description Queqiao-2 Overview
Queqiao-2 is a Chinese lunar relay satellite launched in 2024 by the China National Space Administration. It was placed in a highly elliptical orbit around the Moon to provide communications support for far-side and south-pole lunar missions. The satellite plays a crucial role in the Chang'e 6 mission, enabling data transmission between Earth and lunar probes operating beyond direct line-of-sight. It serves as an upgrade to the earlier Queqiao relay satellite.
help Queqiao-2 FAQ
When and how was Queqiao-2 launched?
China launched Queqiao-2 on March 20, 2024, aboard a Long March-8 rocket from Wenchang in Hainan. The [China National Space Administration](https://www.cnsa.gov.cn/english/n6465652/n6465653/c10489434/content.html) describes it as an Earth-Moon communications relay.
Why does China's far-side lunar program need Queqiao-2?
The Moon keeps the same side facing Earth, so spacecraft on the far side cannot maintain a direct radio link to ground stations. Queqiao-2 relays commands and scientific data between those missions and Earth.
Which lunar missions does Queqiao-2 support?
It was designed to support Chang'e-4, Chang'e-6, and future south-pole missions such as Chang'e-7 and Chang'e-8. The relay system is especially important for missions that operate on the Moon's far side.
What orbit does Queqiao-2 use around the Moon?
Queqiao-2 was placed into a highly elliptical orbit around the Moon rather than remaining in ordinary Earth orbit. That position lets it maintain useful communication geometry with both lunar missions and Earth.
