Listen here, little green men. No Martian bacteria are going to save you from Curiosity.
Forthwith flashes of actual flame, a bright glare leaping from one to another, sprang from the scattered group of men. It was as if some invisible jet impinged upon them and flashed into white flame. It was as if each man were suddenly and momentarily turned to fire...
... a man fell headlong and lay still; and as the unseen shaft of heat passed over them, pine trees burst into fire, and every dry furze bush became with one dull thud a mass of flames. And far away towards Knaphill I saw the flashes of trees and hedges and wooden buildings suddenly set alight.

The Curiosity Mars rover fires its death-ray ChemCam laser at a rock outcrop turning the landscape into molten rivers of terror
The Curiosity rover successfully test fired a powerful laser at a nearby rock Sunday, blasting it with rapid-fire million-watt pulses that vaporized the outer layers for spectroscopic analysis.
A rock near the Curiosity rover, dubbed "Coronation," was the first target for the mobile science lab's ChemCam laser. The laser beam vaporized a tiny area of the rock, creating a visible plasma that was telescopically studied by the instrument's three spectrometers to determine its composition.
