WASHINGTON, Jan. 1 (Xinhua) -- Twin U.S. spacecraft to study the moon from crust to core put themselves into the lunar orbit on New Year's Eve and New Year's Day, the country's space agency said.The second Gravity Recovery And Interior Laboratory, or GRAIL-B, reached its lunar orbit at 5:43 p.m. EST (2243 GMT) on Sunday, according to the National Aeronautics and Space Administration (NASA).The GRAIL-A started orbiting the moon at 5 p.m. (2200 GMT) Saturday.The insertion maneuvers placed the spacecraft into a near-polar, elliptical orbit with an orbital period of approximately 11.5 hours, NASA said.Over the coming weeks, the GRAIL team will execute a series of burns with each spacecraft to reduce their orbital period to just under two hours. At the start of the science phase in March 2012, the twin GRAILs will be in a near-polar, near-circular orbit with an altitude of about 55 km."NASA greets the new year with a new mission of exploration," Administrator Charles Bolden said in a statement. "The twin GRAIL spacecraft will vastly expand our knowledge of our moon and the evolution of our own planet."During GRAIL's science mission, the two probes will transmit radio signals precisely defining the distance between them. As they fly over areas of greater and lesser gravity caused by visible features such as mountains, craters and masses hidden beneath the lunar surface, the distance between the twin spacecraft will change slightly.Scientists will translate this information into a high-resolution map of the moon's gravitational field.The data will allow scientists to understand what goes on below the lunar surface and increase knowledge of how Earth and its rocky neighbors in the inner solar system developed into the diverse worlds we see today.

SAN FRANCISCO, Oct. 5 (Xinhua) -- Google announced Wednesday that Google Earth, the tech giant's virtual globe, map and geographical information program, has been downloaded more than one billion times since it was first introduced in 2005.According to Google's official blog, there have been more than one billion downloads of the Google Earth desktop client, mobile apps and the Google Earth plug-in. To celebrate the milestone, Google is aggregating all the interesting ways people have used Google Earth around the world and posting them on "www. OneWorldManyStories.com.""We never imagined our geospatial technology would be used by people in so many unexpected ways," said Google in the blog post.Google Earth maps the Earth by images obtained from satellite imagery, aerial photography and GIS (geographic information system) 3D globe. It also has versions of Moon, Mars and Sky, enabling users to see images and videos of the planets and distant galaxies.It is currently available in Google Earth, a free version with limited function, as well as Google Earth Pro and Google Earth Enterprise, subscription services with additional features intended for commercial use.

HOUSTON, Dec. 13 (Xinhua) -- NASA Johnson Space Center on Tuesday formed a partnership with Texas's largest tech incubator and accelerator, the Houston Technology Center (HTC), to help reach its goals of increasing private and public collaboration.The strategic partnership is aimed at expanding HTC's mission of accelerating the growth of emerging technology companies in the Houston region to support NASA's goals of increasing private and public cooperation, the parties said in news release."We are excited to partner with NASA Johnson Space Center in an effort to foster entrepreneurial opportunities to the transitioning workforce in the Bay Area," said Walter Ulrich, CEO of Houston Technology Center."The combination of NASA's incredible technologies and HTC's powerful entrepreneurial resources presents the potential for immense economic development," he said.HTC is committed to growing a sustainable entrepreneurial network that will benefit the surrounding the space center for years to come including its future missions beyond low earth orbit. HTC will seed the future workforce through its close ties with the major universities and with science, technology, engineering, math programs and objectives, according to the news release.NASA and the Houston Technology Center began their partnership earlier this year when they originally formed plans to open an office to help former contractors near the Johnson Space Center.With the signing of the Space Act Agreement on Tuesday, the two sides move forward with retraining contractors and helping them get new jobs in the Houston area.An estimated 4,000 people are expected to lose their jobs when the space shuttle program is completed.

BEIJING, Jan. 3 (Xinhua) -- A collection of China's nine white papers issued in 2011 has been published in both Chinese and English, according to a statement issued by the publisher on Tuesday.By giving a clear and precise illustration of China's policies, principles and progress in subjects like national defense, law, climate change and international trade, the white papers can help the world know about, and understand, China, the statement said.The white papers are titled, "China's National Defense in 2010," "China's Foreign Aid," "Sixty Years Since the Peaceful Liberation of Tibet," "China's Peaceful Development," "The Socialist System of Laws with Chinese Characteristics," "New Progress in Development-oriented Poverty Reduction Program for Rural China," "China's Policies and Actions for Addressing Climate Change (2011)," "China's Foreign Trade" and "China's Space Activities in 2011."The white papers were all published by the Information Office of the State Council on behalf of the Chinese government.The latest one on space activities was issued last Thursday.
