"China's first female astronaut in space … will be the 56th woman to fly into space out of the more than 500 people that have made it into orbit worldwide," said space history and artifacts expert Robert Pearlman, editor of collectSPACE.com, a SPACE.com partner site. "The first woman in space, Soviet cosmonaut Valentina Tereshkova was launched on June 16, 1963. If Shenzhou 9 launches on Saturday, it will be exactly 49 years to the day after Tereshkova's historic first flight."
