For a long time, outer space was conceptually and legally a no-man’s land – that changed on October 4th, 1967 when the Soviet Union launched a satellite called Sputnik into Earth’s orbit, triggering an international space race and calls for internationally binding laws to govern space exploration. Last amended in 1979, the outer space treaty drafted in 1967 facilitated smooth, peaceful interactions between nations capable of probing space. As the prospect of civilian space travel and settlement appears more accessible, international space law may be in need of revision. Joining us to discuss the field is Michael Listner, President of the International Space Safety Foundation.
