WASHINGTON, March 25 (Xinhua) -- NASA's Stardust spacecraft depleted fuel and ceased operation on Thursday after a 12-year run, the U.S. space agency said Friday."This is the end of the spacecraft's operations, but really just the beginnings of what this spacecraft's accomplishments will give to planetary science," said Lindley Johnson, Stardust-NExT and Discovery program executive at NASA headquarters in Washington."The treasure-trove of science data and engineering information collected and returned by Stardust is invaluable for planning future deep space planetary missions."Artist's concept of Stardust spacecraft nearing EarthLaunched on Feb. 7, 1999, Stardust flew past the asteroid named Annefrank and traveled halfway to Jupiter to collect the particle samples from the comet Wild 2. The spacecraft returned to Earth's vicinity to drop off a sample return capsule eagerly awaited by comet scientists.NASA re-tasked the spacecraft as Stardust-NExT to perform a bonus mission and fly past comet Tempel 1, which was struck by the Deep Impact mission in 2005. The mission collected images and other scientific data to compare with images of that comet collected by the Deep Impact.The Stardust-NExT met all mission goals, and the spacecraft was extremely successful during both missions. From launch until final rocket engine burn, it travelled approximately 3.54 billion miles.After the mileage logged in space, the Stardust team knew the end was near for the spacecraft. With its fuel tank empty and final radio transmission concluded, the most traveled comet hunter will move from NASA's active mission roster to retired."This kind of feels like the end of one of those old western movies where you watch the hero ride his horse toward the distant setting sun -- and then the credits begin to roll," said Stardust-NExT project manager Tim Larson from NASA's Jet Propulsion Laboratory in Pasadena, California. "Only there's no setting sun in space."

PARIS, April 22 (Xinhua) -- Heavy load launcher Ariane 5 lifted off two communication satellites, Yahsat Y1A and Intelsat New Dawn, at around 6:37 p.m. local time (2137 GMT) on Friday from Europe's Spaceport in French Guiana.Yahsat Y1A is the first United Arab Emirates satellite launched by Arianespace. It is built by Astrium and Thales Alenia Space and will be positioned at 52.5 degrees East. With a design life of 15 years, it will be operated by the Al Yah Satellite Communications Company, a telecommunications company indirectly controlled by the Abu Dhabi Government.Weighing around 5,935 kilograms at lift-off, Yahsat Y1A was expected to be separated first around 27 minutes after the launcher started the flight.The second passenger Intelsat New Dawn was built by Orbital Sciences Corporation and weighs about 3,000 kilograms. Also with a designed life span of 15 years, it is planned to be positioned at 32.8 degrees East.Via the second mission of Ariane 5 in 2011, Yahsat Y1A will provide customized relay services for the government and commercial sectors in the Middle East, Africa, Europe and Southwest Asia, while Intelsat New Dawn will work as a part of the global Intelsat fleet, offering service for Africa.This launch, the 201st of an Ariane family vehicle since 1979, brought to 22 the number of Intelsat satellites serving Africa, according to the launching company.Originally scheduled for liftoff on March 30, this dual-payload mission was delayed following an interruption of the final countdown when an incorrect displacement of one of the engine's actuators was detected, Arianespace said in a statement. The launching center planned to have six liftoffs of Ariane 5 through this year.

WASHINGTON, May 25 (Xinhua) -- Two U.S. astronauts conducted the third of four scheduled spacewalks for space shuttle Endeavour 's STS-134 mission on Wednesday morning, the U.S. National Aeronautics and Space Administration (NASA) announced.Endeavour's mission specialists Drew Feustel and Mike Fincke completed a six-hour-54-minute spacewalk at 8:37 a.m. EDT (1437 GMT). They completed all planned tasks, installing cables to increase redundancy for the power system on the Russian segment of the station, completing the external wireless antenna system work Feustel and Greg Chamitoff began during the first spacewalk, and installing a power and data grapple fixture to Zarya. The fixture will allow the station's robotic arm to "walk" to the Russian segment, extending its reach by using that grapple fixture as a base.It was the 247th spacewalk conducted by U.S. astronauts, and the 158th in support of space station assembly and maintenance, totaling 995 hours and 13 minutes. If everything goes as planned, the 1,000th hour of space station assembly and maintenance will be logged on Friday.Endeavour lifted off on May 16 from the Kennedy Space Center in Florida, to deliver to the International Space Station a 2-billion- dollar, multinational particle detector known as the Alpha Magnetic Spectrometer (AMS).AMS, a particle physics detector, is designed to search for various types of unusual matter by measuring cosmic rays. Its experiments are designed to help researchers study the formation of the universe and search for evidence of dark matter, strange matter and antimatter.NASA's 30-year-old shuttle program is ending due to high operating costs. The Obama administration wants to spur private companies to get into the space taxi business, freeing NASA to focus on deep space exploration and new technology development.There were initially five space shuttles in the fleet -- Challenger exploded shortly after liftoff in 1986 and Columbia disintegrated on its way back to Earth in 2003. Discovery retired earlier this year, while Endeavour is currently on its final mission. A last mission for Atlantis is scheduled for July, though funding for Atlantis remains in question.The sixth shuttle, Enterprise, did test flights in the atmosphere but was never flown into space. It is already on display at a museum outside Washington.When the U.S. space shuttle program officially ends later this year, the Russian space program's Soyuz capsule will be the only method for transporting astronauts to and from the station.
