The Thermal Emission Spectrometer is a type of passive spectrometer that can identify the composition of surfaces by analyzing its infrared spectrum. // Headline text Bold text:For Acoustic uses in spectrographs of sound waves, see below. ... Image of a small dog taken in mid-infrared (thermal) light (false color) Infrared (IR) radiation is electromagnetic radiation of a wavelength longer than that of visible light, but shorter than that of microwave radiation. ... Legend: γ = Gamma rays HX = Hard X-rays SX = Soft X-Rays EUV = Extreme ultraviolet NUV = Near ultraviolet Visible light NIR = Near infrared MIR = Moderate infrared FIR = Far infrared Radio waves: EHF = Extremely high frequency (Microwaves) SHF = Super high frequency (Microwaves) UHF = Ultrahigh frequency VHF = Very high frequency HF = High frequency...

Three types of TES data are collected: hyperspectral thermal infrared from 6-50µm, broadband thermal infrared (5-150 µm), and visible/NIR (0.3-2.9 µm) radiometric measurements. The microbolometers are arranged in a 2x3 array and each detector has a field of view of ~3 x 3 km at the surface of Mars. The field of view is the part of the observable world that is seen at any given moment. ... For the Roman god, see Mars (mythology). ...

Thermal emission spectrometers have been used in the Mars Observer, Mars Global Surveyor, and Mars Exploration Rover missions, all of which were developed by Phil Christensen at Arizona State University. Mars Observer, launched in September 25, 1992, was the first of the Observer series of planetary missions, was designed to study the geoscience and climate of Mars. ...
