China has launched the uncrewed Shenzhou 22 spacecraft in an emergency mission to assist three astronauts stranded aboard the Tiangong space station. The mission was prompted by damage to the previous return capsule, Shenzhou 20, which left the crew without a reliable way to return to Earth.
Shenzhou 22 lifted off successfully on November 25, 2025, and docked with the space station just hours later. The spacecraft is designed to act as a lifeboat and bring the crew safely back to Earth. It is also carrying essential supplies and spare parts for the space station. The astronauts are expected to return home safely using Shenzhou 22 around April 2026.
The emergency arose when a window on Shenzhou 20 was damaged, most likely by space debris. As a result, the rotation schedule of crews was disrupted. The most recent crew had to use Shenzhou 21 to reach Tiangong, leaving the existing astronauts without a dedicated return vehicle. Shenzhou 22’s launch restored a safe return path, ensuring the crew’s safety.
This rapid response demonstrates China’s growing capability in space operations and highlights the risks posed by debris in orbit. Space agencies worldwide have long acknowledged the dangers of orbital debris, which can damage spacecraft and endanger astronauts. The Shenzhou 22 mission showcases both the challenges of human spaceflight and China’s preparedness to handle emergencies in orbit.
China’s Tiangong space station has been a key focus of the country’s ambitious space program. The station, orbiting around 400 kilometers above Earth, hosts regular missions involving experiments in microgravity, technology tests, and space science. The Shenzhou 22 mission adds an important safety dimension, showing that even in emergencies, the astronauts’ well-being remains a top priority.
