History of Space Exploration Exploration to travel in a little-known region for discovery as defined by Webster Since the age of the Greeks Anglo-Saxons have been interested in space exploration From Copernicus to Gaileo to Newton space has been looked upon with adoring eyes Space has been regarded time after time as the final frontier That was until 1957 with the launch of the Sputnik-1 when the Soviet built satellite became the first man-made satellite successfully launched out into outer space In 1958 the United States matched the Soviets with their own satellite Explorer III After that it became a free-for-all out into the darkest regions of the final frontier The ascension into space for the United States started off with rockets satellites and probes then later moved on to shuttles and larger spacecrafts In 1946 the United States started their climb towards the heavens with the NRL V-2 The rocket gave the first observations of the Suns UV spectrum In 1949 the NRL V-2 gave the first observations of solar X-rays In 1958 the Explorer III became the USs first satellite and it also discovered Earths radiation belt On August 17th 1958 the US set its sights upon the moon with the Pioneer 0 but it exploded in its first stages of ascension It was followed later in the year by Pioneer 1 and Pioneer 3 both lunar orbiters but again failure because both separately failed to reach atmospheric escape velocity The following years Pioneer 4 and 5 were launched as space probes and are presently still in solar orbit In 1962 the Aerobee Rocket was launched and observed the first x-ray star In the 1960s NASA began the Ranger space probe program They were NASAs earliest Moon exploration program probes These spacecrafts were designed to perform a crash landing upon the Moons surface They were intended to take pictures and return scientific data up until the impact
