Space Based Astronomy (PDF 103P)
This guide help students and teachers understand the significance of space-based astronomy, astronomical observations made from outer space. The guide contains few of the traditional activities found in many astronomy guides such as constellation studies, lunar phases, and planetary orbits. It tells, rather, the story of why it is important to observe celestial objects from outer space and how to study the entire electromagnetic spectrum.
