This short course aims to introduce space science and satellites for those who will supervise, manage, or achieve by themselves any practical work or projects based on satellite images, remote sensing, or geographic information systems. The course explains a group of overview topics in a gradual sequence that matches the lifetime of a satellite from its start to its end. The topics are as follows: First, an introduction to satellites, why they were invented, how they fly in their orbits (from the Orbital Mechanics point of view), what their missions are, and their classification. Second, orbit design and its effect on the quality of satellite images through explaining orbit types, the relation between satellite orbits and its missions, the effect of an inaccurate orbit design, and how to design an orbit. Third, satellite system components - Ground Segment, Space Segment, and Launcher- satellite components and subsystems, how satellites are launched, and who can perform launching. Finally, the course explains topics related to satellite lifetime, such as when the lifetime ends, what perturbations are and their effect on life time, and how we get rid of satellites after their lifetime ends.
