Another example is problematic interaction with the spacecraft's Attitude Control System (ACS), especially for spinning satellites which can suffer resonance between slosh and nutation, or adverse changes to the rotational inertia. Because of these types of risk, in the 1960s the National Aeronautics and Space Administration (NASA) extensively studied liquid slosh in spacecraft tanks, and in the 1990s NASA undertook the Middeck 0-Gravity Dynamics Experiment on the Space Shuttle.
A further example involves issues with the spacecraft's Attitude Control System (ACS), especially concerning spinning satellites that may experience resonance between sloshing and nutation or suffer from adverse rotational inertia changes. Because of these risks, NASA studied liquid slosh in spacecraft tanks extensively during the 1960s and conducted the Middeck 0-Gravity Dynamics Experiment on the Space Shuttle in the 1990s.
