Just did that yesterday, nothing happened, and i'm pretty sure this has already been done a million times before
Also tried to place an UA right beside some outcrops and meteroids on the surface and then shooting at them, but also with no results. Did that on several planets in the Merope system.
Another thing.. some days ago i was also pretty curious about that misspelled barnacle file in the game folders so i also took a look at the filenames and there was some very little information i found which might be helpful.
Not sure if this is "legal" information, so i'll put it into spoilers (as mentioned, i only looked at the filenames and didnt try to open or decrypt any files). Nevertheless, it didn't helped me so far
