The short, 17-article document serves as a "constitution" for the worlds beyond Earth's atmosphere. It was ratified October 10 of the same year, which places us in the midst of a yearlong 50th anniversary celebration. To date, 105 countries have since signed it.
The treaty boasts a half-century of success, but with countries expanding and intensifying their exploration missions, private companies commercializing space travel, and an increasingly hostile international political environment, can humanity be trusted to continue a peaceful co-existence in outer space?
This question was recently posed by Jill Stuart, a fellow at the London School of Economics and Political Science, in an op-ed for The Conversation. She suggested the treaty needs updating and certain clarifications in order to adequately address the inevitable challenges future centuries will face.
