Materials Science
Materials science is the study of what things are made of, how they behave, and how to create new materials with specific properties. It's essential for developing stronger, lighter, or more heat-resistant components for spacecraft.
TECHNICAL DEFINITION
Materials science is an interdisciplinary field investigating the synthesis, processing, structure, properties, and performance of materials, crucial for developing advanced alloys, composites, and ceramics for aerospace applications under extreme conditions.
BACKGROUND
The Korea Aerospace Research Institute, established in 1989, is the aeronautics and space agency of South Korea. Its main laboratories are located in Daejeon, in the Daedeok Science Town. KARI's vision is to continue building upon indigenous launch capabilities, strengthen national safety and public service, industrialize satellite information and applications technology, explore the Moon, and develop environmentally-friendly and highly-efficient cutting-edge aircraft and core aerospace technology. Current projects include the KSLV-2 launcher. Past projects include the 1999 Arirang-1 satellite. The agency was founded in 1989. Prior to South Korea's entry into the Institute for Advanced Engineering (IAE) in 1992, it focused primarily on aerospace technology. As of May 2024, KARI is an affiliated research institute of the Korea AeroSpace Administration.
