A generalized mathematical model is investigated of sloshing dynamics for Dewar containers, partially filled with a liquid of cryogenic superfluid helium II, driven by both gravity gradient and jitter accelerations applicable to two types of scientific spacecrafts, which are eligible to carry out spinning motion and/or slew motion to perform scientific observations during normal spacecraft operation. Two examples are given for the gravity probe-\(B\) with spinning motion, and the advanced \(X\)-ray astrophysics facility-spectroscopy with slew motion, which are responsible for the sloshing dynamics.
