NIR Camera

Near Infra-Red multispectral Camera

Objective: Construct an equivalent MER PANCAM from readily available commercial parts for use of science and study of Earth’s atmosphere and geological features.

NIR Camera

MER Pancam – Overview

 

  • A pair of high resolution, stereo, color CCD cameras present in Spirit and Opportunity Mars Exploration Rovers (MERs) to obtain panoramic multispectral images of the Martian sky and surface.
  • Geology/Geomorphology: Past history of a landing site by generating a panoramic view of the surrounding terrain spanning full 360 degrees. It also provides fine-scale geological information of rock and soil attributes on the Martian terrain.
  • Color/composition: The multispectral capability of the camera helps in determining the soil mineralogy, the various weathering processes that could have affected the terrain and the determination of suitable target spots for further research.
  • Photometry: It helps in obtaining physical properties of the terrain such as grain size and roughness by exploiting the reflectance properties of rocks and soils by choosing appropriate incidence and emission angles.
  • Sun/Sky imaging: To monitor dust and cloud opacity.
