Martian Laser Surpasses 100,000 Zaps
The ChemCam laser instrument aboard NASA’s Curiosity rover fired its 100,000th shot recently, chronicling its adventures on Mars with a coffee-table-book’s worth of spectral data that might rival snapshots gathered during a long and satisfying family vacation here on Earth. ChemCam zaps rocks with a high-powered laser to determine their composition and carries a camera that can survey the Martian landscape.
“ChemCam has greatly exceeded our expectations,” said Roger Wiens, Los Alamos National Laboratory planetary scientist and Principal Investigator of the ChemCam Team. “The information we’ve gleaned from the instrument will continue to enhance our understanding of the Red Planet, and will nicely complement information from the other nine instruments aboard Curiosity as we continue our odyssey to Mount Sharp.”
