The second phase involves a series of telescopes， code-named Ngari No. 2， located about 6，000 meters above sea level， Yao said. The budget for the two-phase Ngari gravitationa

Chinese Unmanned Submersibles Descend 10，000 Meters Three unmanned deepsea devices reached depths of more than 10，000 meters upon completing tests in the Pacific， Chinese scientists said.

Three deepsea landing devices descended to the trench from December 25 to 27. 4The first Rainbow Fish landing device took photographs， the

All three submersibles reached depths exceeding 10，000 meters， and the third device brought back 103 amphipods， Cui said. The Rainbow Fish project is a mobile lab cofunded by the state and with private capital. “The succes

New Geological Map of the Moon Charted in China Chinese scientists are charting a 1：2.5 million scale geological map of the Moon. Five universities and research institutes have set standards for the digital m

The map will provide information about geology， structure and rock types， and so reflect the timeline of the Moons evolution. Geologist Chen Shengbo at Jilin University in no

The 5map will feature lunar topography such as geographic fractures and the size， appearance， and structure of craters， Chen said. Mapping relies on data and images sent by c
16、ircumlunar satellites from home and abroad， Chen said. Charting a lunar map differs from mapping the Earth， where if scientists are not sure about their information they can go any area in person to check. But Chinas satellites have captured global images of the Moon， which contribute considerably to the precision of the countrys lunar maps. A sketch version of the map will be complete in 2018， and released before 2020.
