> SpaceX's next Crew Dragon mission (Crew-5) will fly with a different, updated heat shield structure after a new composite substrate failed acceptance testing

I don't know what "new" or "different" or "updated" or "structure" mean then anymore.

Looking at other articles, nobody else mentions an updated structure. I think that was a misunderstanding. This was a manufacturing defect caught in testing and they used a different unit as a result.
