1. A heating system for a component within a compartment of a spacecraft, the heating system comprising:
a fuel source comprising hydrazine;
a gas generator in fluid communication with the fuel source, the gas generator comprising a catalyst, wherein the catalyst is configured to decompose the hydrazine and generate an exhaust gas;
a heat sink thermally coupled to the gas generator and configured to receive heat from the exhaust gas of the gas generator, wherein the heat sink is thermally coupled to the component within the compartment of the spacecraft to transfer heat from the exhaust gas to the component; and
a tubing indirectly coupled to the component and configured to function as another heat sink and to direct heat from the exhaust gas to the component.
