Space—the seemingly boundless vessel holding billions upon billions of swirling galaxies—is today's final frontier. Astronomers continue to be the pioneers who venture into this vast environment, creating the charts that will guide those of us ready to join the adventure. Students study the Earth as a celestial object before progressing to lunar science and lunar exploration, and then on to the Solar System. Activities explore the origin of the Moon, celestial motions, Moon phases, lunar geology, cratering processes, imaging technologies, scaling, and space exploration.
