This drone hauled a model of the Juventas CubeSat high into the air, as a practical test of the antennas designed to perform the first radar soundings of the interior of an asteroid. For the most accurate measurements of the antennas radiation properties, they had to be as far away as possible from other objects, so the Juventas model was hung 10 m down from the drone, which was flown up to 50 m into the sky by the Hexapilots drone company. The test was performed by TU Dresden.
