CuRIOS-ED: expected on-orbit performance and early flight data from a space-based CMOS imager

CuRIOS-ED (CubeSats for Rapid Infrared and Optical Surveys–Exploration Demo) is an optical imaging payload launching on a 12U CubeSat in June 2026 as the first technology demonstration for the CuRIOS constellation concept. The payload uses commercial components, including an Atik apx60 camera with a Sony IMX455 detector. CuRIOS-ED was fully integrated into the spacecraft in November 2025. In addition to camera-level characterization, we performed system-level thermal testing of the CuRIOS-ED payload to quantify thermal gradients and detector cooling behavior under flight-like conditions. In this talk, we present the expected on-orbit performance of CuRIOS-ED based on these measurements, including predicted noise and thermal stability. Additionally, we outline the commissioning plan and expected science returnables. Early telemetry and images—if available—will be used to validate estimates and demonstrate the viability of low-cost CMOS imagers for future survey missions.
