Long March 10[3] (Chinese: 长征十号), also known as the “Next Generation crewed launch vehicle” (Chinese: 新一代载人运载火箭), and previously and unofficially as the “921 rocket” (Chinese: 921火箭) or the "Long March 5G" (a development of the Long March 5), 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. In 2022, the first flight was targeted for 2027.[4] By 2024, the first flight's target was moved up to 2025–26.[citation needed] In April 2024, it was announced that program development was complete.[5]
The standard Long March 10 will be capable of lifting 70 tonnes into low Earth orbit (LEO) and 27 tonnes into trans-lunar injection trajectories.[6]
There are also plans for a variant, the Long March 10A,[7] which is designed primarily for future low Earth orbit crew and cargo transport to the Chinese Space Station. It will be partially reusable and capable of lifting at least 14 tonnes into LEO.[6]
