Thermal emission spectrometer

Thermal Emission Spectrometer) instrument indicated the metallic nature of the rock [340]. Observations made with the panoramic camera and the microscopic image revealed that the surface of the rock is covered with pits interpreted as regmaglypts and indicate the presence of a coating on the surface. The a-Particle-X-ray spectrometer (APXS) and the Mossbauer spectrometer were used to investigate the undisturbed and the brushed surface of the rock. Based on the Ni and Ge... 

The APXS and MB in-situ dataset from individual stratigraphic units can be placed in a geologic context when reconciled with the MER remote sensing Miniature Thermal Emission Spectrometer (Mini-TES McSween et al. 2008) and Panoramic Camera (e.g. Farrand et al. 

It is obvious from these experiments that the absorption spectrum of the Martian red surface can be simulated reasonably well by a non-unique variety of Fe rich phases or their mixtures as can the weak magnetism, so that a positive identification will probably only be possible, following further in situ analyses and/or sample return and analysis in the lab.Two Mars Exploration Rovers (MERs) are due to arrive at Mars in 2004 and will attempt to analyze rocks and soils on the surface using several small spectrometers, including PanCAM (an extended visible region spectrometer), MiniTES (a thermal emission spectrometer), APXS (alpha proton X-ray spectrometer measuring the major elements), Mossbauer (run at current local temperature), as well as a 5-level magnet array similar to that on-board the Pathfinder Lander.

Spectrometers on several spacecraft have provided information on the mineralogy of the martian surface, but only one set of spectral data is sufficiently quantitative to be recast into geochemistry. The thermal emission spectrometer (TES) on Mars Global Surveyor and the thermal emission spectrometer imaging system (THEMIS) on Mars Odyssey have provided global mineral mapping, and linear deconvolution allows the...

The Mars Global Surveyor launched from Cape Canaveral in November 19%. It reached Mars orbit in 1997. One of five instruments on board was an IR emission spectrometer, called a thermal emission spectrometer. The spacecraft completed its mapping mission in 2001. providing measurements of the Martian surface and atmosphere. The Mars rover Spirit has a... 

These are applicable to the 10 cm spectral resolution measurements obtained by the Thermal Emission Spectrometer carried on the Mars Global Surveyor spacecraft (Christensen et al., 1998), and points on both sides of the 15 pun CO2 band are included. Rapid calculation of atmospheric transmittances is required for temperature retrieval from a large volume of spacecraftmeasurements, and the A -distribution method is used (Goody Yung, 1989).
