Abstract
The Star-Planet Activity Research CubeSat (SPARCS) 1 far ultra-violet (FUV) instrument will be tested and thermally characterized in a thermal vacuum (TVAC) chamber. The development and understanding of the thermal characteristics of the TVAC system are crucial to the verification of the thermal capabilities of the SPARCS payload. A TVAC chamber for testing FUV CubeSat instruments is in development at Arizona State University (ASU). The chamber will be used to test the SPARCS payload and future CubeSat missions. A thermal model of the thermal chamber has been developed for use with the SPARCS payload to correlate the model to test data. Correlating the model to test data will provide more realistic temperature predictions and reduce risk to the mission. The chamber model will be used along with the payload thermal model to determine preliminary test procedures creating a more realistic timeline for the testing.
