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.

BEIJING, May 28 (Xinhua) -- The issue of third-party online payment permits in China this week will boost the sector's development through giving it a legal status, analysts said.The People's Bank of China (PBOC), or the central bank, on Thursday announced its first batch of electronic payment licenses to 27 qualified third-party online payment platforms, including Alipay, Tenpay and 99bill.It also stipulated that all the third-party payment businesses should obtain licenses before September, or cease doing business.The move has long been awaited after the central bank said in June last year that non-financial institution payment service would be regulated, and that all businesses involved in the service must get licenses before Sept. 1, 2011.The license covers payment transactions such as Internet payment, mobile phone payment, bank card acquiring service, issuance and accept of prepaid cards and currency exchange.The move provides a legal status for the third-party payment sector so that it can develop in a more standard and healthy way, said Zhang Meng, an analyst with Analysys International, an Internet market information provider.Third-party payment enterprises refer to those non-financial operators who work as the third party between buyers and sellers to provide payment settlement through Internet, telephones or mobile phones.China has the world's highest number of Internet users, with about 457 million netizens, among whom 148 million were active online shoppers as of the end of last year.China's online payment topped 1.09 trillion yuan (167.29 billion U.S. dollars) last year. The figure was 397.3 billion yuan in the first quarter this year, almost doubled year-on-year.99bill CEO Guan Guoguang called the issue of the third-party payment licenses "a milestone" for China's e-payment sector.Requiring that enterprises must be licensed to operate e-payment businesses will help standardize the sector, improve services and boost integration of e-payment and e-commerce, said Guan.The first group of e-payment license holders include Alipay.com Co. Ltd, a unit of Alibaba Group Holding which owns the country's largest e-commerce website Alibaba.com Co. Ltd.; China UMS, a unit of China UnionPay Co. Ltd; Tenpay.com, an e-payment platform developed by Chinese Internet giant Tencent Holdings and Shengfutong, launched by Shanda Interactive Entertainment.Five applicants, however, failed to get licenses.Businesses with licenses will attract more investment and high-end personnel, says iResearch analyst Cheng Shanbao.For those without a license, they will be merged or have to pull out of the sector, according to Yeepay CEO Tang Bin.The central bank selected enterprises that have good management and risk control systems, as well as profit prospects, Zhang Meng said.Mergers are inevitable as the cut-off date of Sept. 1 is approaching, he added.The third-party payment enterprises mainly profit from 1 to 4 percent fees, but analysts believe profits from the fees might be reduced due to fierce competition.

WASHINGTON, March 9 (Xinhua) -- U.S. space shuttle Discovery landed safely at the Kennedy Space Center in Florida on Wednesday, ending its nearly 27-year flying career as the world's most- traveled spaceship.According to NASA, Discovery touched down at 11:57 a.m. EST ( 1657 GMT) after a 13-day resupply mission to the International Space Station (ISS)."For the final time: wheels stop," Discovery's commander Steven Lindsey called out as the shuttle rolled to a full stop.Discovery lifted off on Feb. 24 from the Kennedy Center and arrived at the space station on Feb. 26.During the mission, the astronauts installed a spare closet module on the space station, completed some important repairs and delivered the first humanoid robot, though it will need more time to be assembled and made operational.The 330-pound R2 consists of a head and a torso with two arms and two hands. Once it is unpacked -- likely several months after its arrival at the station -- it will initially be operated inside the Destiny laboratory for operational testing, but over time both its territory and its applications could expand.Aboard the station, its primary job for now is teaching engineers how dexterous robots behave in space. However, the hope is that through upgrades and advancements, it could one day venture outside the station to help spacewalkers make repairs or additions to the station or perform scientific work.

JOHANNESBURG, March 8 (Xinhua) -- In order to combat piracy and to improve maritime safety, South African authorities have begun using a sophisticated navigation satellite system, it was announced on Tuesday.Piracy, especially by Somalis, has been increasing along Africa east coast in recent years. The South African Press Association (SAPA) reported on Tuesday that Karl Otto, head of the South African Maritime Safety Authority (SAMSA) announced the surveillance tool at a conference in Durban.Called Long Range Identification and Tracking (LRIT), the system monitors and tracks vessels in waters south of the equator.Otto said the introduction of the LRIT followed concerns over the safety of seafarers, the safety standards of ships within South African waters.Otto said there were high levels of cargo at risk, such as fuels and oils.He said reasons for installing the system included the number of shipwrecks along the South African coast, and the threat of pollution of the marine environment by ships."It also serves as a mechanism to prevent piracy."Otto said the satellite system has the capacity to identify and track vessels up to 1,000 nautical miles (1,850 km) from the South African coastline as well as South African-flagged vessels anywhere in the world."This is a revolutionary development in the security of our seas," he said.SAMSA was determined to protect South Africa's seafarers, its coastline and the marine environment, Otto said.
