“I want to extend my sincere thanks and congratulations to our international partners at CNES and the SuperCam team for being a part of this momentous journey with us,” said Thomas Zurbuchen, associate administrator for science at NASA Headquarters in Washington. “SuperCam truly gives our rover eyes to see promising rock samples and ears to hear what it sounds like when the lasers strike them. This information will be essential when determining which samples to cache and ultimately return to Earth through our groundbreaking Mars Sample Return Campaign, which will be one of the most ambitious feats ever undertaken by humanity.”
The SuperCam team also received excellent first datasets from the instrument’s visible and infrared (VISIR) sensor as well as its Raman spectrometer. VISIR collects light reflected from the Sun to study the mineral content of rocks and sediments. This technique complements the Raman spectrometer, which uses a green laser beam to excite the chemical bonds in a sample to produce a signal depending on what elements are bonded together, in turn providing insights into a rock’s mineral composition.
“This is the first time an instrument has used Raman spectroscopy anywhere other than on Earth!” said Olivier Beyssac, CNRS research director at the Institut de Minéralogie, de Physique des Matériaux et de Cosmochimie in Paris. “Raman spectroscopy is going to play a crucial role in characterizing minerals to gain deeper insight into the geological conditions under which they formed and to detect potential organic and mineral molecules that might have been formed by living organisms.”
More About the Mission
SuperCam is led by Los Alamos National Laboratory in New Mexico, where the instrument's Body Unit was developed. That part of the instrument includes several spectrometers, control electronics and software.
The Mast Unit was developed and built by several laboratories of the CNRS (French National Centre for Scientific Research) and French universities under the contracting authority of CNES. Calibration targets on the rover deck are provided by Spain’s University of Valladolid.
A key objective for Perseverance’s mission on Mars is astrobiology, including the search for signs of ancient microbial life. The rover will characterize the planet’s geology and past climate, pave the way for human exploration of the Red Planet, and be the first mission to collect and cache Martian rock and regolith (broken rock and dust).
Subsequent NASA missions, in cooperation with ESA (European Space Agency), would send spacecraft to Mars to collect these sealed samples from the surface and return them to Earth for in-depth analysis.
The Mars 2020 Perseverance mission is part of NASA’s Moon to Mars exploration approach, which includes Artemis missions to the Moon that will help prepare for human exploration of the Red Planet.
JPL, which is managed for NASA by Caltech in Pasadena, California, built and manages operations of the Perseverance rover.
