Space missions require materials that can function under extreme conditions. In this Focus issue, we highlight the efforts of the European Space Agency to design and test appropriate materials for space exploration, while taking a look at the properties needed for the ambitious Breakthrough Starshot initiative.
Space missions require materials that can preserve functional integrity under extreme conditions of heat, impact and radiation. This Comment outlines the materials properties needed for some of the most ambitious space missions and presents the design and testing principles before their incorporation.
This Perspective explores the optical, mechanical and thermal properties required to successfully design an ultralight spacecraft that can reach Proxima Centauri b, which is the goal of the Starshot Breakthrough Initiative.
