The ChemCam instrument is an international collaboration led by Los Alamos National Laboratory in the United States and the Institut de Recherche en Astrophysique et Planetologie in France.

ChemCam is on the Curiosity rover, exploring Gale Crater at Mars since 2012. It is used to perform rapid chemical and microscopic reconnaissance

Pulsed laser vaporizes targets up to 5 meters away. The spectrum of light from the laser-induced plasma reveals the chemical composition of the targets in seconds. ChemCam can detect most elements!

It also provides images of targets with high-resolution (can see a human hair 2 meters away).
