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.

   A new study warns that about thirty percent of the world’S people may not have enough  water by the year 2025.

    P—A—I researcher Robert Engelman says by the year 2025,about 3,000 million people may lack water.At least 18 more countries are expected to have severe water problems.The

demand for water keeps increasing.Yet the amount of water on Earth stays the same.

   The Population Action International study gives several solutions to the water problem.One way,it says,is to find ways to use water for more than one purpose.Another way is to teach people to be careful not to waste water.A third way is to use less water of agriculture.

  The report also says long--term solutions to the water problem must include controls on population growth.It says countries cannot provide clean water unless they slow population growth by limiting the number of children people have.
