The story of Project Orion

A secret Cold War project set out to build a 4,000-ton spacecraft powered by nuclear bombs, aiming to reach Saturn in just five years. Engineers designed ships as tall as the Marriott Hotel, relying on thousands of nuclear blasts for propulsion. The effort drew on top hydrogen bomb experts and absorbed ARPA's first million-dollar grant, but was ultimately buried by secrecy, internal opposition, and public risk. Today, the project's legacy lingers as both a cautionary tale and a hidden technological option for planetary defense.
