Mössbauer Spectrometer (MB)
The Mössbauer Spectrometer sensor head is small enough to fit in the palm of your hand. It is one of four instruments mounted on the turret at the end of the rover arm. Its electronics are housed inside the body of the rover (in the Warm Electronics Box, or WEB). Measurements are taken by placing the instrument's sensor head directly against a rock or soil sample. One Mössbauer measurement takes about 12 hours.
