Chinese lunar orbiter to begin observations - New Scientist Space

China's lunar orbiter is set to begin switching on its science instruments. The spacecraft should help determine the thickness of the lunar soil and shed new light on the Moon's internal composition, which could help in understanding its origins.

......

Like the other missions, Chang'e 1 has spectrometers to map the chemical composition of the Moon's surface, a laser altimeter to map the Moon's topography, and a camera to photograph the surface.

However it does have one unique instrument – a radiometer that operates at microwave frequencies. The microwave radiometer will measure heat radiation coming from the Moon. This will allow it to map the depth of the lunar soil across the Moon's surface because the layer's thickness affects the flow of heat.

Planetary scientist Carolyn Porco says, "I'm going to take you on a journey." And does she ever. Showing breathtaking images from the Cassini voyage to Saturn, she focuses on Saturn's intriguing largest moon, Titan,with deserts, mudflats and puzzling lakes, and on frozen Enceladus, which seems to shoot jets of ice.
