Abstract: This project is related to the inventor, Cyrus Nejat, previous patent Application Number: U.S. Ser. No. 12/011,127. In this study, the main discussion emphasizes on building a spacecraft based on mathematics. The orientation of the low thrust engine spacecraft was structured in such a way that the Kinematics and kinetics equations be written for large elements, by means of the purposed Nejat Kinetics Expansions and Nejat Kinematics Expansions. These equations were used to design Nejat Space Station. Simplified CN (Cyrus Nejat) Equations of Motion used for the Special Spacecraft Rout in Space.
