Whether your ship runs out of fuel in the middle of an expedition, or your oxygen runs out in the middle of an extraction, the Earth Alliance has deployed rescue teams to fix this ... little impasse.
If your ship runs out of fuel, you can always request a rescue service which will send you a refueling drone ship and thus buy the necessary fuel to continue your trip.
If you run out of oxygen in the middle of an extraction, V.C.T.R. will send a distress alert and drag you to the ship awaiting reinforcements.
The payment to be paid for rescues will be calculated based on the market prices and depends of which service they want to pay to be rescued. Even in the future your friends could rescue you!
