China will send its first woman and two other astronauts into space Saturday to work on a temporary space station for about a week, in a key step toward becoming only the 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 213 miles above the Earth.
