Thermal Design and Testing of a Micro-Satellite for Infrared Astrometry (Nano-JASMINE)

This paper discusses the thermal design and testing for Nano-JASMINE. NanoJASMINE is a micro-satellite for infrared astrometry. Due to its small size, there are several strict requirements that should be met for the mission to be accomplished. The design to meet the requirements by the efficient using of a thermal shield and the multi-layered thermal insulation and the efficient components configuration is shown in this paper, as well as the simulation and thermal vacuum tests we did to for assessment. Since some of the requirements are difficult to even measure because of the necessity of the measurement accuracy, we used some unique methods to divide the whole test into several phases. NanoJASMINE’s thermal design shows that even a small satellite can also achieve strict thermal requirements with only passive control. This will make various scientific advanced missions possible at a low cost and a short development period.
