Space Probe Plaque

In 1971, NSSA (the Nova Scotia Space Agency) launched the Champlain 2 probe, the first spacecraft to enter interplanetary space. In case it was ever intercepted by intelligent aliens, Champlain 2 carried a plaque depicting a trio of Nova Scotians and offering precise directions to Halifax.
