Beijing—（13, July） China 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 province．The new satellite will promote the country’s satellite munication network for space docking（对接）．
The satellite was launched on a Long-March-3C 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 munications 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, 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 mand the country’s space vehicles in low-Earth orbits, such as manned spacecraft and remote sensing satellites, from a higher position in outer space．Only three satellites of this kind are needed to form a global munication 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 munications, which will benefit the country’s future manned space flights, he said．

(答案→)D
解析：【小题1】D根据第一段最后一句The new satellite will promote the country’s satellite munication network for space docking（对接）．可知答案
【小题1】A根据最后一段第二句Only three satellites of this kind are needed to form a global munication network, and China has two now．”三颗卫星组成全球网络中国现在有两颗故还需一颗。
【小题1】C根据最后一段最后一句…which will benefit the country’s future manned space flights,可知这颗卫星对中国的空间探索意义重大。
【小题1】D根据本文开篇叙述可知新卫星发射有助于提升交流网络，文中又提及这可卫星的作用以及最后一段提到这颗卫星对中国的空间探索意义重大可知D选项作为本为标题合适。
