Gu Chaohao, a mathematician, and space scientist Sun Jiadong won China's 2009 State Top Scientific and Technological Award.

Gu Chaohao was born in 1926 in Wenzhou of southeast Zhejiang Province. He received his doctorate in physics and mathematics from Moscow State University in 1959 and is a former vice president of Fudan University and a former president of University of Science and Technology of China.

He was honored for his "important contributions" to differential geometry, partial differential equations and mathematical physics, three sub-disciplines of modern mathematics, according to a statement from the awards organizing committee.

His pioneering research on partial differential equations contributed to solving mathematical problems in the field of supersonic aerodynamics and provided important methodology for later study of the discipline, said the statement.

Sun Jiadong was born in 1929 in Fuxian, of northeast Liaoning Province. He graduated from Zhukovsky Air Force Engineering Academy in the Soviet Union in 1958. He played a leading role in the design of the first Chinese satellite, Dong Fanghong I launched in 1970, the first recoverable remote-sensing satellite in 1975, the first geostationary communication satellite in 1984 and China's lunar exploration program.

Sun was recognized for his 50-year contribution to China's space industry and continuing service on the frontline of China's space technology.

The two scientists were each awarded 5 million yuan (732,300 U.S. dollars). Chinese President Hu Jintao presented them with the certificates at the Great Hall of the People in downtown Beijing.

China's lunar exploration program and two other scientific programs received a State Special Award for Scientific and Technological Progress.

The editing and research for the Flora of China won the first prize in the State Natural Science Award.

Twenty seven projects received second prizes in State Natural Science Award.
