CPF TVAC Testing and Integration on ExPA Complete!
The payload-level thermal vacuum (TVAC) testing has been successfully completed, marking a significant milestone for the CLARREO Pathfinder (CPF) project. Successful TVAC testing gives the CPF team confidence that the payload can operate in space environment conditions while on the International Space Station (ISS). After removal from the TVAC chamber, the Laboratory for Atmospheric and Space Physics (LASP) team in Boulder, CO completed integration of the CPF payload, including the Langley-built Power Converter Unit (PCU) and all flight harnessing, with the ExPRESS Payload Adapter (ExPA). The ExPA is the interface mechanism used to attach the CPF payload to the ISS. Following integration, a variety of payload performance tests will be conducted in preparation for payload storage.
