Queqiao-2, launched on March 20, has proven its capacity for relay communications essential for the upcoming fourth phase of China's lunar exploration project, as well as other future lunar missions. This announcement follows successful communication tests conducted with the Chang'e-4 probe, currently active on the moon's far side, and upcoming tests with the Chang'e-6 probe, scheduled for launch.
Following a successful deployment into a highly elliptical orbit near the moon on April 2, Queqiao-2 has also been instrumental in assisting the operations of two additional satellites, Tiandu-1 and Tiandu-2. These satellites, which share the same stable frozen orbit, focus on advanced communication and navigation technology testing.
Significantly, Queqiao-2 enhances capabilities beyond its predecessor, Queqiao, with a closer lunar orbit that improves data transmission speeds and extends communication coverage, particularly over the moon's south pole. This strategic placement also results in fuel savings, increasing the satellite's operational longevity.
In anticipation of supporting the Chang'e-6, Chang'e-7, and Chang'e-8 missions, Queqiao-2's deployment is critical for the communication needs of future lunar surface missions focused on the moon's south pole and far side. The CNSA has scheduled the launches of these missions between 2024 and 2028, aiming to establish a foundational lunar research station to facilitate extensive lunar environmental exploration.
