Queqiao satellites | |
Queqiao-2 relay satellite (Chinese: 鹊桥二号中继卫星; pinyin: Quèqiáo èr hào zhōngjì wèixīng; lit. 'Magpie Bridge 2 relay satellite'), is the second communications relay and radio astronomy satellites designed to support the fourth phase the Chinese Lunar Exploration Program,[6][7][8] after Queqiao-1 launched in 2018. The China National Space Administration (CNSA) launched the Queqiao-2 relay satellite on 20 March 2024 to an elliptical frozen orbit around the Moon to support communications from the far side of the Moon and the Lunar south pole.[9][10][11][12]
The name Queqiao (ch'wuh-ch'yow, "Magpie Bridge") was inspired by and came from the Chinese tale The Cowherd and the Weaver Girl.[9][8][13]
