US physicist pleads guilty to supplying US space program secrets to China.

"Shu Quan-Sheng, a Chinese-born naturalized US citizen and physicist who headed a high-tech company, is facing a 10-year prison sentence for having sent secret information about the US space program to China from 2003 to 2007.

China sent its first man into space in 2003, followed by a two-man mission in 2005.

The charges against Shu arise out of a probe led by the Federal Bureau of Investigation with US trade and customs officials."
