A satellite model of China's Tianhe Project, which aims to transfer water via an "air corridor", is on display at the 12th China International Aviation and Aerospace Exhibition in Zhuhai, South China's Guangdong Province.
By 2022, a network of six such satellites will be formed, meaning the satellite will revisit the Sanjiangyuan area, northwestern Qinghai province, every hour, or 24 times a day, and provide technological support to water vapor transportation in the air corridor.
