History of Space Research:
Early Theories and Astronomical Discoveries
Before rockets and satellites, space research was purely observational. Ancient civilizations such as the Babylonians, Greeks, and Egyptians studied the stars, tracking celestial movements and developing early astronomical theories. These early astronomers laid the foundation for our understanding of the universe, using rudimentary tools and keen observations to chart the night sky.
Aristotle and Ptolemy, Greek philosophers, believed in a geocentric universe where Earth was at the center. Their theories dominated scientific thought for centuries, shaping the way people viewed the cosmos. However, it was the work of Copernicus and Galileo that revolutionized space research. Copernicus proposed the heliocentric model, suggesting that the Earth orbits the Sun, a theory that Galileo later supported with his detailed observations using the telescope. Galileo’s telescope allowed the first detailed observations of planets and moons, providing evidence that contradicted the geocentric model.
