The Thermal Emission Spectrometer (TES) is an instrument designed to measure thermal infrared radiation emitted from planetary surfaces and atmospheres. It is typically used in planetary science missions to analyze the composition and physical properties of planetary materials. ### Key Features and Functions of TES: 1. **Spectroscopy**: TES operates on the principle of spectroscopy, which involves measuring the intensity of infrared light at various wavelengths. This allows scientists to identify specific minerals and chemical compounds based on their spectral signatures.
