Short summary
The High Accuracy Accelerometer calibrated data collected during the JUICE (JUpiter ICy moons Explorer) Lunar Earth Gravity assist flyby was compared with predicted non-gravitational signals derived from analytical models, showing good agreement. Moon gravity gradient and thermoelastic displacement of solar array during the penumbra phases have been detected. High Accurate Accelerometer detected also unexpected signals such as instrument interference and outgassing event.
