The Arthur C. Clarke Institute for Space Education is dedicated to delivering education programs world-wide that address our planet, its health, and our ability to venture beyond Earth and understand our place in a greater cosmos. It is with profound honor and a deep sense of purpose that we help continue Sir Arthur C. Clarke’s legacy.
The Clarke Institute for Space Education is the international arm of the National Center for Earth and Space Science Education in the USA, which recognizes that all humanity is on a journey aboard spaceship Earth, that the story of our existence knows no national borders, and it should be the birthright for all our children to understand that the explorer lives within them.
