China poised to launch Tianzhou-3 cargo ship to replenish Tiangong space station

China is set to launch a third cargo spaceship to dock at its space station to deliver fresh supplies and bring back three astronauts who have been there for almost three months, sources say.

Two sources familiar with China’s manned space programme said the Tianzhou-3 cargo spaceship was scheduled to launch next Monday from the southern island of Hainan.
