January 27 is Holocaust Remembrance Day commemorating the day in 1945 when the Red Army freed more than 67,000 prisoners from the three Auschwitz camps.  However my goal with 365 Holidays a Year is to be International and to be Celebratory.  Posts of this sort will go into my next title, 365 Atrocities a Year, an equally if not more educational site.

On January 27, 1967, the United States, the United Kingdom, and the Soviet Union signed the Outer Space Treaty, formally the Treaty on Principles Governing the Activities of States in the Exploration and Use of Outer Space, including the Moon and Other Celestial Bodes.  The treaty is the framework for Space Law.  Among its principles, it bars states from placing weapons of mass destruction in orbit.  It does not, however, prohibit the placement of conventional weapons.  It limits the use of the moon to peaceful purposes, expressly prohibiting weapons testing, military maneuvers, or bases.   102 countries are party to the treaty and another 27 have signed the treaty but have not completed its ratification.
