People have different opinion on spending money for space excavations. However, there are many benefits of this. Firstly, this study would find solutions for some of the problems of mankind. Moreover, long term survival of the human race significantly depends on finding another planet to move off from the planet earth; therefore, space explorations are inevitable. Similarly, humans have benefited from these since a long back ago. Take digital imaging techniques as an example, which were originally developed by NASA to study pictures of the moon, later on this technique used in diagnostic purpose.
