China is working on prototypes of space rockets that will bring it closer to its long cherished dream of putting a man into space, the China Daily newspaper said on Thursday. A preliminary study on the rockets, aimed at stepping up China’s space program and international satellite services, has ended and efforts have shifted to the research and manufacturing of prototypes, it said. The new rockets, to be powered by liquid hydrogen, would bring the launch capacity of Chinese rockets closer in line with technology used elsewhere, it said. “The new rockets can be used to send large-scale astronomical telescopes and explorers to the moon and Mars,” the paper said.
