-
A.
Thermal Infrared Sensor
chosen
The Thermal Infrared Sensor (TIRS) is a Landsat 8 instrument that measures Earth’s thermal radiation to monitor surface temperature and support applications such as water management and climate studies.
-
B.
Visible and Infrared Thermal Imaging Spectrometer
The Visible and Infrared Thermal Imaging Spectrometer (VIRTIS) is a spaceborne instrument designed to analyze planetary surfaces and atmospheres by measuring their emitted and reflected radiation across visible and infrared wavelengths.
-
C.
Longwave Infrared Camera
The Longwave Infrared Camera is an imaging device designed to capture thermal radiation in the longwave infrared spectrum, enabling temperature mapping and night or low-visibility observation.
-
D.
Infrared Camera
The Infrared Camera is a space-based instrument designed to capture and analyze celestial objects in infrared wavelengths, enabling detailed studies of phenomena such as star formation, interstellar dust, and distant galaxies.
-
E.
Thermal Emission Imaging System
The Thermal Emission Imaging System (THEMIS) is a multispectral infrared and visible-light camera on NASA’s Mars Odyssey orbiter used to map Martian surface composition, temperature, and geological features.
- F. None of above.
- G. Unsure - the case is ambiguous/there is not enough information to decide.
