Nisar reflector going back to US for additional coating: Nasa
Nisar is almost finished. One of NASA's main contributions to the project is the application of a unique coating to hardware components on the satellite's 39-foot-diameter (12-meter) radar antenna reflector, which needs to be completed before launch. The reflector may experience higher temperatures in its stowed configuration during flight than previously anticipated, according to testing and analysis, which is why the special coating was added as a precautionary measure to mitigate any temperature increases that might potentially affect the reflector's deployment.
