XI'AN, Sept. 18 (Xinhua) -- At least 12 people were killed and 22 others missing over the weekend in rain-triggered landslides in northwestern Shaanxi Province, local officials said.As of 5:30 p.m. Sunday, rescuers had retrieved 10 bodies from beneath the rocks and mud in Baqiao District of the provincial capital of Xi'an, while another five were injured, said Zhu Zhisheng, vice mayor of Xi'an, who was at the site.Another 22 people remained missing, Zhu said, adding the injured were hospitalized and in stable condition.The landslide around 2 p.m. Saturday unleashed about 100,000 cubic meters of rock and mud down the mountain, engulfing a brick factory and destroying part of a nearby ceramics factory in the suburban district of Xi'an.Rescuers found four bodies on Saturday night and six others were retrieved on Sunday.More than 700 police, firefighters and local residents joined the rescue which went on Sunday night.However, the rescue was hampered by three ensuing slides between 10 a.m. and 11 a.m. Sunday as heavy rains continued slashing the city.About 10,000 cubic meters of newly-triggered rock and mud roared down to the site, forcing rescuers to suspend searching temporarily.Heavy downpours in the province also caused havoc in other areas.A heavy rainfall on Saturday night triggered a landslide that buried a residential house in the suburban district of Jintai in Baoji City, some 175 km to the west of Xi'an.Two people were dug out but later died after they were rushed to a nearby hospital, the municipal government of Baoji said in a statement Sunday.The downpours also brought a landslide in the same district early Sunday morning. Three people were saved and sent to a local hospital, according to the statement.The three wounded were in stable condition, doctors at the hospital said.

BEIJING, Aug. 30 (Xinhua) -- China's second moon orbiter, the Chang'e-2, has arrived in outer space about 1.5 million km away from Earth and is now orbiting the second Lagrange Point (L2), where gravity from the sun and Earth balances the orbital motion of a satellite, Chinese scientists said Tuesday.Chang'e-2 entered L2's orbit at 11:27 p.m. last Thursday after spending 77 days traveling away from its previous orbital path around the moon, according to the State Administration of Science, Technology and Industry for National Defence (SASTIND).The SASTIND said that China is now the world's third country or organization to successfully put a spacecraft into orbit around L2, after the European Space Agency (ESA) and the National Aeronautics and Space Administration (NASA) of the United States.The Chang'e-2 orbiter will carry out exploration activities around L2 in the coming year, SASTIND said.There are five so-called "Lagrange Points" about 1.5 million km way from the Earth in the exact opposite direction from the sun. Putting a spacecraft at any of these points allows it to stay in a fixed position relative to the Earth and sun with a minimal amount of energy needed for course correction.The orbiter completed all of its assigned tasks after blasting off on Oct. 1, 2010, according to the SASTIND. Although the orbiter was only supposed to remain in space for six months, the SASTIND decided to assign additional tasks to it, as it still had fuel in its reserve tanks.Traveling into outer space from the moon's orbit was one of the orbiter's most important missions, according to the SASTIND.Before arriving at its current position in outer space, the Chang'e-2 took photos of the northern and southern poles of the moon. It then descended to a lower orbit, approximately 15 km away from the moon's surface, where it captured high-resolution images of the Sinus Iridum, or "Bay of Rainbows," an area where future moon probes may land.The SASTIND is reportedly planning to launch measure and control stations into outer space by the end of the second half of next year. The Chang'e-2 will be used to test the two stations' functionality at that time.China's ambitious three-stage moon mission will include a moon landing, as well as the launch of a moon rover during the second stage, which is scheduled to take place in 2012. During the third phase, another rover will land on the moon and return to Earth with lunar soil and stone samples for scientific research around 2017.China does not currently have a timetable in place for a manned moon landing. It launched its first lunar probe, the Chang'e-1, in October 2007.In 2003, China became the third country after Russia and the United States to send a human into space. Two more manned space missions followed, the most recent of which took place in 2008.0 The Chang'e probes are named after the Chinese legendary goddess of the moon.

BEIJING, Sept. 2 (Xinhuanet) -- The amount of space junk orbiting the Earth could cause fatal leaks in spaceships or destroy valuable satellites, according to a report released by the U.S. National Research Council.Computer models have shown that the number of orbital debris "has reached a tipping point, with enough currently in orbit to continually collide and create even more debris, raising the risk of spacecraft failures," the Research Council said Thursday.So far, there are 22,000 pieces of debris large enough to track from the ground, but smaller objects could still cause serious damage.New international regulations are needed to limit space junk.And more researches should be done to test the possible use of launching magnetic nets or giant umbrellas to push the debris further towards the Earth where it would burn up, or into a higher but safer orbit.

JIANGYIN, Jiangsu, July 1 (Xinhua) -- China's manned deep-diving submersible, the Jiaolong, embarked on a journey on Friday during which it will make a 5,000-meter dive in the Pacific Ocean.During the dive, the submersible will undergo several operational tests in which it will take photos, shoot video, survey seabeds and take samples from the ocean floor, according to Jin Jiancai, deputy director of the submersible's diving test program team.The tests will be conducted in the Pacific Ocean in accordance with a contract signed between the China Ocean Mineral Resources Research & Development Association and the International Seabed Authority (ISA).The submersible is scheduled to spend 47 days at sea, according to a statement from the Ministry of Science and Technology.A submersible differs from a submarine, as it typically depends on another vessel or facility for support.The Jiaolong, designed to reach a depth of 7,000 meters, completed 17 dives in the South China Sea between May 31 and July 18 last year, reaching 3,759 meters during its deepest dive.In the year since the submersible's last dive, program team members have made several technical improvements to the submersible and its support vessel, Jin said.Jin said the program team members are "very confident" about the test.He also stressed that the test will be carried out in accordance with the provisions of the United Nations Convention on the Law of the Sea as well as the ISA's rules and regulations.The Jiaolong is the world's first manned submersible designed to reach depths of 7,000 meters below sea level, according to Xu Qinan, the submersible's chief designer.

CANBERRA, Sept. 9 (Xinhua) -- Australia on Friday launched the first national study to find out whether low to moderate levels of alcohol drank by pregnant women are harmful or not to an unborn child, hoping to provide a clear indication about the safe amount of alcohol for pregnant women.The Murdoch Children's Research Institute in Melbourne, which commissioned the study, is recruiting 2000 pregnant women who will be quizzed throughout their pregnancy about their drinking habits, general health and diets.Their babies will then undergo medical checks, when they turn one and again at two to see if their brains, development and behavior was affected by alcohol consumed by their mums.According to lead researcher associate professor, Jane Halliday, while there was solid evidence about the dangers of heavy drinking for an unborn baby, it was not known if there was a safe amount of alcohol pregnant women could drink.She said the study hoped to shed light on the best approach to alcohol use during pregnancy."The problem is that for about half of women that get pregnant it is unplanned, and a lot of women are drinking around the time they get pregnant and may drink for the first month or so and that creates a lot of anxiety," Assoc Prof Halliday said in a statement."From the few international and Australian studies there's conflicting evidence as to whether there's an adverse effect."We firmly believe that no drinking is the safest option, but our main aim is to provide an evidence base to the policy and answer questions about individual risks."The study came after research by the University of Newcastle published in 2010 revealed 80 percent of Australian women drank during pregnancy.
