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).[4] The rocket is based on the Long March 7 with its first stage and two boosters, along with the existing liquid hydrogen burning third stage of the Long March 3A/3B/3C and 7A as its second stage. The boosters are omitted in the "core only" variant that first flew on its second launch in February 2022.[1]
A planned 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.[5]
The maiden flight of the Long March 8 was launched on 22 December 2020 from the Wenchang Spacecraft Launch Site.[6]
