“…Therefore, its spin evolution will be more complicated than the two idealized libration modes used here as a conceptual example. Namely, the excited planar libration modes, for particular shapes of the secondary, can induce significant out-of-plane rotation (Kane, 1965;Eapen et al, 2021). Moreover, energy transitions can happen between the planar and out-of-plane rotational degrees of freedom that is attributed to resonant phenomena (Breakwell and Pringle, 1965).…”

High-fidelity numerical codes are essential for modeling the long-term spin evolution • DART may excite Dimorphos' spin, leading to attitude instability and chaotic tumbling• Dimorphos is especially prone to unstable rotation about its long axis • A chaotic spin state will affect the system's BYORP and tidal evolution • ESA's Hera mission may be able to place constraints on the system's tidal parameters
