Yeah, but why fix a rocket that you never launch? Unfortunately, once that puzzle's completed, it doesn't ever change visually again, and there's no benefit that can be conferred by completing it.
the rocket would landon a planet and get a space rock (pearl)
But we can only make graphical changes. There would be no implication that the rocket is the reason that the pearl appeared, except that experienced players know that the puzzle works that way. We can't even add or edit a text notification.
Then again, this is something I didn't like about the VV statue puzzle, either; the reason building a statue should expose a pearl was never clear to me. Maybe I blow through the game's opening text notifications too quickly?
