Beijing—13, JulyChina sent up a new data relay satellite(数据中继卫星), Tianlian I-02, on Monday at the Xichang Satellite Launch Centre in South-western Sichuan provinceThe new satellite will promote the country's satellite communication network for space docking(对接).

The satellite was launched on a Long-March-3C carrier rocket at 11:41 pm, sources at the centre told Xinhua News AgencyThe satellite separated from the rocket 26 minutes after its launch and was then successfully delivered into a geostationary transfer orbit (地球同步转移轨道).

Developed by the China Academy of Space Technology under the China Aerospace Science and Technology Corporation, the satellite is the country's second data relay satelliteThe first, Tianlian I-01, was launched on April 252008

The two satellites will form a network to improve communications between China's spacecraft and bases on Earth, according to the centreThey will also be used to help the nation's first space docking, scheduled for the second half of this year

As planned, China will launch space module Tiangong-I, which was designed as a platform that will dock with an unmanned spaceship, Shenzhou, for the county's first space-docking mission this year

Two more Shenzhou spaceships will dock with Tiangong-I next year, and one will be manned by two or three astronauts, according to China Manned Space Engineering Office, which was the main user of the Tianlian I series data relay satellites

“The new satellite can cover a greater area to track and command the country’s space vehicles in low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position in outer spaceOnly three satellites of this kind are needed to form a global communication network, and China has two now” Pang Zhihao, a researcher and deputy editor-in-chief of Space International, said

The satellite could also equip astronauts with real-time communications, which will benefit the country's future manned space flights, he said
