Diviner is a nine-channel radiometer that is largely identical to the Mars Climate Sounder (MCS) instrument on NASA's Mars Reconnaissance Orbiter (MRO). MCS was designed to map the three dimensional structure of temperature, dust, water ice and water vapor in the atmosphere of Mars, whereas Diviner has been designed to map the surface temperature of the Moon. This will be accomplished by using two identical boresighted telescopes to focus emitted and reflected radiation from the lunar surface onto uncooled thermopile detectors. Diviner's spectral channels are defined by interference and mesh filters that transmit specific portions of the visible and infrared spectrum. Diviner includes an articulated elevation / azimuth mount that allows it to point in virtually any direction.
