Clelio Ferreira Leite was born in Lisbon Portugal in 1964, and has since then continued to inspire and surprise both peers and superiors with his ingenuity and industriousness. It was from these humble beginning that Clelio would go on to an incredible career involved with marine and aerospace technology. As a teenager he became an enthusiast amateur astronomer building is own observation instruments and by was launching solid rockets that reached high in the troposphere. When he grew up, he would do just that, and even help manage and develop the technology that makes it possible.
