"The first microwave image of the complete Moon was obtained thanks to the Chinese lunar satellite Chang'E-1. Global brightness temperature maps reveal radiation from the surface and deeper layers of the Moon and its diurnal variation. This will help astronomers to determine the detailed heat flow and, thus, the inner energy of the Moon."

The first microwave image of the complete Moon was obtained thanks to the Chinese lunar satellite Chang'E-1. Global brightness temperature maps reveal radiation from the surface and deeper layers of the Moon and its diurnal variation. This will help astronomers to determine the detailed heat flow and, thus, the inner energy of the Moon.

These exciting new results are being presented by Dr. Yong-Chun Zheng and Dr. Kwing L. Chan at the European Planetary Science Congress in Rome.

Chang'E-1 (CE-1) is China's first scientific mission to explore planetary bodies beyond Earth. The stereo camera, one of the eight science instruments on board the spacecraft, has produced a state-of the-art global image of the Moon with unprecedented image quality and positioning precision. The Solar Wind Ion Detector (SWID) has discovered the acceleration of scattered solar wind protons close to the lunar polar terminator. And now, the Lunar Microwave Radiometer (MRM) made it possible, for the first time, to globally map the Moon in microwave frequencies.…
