Odds are you've noticed that you can use your multi-tool to disassemble pretty much anything - space ship wreckage and Escape Pods, even your own Escape Pod, and their give up some pretty decent materials, especially right at the start.

I imagine after that you probably did some roaming and discovered an Alien Wreck. Who else turned their multi-tool on the wreckage to see what goodies disassembling it would provide?
