Xuelong completed study at South Pole

CHINESE scientists have completed a geographic survey on Dome A, the highest elevation in the South Pole, after China's only icebreaker returned to its Shanghai base today. officials from the Polar Research Institute of China said today Xuelong (Snow Dragon), China's only icebreaker, carried out a series of research on Antarctic marine system, the South Pole climate and astronomy. Choosing a location for the observatory was one of their crew's top tasks, the institute officials said. "Dome A is the best choice for an observatory concerning its location and environment," said Zeng Honghui from the institute. "Research found Dome A has the best sky view on earth. Good visibility is the deciding factor for setting up an astronomical telescope." He said the telescope installed in the Dome A observatory can function like a space telescope. Officials said the construction plan has been approved by the Scientific Committee for Antarctic Research and has passed an international environmental evaluation. Other countries and international organizations are also planning to build observatories in other positions at the South Pole, officials said.
