1. A system using water and ambient conditions for applying a thrust to a spacecraft, comprising:
a channel having an inlet and an exit; and
a resistive heater located at the inlet;
wherein the resistive heater is operable to generate a heat, the channel is operable to be blocked by a surface tension of the water in response to an absence of an application of the heat to the water, and the channel is operable to permit an ejection of the water from the exit to the ambient conditions in response to a change in a physical property of the water caused by an application of the heat to the water.
