China is gearing up for the launch of the unmanned Shenzhou XXII spacecraft on Tuesday from the Jiuquan Satellite Launch Center in Northwest China, as announced by the China Manned Space Agency. The agency confirmed that the propellant injection for the Long March 2F carrier rocket, which will propel the spacecraft, has been successfully completed. The Shenzhou XXI crew aboard the Tiangong space station remains in good health, according to the agency’s statement released on Monday afternoon. Zhou Yaqiang, from the agency’s general technical bureau, revealed that Shenzhou XXII will be fully loaded with cargo, including essential provisions for astronauts and equipment necessary for the operations of the Tiangong space station. Originally slated to transport the Shenzhou XXII crew to Tiangong in April 2026, the spacecraft’s mission was adjusted due to the discovery of tiny cracks on the viewport window of the Shenzhou XX return capsule, likely caused by space debris. This rendered the capsule unsafe for use, prompting the need for Shenzhou XXII as a standby crew ship. The Shenzhou XX astronauts, who spent a record-breaking 204 days in orbit, returned safely to Earth on November 14 using the Shenzhou XXI spacecraft, nine days later than planned. Their successful return was facilitated by preplanned contingency measures, including the maintenance of a backup rocket and crew spacecraft, ensuring a rapid response in case of in-orbit emergencies.
