SHANGHAI -- China will launch its first Mars probe in October 2009 as part of a joint mission with Russia, said sources with the Shanghai Space Administration, the main developer of the probe, on Monday. Researchers are "pressing ahead" with the project for a synchronized launching with a Russian probe, said Chen Changya, a researcher with the Shanghai Institute of Satellite Engineering, at a space technology exhibition. He said the home-developed Chinese probe is scheduled for completion by June 2009. The probe, 75 centimeters long, 75 centimeters wide, 60 centimeters high and weighing 110 kilograms, is designed to be able to serve a two-year mission, according to Chen. Its model is on display at the exhibition. The Chinese probe, with Russia's Phobos-Grunt, will be launched by a Russian carrier rocket, Chen said. They are expected to land on Mars in 2010 after 10 month's flight.

Yichang - Construction of a tunnel under the Yangtze River that will form part of a gas pipeline project running from Sichuan Province to Shanghai was completed Monday.The 1.4-km, 3.08-m diameter tunnel sits 20 m beneath the riverbed and connects two wells on either side of the river in Yichang city, Hubei Province, Liu Juzheng, head of the Hubei section of the pipeline, said.With a total length of 2,203 km, the pipeline will serve as an "energy artery" as part of the West-East gas project, Liu said.The pipeline is expected to channel 12.1 billion cu m of natural gas a year from the Puguang field in Sichuan to central and eastern regions of the country, including Chongqing Municipality, the provinces of Hubei, Anhui, Jiangxi, Jiangsu and Zhejiang, and Shanghai Municipality.The tunnel, which took 325 days to complete, is the first of five to be built under the Yangtze.Industry experts say the new pipeline, which will cost 62.7 billion yuan (.4 billion) to build, will provide an opportunity to develop western regions based on their rich natural resources.Chen Deming, vice-minister of the National Development and Reform Commission (NDRC), said the pipeline will be completed in late 2010 and the gas it transports will help reduce carbon dioxide emissions by tens of millions of tons a year.Figures from the China Petrochemical Corporation (Sinopec) put Puguang's proven reserves at 356.1 billion cu m. The country has total proven natural gas reserves of about 2.66 trillion cu m.The government has been promoting the use of natural gas to improve energy efficiency and reduce air pollution.Under an NDRC proposal on natural gas development, the government plans to increase the natural gas pipeline network to 44,000 km by 2010 to meet demand.Although China's natural gas output will reach 94 billion cu m in 2010, up from 58.6 billion in 2006, an additional 16 billion cu m a year will still have to be imported to meet demand, Sinopec said.In Shanghai, demand for natural gas soared from 4 million cu m in 2003 to 1.9 billion in 2005.In 2004, China National Petroleum Corp (CNPC) opened its West-East gas pipeline, which runs more than 4,000 km and channels 1.2 billion cu m of gas a year to Shanghai from the Tarim Basin in the country's westernmost region of Xinjiang.CNPC is to build a second West-East pipeline to carry gas imported from central Asia to the Pearl and Yangtze river deltas. Construction will begin next year with the line, which is designed to carry 30 billion cu m a year, becoming operational in 2010.

SHANGHAI: A revised rule that forces shipping companies to shoulder the cost of cleaning up pollution from maritime accidents, such as oil spills, in China's waters, is likely to take effect next year, if not sooner, a senior official with China Maritime Safety Administration (MSA) said Wednesday.If the revised regulation is approved by the State Council, companies such as Sinopec, PetroChina and the China National Offshore Oil Corp (CNOOC) will be required to contribute to a special compensation and clean-up fund, Liu Gongcheng, executive director of China MSA, said.Liu told a press conference prior to the 2007 Shanghai International Maritime Forum, which kicked off Wednesday, the fund will boost the country's emergency response capabilities to maritime pollution disasters.The official declined to say how big the fund could be.The rules also include a scheme asking all ships using its seawaters to purchase insurance.Liu said the mechanism, already in the pipeline for two years, is one of China MSA's measures to handle possible oil spill pollution, as the ocean environment faces greater pressure with increased shipping traffic, including oil cargo ships to and from China's coast.Figures showed more than 90 percent of China's oil imports - 145 million tons last year - is transported by sea. Some 163,000 tankers of all sizes sailed into and out of China's ports last year, an average of 446 every day."The size of oil tankers is also getting bigger, up to 300,000 tons, which has added to the risk," Liu said. "If only 1 percent of the oil is spilled, we will be confronted with a catastrophe."Oil spills can wreak havoc on sea life, fishing and tourism. They cost millions of yuan to clean up and even more in compensation and damages, he said.The oil spill from the tanker Prestige, which sank off Spain in November 2002, leaked 77,000 tons of oil that caused several billion dollars worth of damage.In the past year, there have been several oil spills in domestic seawaters that involved 500 to 600 tons of oil, but didn't cause serious pollution due to emergency response, Liu said.Losses caused by ships using international waters can be covered by insurance in accordance with international conventions.However China urgently needs a mechanism to cover the costs many small- and medium-sized ship owners cannot afford."It is not fair to let the clean-up companies shoulder the cost, so the compensation fund can be especially useful in that situation," he said.The administration is continuing to invest in facilities and enhance China's emergency response capabilities.

