(Photo provided to Xinhua) Chinese scientists are building a large survey telescope with a wide field and high resolution in northwest China's Qinghai Province. The telescope will be able to survey the entire sky from the Northern Hemisphere. Construction of the Wide Field Survey Telescope (WFST), an optical instrument measuring 2.5 meters in diameter, has already started in Lenghu Town, which has an average altitude of approximately 4,200 meters. The town is known as China's "Mars Camp" due to its eerily eroded desert landscape that resembles the surface of the red planet.
