What Does GPHS Stand For?

GPHS stands for General Purpose Heat Source

GPHS, or General Purpose Heat Source, refers to a versatile and reliable thermal energy source designed for various applications, particularly in space exploration and satellite systems. It harnesses radioactive decay to produce heat, which can be converted into electrical power or used directly for thermal management, providing a consistent energy supply in environments where conventional power sources are impractical. GPHS units are engineered for longevity and safety, making them suitable for long-duration missions beyond Earth.
