Beijing ?(13, July) China sent up a new data relays atellite (数据中继卫星), Tianlian I -02, on Monday at the Xichang Satellite Launch Centre in South-western Sichuan province.The new satellite will promote the country's satellite communication network for space docking (对接).
The satellite was launched on a Long-March-SC carrier rocket at 11:41 p.m., sources at the centre told Xinhua News Agency.The 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 satellite.The first, Tianlian I -01, was launched on April 25.2008.
The two satellites will form a network to improve communications between China's spacecraft and bases on Earth, according to the centre.They 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 (天宫1号), 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 m low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position m outer space.Only 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 county s future manned space flights, he said.

YUZHOU, HENAN –An accident in a central China coal mine killed 21 miners Saturday and left another 16 trapped underground , the government said.
The death toll rose to 26 Sunday morning as rescuers were battling to reach the 11 miners who were still trapped underground, rescue headquarters said.
Rescuers were battling to reach the 11 miners still trapped underground, but chances for them to survive were very slim, said Du Bo, deputy chief of the rescue headquarters.
"Based upon past experience, the remaining 11 miners could be buried in coal dust, so the survival chances are frail," Du said.
More than 2,500 tons of coal dust smothered(厚厚的覆盖) the pit after the gas leak(漏出), which hampered(阻碍) the rescue, said Du.
The gas outburst happened at 6:03 a.m. Saturday when 276 miners were working underground in the mine in Yuzhou City. A total of 239 workers escaped but 21 were found dead and 16 trapped.
An initial(最初的) investigation showed that 173,500 cubic meters of gas leaked out in the accident. Liu Wenbin, a deputy chief engineer of the company that owns the mine, was in the pit(矿井) when the accident happened. He organized the escape.
"At around 6 a.m., I felt there was something wrong with the airflow in the shaft, and one of the team captains told me he also felt it and had already reported the problem," said Liu
The mine is owned by Pingyu Coal & Electric Co. Ltd., a company jointly established by four investors, including Zhong Ping Energy Chemical Group and China Power Investment Corp.
