The mass of the rest of the internal structures andcommunication electronics are negligibly small. Calculate the rotationalinertia of the space telescope about its symmetric Z axis.Suppose the telcacope is launched from the cargo bay of the space shuttle. Thespace shuttle first adjust it orientation so that the axis of the telescope ispointing at a distant star so that it can collect signal from the star. Thetelescope is set into a spinning motion by two jets installed symmetrically onthe circumference of the telescope (See figure 4b) before it is released. Thetorque generated by each jet is graphed in figure 4c. Both jets are firedsimultaneously. What is the purpose of setting the space telescope intorotational motion?
