China will send its first woman into space Saturday along with two other astronauts to work on a temporary space station for about a week, in a key step toward becoming the only third nation to set up a permanent base in orbit.
Liu Yang, a 34-year-old air force pilot, and two male colleagues will be launched Saturday aboard the Shenzhou 9 spacecraft, which will dock with the bus-sized Tiangong 1 space module now orbiting at 343 kilometers (213 miles) above the Earth.
Two of the astronauts will live and work inside the module to test its life-support systems while the third will remain in the capsule to deal with any unexpected emergencies. Wu said the mission will last more than 10 days before the astronauts travel back to Earth in the capsule, landing on Western Chinese grasslands with the help of parachutes.
The rocket began fueling Friday at the Jiugquan Satellite Launch Center on the edge of the Gobi desert in northern China, Wu told reporters at the center. The launch is scheduled for 6:37 p.m. (1237 GMT) Saturday, she said.
Joining Liu, a major, is veteran astronaut and mission commander Jing Haipeng and newcomer Liu Wang, both air force senior colonels.
Success in docking _ and in living and working aboard the Tiangong 1 _ would smooth the way for more ambitious projects, including the creation of a permanent space station and missions to the moon, and add to China’s international prestige in line with its growing economic prowess.
China is hoping to join the United States and Russia as the only countries to have sent independently maintained space stations into orbit. It already is in the exclusive three-nation club to have launched a spacecraft with astronauts on its own.
The mission demonstrates China’s commitment to “long-term human spaceflight” and marks a test of “the technological capabilities requisite for a future permanent space station,” said Joan Johnson-Freese, an expert on the Chinese space program at the U.S. Naval War College in Rhode Island.
Still, that is some years away. The Tiangong 1 is only a prototype, and the plan is to replace it with a permanent _ and bigger _ space station due for completion around 2020.
The permanent station 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.
Analysts say China’s exclusion from the ISS, largely on objections from the United States, was one of the key spurs for it to pursue an independent program 20 years ago, which reaches a high point with Saturday’s launch.
The three astronauts will perform medicals tests on the effect of weightlessness on the human body, as well as other scientific and engineering tasks on Tiangong, or Heavenly Palace, which was put into orbit in September.
Wu said the capsule would first dock by remote control, then later separate and dock again manually, to prepare the technology for a permanent space station.
China first launched a man into space in 2003 followed by a two-man mission in 2005 and a three-man trip in 2008 that featured China’s first space walk.
In November 2011, the unmanned Shenzhou 8 successfully docked with the Tiangong 1 by remote control _ twice to show the durability of the system.
While operating with limited resources, China’s space program is a source of huge national pride and enjoys top-level political and military backing. This has left it largely immune from the budgetary pressures affecting NASA, although China doesn’t say what it spends on the program.
The selection of the first female astronaut is giving the program an additional publicity boost. State media have gushed this week about Liu, pointing out that she once successfully landed her plane after a bird strike disabled one of its engines.
Shortly after Wu’s news conference, reporters were driven to a second building for a question and answer session with the astronauts, who were dressed in blue jump suits and seated behind a glass partition.
