Abstract

GrainCams is a suite comprising two cameras: SurfCam and LevCam, developed by the Korea Astronomy and Space Science Institute (KASI) for the Commercial Lunar Payload Service (CLPS). SurfCam utilizes a light field camera with a Micro Lens Array (MLA) to capture 3D images of the fairy castle structures on the lunar surface. LevCam is designed to detect dust lofting above the lunar surface. Surviving extreme environments, including launch vibrations, lunar surface temperatures, space radiation, etc., necessitates thorough safety reviews, verification, and reliable ground testing of the system. This paper presents the comprehensive test results of GrainCams engineering qualification model (EQM), along with the cameras' performance following space environment tests such as Total Ionizing Dose (TID), Electro-Magnetic Compatibility (EMC), vibration/shock, and thermal-vacuum tests. Performance test analysis plays a crucial role in ensuring mission success. TID and EMC tests assess the space radiation endurance and electronic compatibility of the electrical components. The vibration/shock test evaluates mechanical stiffness and frequency characteristics during launch. Additionally, GrainCams undergoes temperature variation in the thermal-vacuum test to assess system performance under lunar operational conditions. Our demonstration confirms that GrainCams meet system requirements, and their performance in harsh environments is substantiated by the shared test results.
