This thesis investigates designing and verifying a new frame for the HyperScout, a hyperspectral optical instrument used for earth observation. Due to changes in the instrument's size, the research aims to develop a frame that meets the thermal and structural requirements. The study explores six design concepts, focusing on innovative materials like titanium, PEEK, and wood and advanced manufacturing techniques such as 3D printing. Three promising designs were selected for further development and underwent structural, thermal, and optical testing to ensure their suitability for space conditions. Finite Element Modeling (FEM) and Thermal Vacuum Chamber (TVAC) tests were used to simulate the harsh environment of space and validate the designs. The findings highlight the strengths and limitations of each material and design approach, with recommendations for future research in optimizing spacecraft components.
