The launch of Sputnik 1 had surprised the US as this launch was coupled with the magnificent failure of the USA”s first two attempts for the launch of Project Vanguard. The launch of Sputnik 1 had had a very positive impact in the space research world. Firstly, it led to the up come of Advanced Research Projects Agency, DARPA, and NASA. Besides, it had also inspired various youngsters to form a generation of engineers and scientists.
