[spoilers!] Help with archeologist achivement?

[Shu]

I'm currently trying to figure out why I can't get a connection between Gravity Cannon and Tower of Quantum Knowledge.
Is there something I'm missing?

I checked the surroundings of the Grav Cannon and the Tower, I've read all texts I can find, even got the ship from solanum from the Moon and launched it. I have no clue how to get the last tiny piece of puzzle in order to get the achivement.

Can somebody help?

EDIT: There is no connection between Gravity Cannon and Tower of Quantum Knowledge.
I was missing Dialog from Chert which wasn't mentioned by the ship log. (Bug?)
I've got the achivement now.

Looking for an archeologist video on youtube should solve your issue.

it seems that there is no connection between them. I've been missing some specific dialog from chert. Looks like a bug to me. Well, what ever. I've got the achivement now.

Due to your comment I randonly stumbled upon this video.
