Area of Science:

  • Planetary Science
  • Astrogeology
  • Spectroscopy

Background:

  • The Mars 2020 Perseverance rover is equipped with the advanced SuperCam instrument suite for remote sensing.
  • SuperCam integrates multiple analytical techniques to study Martian surface composition and physical properties.

Purpose of the Study:

  • To describe the SuperCam instrument's body unit (BU) and the integrated system's testing.
  • To demonstrate the capabilities of SuperCam's diverse remote-sensing techniques for Mars exploration.

Main Methods:

  • The SuperCam instrument suite includes laser-induced breakdown spectroscopy (LIBS), Raman and luminescence spectroscopies, visible and infrared (VISIR) reflectance spectroscopy, a remote micro-imager (RMI), and a microphone.
  • The body unit (BU) receives optical input from the mast unit (MU) via an optical fiber, splitting light into UV, violet, and a high-efficiency transmission spectrometer for analysis.
  • Integrated instrument testing was performed, including the development of a LIBS standards library and demonstration of Raman, VISIR, luminescence, RMI, and microphone functionalities.

Main Results:

  • Testing validated the capabilities of LIBS, Raman, and VISIR spectroscopy for clear mineral identification.
  • Luminescence spectroscopy demonstrated utility in both spectral and temporal dimensions.
  • RMI and microphone subsystems showed effective performance for context imaging and environmental/physical property analysis.

Conclusions:

  • The integrated SuperCam instrument is fully functional and capable of performing its diverse remote-sensing analyses on Mars.
  • SuperCam's comprehensive suite of tools provides versatile capabilities for in-situ geological and environmental investigations on the Martian surface.
