Long March 10 (Chinese: 长征十号), also known as the “Next Generation crewed launch vehicle” (Chinese: 新一代载人运载火箭) or “921 rocket” (Chinese: 921火箭), is a Chinese super-heavy carrier rocket for crewed lunar missions that is currently under development. The nickname "921" refers to the founding date of China's human spaceflight program. Like the Long March 5, it uses 5-meter (16.4 ft) diameter rocket bodies and YF-100K engines, although with 7 engines on each of 3 cores. The launch weight is 2187 tonnes, delivering 25 tonnes into trans-lunar injection. The proposed crewed lunar mission uses two rockets; the crewed spacecraft and lunar landing stack launch separately and rendezvous in lunar orbit. Development was announced at the 2020 China Space Conference. As of 2022, the first flight of this triple-cored rocket is targeted for 2027.
A derivative of the Long March 10 with no boosters and only 2 stages, 7 YF-100K engines on the first stage and a single YF-100M engine on the second stage, is also being planned for future Low Earth orbit crew and cargo transport missions to the Chinese Space Station. This version has a capability to Low Earth Orbit of at least 14 tonnes. The first stage is planned to be recoverable and reusable.
