CSTAR Telescope Array in China arrived in the highest point of the Antarctic Dome A Inland

Following the January 18, 2005 for the first time for China to achieve the human from the ground to reach the Antarctic ice sheet after the peak of Dome A, the 24th Chinese Antarctic icecap expedition team expedition on January 12, 2008 once again get called " not close to the very human, "the highest point of the Antarctic inland ice dome A. The last difference is that the expedition carried out including the Observatory Dome A site survey and installation of our first comprehensive framework for small optical telescope array CSTAR for astronomical observation.
Antarctic Dome C has been confirmed on the ground is the best astronomical observatory sites, according to the similarity of the terrain, the first Chinese scientific expedition team landed Dome A is likely to be a better Observatory site, which for the Chinese astronomy The development provides an excellent opportunity. By the end of 2006, Chinese astronomers and astronomical instruments experts made the first astronomical equipment Antarctic station development program, that is, a small telescope array CSTAR China Antarctic research, the plan by the Nanjing Institute of Astronomical Optics Technology, Purple Mountain Observatory, National Astronomical Observatory in collaboration of which the main telescope from the Nanjing Institute of Astronomical Optics Technology for Development.
The comprehensive site visit organized by the Hong Kong Observatory Antarctic Astronomical Center of Chinese leadership, China, Australia and the U.S. astronomers to participate in international cooperation in the project have been incorporated into "the International Polar Year," the core of China's Action Plan?? Panda program. Among them, the telescope section includes CSTAR and 3 sets of 50cm/75cm the Schmidt telescope (AST3), now Nanjing Institute of Astronomical Optics Technology is developing AST3, planned 2009/2010 installed in the Dome A.
CSTAR is 4 sets of 14.5 cm diameter field of view telescope with a rack in the form of a small telescope array, the angular field of view is 4.5 ° x4.5 °, focal ratio of 1.2, respectively, white and configuration g, r, i four kinds of filters, detectors for the 1kx1k frame transfer CCD. CSTAR is mainly for the scientific objectives of monitoring and statistical analysis of variable stars to find extrasolar planets, supernovae. To test the telescope in the Antarctic work under extreme environmental conditions, four telescopes were carried out at low temperature test. After just 10 months time, CSTAR in Nanjing Institute of Astronomical Optics Technology successfully developed; October 10, 2007, through the acceptance.
November 12, 2007, CSTAR as the 24th Chinese Antarctic scientific exploration ship destined for Antarctica, on January 12, 2008 successfully reached the highest point of the Antarctic inland ice dome A. Currently participate in this expedition, two astronomers are installation CSTAR and Central Australia, USA to jointly develop the site for the measurement of the Antarctic plateau station automatic astronomical observatory PLATO.
China's 24th Antarctic expedition inland icecap expedition team once again on January 12 to reach the highest point of the Antarctic inland Dome A, which is following the January 18, 2005 our country's first human to reach the Antarctic ice sheet ice from the ground Dome A peak, once again boarded called "human is not close to the pole" of the Dome A. The most striking is that this is the first time astronomers inland into the Antarctic and reach the highest point, it marks the summit of the Antarctic ice sheet the human stand the mysteries of the universe to explore a new milestone.
Dome A is the highest point of the Antarctic ice sheet elevation of 4093 meters, theoretically predicted for the planet's best sites for astronomical observations one. The Observatory site inspection activities integrated into the "International Polar Year," the core of China's Action Plan is led by the Chinese Antarctic Astronomical Center, China, Australia and the United States astronomers to participate in international cooperation projects.
The Observatory site comprehensive survey of the Antarctic plateau top priority is to establish automatic astronomical observatory, its main purpose is for determination of astronomical site selection parameter, for the near future of human conduct astronomical observations in the Antarctic inland activities to provide detailed scientific evidence. Astronomical observatories astronomical automatically by the engine, the host computer, satellite communications, solar panels, automatic weather stations, and the observation of atmospheric Seeing (seeing), sky background, the aurora and other range of facilities. In addition, the Chinese Academy of Sciences National Astronomical Observatories, Nanjing Institute of Astronomical Optics Technology, Purple Mountain Observatory and the country was jointly developed by Hong Kong Observatory Headquarters small optical telescope array CSTAR will be monitoring the Antarctic more than 20 square degrees zenith of all objects within, for variable star monitoring and statistical analysis search for extrasolar planets, supernovae, etc.. CSTAR is the first set of the Antarctic optical astronomical facilities.
According to the State Observatory, Chinese Academy of Sciences, said Yan Jun, 20 years ago, astronomers began to prepare our country to start astronomical observations in the Antarctic. We have prepared a common implementation of the observing program with the United States, and also developed for this purpose had a special weather conditions for the Antarctic horizon type 40 cm telescope. Unfortunately, for some reason did not complete the program. Astronomers in China this year, with the inland Antarctic expedition on board the highest point of the first to open the South Pole, led by China's international cooperation projects in astronomy, it can not only greatly improve the technical level of China's astronomical observations, but also for our country in the dark matter and dark energy and the detection of extrasolar planets and other cutting-edge scientific research in the field into the world's advanced level provided a rare opportunity.
The expedition of astronomers to participate in Antarctic inland national Observatory and Purple Mountain Observatory researcher Zhou Xu Zhu Zhenxi Research Associate. As the astronomical community first to go to the Antarctic expedition, who will be responsible for Dome A in the installation, commissioning astronomical equipment, the establishment of an astronomical observatory tasks automatically. Currently they are full of energy, good health, are astronomical for the upcoming construction of the station automatically make the necessary preparations.
