Long March 8(Chinese:Trường chinh số 8 tên lửa vận chuyển) is an orbitallaunch vehicledeveloped by theChina Academy of Launch Vehicle Technologyto launch up to 5000 kg to a 700 km altitudeSun-synchronous orbit(SSO).^[4]The rocket is based on theLong March 7with its first stage and two boosters, along with the existing liquid hydrogen burning third stage of theLong March 3A/3B/3Cand7Aas 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 bepartially reusableby featuring acombined booster recoveryof 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 theWenchang Spacecraft Launch Site.^[6]

CZ-8A variant[edit]

An upgraded version of the Long March 8, theLong March 8A(Chinese:Trường chinh số 8 giáp tên lửa vận chuyển), will debut in 2024 with increased capability of up to 7 tonnes to a 700 km altitudesun-synchronous orbit.It implements a larger 3.35 meters diameter liquid hydrogen/liquid oxygen second stage, coupled with 2 upgraded version of theYF-75Dengines (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.
