Nasa,Part 1, Why we must continue the manned space program

Ever since the 1970's people have question the need and relevance of NASA and the manned space program. Here are a few reasons why we need NASA and manned space exploration. 1.( assumption: NASA contributes nothing to our advancement). This assumption is wrong in many ways, first lets think of a few advances and technologies that have been made in the last 30 years. Advancement number 1 fire fighting SCBAs, without the NASA moon missions fire fighters would not have the ability to enter burning buildings like they do now. The breathing apparatus they wear were modeled from the air tanks astronauts like Neil Armstrong wore on the moon. Advancement 2) GPS: without NASA and without the manned space program we would not have this technology we take for granted and here is why. First it was NASA that sent America's first satellite into space. Second it take astronauts to maintain these GPS satellites or in otherwords without the manned space program there would be no GPS. Another reason to keep NASA and manned exploration is this. One day our sun will exhaust it fuel when that happens (in a few billion years) the only way to survive will to leave our solar system. Third it is our nature to set foot in new lands whether here on Earth or in space. This is what make us human, the need to to seek out and explore new areas of our planet and new reaches of our universe. Another statement against manned space exploration is that it is dangerous. This is true, but any exploration whether on Earth or in space is inherently dangerous. So, to end manned exploration because of the danger is like telling Christopher Columbus that he cannot go to the New World because it is dangerous. Had Spanish queen Isabella said this there would have been no United States and we would still be taught the Earth is flat. But because she allowed and financed the trip we now have knowledge and countries that did not exist before Columbus's trip. In closing I say that we must continue NASA and manned exploration because it is in our nature to explore and it is what makes us human.
