It is now possible to visit the Academy before you do any of the missions out in space. So I tried that. Got the Boothby accolade. Then I beamed directly to sector space. Thus the Undock part of the Stranded In Space didn't complete.
This should be changed to allow this sort of exit to space.
Sure all it took was going back to Sol System and then warp out again. But imagine someone who haven't played the game before. They might not think of that right away.
