This image shows the calibration target for the Chemistry and Camera (ChemCam) instrument on NASA's Curiosity rover. The calibration target is one square and a group of nine circles that look dark in the black-and-white image.
This is the first laser spectrum from the ChemCam instrument on NASA's Curiosity rover, sent back from Mars on Aug. 19, 2012, showing emission lines from different elements present in the target, a rock near the rover's landing site dubbed 'Coronation.'
Mars Rock 'Rocknest 3' Imaged by Curiosity's ChemCam
This view of a rock called 'Rocknest 3' combines two images taken by the Chemistry and Camera (ChemCam) instrument on the NASA Mars rover Curiosity and indicates five spots where ChemCam had hit the rock with laser pulses to check its composition.
The shape of the tip of the bit in the drill of NASA's Mars rover Curiosity is apparent in this view recorded by the remote micro-imager in the rover's ChemCam instrument on Mars. Jan. 29, 2012; the bit is about 0.6 inch (1.6 centimeters) wide.
The Chemistry and Camera (ChemCam) instrument on NASA's Mars rover Curiosity used its laser to examine side-by-side points in a target patch of soil, leaving the marks apparent in this before-and-after comparison.
This pair of images taken a few minutes apart show how laser firing by NASA's Mars rover Curiosity removes dust from the surface of a rock. The images were taken by the remote micro-imager camera in the laser-firing Chemistry and Camera (ChemCam).
Drill Bit Tip on Mars Rover Curiosity, Head-on View
This head-on view shows the tip of the drill bit on NASA's Mars rover Curiosity. The view merges two exposures taken by the remote micro-imager in the rover's ChemCam instrument at different focus settings.
Laser Hit on Martian Sand Target, Before and After
The Chemistry and Camera (ChemCam) instrument on NASA's Mars rover Curiosity used its laser and spectrometers to examine what chemical elements are in a drift of Martian sand during the mission's 74th Martian day, or sol (Oct. 20, 2012).
This mosaic shows the calibration target for the Chemistry and Camera (ChemCam) instrument on NASA's Curiosity rover, as seen by the ChemCam's remote micro-imager. The 10 images incorporated in this mosaic were taken on Aug. 15.
Curiosity's ChemCam Analyzes Rocks, Soils and Dust
This diagram shows how materials analyzed by the ChemCam instrument on NASA's Curiosity Mars rover during the first 100 Martian days of the mission differed with regard to hydrogen content (horizontal axis) and alkali (vertical axis).
The ChemCam instrument on NASA's Curiosity Mars rover fired its laser 50 times at its onboard graphite target showing spectral measurements from the first shot, which hit dust on the target, compared to spectral measurements of from the 50th shot.
A conventional X-ray diffraction instrument (left) is the size of a large refrigerator, in contrast to the compact size of the Chemistry and Mineralogy (CheMin) instrument on NASA's Curiosity rover (top right).
This image illustrates the principals of a technique called 'laser-induced breakdown spectroscopy,' which the Chemistry and Camera (ChemCam) instrument onboard NASA's rover, Curiosity, will use on Mars.
This charged couple device (CCD) is part of the CheMin instrument on NASA's Curiosity rover. When CheMin directs X-rays at a sample of soil, this imager, which is the size of a postage stamp, detects both the position and energy of each X-ray photon.
