➀ Fraunhofer Heinrich-Hertz-Institut (HHI) has developed a new method for producing thermally emissive surface structures using reactive gas-assisted nanosecond laser processing on aluminum alloys for spacecraft electronic boxes. ➁ The NanoBLAST project, funded by the Federal Ministry for Economic Affairs and Climate Action, aims to scale up and commercialize this technology. ➂ The project focuses on optimizing laser parameters and adapting the laser setup for real components with curvatures and recesses, marking a significant advancement in space-appropriate thermal regulation.
