China’s Shenzhou 21 Crew Returns to Earth After Record-Breaking 210-Day Mission
Three astronauts — including the most spacewalked Chinese astronaut ever — touched down in Inner Mongolia on May 29 in a dramatic end to a mission that involved spacecraft swaps, orbital emergency response, and a raft of pioneering science experiments aboard the China Space Station.
The Landing
The Shenzhou 21 crew returned to Earth at 8:11 PM Beijing Time (12:11 UTC) on May 29, 2026, parachuting to a safe landing at the Dongfeng landing site in the Gobi Desert of Inner Mongolia. The three taikonauts — Commander Zhang Lu, spaceflight engineer Wu Fei, and payload specialist Zhang Hongzhang — were extracted from the Shenzhou-22 return capsule in good health, according to the China Manned Space Agency (CMSA).
Their mission lasted 210 days — the longest single-crew duration ever achieved by China, surpassing the previous record by a comfortable margin. (The precise elapsed time from launch to landing was 209 days, 20 hours, and 26 minutes.)
All three crew members were reported in good physical condition. The recovery teams conducted on-site medical checks before transporting the crew to Beijing for an extended post-flight rehabilitation period.
A Mission of Firsts
Commander Zhang Lu (on his second spaceflight, having previously flown Shenzhou 14 in 2022) set a new Chinese record for most extravehicular activities (EVAs) by any Chinese astronaut — seven spacewalks in total across his two missions. During Shenzhou 21, he led multiple complex EVAs outside the China Space Station (CSS) and notably brought back an apple from orbit as a personal tribute to China’s science and engineering workers.
Spaceflight engineer Wu Fei, on his maiden flight, became the youngest Chinese astronaut ever to perform a spacewalk and completed three EVAs during the mission — an extraordinary achievement for a first-time flyer.
Payload specialist Zhang Hongzhang oversaw the crew’s scientific payload, including experiments he personally co-designed before launch.
Behind the Scenes: The Shenzhou-22 Swap
Perhaps the most unusual aspect of this mission was that the crew did not return in the spacecraft they launched in.
Shenzhou 21 launched on October 31, 2025, aboard a Long March 2F/G rocket from the Jiuquan Satellite Launch Center. The spacecraft docked with the CSS and the crew took up residence aboard the Tiangong station alongside the departing Shenzhou 20 crew.
But trouble struck the Shenzhou 20 return vehicle. During its orbital stay, the return capsule’s viewport was damaged, suspected to be caused by a micrometeoroid or space debris impact — a growing hazard in low Earth orbit. CMSA made the decision to loan Shenzhou 21’s spacecraft to the Shenzhou 20 crew for their return journey, which took place safely on November 14, 2025.
This left the Shenzhou 21 crew without a return vehicle. China responded by launching Shenzhou-22 on November 25, 2025 — an emergency return vessel — to serve as the crew’s lifeboat for the remainder of their stay. It was the first time China had launched a spacecraft specifically as a contingency rescue vehicle.
The Shenzhou 21 crew ultimately returned safely aboard Shenzhou-22, bringing a unique chapter in Chinese spaceflight operations to a close.
Science on the China Space Station
During their six-plus months in orbit, the crew conducted a wide range of scientific experiments across the CSS’s laboratory modules, several of which were firsts for the Chinese space program:
- Closed-environment mice breeding: The first successful multi-generational breeding of mice in microgravity aboard the CSS, a key step toward understanding mammalian reproduction in space for future long-duration missions.
- Low-defect indium selenide crystals: Growth of high-quality semiconductor crystals in microgravity, with potential applications in next-generation electronics and infrared detectors.
- Aeroponic cherry tomatoes and wheat: Soilless cultivation experiments testing closed-loop life support systems for future deep-space habitats.
- Ionic liquid propellant ignition: Testing of electrospray thruster technologies for more efficient satellite propulsion.
- Facial micro-movement health monitoring: A non-invasive system using subtle facial muscle movements to track astronaut health and fatigue levels in real time.
These experiments contribute to China’s broader ambitions — including a crewed lunar landing by 2030 and the longer-term goal of a human mission to Mars in the 2030s–2040s.
Looking Ahead
The safe return of the Shenzhou 21 crew marks another steady step forward for the Chinese human spaceflight program. With the CSS now in full permanent occupancy mode, China’s astronaut corps is rotating crews at regular intervals, pressing forward with science, technology demonstrations, and deep-space preparation.
For Commander Zhang Lu, the apple he carried back from space is now a symbol — a small token of gratitude from orbit to the thousands of engineers, technicians, and scientists who make China’s space program possible.
For China, the mission demonstrated something larger: the ability to handle in-flight anomalies (a damaged spacecraft), execute contingency launches, and adapt on the fly — skills essential for any nation with serious deep-space ambitions.
