Description:


CZ-8A

  • Long March 8 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 dual engine first stage and single engine boosters, along with the existing liquid hydrogen burning third stage of the Long March 3A/3B/3C and 7A as its second stage.
  • Whereas the LM-7 uses 4 boosters, the LM-8 normally uses just 2. The boosters are omitted in the "core only" variant that first flew on its second launch in February 2022.
  • In 2018 it was planned that a future launch vehicle variant of the Long March 8 will be partially reusable by featuring a combined booster recovery of the first stage and the boosters as a single unit
  • The maiden flight of the Long March 8 was launched on 22 December 2020 from the Wenchang Spacecraft Launch Site.
    The "core only" variant first flew in February 2022

CZ-8A

An upgraded version of the Long March 8, the Long March 8A, has successfully debuted on February 11, 2025 with increased capability of up to 7 tonnes to a 700 km altitude sun-synchronous orbit.

  • Its hydrolox 2nd stage has a larger diameter (to match the 3.35 meters diameter core stage), and has 2 upgraded versions of the YF-75D engines (known as the YF-75H) with increased thrust to 10 tonnes each through measures such as increased turbopump speeds.
  • The Long March 8A can also use a larger 5.2 meters diameter payload fairing.
