Tianzhou-9 Cargo Spacecraft Completes Controlled Reentry, Mission Ends
Summary: China's Tianzhou-9 cargo spacecraft completed a controlled reentry into Earth's atmosphere on May 7, 2026 at 07:49 Beijing Time (23:49 UTC on May 6), with debris landing safely in a designated ocean area. The spacecraft had been providing supply services to the Tiangong space station since its launch in July 2025.
Tianzhou-9 launched on July 15, 2025 from the Wenchang Satellite Launch Center aboard a Long March 7 rocket, marking the fourth operational spacecraft in China's improved Tianzhou cargo series. During its mission, Tianzhou-9 completed multiple rendezvous and docking operations with the Tiangong space station, delivering essential supplies including food, propellant, and scientific experiment equipment for the Shenzhou-21 crew.
On May 6 at 04:34 UTC, Tianzhou-9 undocked from the aft port of the Tianhe core module and entered an independent flight phase. The Beijing Aerospace Flight Control Center then executed a controlled deorbit burn on May 7, causing the spacecraft to reenter over the South Pacific designated safety zone where it mostly burned up, with a small amount of debris falling into the planned ocean area.
The controlled reentry marks the standard end-of-life procedure for cargo spacecraft and the completion of the Tianzhou-9 mission, clearing the way for the upcoming Tianzhou-10 cargo mission to support continuous station operations.
