The NASA Curiosity rover exploring Mars carries a number of scientific instruments, including a spectrograph (a device for recording a spectrum), and a high intensity laser. On several occasions, Curiosity has fired its laser at the surface of a rock sample, while observing the process with a spectroscope. The laser is intense enough to vaporize the atoms on the surface of the sample into a hot, excited gas.
