This site provides an interface to Goddard's Planetary Spectrum Generator (PSG), which can be used to generate high-resolution spectra of planetary bodies (e.g., planets, moons, comets, exoplanets). The spectroscopic suite can be also accessed remotely via the Application Program Interface (API). When requiring help on a specific input parameter, please click on the Help icon.
