Check out how staff members maintain the world's largest single-dish radio telescope with the help of a balloon.

PINGTANG, Sept. 1 (Xinhua) --Researchers with the China-based FAST, the world's largest single-dish radio telescope, tested a microgravity mechanism in the maintenance of the telescope's 4,450-panel reflector. The micro-G mechanism aims to help reduce the maintenance staff's body weight to a value within the reflector panels' range of durability using a helium-filled balloon 7.6 meters in diameter. Located in a naturally deep and round karst depression in southwest China's Guizhou Province, FAST was put into trial operation in September 2016.
