Aerospace experts saved the country's first ever manned space mission as the spaceship faced a potentially lethal impact while flying through the communications blackout area before landing, the country's space authorities revealed yesterday.China became only the third country to put a man in space, after the former Soviet Union and the United States, when Yang Liwei orbited the Earth in 2003 in what was a resounding success for its space program.But Xinhua News Agency reported that this was almost not so, quoting the Xi'an Satellite Monitor and Control Center's report on the dangers the Shenzhou V rocket faced."Yang lost every means to communicate with the ground command and control headquarters as he entered the ( Earth atmosphere), which fell in the worst-case scenario prepared by the space mission team," Xinhua quoted Dong Deyi, head of the center, as saying.Communications go down when any spacecraft re-enters the Earth's atmosphere, but in Yang's case, "even radar could not capture any signal from the returning module", Dong was quoted as saying. "After the Shenzhou V came out of the blackout area, the echo signals from the spaceship were still volatile, which sufficiently threatened the safe landing of astronaut Yang."Mission control promptly ordered optical guiding and tracking instead of a communication-guided landing, Dong was quoted as saying."Aerospace technologists used cinetheodolites (optical trackers) on the ground to measure the spacecraft's position and record movements. Precise positioning of the spacecraft enabled officers to properly control the slow-down parachute, which was vital to a soft landing."But the landing was 9 km east of the planned site, Dong said.China began its clandestine manned space program in 1992. The country has since spent at least 20 billion yuan (.64 billion) on the project and sent three astronauts into orbit.Dong also revealed that at least three orbiting satellites were malfunctioning during certain periods, but all had been salvaged by experts since October 2006.The Xi'an center, established on June 23, 1967, in the mountains of Northwest China, has monitored and controlled more than 100 satellites and the six Shenzhou spaceships. According to official records, China now has at least 19 satellites orbiting the earth.China plans to chart every inch of the moon's surface as part of its ambitious space program.China, which plans to launch a lunar orbiter called "Chang'e I" in the second half of this year to take 3D images, would aim to land an unmanned vehicle on its surface by 2010, Zhang Yunchuan, minister of the commission of science, technology and industry for national defense, said on Friday.Xinhua-Agencies

Beijing - China is turning the site of a prison camp run by Japanese forces during World War Two into a war museum, the Xinhua news agency said on Sunday. More than 2,000 prisoners from the United States, Britain, the Netherlands and Australia were imprisoned at the camp in Shenyang, a Manchurian city formerly known as Mukden, between November 1942 and August 1945. More than one in 10 of them died, Xinhua said. Many Chinese believe Japan has yet to apologize properly for its invasion and occupation of China in the years leading up to and during the war. The 54 million yuan (US million) museum in Shenyang will include a two-storey brick building, three bungalows and a water tower, all original camp buildings in the Dadong district, Xinhua said. Two walls in a square will be inscribed with the names of the prisoners of war. China has a museum in Nanjing commemorating the slaughter of the citizens of that city, formerly known as Nanking, by invading Japanese troops 70 years ago. Nanjing has become the focal point for Japanese ultra-nationalists who dispute the Chinese estimate that 300,000 died or even that any massacre occurred. An Allied tribunal after the war put the death toll at about 142,000 men, women and children.

BEIJING -- Timothy Keating, US Pacific Command commander-in-chief, will visit China from January 13 to 16, the Chinese Ministry of National Defence (MND) said on Tuesday.During Keating's China stay, senior Chinese generals and officials from the Central Military Commission, the General Staff of the Chinese People's Liberation Army (PLA), Guangzhou Military Area Command and the Ministry of Foreign Affairs will meet him separately, the foreign affairs office of the MND said in a press release.The Chinese officials were expected to widely exchange views with Keating on Sino-US military ties, the Taiwan issue, and international and regional affairs of common concern, according to the press release.The four-day tour would also take Keating to the country's financial hub of Shanghai, and Guangzhou, capital of the southern Guangdong Province. There, he was scheduled to visit the PLA military institutions and bases and hold a seminar with Chinese military officials."China takes positive attitude toward developing military relations with the United States, and hopes Keating's visit could further enhance understanding, expand consensus and boost cooperation, so as to promote the bilateral military ties to grow steadily in the new year," the release said.The MND was consulting with the US side on detailing arrangements of the visit.Keating was visiting China for the second time since being appointed to the post in March. He was last here in May.

BEIJING - China's currency, the yuan, hit a new high against the US dollar on Thursday, following an overnight key interest rate cut in the United States.The yuan, also known as the renminbi, went up 145 basis points from the previous day to a central parity rate of 7.1853 yuan to one dollar, breaking the 7.19 mark.The Federal Reserve on Wednesday cut US interest rates by a bold half-percentage point as part of its efforts to shore up economic growth.The move came just eight days after the US central bank slashed rates by three quarters of a percentage point, leading the dollar to weaken against other major world currencies.The Chinese currency had appreciated against the greenback by about 12 percent since a new currency regime was imposed in July 2005 to revalue and de-peg it from the dollar.It had climbed 6.9 percent against the dollar in the past year, but some US critics say it remains undervalued, giving Chinese exporters an unfair advantage and resulting in the massive trade imbalance between the two countries.China was not against revaluation of the yuan, but opposed "excessively rapid" appreciation that was inappropriate to its national conditions, Commerce Minister Chen Deming said last month.Premier Wen Jiabao also said China would improve the yuan's exchange rate mechanism in a controllable and gradual manner, let the market play a bigger role in the mechanism and enhance the currency's flexibility.
