Author Tahir Rahman will sign copies of his book, We Came in Peace for All Mankind, Apollo 11 40th Anniversary edition.
Four decades ago Neil Armstrong and Buzz Aldrin left some mementos on the ancient lunar soil of the Sea of Tranquility. Among these was a small brittle silicon disc with microscopic messages of goodwill from 73 world leaders. In 1969, with only weeks left before the Apollo 11 liftoff, NASA worked feverishly on a crash project to miniaturize messages from American and world leaders to enshrine them on a material suited for the harsh environment of the Moon. This book reveals a never-before-told story of the disc, along with many rare and astounding photographs.
