Thank you for the extra information! The way the original article I read sounded, they lost contact and had no idea when. So that at least gives some hope that they have enough of a window for rescue based on how much O2 they generally carry on board. But if it just went dark, a lost of ship power is the only thing I can think of that would cause that, which means sitting at the bottom of the ocean. Would life support even help at that point? Nothing to pump O2 or scrub CO2 out of the air.
