Outer space


Since 1975 many people are exploring the outer space. since then countries are doing every thing to be the first to discover some thing new that related to the outer space, for example in 1960's Russia and the USA competed between them witch country will send the first shuttle to the outer space and in the1969 they also competed witch country will send the first men to the moon. 
Why is exploration of space so important to the humans?
-
On the one hand, space exploration is very important to the humans because it is expanding the knowledge of humanity. Thanks to space exploration humans invented many new things, like the satellites, the sunglasses were first developed by NASA. Since humans started to explore  outer space the technology advanced.
-
On the other hand, it is very dangerous and expensive to launch a shuttle to  outer space. We all witnessed the crashing of the Columbia space shuttle and the death of seven people. If it is so dangerous and expensive why do people continue with the exploration instead of investing time and money in problems that exist on Earth Like global warming and air pollution.
-
In conclusion, exploring outer space is an important thing that is expanding the knowledge of humanity, but in my opinion the money that we use for  space exploration should be
invested in improving the life on Earth.
It's a bit better, but still needs a lot of work. Read my remarks and correct your work once again. (75)
