China Grabbing More Satellite Launch Business

China has a well-developed range of Long March rockets for use in commercial launches, all of which now mainly burn liquid fuel that must be pumped in just prior to launch. Solid fuel rockets can be kept in storage, then fired when needed, making them ideal for military use in launching ballistic missiles.

Liquid-fueled rockets are generally considered best-suited for launching large payloads, while solid rockets are used for placing smaller satellites weighing less than 2 tons into low Earth orbit.

“The development of the Long March 11 will greatly improve China’s capabilities to rapidly enter space and meet the emergency launching demand in case of disasters and emergencies,” Liang was quoted by Xinhua as saying.

On Friday, China’s space program said it would send three astronauts to its orbiting space station this summer as part of preparations to establish an even larger permanent presence above Earth.

The Shenzhou 10 spacecraft, which will likely include one female astronaut, will spend two weeks aboard the Tiangong 1, where the trio will spend two weeks conducting tests of the station’s docking system and its systems for supporting life and carrying out scientific work.

Two Chinese spacecraft, one of them manned, have docked already with Tiangong 1 since it was launched in September 2011.

The station is to be replaced in around 2020 with a permanent space station that will weigh about 60 tons, slightly smaller than NASA’s Skylab of the 1970s and about one-sixth the size of the 16-nation International Space Station.
