1. A method of supplying a receiving tank of a receiving spacecraft with a supply gas, said method comprising:
coupling a transfer line of a supply spacecraft in flow communication with the receiving tank on the receiving spacecraft, wherein the transfer line is coupled to a transfer tank disposed on the supply spacecraft, wherein the transfer tank holds a transfer quantity of the supply gas, wherein the supply spacecraft includes (i) a heating system coupled in thermal communication with the transfer tank and (ii) a transfer valve operatively coupled to the transfer line;
activating the heating system while the transfer valve is closed such that a pressure of the transfer quantity of the supply gas is increased; and
opening the transfer valve, wherein a difference between the increased pressure of the supply gas in the transfer tank and a pressure in the receiving tank causes a portion of the transfer quantity of the supply gas to flow through the transfer line to the receiving tank.
