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.

Solidot | Brian May，从摇滚明星到天体物理学家
Brian May，是著名摇滚乐队Queen的吉他手(60岁)，完成了耽搁已久的天体物理学领域的博士论文，已正式向30年前就读的伦敦Imperial学院递交了论文，论文标题是”Radial Velocities in the Zodiacal Dust Cloud”。如果审核通过的话，还要等到明年他才能获得博士学位。1970年，Brian May在Imperial学院天体物理系读书时与主唱Freddie Mercury，鼓手Roger Taylor组成了Queen摇滚乐队，随着Queen的走红他放弃了星际尘埃方面的博士研究。
无缘诺奖再显中国科技软肋

2007年的诺贝尔奖正在陆续公布。与往年一样，这份名册中没有中国科学家的名字。从瑞典科学家诺贝尔1901年设立该奖项以来，至今共有771人获得此殊荣（不包括今年）。很遗憾，没有一位中国本土科学家获此殊荣。可是，每年的诺奖，总会触动中国人敏感的神经。
有人对中国人的这种“诺奖情节”不以为然。但是我依然以为，中国需要一次诺贝尔奖。理由很简单，占世界人口四分之一的中国，应该在科学领域有自己的声音。 Read More
