thumb Chemistry and Camera complex (ChemCam) is a suite of remote sensing instruments on Mars for the ''Curiosity'' rover. As the name implies, ChemCam is actually two different instruments combined as one: a laser-induced breakdown spectroscopy (LIBS) and a Remote Micro Imager (RMI) telescope. The purpose of the LIBS instrument is to provide elemental compositions of rock and soil, while the RMI will give ChemCam scientists high-resolution images of the sampling areas of the rocks and soil that LIBS targets.〔(【引用サイトリンク】title=MSL Science Corner: Chemistry & Camera (ChemCam) )〕 The LIBS instrument can target a rock or soil sample from up to away, vaporizing a small amount of it with about 50 to 75 5-nanosecond pulses from a 1067 nm infrared laser and then observing the spectrum of the light emitted by the vaporized rock. ChemCam has the ability to record up to 6,144 different wavelengths of ultraviolet, visible, and infrared light.〔(【引用サイトリンク】title=Rover's Laser Instrument Zaps First Martian Rock. )〕 Detection of the ball of luminous plasma will be done in the visible, near-UV and near-infrared ranges, between 240 nm and 800 nm.〔 The first initial laser testing of the ChemCam by ''Curiosity'' on Mars was performed on a rock, N165 ("Coronation" rock), near Bradbury Landing on August 19, 2012. The ChemCam team expects to take approximately one dozen compositional measurements of rocks per day. Using the same collection optics, the RMI provides context images of the LIBS analysis spots. The RMI resolves objects at distance, and has a field of view covering at that distance.〔 The ChemCam instrument suite was developed by the Los Alamos National Laboratory and the French CESR laboratory.〔 The flight model of the mast unit was delivered from the French CNES to Los Alamos National Laboratory.〔(ChemCam Status April, 2008 ).
