue) shows pulses for the excitation of surface oscillations. The level of vertical acceleration (green) shows the ~20-s time window of ¦Ìg. d Variation of the high-pass filtered ¡°apparent¡± electrical resistivity as a function of time¡ªthe exponentially decaying surface oscillations can be detected after heater turn-off and after every heater pulse. e Series of frames recorded by the high-speed camera, showing the surface oscillations of the drople
