Gamma Ray Spectrometer (2001 Mars Odyssey) power. Along with its cooler, it measures . The detector is a photodiode made of a germanium crystal, reverse biased to about 3 kilovolts, mounted at the end of a boom to minimize interferences from the gamma radiation produced by the spacecraft itself. Its spatial resolution is about . The neutron spectrometer is . The high-energy neutron detector measures . The instrument's central electronics box is .
