Roger Wiens is a planetary scientist and Fellow at ‪@LosAlamosNationalLab‬. He is the principal investigator for both the ChemCam instrument aboard the Mars Curiosity rover and the SuperCam instrument, aboard the Perseverance rover. The SuperCam on NASA's Perseverance rover examines rocks and soils with a camera, laser and spectrometers to seek organic compounds that could be related to past life on Mars. It can identify the chemical and mineral makeup of targets as small as a pencil point from a distance of more than 20 feet (7 meters)
