Nope, not quite. If the fuel had simply dribbled out from the outer
edges of the spacecraft, the spin would have slowed down as the
propellant moved outward.

>How much was the mass of the propellant?

The figures I have show 63.37 kg of N2O4 in each of two tanks, 34.35 kg
of MMH in each of two tanks, plus 26.65 kg of NH3 in each of two tanks.
I can't find a figure for the helium mass.
