Was this correctly printed ?? The IUS spun itself and the payload up to 174 RPM prior to separation ?? That seems like an incredible controls problem to prevent the stack from spinning in a very wide "cone". Also at actual separation, the CG will jump back some 30-40 feet maybe (don't know actual Galileo dimensions) - again sounds like one hell of a controls problem. Was this meant to be 2.9 RPMinutes ??
