I’ve been doing some really fun work using cesium to display trajectories generated by GMAT at different planets.

I can easily replace the Earth with a Mars sized ellipsoid using a topography map of mars [Here]( [Hello World - Cesium Sandcastle](https://sandcastle.cesium.com/#c=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))

However, this globe still rotates at 1 revolution per day with respect to the inertial frame. Any advice on how to change the rotation rate of a globe with respect to an inertial frame?
