An efficient simulation has been successfully developed to analyze the dynamics and control of spacecraft comprised of multiple rigid/flexible articulating bodies. The implementation employs a typical order-(N) multi-body dynamic approach coupled with a state-of-the-art symbolic equation optimization algorithm. The simulation has been modified to compute the instantaneous acceleration at any arbitrary location on an orbiting body. Gravity gradient, rotational and aerodynamic accelerations contribute to the total quasi-steady state microgravity environment. The simulation is used to evaluate the microgravity levels within Space Station Freedom to demonstrate the excellent microgravity environment which it can provide for scientific experiments.
