Visible and Infrared Mapping Spectrometer (VIR)

The Visible and Infrared Mapping Spectrometer (VIR) is a scientific instrument used on spacecraft to analyze the composition of planetary surfaces and atmospheres. It works by capturing light reflected or emitted from a target across visible and infrared wavelengths. By examining this light, VIR can identify specific minerals, rocks, and other materials based on their unique spectral signatures. This helps researchers understand the geology, surface processes, and environmental conditions of planets and moons, providing detailed maps that reveal the composition and diversity of extraterrestrial terrains.
