LOS ANGELES, April 1 (Xinhua) -- A NASA Gulfstream-III aircraft equipped with a synthetic aperture radar is scheduled to depart Sunday, April 3 on a nine-day mission to image Hawaii volcanoes, the Jet Propulsion Laboratory (JPL) announced on Friday.The aircraft will fly from the Dryden Aircraft Operations Facility in Palmdale, California to the Big Island of Hawaii to study the Kilauea volcano that recently erupted, said JPL in Pasadena, Los Angeles.The mission will help scientists better understand processes occurring under Earth's surface, JPL said.Developed by JPL, the Uninhabited Aerial Vehicle Synthetic Aperture Radar, or UAVSAR, uses a technique called interferometric synthetic aperture radar that sends pulses of microwave energy from the aircraft to the ground to detect and measure very subtle deformations in Earth's surface, such as those caused by earthquakes, volcanoes, landslides and glacier movements.As the Gulfstream-III flies at an altitude of about 12,500 meters, the radar, located in a pod under the aircraft's belly, will collect data over Kilauea, according to JPL.The UAVSAR's first data acquisitions over this volcanic region took place in January 2010, when the radar flew over the volcano daily for a week. The UAVSAR detected deflation of Kilauea's caldera over one day, part of a series of deflation-inflation events observed at Kilauea as magma is pumped into the volcano's east rift zone.This month's flights will repeat the 2010 flight paths to an accuracy of within 5 meters, or about 16.5 feet, assisted by a Platform Precision Autopilot designed by engineers at NASA's Dryden Flight Research Center on Edwards Air Force Base, California, JPL said.By comparing these camera-like images, interferograms are formed that reveal changes in Earth's surface, said JPL.Between March 5 and 11, 2011, a spectacular fissure eruption occurred along the east rift zone. Satellite radar imagery captured the progression of this volcanic event."The April 2011 UAVSAR flights will capture the March 2011 fissure eruption surface displacements at high resolution and from multiple viewing directions, giving us an improved resolution of the magma injected into the east rift zone that caused the eruption," said JPL research scientist Paul Lundgren."Our goal is to be able to deploy the UAVSAR on short notice to better understand and aid in responding to hazards from Kilauea and other volcanoes in the Pacific region covered by this study," Lundgren added.

ISTANBUL, May 3 (Xinhua) -- The world's water consumption will increase by 40 percent over the next two decades and efforts to meet this demand must increase radically, the secretary-general of the 5th World Water Forum said here on Tuesday.Oktay Tabasaran said in his opening speech at the World Water Forum that "water consumption will increase by 40 percent in the coming 20 years, reaching 6.9 trillion cubic meters per year ( compared with the 4.5 trillion used currently), and an amount of 200 billion U.S. dollars must be spent annually in order to afford this."He said such figures indicated the urgent need for countries to engage in efficient cooperation with each other to address water- related issues.Some 50 out of the world's 188 countries have serious concerns in providing drinking and irrigation water, due to careless and inefficient use of water, according to Ismail Ugur, the general director of Turkey's State Waterworks Authority."If we fail to come up with solutions, starting from 2015 there will be droughts (in many parts of the world) and people will start suffering from diseases caused by lack of water, as of 2025, " Ugur said.Ekmeleddin Ihsanoglu, head of the Organization of the Islamic Conference (OIC), said that ensuring reliable access to water is crucial to promoting peace and security in the Middle East, where many countries are facing dramatic declines in available water."In some regions of the Muslim world, water availability is predicted to be cut in half by 2050, even without taking into consideration the effects of climate change," he said in his opening speech.The OIC chief called for increased cooperation among member states and countries outside the region, announcing the group's progress in preparing its own "Water Vision" document and forming an OIC Water Council to address water-related concerns."In its first phase, the Water Vision will outline a framework of cooperation on water-related issues in terms of water-sharing experience, capacity development, technology transfer, water governance and institutional reforms," Ihsanoglu said.He cited the Friendship Dam, to be constructed on the Orontes River at the Turkish-Syrian border, as an excellent example of cooperation and peace among neighboring countries in the field of water.Charity Ngilu, minister for water and irrigation of Kenya, stressed the importance of water in promoting peace, especially in regions where water scarcity prevails."There have been many conflicts caused by water scarcity not only among African countries, but even within regions of the same country," She said, adding Kenya would ask Turkey for cooperation and assistance in water management and other related issues.

