Movie quote
I knew previous coworkers that worked on the Webb program and was brought in as a consultant on one problem during assembly (not design where I normally worked). I have also worked on numerous other satellite programs where I worked on every aspect as a Systems Engineer including Anomaly Detection and Resolution. This is not the main sensor on Webb and it could be cleared up by working the mechanism back and forth. But I can tell you that they will have the diffraction grating near the most valuable setting when they are trying to resolve the sticky operation. I am not involved in this issue at all, just drawing on past experience that includes Initial On-Orbit Testing of satellites that had anomalies.
