You can go in the broken door for a disc. There is one gramophone quite early in the level, in a cave, it's blacked out. I was looking for it for ages on the other side of the level.
Bonus Mission:
1) 1 Personal module, 1 Living quarters - upgrade to medbay asap
2) Take out the pirates on the right when you have 7 people (40 cost only)
3) Build a 2nd Personal module
4) When you have 10 people proceed to take out the bottom pirates
You don't need water/02/food. Be careful in the beginning not to lose people - grab them and drop them in your base, also mark close minerals. I upgraded my Personal modules to bunkers, but it didn't seem necessary.
