This is one of the more fascinating space stories. The modeling for such an object should be (relatively speaking), rather simple. Something isn’t going to speed up or slow down without a force being applied to it. So NASA should be able to model this quite accurately.
Oh god. Please aim higher than that. Not saying that Blender ain’t powerful, because it clearly is, but it’s UI is just plain shit. (Unless there have been some massive improvements over the last few years.)
