That’s the point of the game - it doesn’t tell you where to go and what to do because you’re meant to explore the environment yourself. And the debris you scan, the screenshots you take, and the thrills that you get - are the real reward here, and not some goal that game artificially imposes on you. So I think you were just playing it wrong.

Eh, where is the source code then?

Edit: It appears this is what I want.
