Greetings! First of all, english isn't my native language, so thanks in advance for being patient with me.
With interest I'm following this thread since the barnacles have been discovered. Unfortunately I cannot land on planets and search by myself while, lets say, my SRV is too old and did not pass the MOT.
Here are my two cents and sorry if it has been mentioned already.
- Regarding the symbol on the barnacles I also hold the opinion, that it represents the Barnard's loop looked from behind, towards Sol (roughly). It somehow looks like a person from top, trying to catch a ball. The arms of the person fit quite well to Barnard's loop, the head of the person could be Orion inline with Pleiades, Flame ,Running man and Horsehead nebulae. The question is.... which location is represented by the 'ball' and what can we find there? Could be Witchhead nebula as mentioned before, but the shape of the 'ball' does not fit very well to it.
- Assuming the symbol on barnacles is some kind of a map from an alien species (friendly or not), I do not think it will tell us where they are from. What could they get out of it? Even mankind isn't so stupid to invite aliens to their home planet earth - why should aliens do so? Ok, maybe they are bored (very). In my opinion the symbol (the map) could serve a different purpose.
- I too think that barnacles and UAs are from the same alien species and 'work together' somehow. Maybe UAs are born of the barnacles and spit out to space by them. That seems plausible to me. Single UAs obviously collect information (maybe not only) about ships. A shell of UAs (around Merope) could act as kind of range extender for information which is send out, or orders which are received. Do we know where the opening of the shell is pointing to?
- Regarding the damage that UAs do to our ships and stations I don't think that necessarily means the alien species is hostile. Just speculation. A flu could be quite deadly to the alien species, but without knowing about that, somebody could infect them on first friendly contact. The aliens also might think we intentionally attacked them with bioweapons.

Michael
