From British daily The Morning Star:
Father of space programme dies
Qian Xuesen, the father of China’s space technology programme, died on Saturday in Beijing. He was 98.
Mr Qian began his career in the US and was regarded as one of the brightest minds in the new field of aeronautics before returning to China in 1955, hounded out of the United States for his alleged membership of the CPUSA.
He went on to establish China’s first missile and rocket research institute which later helped start China’s space programme, led the development of China’s first nuclear-armed ballistic missiles and worked on its first satellite, Red East 1, which was launched in 1970.
A mysterious slowing of NASA’s Pioneer 10 and 11 spacecraft turns out to be due to the slight, but detectable effect of heat pushing back on the spacecraft, according to new research: here.
