Space Rocket History #437 – Mariner 10 – Venus & Mercury

Scientists had long been intrigued by Mercury, the innermost planet of our solar system. Despite its proximity to the Sun, Mercury remained largely unexplored, with many questions remaining about its surface features, geological composition, and magnetic field. The scientific community recognized the need for a dedicated mission to study Mercury up close and unlock its secrets.
