Jiuquan, China - China plans to launch its next crewed space mission on Tuesday.

The Shenzhou 16 spacecraft is scheduled to take off from the Jiuquan spaceport in north-west China at 9:31 AM for the now fully operational Tiangong (Heavenly Palace) space station, China's space agency announced on Monday.

The crew of the spacecraft consists of three taikonauts. Their mission in space is expected to last about five months.

The Tiangong space station underpins China's ambitions to become a space power and to catch up with the major space-faring nations: the United States and Russia.
