BEIJING, Oct. 13 (Xinhuanet) -- China is able to ensure a safe return of its second manned spacecraft Shenzhou-6 as it has reached the world level in recovery technologies, Hou Ying, chief designer of the manned spacecraft landing system, said Thursday.

    When China launched Shenzhou-1, an unmanned spacecraft, in 1991,there was only one landing field, and an emergency landing ground was added for Shenzhou-2 ten years later.
