Abstract

The Thermal Control System (TCS) of the Plankton, Aerosol, Cloud, ocean Ecosystem (PACE) Ocean Color Instrument (OCI) incorporates two propylene Loop Heat Pipes (LHP). A Thermal Vacuum (TVAC) test was conducted at NASA Goddard Space Flight Center to characterize the fully integrated OCI in the test-as-you-fly configuration. Within the constraints of movement of the OCI in the TVAC chamber, an elaborate series of trending and calibration tests have been accomplished. This paper presents the measured LHP performance along with lessons learned.
