L'TES

L'TES
L'TES is Lucy's thermal emission spectrometer. This infrared spectrometer performs measurements at wavelengths between six and 75 micrometres and will allow the Lucy team to determine the thermal inertia of the observed asteroids; that is, how well the bodies store heat, which will provide information about the composition and structure of the material on the asteroids' surface.
