A reconnaissance rover configured for multiple agile and autonomous landings over a small body or moon. The reconnaissance rover comprises a detection unit, a processing unit, a control unit and a drive unit. The detection unit is configured to detect at least an environment in front of the reconnaissance rover, in the direction of a trajectory of the reconnaissance rover over a surface of the small body or moon. The detection unit is further configured to provide environmental data based on the detected environment. The processing unit is configured to update the trajectory based upon the provided environmental data. The control unit interacts with the drive unit to move the reconnaissance rover according to the updated trajectory.

In a process for discharging a test mass that is free-floating in a surrounding electrode casing on board a satellite, the electrode casing is enclosed by a vacuum tank, and has one or more first electrodes for the application of electrostatic forces and/or moments to the test mass. In addition, the electrode casing also has one or more second electrodes for modulating alternating voltages (particularly, high frequency voltages) for measuring purposes onto the test mass as well as one or more light-emitting elements, which irradiate the test mass, the electrode casing and/or the electrodes particularly with ultraviolet light for generating a photoelectric effect. Automatically and iteratively, a test mass charge of the test mass is determined. A control operation for eliminating the determined test mass charge is carried out until the test mass charge has reached a defined target value.
