title: RECYCLABLE AND SUSTAINABLE METALLIC MATERIALS FOR SPACE STRUCTURES: TOWARDS A CIRCULAR SPACE ECONOMY
abstract: The growing number of satellites and spacecraft in near-Earth orbit has intensified concerns about material sustainability and space debris generation. Traditional space structures, often made from aluminium and titanium alloys, are typically designed for single-use missions, leading to a growing accumulation of defunct materials in orbit. This paper explores the potential of recyclable and reusable metallic materials - specifically titanium and aluminium alloys - for application in next-generat
