Most of the early space exploration used primitive methods and techniques and thus little was discovered during those early periods . Usually , the early civilizations involved in the space explorations relied heavily on the unaided sight of the eyes . This means that such space observations and arguments were prone errors . Observations with unaided eyes are quite unreliable and

thus they only allowed discussion , arguments and interpretation of works on the philosophical basis rather than on the scientific basis . However , these primitive techniques were profound in set up the basis for furthering the studies and investigation of new techniques in modern use today . The few tools which were available at the early era of space exploration permitted the astronomers of that time to observe a few things at the skies which later acted as reference materials for the new astronomers (Mahany , 1970

The 15th and the 16th centuries was an era in which the space exploration had attracted numerous interests . Great men like Copernicus , tycho and Johannes are some of the few who did great works in the development of space studies . Copernicus reconstructed the heliocentric theory while the noble tycho utilized the quadrant and sextant in the measurement of star locations . Based on the works of the Copernicus and the data developed by tycho , Johannes Kepler successfully developed...
