Thermal Emission Spectrometer
The Thermal Emission Spectrometer is a class of infrared spectrometer used in planetary science by agencies such as NASA, European Space Agency, and institutions like the Jet Propulsion Laboratory and the California Institute of Technology. Developed through collaborations involving centers such as the Ames Research Center and universities including Arizona State University and Brown University, these instruments have been deployed on missions led by programs like Mars Global Surveyor, Mars Reconnaissance Orbiter, and projects associated with the Lunar Reconnaissance Orbiter. The instruments support investigations tied to principal investigators from organizations such as Smithsonian Institution and laboratories including the Planetary Science Institute.
Thermal Emission Spectrometers derive from heritage in missions like Mariner 9, Viking program, and later evolved with contributions from teams at Cornell University and University of Arizona. They fit within payload suites managed by mission directors from Jet Propulsion Laboratory and science teams associated with NASA Goddard Space Flight Center and international partners such as Centre National d'Études Spatiales and University College London. Thermal emission instruments interface with mission elements overseen by program offices such as Discovery Program and Mars Exploration Program and complement sensors developed at institutions like MIT and Caltech.
Designs reflect engineering practices from facilities including Lockheed Martin and Ball Aerospace, with optics often fabricated using processes developed at Sandia National Laboratories and Brookhaven National Laboratory. Key components—detectors, interferometers, and telescopes—trace technological lineage to devices produced at labs such as Lawrence Berkeley National Laboratory and Jet Propulsion Laboratory. Detector materials and readout electronics are influenced by semiconductor research from Bell Labs and packaging techniques from Raytheon Technologies. Mechanical structures are tested in environmental chambers at Johnson Space Center and vibration facilities at Ames Research Center.
Operation employs physical principles formalized by scientists associated with institutions like Max Planck Society and mathematical formalisms used by researchers at Princeton University and Harvard University. Typical spectral ranges span mid-infrared bands used in studies similar to those from Infrared Astronomical Satellite and instruments developed at University of Colorado Boulder; the spectral resolution and radiometric sensitivity are designed considering standards promulgated at organizations like National Institute of Standards and Technology and measurement techniques taught at Massachusetts Institute of Technology. Optical layouts often use interferometry concepts refined in collaborations with researchers at Stanford University and University of California, Berkeley.
Calibration pipelines are informed by practices from teams at NASA Goddard Space Flight Center and software frameworks that echo systems from European Space Operations Centre and academic groups at University of Oxford. Radiometric and spectral calibration reference blackbody sources trace to standards at National Physical Laboratory and processing algorithms employ techniques developed by researchers at Carnegie Institution for Science and Observatoire de Paris. Data formats and archiving follow conventions used by archives like Planetary Data System and European Space Agency Archive, with analysis tools originating from research groups at University of Arizona and visualization approaches influenced by work at Jet Propulsion Laboratory.
Notable flight instruments include those carried by Mars Global Surveyor and successors linked to missions such as Mars Odyssey and Mars Reconnaissance Orbiter, developed by teams from Lockheed Martin and Jet Propulsion Laboratory. Other deployments have involved collaborations with institutions on missions like Lunar Reconnaissance Orbiter and programs coordinated with Indian Space Research Organisation and Roscosmos personnel. Science teams have included researchers from Brown University, Arizona State University, Cornell University, and international investigators from University College London and University of Paris.
Results have influenced studies published by authors affiliated with Nature (journal), Science (journal), and specialty journals managed by the American Geophysical Union and European Geosciences Union. Applications include mapping mineralogy on bodies studied by missions coordinated with NASA and interpreted by scientists at Smithsonian Institution and Planetary Science Institute, constraining atmospheric properties in studies associated with European Space Agency teams, and informing landing site selection in campaigns run by Mars Science Laboratory and project offices at Jet Propulsion Laboratory. The datasets have been used by researchers at California Institute of Technology, MIT, Princeton University, and University of Arizona to advance models of surface composition connected to work from Smithsonian Astrophysical Observatory.
Limitations arise from resource constraints managed by mission planners at Jet Propulsion Laboratory and technology readiness levels assessed by organizations like NASA and European Space Agency. Challenges include thermal control demands handled by engineering groups at Johnson Space Center and signal-to-noise issues studied by teams at Lawrence Livermore National Laboratory and Sandia National Laboratories. Operational constraints during missions such as Mars Reconnaissance Orbiter require coordination with mission operations at Jet Propulsion Laboratory and data downlink scheduling managed by facilities like Deep Space Network.
