Heavens watcher: The Yuanwang-6 represents a new generation of space-tracking ships designed and manufactured in the Mainland.

The Mainland's Yuanwang-6 space-tracking ship will arrive in Hong Kong on April 29 for a six-day visit.

Initiated by the Hong Kong Government, the visit kicks off a host of activities in the city to celebrate the 60th anniversary of the founding of the People's Republic of China.

Construction of Yuanwang-6 was completed in 2008. It represents a new generation of space-tracking ships designed and manufactured in the Mainland. On its maiden voyage last September, Yuanwang-6 was engaged in maritime tracking of the Shenzhou-7 manned space mission.
