Elisabeth Rose Murfin, also called Saint Elisa of the Prosperity and often referred to by spacers as Bloody Elisa, was copilot of a transport ship called the Prosperity chartered to move materials and people between the newly-colonized Jovian Moons and Earth. She sacrificed herself to save her ship and its passengers when the ship nearly broke apart during a return voyage, her body lost in space. Elisa's actions were highly publicized and made her a folk saint among both civilian and military pilots, often known as the "Patron Saint of Vacuum", her legend surviving through the 26th Century and beyond.
