What Does GPMS Stand For?

GPMS stands for Galileo Probe Mass Spectrometer

The Galileo Probe Mass Spectrometer (GPMS) is an analytical instrument designed for the measurement of the composition and properties of gaseous and particulate samples in planetary atmospheres. Developed for NASA's Galileo mission to Jupiter, the GPMS utilizes mass spectrometry techniques to identify and quantify various chemical species, providing critical data on the atmospheric composition and enabling a better understanding of planetary processes and environments.
