Utah State University, Logan, UT
Abstract
The Active Thermal Architecture (ATA) is a sub 1U active thermal control system providing payload thermal support and setpoint thermal control for the Active Cooling for Multispectral Earth Sensors (ACMES) mission. Based on a single-phase fluid loop heat exchanger, the ATA features a micro centrifugal pump, an innovative working fluid, and a two-axis flexible rotary fluid joint coupled to a deployable tracking radiator. The ATA system leverages advanced Ultrasonic Additive Manufacturing (UAM) techniques to directly integrate the ATA system within the payload and CubeSat structure. NASA's Science Mission Directorate has selected the ATA system to fly on the ACMES mission. A 12U CubeSat technology demonstration funded by the In-space Validation of Earth Science Technologies (InVEST) program. The ATA will serve as payload support to the Hyperspectral Thermal Imaging instrument (HyTi). A high spectral/spatial density long-wave infrared (8-10.7 μm) instrument. HyTi also features advanced, onboard high-performance computing. The ATA will thermally support HyTi allowing for continuous operations. ACMES will also feature two student-led instrument development projects. A highly sensitive methane detector FINIS and a planar Langmuir/Impedance probe PLAID. ACMES will be a joint development effort between Orion Space, the University of Hawaii, and Utah State University.
