This is the second crewed mission for China's Shenzhou program. Shenzhou-6 began its mission by carrying astronauts Fei Junlong and Nie Haisheng into low Earth orbit. During their mission, astronauts conducted scientific experiments, which mainly had to do with how human body responds to spaceflight. After almost 5 days in orbit Shenzhou-6 deorbited and landed back safely on Earth on 16 October.
