International space station

When i see a documentary about building International Space Station or ISS. I realize that it not easy to build a huge superstructure that need build in hustle environment.To build ISS it need all country in this world to collaborate with one another whether have same ideology or not.The International Space Station will be symbol of peace and humanity of human kind .Beside that,by building ISS,we can have more cutting edge technology that will be applied to daily life.I hope this international project will be the milestone of human in space exploration.
