Time. This is the one cost that presents difficulty to this study. The time it takes to gather Thargoid artifacts makes any mistake or unexpected disruption tedious at best.
I had gathered the following:
4 tonnes of Thargoid Resin
2 tonnes of Meta-Alloys
3 tonnes of Thargoid Biological Matter
1 Thargoid Probe
12 Thargoid Links
2 Thargoid Sensors
3 tonnes of Thargoid Technology Samples
With these in hold, corrosion resistant cargo racks are wonderful, I made signalled to the Thargoids that I was available for trade. How? Hyperspace jumping, of course. A Medusa was eager to get my attention and I obliged with my usual caution, you gotta have a shutdown field neutralizer. As she opened the communication channels of light and sound, I presented the cargo to her. After 4 items were gathered the familiar alert came as a second interceptor jumped in. To my dismay, the window opened in extreme proximity and my ship was launched nearly 8 kilometers from the Medusa. By the time I was able to move towards the area the Medusa was leaving and the other interceptor collected the last few items. I could not get close enough to examine to second.
I'll see what happens with these 50 "volunteers" I gathered before I hunt for more Thargoid commodities.
