    Rotating, tumbling: two words for basically the same thing: movement around an 
    With a rotation I think of a spin around a stable pointing axis (indicating 
    attitude control): with tumbling of a spinning motion with the direction of the 
    spin axis (attitude) not controlled.
    With Nanosail, the latter is more likely imho. So I think tumbling is the 
    correct word.
