Shenzhou 6 was the second human spaceflight of the Chinese space program, launched on October 12, 2005, on a Long March 2F rocket from the Jiuquan Satellite Launch Center. The Shenzhou spacecraft carried a crew of Fèi Jùnlóng (费俊龙) and Niè Hǎishèng (聂海胜) for five days in low Earth orbit. It launched three days before the second anniversary of China's first human spaceflight, Shenzhou 5.
The crew were able to change out of their new lighter space suits, conduct scientific experiments, and enter the orbital module for the first time, giving them access to toilet facilities.
