Space exploration has often been used as a proxy competition for geopolitical rivalries. The early era of space exploration was driven by a "space race" among might countries. Nowadays, many advanced nations have entered the space arena and competed with one another for the space technology development as they recognize the importance of space technologies for national strength. In general, physical exploration of space is conducted both by human spaceflights and by robotic spacecrafts. To promote the scientific standard of space vehicle performance, stability, and control, it requires analysis of the six degrees of freedom of the vehicle's flight. One is the translational motion in three dimensional axes; the other is the orientation about the vehicle's center of mass in these axes, known as pitch, roll and yaw. In this paper, the main goal is to propose an adaptive fuzzy sliding-mode controller for spacecrafts with thrusters to follow the predetermined trajectory in outer space by use of employing the spacecraft attitude control. By using fuzzy inference mechanism, the upper bounds of the lumped uncertainty can be estimated, and the adaptive theory with center adaption of membership functions is designed to estimate optimal upper bounds of the lumped uncertainty, respectively. For the above reasons, we know that the attitude control of spacecrafts for the space exploration is essential to successfully develop the space activities [1].
