Thermal Design and Analysis of Europa Clipper’s Radio Frequency Module

NASA’s Europa Clipper (EC) will conduct a series of close flybys of Jupiter’s moon Europa and investigate if its ice-capped ocean could harbor conditions suitable for life. Set for launch in 2023, the spacecraft is currently under development in its Detailed Design Phase. Challenging mission requirements and environments, including accommodation of a solar array power architecture, a high ionizing radiation environment, and a 0.65 to 5.6 AU solar distance range has necessitated base-lining a mechanical pumped fluid loop (MPFL) architecture known as the Heat Redistribution System (HRS). This paper will present an overview of how the HRS is applied to the Radio Frequency (RF) Module of EC.
