"China's Queqiao-2 Satellite Paves the Way for Lunar Exploration"

China's experimental lunar satellites, Tiandu-1 and Tiandu-2, have begun tests for future lunar communication and navigation services, transmitting images of the moon's far side and Earth. The satellites, launched alongside the Queqiao-2 lunar communications relay satellite, are part of China's preparations for upcoming lunar missions and the planned International Lunar Research Station. The tests will inform the design and construction of lunar infrastructure, including a Queqiao satellite constellation for communication, navigation, and remote sensing.
