Curiosity Zaps Its First Martian Rock : Laser Spectroscopy Unlocks Red Planet Secrets
NASA’s Curiosity rover made history when it used its ChemCam laser to zap its first Martian rock, marking a breakthrough in planetary exploration. By firing a laser at the rock and analyzing the resulting plasma with laser-induced breakdown spectroscopy (LIBS), Curiosity revealed the elemental composition of the Martian surface without physical contact. This non-destructive technique allows scientists to identify rock types, detect chemical alterations, and search for signs of past water — all from millions of kilometers away. The successful use of LIBS on Mars not only showcases the power of remote spectroscopy but also opens new frontiers in the search for habitability on the Red Planet.
