Claim 23:
24. A vehicle system comprising:
a pressure vessel capsule comprising:
a superior surface at a first end;
a structural frame comprising a set of support members extending between the first end and a second end; and
a set of windows attached to the structural frame, each window extending between a respective pair of adjacent support members of the set, wherein the set of windows and the structural frame cooperatively define a cabin interior which is configured to be fluidly isolated from an exterior environment;

a set of mounts at the superior surface of the pressure vessel configured to tether a lighter-than-air balloon to the pressure vessel capsule;
a radiator mounted to the pressure vessel capsule, arranged outside the cabin interior and offset from the superior surface, wherein the radiator comprises a plurality of petals radially encircling a central axis;
a first heat exchanger mounted within the pressure vessel capsule;
a cabin air loop, comprising:
a cabin air manifold fluidly coupled to the first heat exchanger; and
a fan configured to circulate the cabin air through the cabin air manifold; and

a first refrigerant loop comprising a refrigerant, the first refrigerant loop fluidly coupled to fluid channels within a first subset of the plurality of petals and configured to thermally couple the first heat exchanger and the radiator; and
a second refrigerant loop, fluidly isolated from the first refrigerant loop, which is fluidly coupled to fluid channels within a second subset of the plurality of petals, wherein the first and second subsets are disjoint.
