The installation of key parts for China's second manned spaceship, the Shenzhou-6, has concluded in Shanghai.

Now the engineers are busy testing the spaceship's power and propulsion systems. If everything goes as planned, Shenzhou-6 will take off sometime in Autumn this year, carrying two astronauts on a 5-day mission.

Experts say the environment monitoring and life-support systems of Shenzhou-6 will face even bigger challenges than its predecessor.
