Persistent innovation pays off

Chen Luojing, a designer with the China Academy of Space Technology, is surprised by people's enthusiasm for the nation's space programs.

In a display during the 19th China National Science and Technology Week in May, an event designed to popularize science, hordes of visitors examined a model of Yutu 2, a lunar probe developed by Chen's academy.

"They were very interested in how Yutu 2 works on the far side of the moon. One visitor even asked me how the Queqiao relay satellite sets the communication link between Earth and the probe," Chen said.
