Tianzhou-10 Sets 12-Month Space Station Docking Record, China's Cargo Resupply Enters "Annual Mode"
Summary: Tianzhou-10 cargo spacecraft will remain docked to China's Tiangong space station for approximately 12 months, setting a new record for the Tianzhou series and marking the transition to an "annual resupply mode" for China's space station operations.
A New Docking Duration Record
According to reports from East Money Finance and CCTV, Tianzhou-10's extended docking duration of approximately 12 months sets a new record for the Tianzhou cargo spacecraft series.
Previously, Tianzhou-2 through Tianzhou-5 had docking durations of approximately 6 months. Starting from Tianzhou-6, as cargo uplift capacity improved, the docking duration was extended to 9–10 months. Tianzhou-10's 12-month stay marks China's space station cargo resupply officially entering an "annual mode."
The Tianzhou cargo spacecraft is 10.6 meters in length and uses a modular design consisting of a cargo module and a propulsion module. It is the core carrier for China's Tiangong space station supply missions. During its mission, it primarily carries out cargo supply, space science and technology experiments, disposal of waste materials through controlled reentry, and supports the space station in orbital maintenance and attitude control during its docking period.
Record-Breaking Mission: 67 Scientific Payloads, 41 Experiments
According to reports from Yunnan Net and other media, Tianzhou-10 carries 67 items of scientific payloads, experimental units, samples, and consumables totaling approximately 768 kg.
After these materials are delivered to China's space station, they will be promptly transferred and stored. The following 41 in-orbit scientific experiments will be conducted in phases using the station's research facilities:
- Space life science and biotechnology
- Microgravity physical science
- New space application technologies
- Space astronomy and Earth science
Next-Generation Equipment: 3rd Spacesuit and New Treadmill
Tianzhou-10 carries several next-generation facilities:
- Third set of new extravehicular spacesuit: Will achieve a complete replacement and upgrade of existing suits, enhancing EVA capability
- New space treadmill: Better meets astronauts' in-orbit exercise needs
- Propellant resupply: Approximately 700 kg of propellant for the space station
Fast Rendezvous: 3-Hour "Space Express Delivery"
Tianzhou-10 adopted a 3-hour autonomous fast rendezvous and docking scheme. After entering orbit and completing status settings, it successfully docked with the aft port of the Tianhe core module at 13:11 Beijing Time on May 11, 2026. The entire process from launch to docking took approximately 5 hours — significantly faster than the previous 6.5-hour fast rendezvous scheme, earning it the nickname "space express delivery."
Manufacturer: Shanghai Academy Develops Efficient Production Model
The Tianzhou spacecraft is manufactured by the Shanghai Academy of Aerospace Technology under China Aerospace Science and Technology Corporation. According to People's Daily (Shanghai), during Tianzhou-10's development, the Shanghai Academy innovatively established an integrated "Shanghai efficient production, Beijing system integration, launch site testing, flight control long-term management" four-in-one model, reducing product delivery cycles by 40% and successfully achieving the transition from single-piece customization to mass production.
This launch marks the 10th flight of the Long March 7 Y-11 carrier rocket, the 641st flight of the Long March series of rockets, and the 10th flight of the Tianzhou spacecraft series.
