China's rocket man

Qian Xuesen is widely celebrated in China as the father of the country’s rocket programme, and the man who kick-started its exploration of space. China is now second only to the US in terms of its dominance among the stars. But Qian also had an important part to play in the early scientific advances, before World War Two, that would eventually take the US to the moon. However, he is almost entirely forgotten by the country that nurtured his talent for decades, before anti-communist persecution sent him back to China, the land of his birth. Kavita Puri traces the rise and fall - and rise again - of an extraordinary life.
