The Magpie Bridge constellation project, to be completed in three decadal phases, finishing around 2050. The project will not only establish a Lunar-Earth communications and control network but will also feature a constellation of remote-sensing satellites orbiting the moon.

More information on the two Tiandu satellites that were launched alongside the Queqiao-2 (Magpie Bridge 2) relay satellite.

Both Tiandu satellites will be used to verify new space communication and navigation technologies. Tiandu-1 weighs 61kg and is equipped with a dual band (Ka/Ku?) communications device, a laser angle reflector, a router, etc. Tiandu-2 weighs 15kg and carryies a communications payload only. The two satellites will enter an elliptical orbit around the moon and carry out data transmission and data forwarding tests, as well as tests on a high-precision orbit determination system. These technologies are crucial for the future Magpie Bridge lunar constellation project, which will establish a Lunar-Earth communications and control network and a remote-sensing constellation orbiting the moon.

The chief engineer of the lunar exploration project (Mr. Wu Weiren) said that a deep space broadband network will be extended to the moon, providing data links for a lunar remote sensing and navigation constellation as well as internet connectivity to taikonauts living on the moon, so that they can watch sports and TV shows. This is the first step toward a larger deep space communications network that will go beyond the moon and deeper into the solar system.

The construction of the final assembly testing building (Sanping Plant/三平厂房) at the Hainan Commercial Spaceport is now in full swing. Once finished, the 10,000-square-meter building can accommodate pre-launch final testing on two rockets concurrently.

, the improved Long March 8 variant will have its maiden flight in June of 2024.

Compared to the basic LM-8, the improved variant will have a larger diameter final stage (increased from 3m to 3.34m) and a larger fairing (increased from 4.2m to 5.2m).
