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.

STOCKHOLM, Feb. 20 (Xinhua) -- The exhibition of the Chinese Terra-cotta Army here was an enormous success, project organizer Sanne Houby-Nielsen said Sunday.About 320 objects, including terra-cotta warriors from the ancient Chinese Qin Dynasty and other terra-cotta figures from Han Dynasty, were exhibited at the Far Eastern Antiquities Museum during the event, which ended Sunday.Houby-Nielsen, who is director of the museum and also director-general of the country's National Museums of World Culture, told Xinhua in an exclusive interview that the total number of visitors was around 350,000, more than double the expected turnout.This was the highest number of visitors the museum has ever experienced in its history since it was established in the 1940s, said Houby-Nielsen, adding that the exhibition was originally scheduled to end on Jan. 16, but "a great pressure from the audiences" prompted the museum to extend it till Sunday."It is an exhibition which won the most audience for many years in Sweden. We feel particularly happy because it was a very good display of the story of the first emperor and the early Han Dynasty," she said."We felt such a huge interest that we have to prolong it. So we were very grateful that it was possible to prolong the exhibition," she added.The exhibition was declared open by Swedish King Carl XVI Gustaf in August. Many of the ancient Chinese artifacts have never been exhibited outside China.Swedish Sinologist Cecelia Lindqvist commented that the event helped people understand the current China by looking at the history of China presented in the exhibition.

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 State Councilor Meng Jianzhu left here Sunday for visits to the Democratic People's Republic of Korea (DPRK), Laos, Singapore and Malaysia.Meng, who is also Chinese Minister of Public Security, is traveling to the countries at the invitation of the DPRK Minister of People's Security Ju Sang Song, Lao Minister of Public Security Thongbanh Seng-aphone, Singaporean Minister for Home Affairs and Minister of Law K Shanmugam, and Malaysian Minister of Home Affairs Hishiammuddin Tun Hussein.