WASHINGTON, April 4 (Xinhua) -- The U.S. National Aeronautics and Space Administration (NASA) announced on Monday that following discussions among the International Space Station partners on Sunday, it is delaying the launch of space shuttle Endeavour's STS- 134 mission to April 29 from April 19.The new launch time is set for 3:47 p.m. EDT (1947 GMT) on Friday, April 29."The delay removes a scheduling conflict with a Russian Progress supply vehicle scheduled to launch April 27 and arrive at the station April 29," NASA said in a statement.NASA managers will hold a Flight Readiness Review on Tuesday, April 19, to assess the team's readiness to support launch. An official launch date will be selected at the conclusion of the meeting.Endeavour will deliver to the space station a 2-billion-dollar, multinational particle detector known as the Alpha Magnetic Spectrometer.

BAODING, Feb. 2, (Xinhua) -- All-out efforts should be made to combat drought for a summer grain harvest, said Chinese President Hu Jintao Wednesday in an inspection tour to north China's Hebei Province."We need to adopt comprehensive measures to ensure supply of capital, technologies, facilities and materials to enable winter wheat to safely grow through the winter," said Hu, when inspecting drought conditions at a wheat field in Xishanbei Township of Baoding City, Hebei.Over the past three months, North China has been hit by severe drought, seriously threatening normal agricultural production.Hu, who is also general secretary of the Communist Party of China (CPC) Central Committee and chairman of the Central Military Commission, made the inspection visit in Baoding from Tuesday to Wednesday, to welcome the Spring Festival, or China's Lunar New Year, with local officials and residents.Hu beat a drum together with villagers during a new year celebration in Shijiatong Village, Xishanbei Township of Baoding.The president visited the home of Yan Deshu, an aged CPC member in the village, and pasted the Chinese character "Fu", meaning fortune and happiness, on the gate of Yan's yard.Hu also visited a long-distance coach station in Baoding, and extended Spring Festival greetings to passengers, station workers and volunteers.Hu inspected a unit of armed police in Baoding and made Chinese dumplings together with the officers and soldiers.

BEIJING, Feb. 13 (Xinhua) -- Chinese Premier Wen Jiabao has invited a group of ordinary people from all walks of life to seek their opinions on drafts of a government work report and the country's economic and social development blueprint for the next five years.The representatives, including a farmer, a migrant worker, a rural doctor and a community worker, were invited to Zhongnanhai, the central leadership compound in downtown Beijing, on Jan. 25. Some details of the meeting were made public on Sunday.At the meeting, Wen said, "Ordinary people are in the best place to evaluate government's work, and listening to public opinion will allow us to know how government policies are carried out at grass-roots level, and what difficulties people are facing."Liu Hongwei, a farmer from northeastern Heilongjiang Province, suggested that government increases investment in agricultural water conservancy projects in case of natural disasters such as severe drought this winter in north China.Wen said this year the government would invest more in water conservancy while starting retrofitting the grid in rural areas to guarantee electricity supply for both residential consumption and irrigation of crops.Wen also assured Liu that the government would raise purchasing price of grains so as to protect the interests of grain farmers.Xie Yuanli, an electric welder from northeastern Jilin Province, expressed his wish that governments give greater support and care to industrial workers.Dong Zhiping, a migrant worker working on construction site in central Hunan Province, complained that some enterprise owners refuse to pay migrant workers insurance against work-related injuries, and many migrant workers are not aware of their rights."Once a worker gets injured, his family would suffer grave financial difficulties without the insurance cover," Dong said.Wen said the government was working on the issue, such as promoting better implementation of government regulations on workplace injury-related insurance, which became effective in 2003.The meeting also touched upon issues of favorable policies to small and medium-sized enterprises, fair treatment of village doctors, stronger support to facilities for senior citizens, boosting space science and technology and improving vocational training, among others.The drafts of the 12th five-year program, or the national development plan for 2011 to 2015, and the government work report will be delivered for review early next month at a plenary session of the National People's Congress (NPC), China's national legislature.
