On January 27, 1967, the United States, United Kingdom and then-Soviet Union, signed the Outer Space Treaty. 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?