CHANGSHA -- China will spend 16.5 billion yuan to protect and restore its wetlands during the 11th five-year-plan period (2006-2010). Addressing a recent forum on the Yangtze River held in Changsha, the capital of Central China's Hunan Province, Zhu Lieke, deputy head of the State Forestry Administration, said China has made an inventory of 173 wetlands, most of which are in northeast China and the Yangtze River Valley. Thirty of the country's wetlands are listed in the international wetland catalogue, and one third of them are situated along the Yangtze. "Phenomena such as the rapid drop in the number of lakes and fast shrinkage in lake area got worse as China's economy tears through resources," said Zhu, who warned that wetlands in the Yangtze River Valley face uNPRecedented ecological threats. "The problems that plague wetlands in the Yangtze River Valley include pollution, ecological degradation and dwindling water resources," said Zhu. "The protection of our wetlands is urgent." The 6,300-km-long Yangtze, the country's longest, originates in the Tanggula Range on the Qinghai-Tibet Plateau and passes through Qinghai, Tibet, Sichuan, Yunnan, Chongqing, Hubei, Hunan, Jiangxi, Anhui, Jiangsu and Shanghai before emptying into the East China Sea. Wetlands in the Yangtze River Valley include salty plateau lakes and plateau marshlands, the galaxy of lakes on the middle reaches of the Yangtze, and the coastal wetland near Chongming Island at the estuary of the river. Dongting Lake, which flows into the Yangtze River and also serves as an important wetland, for instance, is shockingly polluted. Marine life has been decimated and people are catching a disease called schistosomiasis -- caught by swimming or wading in water where there are parasitic worms. The water area of Dongting Lake has shrunk from 4,350 sq km in 1949 to present 2,625 sq km as a result of silting and land reclamation for farming. According to Zhu, the country has already launched three programs to protect the wetlands in the Yangtze River Valley, including the national program for conservation of wildlife, plants and nature reserves, and the program to protect the Sanjiangyuan wetland in Qinghai Province. But much remains to be done.

China will undertake nearly 10 percent of an international fusion-research project to be implemented this year.The project is called ITER and wants to demonstrate the scientific and technical feasibility of fusion power - the energy of the sun or hydrogen bomb - for peaceful use."The project aims to find a shortcut to solve our energy shortage," Luo Delong, deputy director of the ITER China Office, said at the Oriental Science and Technology Forum held in Shanghai over the weekend.He said Chinese researchers will be in charge of producing various components of the project and escorting them into Cadarache in the south of France where the ITER's key equipment will be constructed.China will inject about one billion yuan (US7.5 million) into the project, accounting for nearly 10 percent of the overall ITER investment, officials said.Other partners in the project include the European Union, the United States, Japan, India and Russia.According to Zhang Jie, a fusion-power scientist of Jiao Tong University, researchers of universities in Shanghai, including Fudan and Donghua, are conducting fusion-related studies.China will further enhance its education in the area to lift the country's overall research power.The long-term objective of the research is to harness fusion nuclear energy to help meet the future energy needs of mankind, project officials said.The aim of ITER is to show fusion can be used to generate electrical power and do the preparation work to build and operate an electricity-producing plant.The key part of the project is to develop a viable fusion-power reactor.Scientists of ITER will test a number of key technologies, including the heating, control, diagnostic and remote maintenance that will be needed for a real fusion-power station, officials said.Local experts said fusion may produce dozens of times more energy than fission, which now directs most of the world's nuclear-power plants.Fission can only be caused by uranium. However, the resource to trigger fusion can be found in ordinary substances from the sea, they said.According to the Website of ITER, the overall construction cost of ITER is estimated at five billion euros (US.37 billion) over 10 years and another five billion euros are earmarked for the 20-year operation period.The ITER organization owns the ITER device and is responsible for all aspects of the project, such as licensing procedures, hardware procurements and operation.
