Currency and their Changes

I came up with this article while thinking about our recession. Originally, the human civilization used the barter system, in which one type of good was traded for another. Then, the first currency of gold, silver and other metal coinage was made. The United States was one of the first to use paper money, which has no value in some countries but is still used. As a civilization moves into space, how might its 'currency' change? Right now our rockets and satellites are powered by nuclear fusion, hydrogen and liquid oxygen. We plan to mine for diamonds, gold water and other precious materials as we colonize space. In the future, humanity might use an immensely blown-up barter system as larger amounts of materials are discovered. For example, Jupiter might trade hydrogen for some carbon dioxide from Venus. As humanity continues to expand, we will also expand our trading and financial horizons.
