In our history, many great things have happened. We've been inventing and exploring things since day one. Many of these things that we have discovered or invented, we thought would never be possible in the lifetime of the Earth. But they exist now, today, they are used by almost all human beings and there are many other incredible and unmanageable things that will help us in everyday life. One of the most interesting things for me would be exploration and invention. You are about to venture into the history of space and learn how man and his objects got there. Space exploration dates back over 40 years, January 31, 1958 to be exact. On this date, Explorer 1, which was the first American satellite to be launched into space and its unknown, went into orbit around the Earth. It took off from Cape Canaveral using a modified Jupiter-C rocket called ABMA-JPL. He performed a scientific experiment by James A. Van Allen and discovered the Earth's radiation belt. Defeat and triumph are also accompanied by disappointment and failure. On March 5, 1958, Explorer 2 was launched by another Jupiter-Crocket and failed to reach orbit. On October 1, 1958, NASA was founded, taking over the existing National Advisory Committee on Aeronautics and only ten days later, the United States. - The IGY space probe was launched to an incredible height of 70,700 miles. On March 3, 1959, Pioneer 4, an American IGY space probe, was launched by a Juno II rocket and completed an Earth-Moon trajectory, passing within 37,000 miles of the Moon. It then fell into solar orbit, becoming America's first solar orbiter. About a year later, Tiros 1 was launched into Earth's orbit and became the first successful weather satellite for the United States. Then, on August 18 of the same year, 1960, Discoverer XIV was launched and became the first American spy satellite equipped with a Corona camera. On July 14, 1965, the US Mariner 4 sent back the first close-up images of Mars. The paragraph above explains some of the first satellites, spy satellites and probes sent into space to explore the unknown and "impossible". On May 5, 1961, Mercury Freedom 7 carried Alan B. Shepard, Jr., who was the first American astronaut. in space, in asuborbital flight. This first human spaceflight project in the United States was successfully completed during a dynamic 4.5-year period of activity. During this time, they met with more than 2,000,000 people from many major government agencies and much of the aerospace industry and combined their skills, initiative and experience in a national effort. Also during this period 4 and 2/3 six other manned space flights
