"The International Space Station Program brings together international flight crews, multiple launch vehicles, globally distributed launch and flight operations, training, engineering, and development facilities, communications networks, and the international scientific research community."
In an easily accessible and sufficiently succinct overview, NASA presents summaries of a collaboration designed to examine space exploration and how it can benefit mankind. Operating the space station and the responsibility for the hardware sent to the ISS are 5 partners: "...the Canadian Space Agency, the European Space Agency, the Japan Aerospace Exploration Agency, the National Aeronautics and Space Administration, and the State Space Corporation 'Roscosmos' . "
The space program and human exploration are moving forward with Moon to Mars initiatives (and spacecraft launching every few days).
This is a good departure point for where we are headed and how we hope to get there.
