Long March 8 | Queqiao-2

Queqiao-2 is a Chinese artificial satellite to serve as a communications relay for future Chinese lunar far side missions that cannot communicate directly with the Earth, beginning with the Chang'e 6 lunar sample return mission in 2024. It will operate from a Distant Retrograde Orbit (DRO) of the Moon. The launch also carries the Tiandu-1 & 2 small satellites testing cis-lunar space navigation and inter-satellite communication techniques for CNSA’s Deep Space Exploration Laboratory (DSEL).

Long March 8 (Chinese: 长征八号运载火箭) is an orbital launch vehicle developed by the China Academy of Launch Vehicle Technology to launch up to 5000 kg to a 700 km altitude Sun-synchronous orbit (SSO). The rocket is based on the Long March 7 with its first stage and 2 out of its 4 boosters, along with the existing liquid hydrogen burning 3rd stage of the Long March 3A/3B/3C and 7A as its 2nd stage. A "Core Only" version omitting the boosters is also available.

The China Aerospace Science and Technology Corporation (CASC) is the main contractor for the Chinese space program. It is state-owned and has a number of subordinate entities which design, develop and manufacture a range of spacecraft, launch vehicles, strategic and tactical missile systems, and ground equipment. It was officially established in July 1999 as part of a Chinese government reform drive, having previously been one part of the former China Aerospace Corporation. Various incarnations of the program date back to 1956.
