Your current objective is to find a way to get through the main door. To do it, go through the door shown in the screenshot and you'll restore the power.
Go back to the main door and you'll find a stairwell on the left, go upstairs.
After you go up, save the game and go to the next room on front of you to find a journal.
Get out of the room and enter the door on the left, then right. You'll see a corpse and a maintenance jack that you need to open the main door. To get to the tool, use the ventilation shaft on the right because the door is locked.
Take the maintenance jack from the corpse. Take his keycard and a journal. To get out of the room, use the maintenance jack on the door.
Get out of the room and enter the next one. You'll find materials and another journal. Use the maintenance jack to get there.
Go to the main door. Before you open it, it's a good idea to explore the rooms on the right that require the maintenance jack. In the room, you'll find scraps and materials for crafting.
After you collect the items, go back to the main door and open it.
Note: While exploring the station, you've seen some doors that can't be opened (they require an ion cutter). They will stay closed until you find the cutter.
