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.

BEIJING, Feb. 12 (Xinhua) -- China's recent revocation of a national scientific award due to academic fraud has been welcomed by the public, but experts warn the country still has a long way to go to bring an end to such dubious academic practices.On Feb. 1, China's Ministry of Science and Technology, revoked the State Scientific and Technological Progress Award (SSTPA) given to Li Liansheng, former professor of Xi'an Jiaotong University in 2005.An investigation found Li had plagiarized others' works and fabricated data in his winning project, a research on key technologies for designing and manufacturing scroll compressors. Li was investigated after the science ministry received tip-offs from six professors (including four retired) in his university.The ministry subsequently canceled his prize and retrieved the money awarded.Zhao Baojing, a senior official with the National Office for S&T Award, told Xinhua it was the first time China had withdrawn a national scientific honor.The revocation soon sparked pubic discussion over academic integrity. Tan Gang, a citizen in Shenzhen, wrote on his microblog, "Though the revocation came a bit late, it is progress. It's a warning against academic misconduct."Shi Ying, vice director of Shanxi Academy of Social Sciences, said, the move demonstrated China's "zero-tolerance" for academic fraud, and would help clean up the academic field."However, academic fraud is still rampant, which not only damages academic integrity, but also harms the innovative capacity of China in a broader sense," said Shi.Anti-fraud activist Fang Zhouzi, who runs a website on anti-academic fraud from his Beijing home, said "This is by far the harshest stance China has ever taken against academic fraud, which should be viewed as progress." He so noted China still has a long way to go in the fight against academic fraud.Fang said, the science ministry's move does not mean China is really cracking down on academic fraud. The plagiarist might have not been found out if it were not for years of unyielding efforts made by the six professors.The scandal again highlights that academic fraud is alive and well in China. A survey conducted among 30,078 respondents in 2009 by the China Association for Science and Technology (CAST) showed that nearly half of the science-related workers in China's research institutes, universities, medical institutes and hospitals think academic cheating is "common."Fang attributed the prevalence of academic fraud in China to lax punishments and loopholes in the academic evaluation system.Zero tolerance of academic fraudChina's science minister, Wan Gang, said on several occasions "We hold zero tolerance for academic fraud."However, Fang said "zero tolerance" was a slogan rather than the actual case. Many cases of academic fraud, even publicly exposed, were "tolerated" eventually. "Lax punishment makes academic fraud less costly."

BEIJING, Jan. 22 (Xinhua) -- Chinese President Hu Jintao's latest state visit to the United States bore rich fruit and opened a new chapter of cooperation between the two countries, Foreign Minister Yang Jiechi said Saturday.The tour, from Tuesday through Friday, came at the beginning of the second decade of the 21st century, on the 40th anniversary of the resumption of contact between the two countries and on the opening year of China's 12th five-year plan for national socioeconomic development, Yang noted.Meanwhile, the international situation was witnessing deep and complicated changes, and the China-U.S. relationship was forging ahead with increasing momentum while inevitably encountering some differences and disputes, he said.Against such a backdrop, the Chinese president held frank and in-depth talks with his U.S. counterpart, Barack Obama, and many other senior political figures, and reached important consensus on bilateral relations and a host of major regional and global affairs, Yang said.During the tightly scheduled trip, which saw Hu attend nearly 20 events in Washington and Chicago within 68 hours, the Chinese leader also reached out to the U.S. public, conveying China's resolution to advance China-U.S. ties, highlighting China's commitment to peaceful development and presenting China's image of peace, development, opening-up and progress, Yang said.The U.S. and international media, he added, attached great importance to and spoke highly of Hu's trip, hailing it as a historic visit at a crucial moment and whose significance was manifested partly in the top level reception with full pomp and ceremony given by the U.S. government.In summary, the latest step in China-U.S. diplomacy achieved rich results and cast a far-reaching influence not only upon the two countries themselves but upon the whole world, the Chinese foreign minister said.
