I read about SpaceX plan to send humans on Mars by 2020. But there are some flaws,flaws that we don't know, flaws whose answers are not yet to be explained or studied. Like; what will be the effect of Mars environment on human psychology. It seems only technology can't make this happens. One should know and study every aspect of this tarvel and living on red giant from technology to sociology. So we can say this journey compiles the term "socio-technological" journey.

I think we should try to make this earth peaceful instead of thinking to leave it and live out there in outter space,alone, in order to seek peace. If you fail to get peace prevailed at place you are living in this time how would you expect to have peace in a space nation with same human who are causing the evil acts ruling on the face of earth? Only thing we should do is to be united and wipe out evil.
