Telescopes, Probes, Spacecraft, and the Future of Space Exploration [PDF ebook] 

Space exploration depends on a comprehensive understanding of the forces at work in the universe, and so for centuries, it seemed impossible that humans could leave Earth to travel in space. Telescopes, Probes, Spacecraft, and the Future of Space Exploration meets Next Generation Science Standards and describes how foundational understanding of astronomy developed and how visionaries invented the technology to make space travel a reality. The book also considers achievements on the horizon that could change our understanding of astronomy and our way of life.
