High Altitude Balloon Phase Change Ballasting System

A high-altitude balloon system configured to maintain an altitude across environmental conditions by controlling phase changes of a multi-phase ballast gas, the high-altitude balloon system comprising:

• a balloon, comprising a gas, wherein an environmental condition affecting a pressure of the gas within the balloon;
• and
• a ballast component, fluidically coupled to the balloon, the ballast component comprising:
• a tank, coupled to the balloon, the tank comprising the multi-phase ballast gas in a liquid phase;
• an environmental sensor, coupled to the tank, configured to measure the environmental condition;
• and
• a controller, coupled to the environmental sensor, the controller configured to:
• detect the environmental condition affecting the balloon;
• responsive to detecting the environmental condition, determine the pressure changes from an initial pressure to a modified pressure;
• and
• control a phase change of the multi-phase ballast gas to change the pressure from the modified pressure to a compensated pressure, wherein the phase change causes the multi-phase ballast gas to adjust the compensated pressure towards the initial pressure.

A non-transitory computer-readable medium, storing computer program instructions that, when executed by a processor, cause the processor to:

• detect an environmental condition affecting a high-altitude balloon, the environmental condition affecting a pressure within the high-altitude balloon;
• responsive to detecting the environmental condition, determine the pressure changes from an initial pressure to a modified pressure;
• and
• control a phase change of a multi-phase ballast gas to change the pressure from the modified pressure to a compensated pressure, wherein the phase change causes the multi-phase ballast gas to adjust the compensated pressure towards the initial pressure.
