China is working on a super-powerful rocket that would be capable of delivering heavier payloads into low orbit than NASA, a leading Chinese space expert was quoted as saying Monday. By 2030, the Long March-9 rocket under development will be able to carry 140 tons into low-Earth orbit — where TV and earth observation satellites currently fly — said Long Lehao, a senior official from the Chinese Academy of Engineering, according to the official Xinhua news agency. — AFP
