Help no spoilers

Hey guys, I've found myself with all the entries unlocked so far in the log, but nothing left to visit. I visited the sixth location and the solar station, and although I've figured out how things went, I can't figure out what the game is asking me to "get to the end." I guess I have to stop the explosion or something similar. Can anyone give me a clue that won't give me the solution, but might put me on the right path? Thank you all so much.
