Is space reserch worthwhile or a waste of resources?

Yes, I believe that space reserch is definitely beneficial to us. Many criticise it wastes of time and money. Priority should be given to other issues on Earth such as poverty and hanger. But I believe that space reserch plays an important role to improve our quality of life. Now I’ll focus two aspects of this issue.

First, we can expect great leap in technology. We will learn how to live and work in space. We'll make an effort to achieve space travel. Through this effort, we can defenitly achieve great leap in technology. Let's take semiconductor chips as example. Semiconductor chips used in space craft should work under harsh condition -- extremely temperature hot and cold. It's a big challenge to design robust micro chip which works properly. This effort enhances our technology.

Second, we can expect the secondary benefit for other pupose. Let’s take instant noodle for example. It is well suited for preservative food. As evidence, instant noodle was brought to space shuttle discovery. We would be able to experience three stars restaurant's taste in space craft/authentic Sushi/Tempura whatever. Through improvement of food technology, we can expect indirect benefit. It would contribute to hunger in Africa. It would improve oour food variety in daily life.
In conclusion, space reserch is a driving force to improve our quality of life.
