PUNCH ENGINEERING MODELS (IMAGE) Southwest Research Institute Caption The Polarimeter to UNify the Corona and Heliosphere (PUNCH) mission achieved an important milestone, passing its internal system integration review, clearing spacecraft integration to begin in SwRI’s new Spacecraft and Payload Processing Facility. The team developed engineering models (EMs shown in background) to finalize integration processes and test procedures. EMs continue to support high-fidelity flight software testing and flight procedure/script validation (shown in foreground).
