China's Shenzhou-11 spaceship, set to take two astronauts into space, was delivered to the Jiuquan Satellite Launch Center in northwest China on Saturday.

General assembly and testing will begin at the center ahead of its launch scheduled for mid-October, said a statement by China's manned space engineering office.

The spaceship will transport personnel and supplies to China's second orbiting space lab Tiangong-2, which is to be launched in mid-September.

The astronauts selected for the mission are both male and have been taking intense training, the statement said.

Tiangong-2, which will allow two astronauts to live in space for up to 30 days, was delivered to the center in early July and the carrier rockets arrived last week.
