Quote:

"American and Russian aerospace engineers perfected space docking in the 1960s, but Wu Ping, a spokeswoman for China’s manned space program, said that Chinese scientists had come to this moment largely on their own

There is in place a "20-year-old sanctions that limit cooperation between American and Chinese aeronautical engineers  * * * The policy, imposed by Congress shortly after Beijing’s violent suppression of pro-democracy protesters in 1989, restricts scientific exchanges and blocks exports of space technology. Chinese scientists are barred from American space conferences, and China is not among the 16 countries whose astronauts are allowed to use the International Space Station.

Quote:

"When he heard that NASA had no plan to send astronauts to Mars, it boggled his mind. The financial problem seemed straightfoward, if not simple: Existing rockets employed old technology, used once. 'Imagine,' he says, 'if you built a new 747 for every flight.'

"And if he can figure out how to recover the first stage of his F9 [rocket], he'll have done no one has ever done before--created a fully reusable rocket which costs only $200,000 per flight for propellant. * * * 'And I think I have.'
