In class, we have been examining the effect of a gravitational moment on an axisymmetric rigid body (spacecraft) in a circular or eccentric orbit. As noted, we will use a circular orbit and the reference orientation discussed in class. We will also explore the use of spin to stabilize a spacecraft S when the effects of the gravity moment are undesirable. Assume an Earth satellite formed by a uniform disk D and a uniform rod R with dimensions below. Both D and R are comprised of the same material with the same uniform density. R diameter = .01m R length = L Disk thickness = .01 m Disk radius = 1.00 m Both cm of R and D are collocated at the center of the disk
