About the Demo Flight Mission
- Type: Test Flight
- Orbit: Low Earth Orbit
First launch of the Long March 10B rocket and first ever successful rocket booster recovery of a Chinese launch vehicle.
Payloads on board is TBD.
Launch Pad & Location
Commercial LC-2
Wenchang Space Launch Site, People's Republic of China
The Commercial LC-2 launch pad has hosted 7 rocket launches, including 7 orbital launch attempts. The Wenchang Space Launch Site, People's Republic of China launch site has been the location for 68 total rocket launches.
The Wenchang Space Launch Site is a rocket launch site located in Wenchang on the island of Hainan, in China.
Formally a suborbital test center, it currently serves as China's southernmost spaceport. The site was selected for its low latitude, 19° north of the equator, allowing for larger payloads to be launched. It is capable of launching the Long March 5, the heaviest Chinese rocket. Unlike launch facilities on the mainland, Wenchang uses its seaport for deliveries.
China Aerospace Science and Technology Corporation Long March 10B Rocket
The Long March 10B is a reusable launch vehicle based on the 1st stage of the Long March 10A, in turn derived from a single 1st stage core of the Long March 10, with 7 YF-100 series kerosene/liquid oxygen staged-combustion cycle engines on the 1st stage. Like the Long March 10A, the 10B’s 1st stage is designed to be recovered downrange by a recovery barge equipped with an arrestor net and support frame, with the 1st stage landing on the net’s cables using its grid fins.
The 2nd stage, however, uses a single YF-219 gas generator cycle methane/liquid oxygen engine with 140 tonnes of thrust.
The Long March 10B became China's first orbital launch vehicle with its first stage booster being recovered, during its first launch on 10 July 2026.

Booster Landing & Recovery
Core LM-10B F1
The Long March 10B first stage booster has landed on Ling Hang Zhe after its 1st flight. Reusable booster LM-10B F1 last flew on 07/10/2026
and has completed 1 successful launch and landing missions. First stage booster used on the 1st flight of CASC/CALT's Long March 10B rocket. Grid fins and hooks are installed for an attempted recovery on the LHZ landing ship's arresting net.
It became the first Chinese orbital launch vehicle booster to be recovered on 10 July 2026.
Ling Hang Zhe - LHZ
Chinese rocket recovery ship operated by the China Aerospace Science and Technology Corporation for catching of first stage boosters of the Long March 10 series of rockets. It uses an "arresting net" installed on a high frame that catches hooks installed on the 1st stage boosters with cables.
Autonomous Spaceport Drone Ship - ASDS
An autonomous spaceport drone ship (ASDS) is an ocean-going vessel derived from a deck barge, outfitted with station-keeping engines and a large landing platform. Construction of such ships was commissioned by aerospace company SpaceX to allow for recovery of rocket first-stages at sea for high-velocity missions which do not carry enough fuel to return to the launch site after lofting spacecraft onto an orbital trajectory.
About China Aerospace Science and Technology Corporation
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.
