Tianzhou-10 Launches with Heaviest Chinese Cargo Payload to Date
Summary： Tianzhou-10 launched from Wenchang aboard a Long March 7 carrying the heaviest payload ever delivered by a Chinese cargo spacecraft to the Tiangong space station.
Tianzhou-10 lifted off in May 2026 (the precise date within the launch window awaits confirmation from the China Manned Space Agency) aboard a Long March 7 rocket (the specific vehicle serial number awaits official confirmation) from the Wenchang Space Launch Site on Hainan Island. The flight marks the tenth mission in the Tianzhou cargo series and another routine resupply run during the application and development phase of the Tiangong space station program.
According to public reports, the upmass delivered by Tianzhou-10 sets a new record for a Chinese cargo spacecraft, though the exact tonnage has yet to be formally released by the China Manned Space Agency. The improvement is widely attributed to incremental gains in the lift capability of the Long March 7 and further optimization of cargo bay packaging and loading procedures on Tianzhou — details that also await official confirmation.
Following launch, Tianzhou-10 is expected to rendezvous and dock with the Tiangong space station combination, transferring supplies to the on-orbit crew (the specific Shenzhou mission designation awaits official confirmation). Consistent with the standard Tianzhou mission profile, the spacecraft will remain attached for several months before undocking with waste materials and performing a controlled destructive re-entry. Specific rendezvous, on-orbit duration, and deorbit timing remain to be announced.
