China launch of relay satellite Queqiao-2 for lunar probe mission successful

China National Space Administration (CNSA) said on Friday its launch of a key signal relay satellite was a "complete success" and it would serve as the communication bridge for its future lunar probe missions for years to come, state media reported. China launched the satellite Queqiao-2, which was named after a mythological bridge made of magpies, and two miniature satellites, Tiandu-1 and Tiandu-2, on March 20. Queqiao-2 will be used as a communications bridge between the ground operations on earth and upcoming lunar probe missions on the far side of the moon until at least 2030.
