LOS ANGELES, May 25 (Xinhua) -- NASA project managers bade farewell to the Mars rover Spirit on Wednesday after sending a final set of commands to the stranded vehicle.This marks the completion of one of the most successful missions of interplanetary exploration ever launched, NASA's Jet Propulsion Laboratory (JPL) said."Last night, just after midnight, the last recovery command was sent to Spirit," said John Callas, the Mars Exploration Rover Project manager at NASA's Jet Propulsion Laboratory (JPL) in Pasadena, Los Angeles."It would be an understatement to say this was a significant moment. Since the last communication from Spirit on March 22, 2010, as she entered her fourth Martian winter, nothing has been heard from her."NASA has tried in vain to regain communication with Spirit since it got stuck in sand about two years ago. The rover last communicated on March 22, 2010, as Martian winter approached and the rover's solar-energy supply declined.NASA checked frequently in recent months for possible reawakening of Spirit as solar energy available to the rover increased during Martian spring, but to no avail.A series of additional re-contact attempts ended on Wednesday, designed for various possible combinations of recoverable conditions, according to JPL."Our job was to wear these rovers out exploring, to leave no unutilized capability on the surface of Mars, and for Spirit, we have done that," said Callas.

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.

SAN FRANCISCO, April 28 (Xinhua) -- Microsoft Corp. on Thursday posted quarterly revenue and earnings that both beat analysts' expectations.In its fiscal 2011 third quarter ended on March 31, the software giant reported revenue of 16.43 billion U.S. dollars, up 13 percent from the same period a year earlier.Net income and earnings per share were 5.23 billion dollars and 61 cents, representing increases of 31 percent and 36 percent respectively year-on-year.Analysts had expected earnings of 56 cents per share on revenue of 16.19 billion dollars, according to Thomson Reuters."We delivered strong financial results despite a mixed PC environment, which demonstrates the strength and breadth of our businesses," Peter Klein, chief financial officer at Microsoft, said in a statement."Consumers are purchasing Office 2010, Xbox and Kinect at tremendous rates, and businesses of all sizes are purchasing Microsoft platforms and applications," he added.Revenue at four of Microsoft's five major divisions posted double-digit growth in the quarter, indicating the increase of technology spending by enterprises as well as strong demand for the company's entertainment products.The entertainment and devices division saw the biggest revenue growth of 60 percent, which according to Microsoft, were driven by strong demand for its Kinect hands-free motion control system for Xbox 360 and continued strong sales of Xbox 360 console.However, revenue for the division of the company's flagship Windows operating system dropped 4 percent in the quarter, which Microsoft said was "in line with the PC trends."The performance of the Windows division may fuel new concerns that Microsoft's dominance in software for PCs is being threatened by Apple's iPad and tablet computers running other operating systems, some analysts noted.

UNITED NATIONS, April 1 (Xinhua) -- UN Secretary-General Ban Ki- moon on Friday called for greater public awareness of autism, in order to fight the stigma and discrimination facing those who suffer from the disorder.The statement came in a message to mark the annual World Autism Awareness Day, observed globally on April 2."Children and persons with autistic conditions face major challenges associated with stigma and discrimination, as well as a lack of access to support," said Ban."Far too many suffer terrible discrimination, abuse and isolation, in violation of their fundamental human rights," he added.Autism is a disorder that affects the brain's development of social and communication skills, and generally appears in the first three years of life."The number of children and people with autistic conditions continues to rise -- in every nation and in every racial, ethnic and social group," the secretary-general said.Ban said it is critical to support parents of children with the disorder and "create jobs for individuals with autism based on their skills and strengths, and improve public education to better meet the needs of students with autism."

LOS ANGELES, May 11 (Xinhua) -- U.S. researchers have found MRSA (methicillin-resistant Staphylococcus aureus) in meats sold at U.S. supermarkets, according to a study published on Wednesday.This is "community-acquired MRSA" that is transmitted by humans carrying the bacteria, researchers at Wayne State University in Detroit reported in the study appearing in the May 11 online edition of the U.S. Centers for Disease Control and Prevention's ( CDC's) journal Emerging Infectious Diseases.For the study, the researchers purchased 289 raw meat samples, including 156 beef, 76 chicken and 57 turkey samples, from 30 grocery stores in Detroit from August 2009 through January 2010.The researchers found that 22.5 percent of the samples were contaminated with S. aureus and six samples tested positive for MRSA.Of the six samples contaminated with MRSA, two were beef, three were chicken and one was turkey, the researchers said.The extent of MRSA contamination in meat varies by the type of meat and where the meat was processed, said lead researcher Yifan Zhang, an assistant professor in the department of nutrition and food science at the university.The germ is apparently being introduced by humans handling the meat, she said.According to another recent study, the strain of MRSA in meat in the United States is not the strain found in animals, Zhang noted."MRSA has always been found in human patients, but we found this in retail meat, so retail meat can be a reservoir of these bugs," said Zhang."When people handle food, they can get the bugs from the meat if the meat is already contaminated," she explained.The risk of becoming infected is especially high if you have open cuts or sores on your hands or skin, Zhang added.MRSA is common in hospitals and nursing homes, where it can cause serious illness and even death.But recently "community-acquired MRSA" has become a problem among some high school and college athletes who share equipment.This type of MRSA appears as a skin infection and is usually less serious, according to CDC.MRSA is killed when the meat is cooked thoroughly, experts say.Other precaution measures include:-- Wear gloves when handling meat, especially when there are wounds on the hands;-- Washing plates or utensils used to prepare food before using them again to eat; and-- Disinfect counters that have come into contact with meats.
