Summary: China is enhancing its lunar exploration capabilities with the launch of the Tiandu-1 and Tiandu-2 satellites, which are set to test new technologies essential for a future lunar navigation and communication system. This system, aimed at supporting both robotic and manned missions to the moon’s surface, will confront challenges like establishing stable inter-satellite links and dealing with solar radiation. The initiative is part of China’s broader vision for space exploration and leadership, with the goal of establishing a lunar base through the International Lunar Research Station and landing astronauts on the moon by 2030.
In a significant move to cement its place as a leader in space exploration, China is ramping up efforts to deploy advanced satellites that will form the backbone of a new lunar communication and navigation network. The imminent launch of the Tiandu-1 and Tiandu-2 satellites will be a testbed for key technologies paving the way for an expansive Queqiao constellation designed to overcome the lunar surface’s communication challenges, particularly for missions to the far side and the south pole of the moon.
The pilot satellites Tiandu-1 and Tiandu-2 come equipped with sophisticated payloads, allowing them to test satellite-to-ground laser ranging and inter-satellite microwave ranging. These preliminary tests are crucial in developing a seamless communication infrastructure that would enable both human and robotic presences on the moon’s surface, where direct line-of-sight with Earth is obstructed.
These initial forays into building a lunar satellite constellation underscore China’s strategic investment into space infrastructure, seen as pivotal for enhancing international collaborations and extending its influence in space. China’s ambitious plan includes fostering the International Lunar Research Station and envisions astronauts on the lunar surface within this decade.
The move coincides with the anticipated deployment of Queqiao-2, a new lunar satellite set to support an array of Chang’e missions and potentially shift the dynamics of lunar exploration. The Tiandu satellites are the brainchild of China’s recently established Deep Space Exploration Laboratory, reflecting the country’s drive to blend technological innovation with space diplomacy. China’s pace in developing this space-based infrastructure may indeed set a new benchmark for global lunar exploration endeavors.
