For thousands of years, the night sky has inspired wonder. As technologies have advanced, so too has our ability to investigate our solar system and beyond. First with the naked eye, then with telescopes, satellites, landers, probes, manned spacecraft and ultimately space rovers, humans have observed and studied both our galaxy and others. Learn about space and the people who illuminate its wonders in this multimedia learning resource collection featuring National Geographic Explorers Cynthia Chiang, Munazza Alam, Sophie Dia Pegrum, and more.
