The 1-ton Curiosity rover has been exploring Gale crater on Mars since 2012. In its first year it discovered clay minerals that indicated the presence of a freshwater lake. The 20 km traverse has included a 300 meter climb through finely layered (mm) lacustrine strata, the vertical extent of which speaks to the longevity of the lake. Curiosity has discovered organic molecules as well as deposits of manganese oxides, which require a high oxidation potential for their deposition. Both Curiosity and its successor to be launched in 2020 carry laser remote-sensing instruments (ChemCam and SuperCam) pioneering the use of laser-induced breakdown spectroscopy (LIBS) technique in planetary science. I will highlight these instruments and how they are used to understand the Red Planet.
