LOS ANGELES, May 23 (Xinhua) -- NASA's Gravity Recovery And Interior Laboratory spacecraft (Grail) will begin final preparations for a launch on a Moon mission in late summer, the Jet Propulsion Laboratory (JPL) said on Monday.The dynamic duo will orbit the moon to determine the structure of the lunar interior from crust to core and to advance understanding of the thermal evolution of the moon, according to JPL in Pasadena, Los Angeles.After arriving at the Astrotech payload processing facility in Titusville, Florida last week, the Grail twins, known as Grail-A and Grail-B, were removed from their shipping containers Monday. Later this week, they will begin functional testing to verify their state of health, said JPL.The twins were shipped from Lockheed Martin Space Systems, Denver.Over the next four months at the Astrotech facility, the spacecraft will undergo final testing, fueling and packaging in the shroud that will protect them as the Delta II launch vehicle lifts them into space. The spacecraft will then be transported to the Cape Canaveral Air Force Station for installation atop the rocket that will carry them toward the moon, JPL said."We're only a few full moons away from a mission that will reveal clues not only into the history of the moon and Earth, but will provide important data for future lunar exploration," said Maria Zuber, Grail's principal investigator, based at the Massachusetts Institute of Technology.Grail will be carried into space aboard a United Launch Alliance Delta II Heavy rocket lifting off from Launch Complex-19 at the Cape Canaveral Air Force Station in Florida. The launch period opens Sept. 8, 2011, and extends through Oct. 19. For a Sept. 8 liftoff, the launch window opens at 5:37 a.m. PDT (8:37 a.m. EDT) and remains open through 6:16 a.m. PDT (9:16 a.m. EDT).Grail-A and Grail-B will fly in tandem orbits around the moon for several months to measure its gravity field in unprecedented detail.The mission will also answer longstanding questions about Earth' s moon, and provide scientists a better understanding of how Earth and other rocky planets in the solar system formed, according to JPL, which manages the Grail mission.

BEIJING, Jan. 31 (Xinhua) -- The Ministry of Culture, along with seven other central departments, announced on Monday the launching of the "parental watch project" in the online games industry beginning March 1.The project will require online game companies to set up a web page, enquiry hotline and other special channels for parental supervision of their children.Besides, these companies shall authorize parents, who want to monitor and control their children playing online games, to take measures to limit or ban the playing.Also, the online game companies shall provide help to parents in supervising their children's online game accounts and preventing them from playing improper games, as part of the project.The culture ministry tested the project in several online game companies in Feb last year, which proved effective in helping juveniles overcome addictions to online games.

JAKARTA, April 27 (Xinhua) -- Marine scientists will begin conducting an ecological survey in eight locations throughout the resort island in Indonesia's Bali province that could be developed as marine managed areas due to their biodiversity and coral structure, the Jakarta Post quoted an expert as saying on Wednesday.The survey, which will take place from April 29 to May 11, will be carried out by four international scientists and local scientists from universities.Ketut Sarjana Putra, the marine program director with Conservation International Indonesia, said Tuesday the survey was aimed at identifying marine species and their population in each of the eight locations.Selected from 25 potential marine conservation zones, the eight locations are Pulaki and Pemuteran, Lovina, Les Village, Tulamben and Amed, Padangbai, Nusa Penida, Bukit Uluwatu Peninsula and Perancak Beach. "We will go around Bali, starting from Sanur in the south, heading east, then covering the northern and the western areas, then back to the south," Ketut told the daily.The survey is part of a process to build a network of marine protected areas to effectively manage the island's marine and coastal resources to sustain environmental and socioeconomic value and benefits, with priority given to the eight locations.

BEIJING, Jan. 21 (Xinhua) -- China's State Council, or Cabinet, Friday published the newly adopted regulations on expropriation of houses on state-owned land and compensation.The new rules, which took effect upon the issuing, took the place of the 2001 regulations on administration of the housing demolition and relocation in cities.The new rules specifically stated that neither violence or coercion may be used to force homeowners to leave. Nor could measures, such as illegally cutting water and power supplies, be used in relocation work.The new rules also banned land developers' involvement in the demolition and relocation procedures, as well as demolition by local governments without court approval.Moreover, the new regulations ensured fair prices for homeowners by providing that compensation for expropriated homes should be no lower than the sum of the market price of similar properties at the time of an expropriation.The regulations were first reviewed at a State Council executive meeting in December 2007. Later, public opinion was twice sought in 2010 after revisions had been made to the regulations.An executive meeting of the State Council Wednesday gave in-principle approval to the regulations.
