The Blockhouse, the Rover, the Blockhouse.

I'm guessing it was an overheat, the cooling system vents getting clogged with dust when i fell. I know that i'm within a stone's throw of the block house. If i can find it, maybe i can pressurize it clean out the vents. Or maybe my open oxygen supply will keep me alive long enough to get the calms working. But then i'd be right back to square one, only with two hours less oxygen.
