MOSCOW, April 22 (Xinhua) -- The Russian Space Forces has re-established contact with a military satellite, Geo-IK-2, which went missing in February, local media reported Friday.According to a spokesman from the Defense Ministry, Interfax news agency said the Space Forces had already received telemetric information from the satellite and collection and analysis of the data were currently underway.After studying the information, the Defense Ministry would make a decision regarding the further use of the satellite, the spokesman said.A Rokot light-class carrier rocket carrying with the Geo-IK-2 satellite blasted off Feb. 1 from Russia's Plesetsk launching site, but placed the satellite in an incorrect orbit. After the launch, the Defense Ministry announced it had lost contact with the Geo-IK-2 and later abandoned the satellite.The Russian Space Forces then grounded launches of all Rokot light-class carrier rockets until the completion of an investigation into the failed launch.

MOSCOW, March 11 (Xinhua) -- A new crew which are to depart for the International Space Station (ISS) at the end of March have successfully passed the pre-flight tests, the Russian Federal Space Agency (Roscosmos) announced on Friday.At a press conference held at Russia's Cosmonauts Training Center, a Roscosmos spokesman said two Russian cosmonauts Andrei Borisenko and Alexander Samokutyaev and a U.S. astronaut Ronald Garn will leave for the ISS by a Russian Soyuz-TM-21 spacecraft on March 30.On March 17, the three crew members and their backup crew members, Anton Shkaplerov, Anatoly Ivanishin and Daniel Burbank, will make their final preparation for the space trip in the Baikonur space site in Kazakhstan.According to the Roscosmos, the three main crew members are expected to spend 170 days in the ISS. During the period, they will receive two U.S. space shuttles and three Russian Progress cargo ships and conduct a spacewalk.The agency also revealed the Soyuz-TM-21 spacecraft scheduled for the ISS was named as Gagarin.The year of 2011 was announced as Russia's Space Year to celebrate the 50th anniversary of the launch of the first Russian manned space flight carrying cosmonaut Yuri Gagarin in 1961 for a 90-minute flight.

JERUSALEM, May 8 (Xinhua) -- Israeli researcher Jacob (Koby) Scheuer, from the Tel Aviv University (TAU) School of Electrical Engineering, has developed a nano-scale gyroscope, the Ha'aretz daily reported Sunday.Scheuer developed a new optic-fiber nano-sensor four years ago, along with an optic gyroscope that works in conjunction with the sensor. As he developed the devices, it occurred to him that his discovery could be harnessed to surgical needs, virtual reality, or communications, said the report."What we developed here is an optic gyroscope," Scheuer told Xinhua in a recent interview on Sunday, "like the others, but the breakthrough is that we found a way to measure rotation in a very, very small device using the optic sensor."Optic gyroscopes emit light when they rotate, and change its wavelength when there is any change in the speed of rotation, making it possible to measure velocity and position by the differences in light.Scheuer's gyroscope, however, is so small in comparison to the others commonly used in planes, trains and vehicles, that it can be used in cell phones or watches and does not need satellite connection like the ubiquitous Global Positioning System.The applications of this gyroscope and optic sensor are almost endless, as Scheuer puts it."It can be a pill that you swallow and can move through your body to take pictures or release drugs in a localized area," the researcher explained, "or it can be used by a doctor to operate on a patient who is thousands of kilometers away.""Our gyroscope has complete independent navigation capability, which the others don't have," he stressed.Though the new optic gyroscope works in theory, it still hasn't been tried in out in reality. "It will take some time until we can empirically demonstrate our work, I would say about three to five years," Scheuer added.Alongside the gyroscope, Scheuer continues to work on the optic sensor, whose applications can also be found in security, such as an information security system developed by Scheuer to safeguard online information that acts as a key bearer."When both parties have 'the key' it's virtually impossible to hack the information sent," Scheuer noted, terming the development as a "total paradigm change."

  

CHIAYI, Feb. 26 (Xinhua) -- Chen Yunlin, the Chinese mainland chief negotiator with Taiwan, discussed cooperation prospects on Friday with fishermen and farmers in Chiayi in southern Taiwan.Chen, president of the mainland's Association for Relations Across the Taiwan Straits (ARATS), led a 50-member delegation and spoke at a seminar attended by more than 70 business people from both the mainland and Taiwan.He said small and medium-sized enterprises on both sides "played an important role in cross-Strait economic development, employment and in maintaining social stability.""Small- and medium-sized businesses are an important part of cross-Strait economic exchanges," he said, adding that among the more than 80,000 Taiwanese enterprises investing on the mainland, over 50 percent are small and medium-sized companies.Chen said that efforts should be made to enhance cooperation between small and medium-sized enterprises on the mainland and those in central and southern Taiwan.The mainland delegation arrived in Chiayi from Kaohsiung after investigating the investment environment with local business leaders. They arrived in Taipei on Wednesday at the invitation of Chiang Pin-kung, chairman of Taiwan's Straits Exchange Foundation (SEF). Both the SEF and the ARATS are authorized by the two sides to handle cross-Strait affairs.Chen said that since 2005, the mainland bought a large amount of farm and fishing products from Taiwan, which greatly boosted sales of Taiwanese products."Many renowned mainland distribution firms are present here at the seminar to seek cooperation opportunities with Taiwan's farmers and fishermen so that the sale of Taiwanese products on the mainland could increase steadily," he said.Chiang said the farming and fishing industries were the most important sectors in southern Taiwan.He added that the tax-reduction plan of the cross-Strait Economic Cooperation Framework Agreement's (ECFA) "early harvest" program, which took effect on January 1, covered 13 categories for farming products and five categories for fishing goods. Chiang said the plan was an opportunity for the industry to expand its exports to the mainland.He noted that the "early harvest" program's duty exemption also covered sectors like textiles, machinery components, and "all related to small- and medium-sized enterprises."Chiang said Friday's seminar was meant to promote cooperation between smaller businesses across the Strait, to deepen the effect of the ECFA to benefit both sides.The mainland delegation will continue its trip in southern Taiwan and return to Taipei late Saturday. They will visit Taipei's Neihu Industrial Park on Sunday before leaving the island on Monday.
