Curiosity – Science from ChemCam

Earlier this week, Curiosity used its Chemistry and Camera (ChemCam) to record the ultraviolet (UV), violet, visible and near-infrared spectra from a rock called Coronation. The rock was bombarded with 30 laser pulses, and the light recorded by three spectrometers.

Viewing the enlarged image, minor elements titanium and manganese show in the insert on the left in the 398-to-404-nanometer range, and Hydrogen shows up in the right hand insert with carbon (from carbon dioxide in the Martian atmosphere). Hydrogen was only present in the first laser shot, indicating it was present only in the surface material.

The preliminary analysis shows the rock to probably be basalt, a common volcanic rock on Mars. Coronation is about 8 centimeters across and was located about 1.5 meters from Curiosity (prior to its drive yesterday).
